Substrate tips

Maintain the substrates

Keep substrates in their sealed wrapping material while they are in storage, and store rolls vertically to avoid the migration of plasticizers in some materials.
Move substrates from the storage area to the print production area at least 24 hours before use, so that they can adapt to its temperature and humidity.

General tips

Handle unprinted and printed substrates with care, and preferably with cotton gloves, to avoid fingerprints. For heavy rolls, use a forklift, and two people wearing security shoes.
Before loading a roll:
  • Check that temperature and humidity in the room are within the recommended ranges for the printer. See Environmental specificationsEnvironmental specifications.
  • Check that neither the roll nor its core are bent or deformed, which may cause the substrate to jam in the printer.
  • If the roll has been stored in a place not offering the recommended environmental conditions, allow some time for it to adapt to the temperature and humidity of the printer's environment.
  • Check which is the correct side for printing, by reading the label inside the core or the note inserted into the package.
  • Check that the substrate is correctly attached to the input core. Otherwise, the Internal Print Server will report an error.
  • Check the substrate thickness.
    • Up to 0.4 mm: Print normally.
    • 0.4 to 2 mm: Raise the carriage beam to a custom position. Edge holders are not needed and should not be used.
    • More than 2 mm: Not supported.
While loading a roll, ensure that the leading edge is parallel and straight across the output core, and attached evenly (start taping the substrate to the core at the center, then move towards the edges).
Also ensure that the side edges of the input and output roll are properly aligned. An incorrectly loaded roll may cause waves or cockles in the substrate, leading to ink smearing and printhead crashes.
After you have loaded a roll:
  • If you intend to use substrate edge holders, do not use edge holders from another printer, use only the edge holders that came with your printer.
  • Check the correct carriage beam position for printing: customized position for thick substrates, printing position for others. See Set the carriage beam position.
  • Check that you are using the correct substrate preset in the Internal Print Server and the correct ICC profile and other settings in the RIP.
  • HP substrates are optimized to provide the best out-of-the-box printing experience with your printer.
  • Use the Internal Print Server to check that any calibrations appropriate for your substrate have been done: printhead alignment, color calibration. See Printer calibrationPrinter calibration.
  • Do not cut off pieces of substrate while the substrate is loaded into the printer. This may cause the remaining substrate to jam.
You can find further information on the Web:
  • The specifications, finishing, processing, and warranty information for each individual HP substrate are available from http://www.globalBMG.com/hp/signagemedia and http://www.globalBMG.com/hp/HPMediaWarranties.
  • HP Image Permanence information is available from http://www.globalBMG.com/hp/printpermanence.
  • HP offers to recycle some substrates through the HP Take-Back Program, such as HP HDPE Reinforced Banner, HP Light Textile Display Banner, HP Heavy Textile Banner, HP Everyday Matte Polypropylene, 3-in Core, and HP DuPont Tyvek Banner. Recycling opportunities for these products may not exist in all areas. You should consult local recycling resources about recycling these products. For recycling in the USA, please go to the HP recycling services site, http://www.hp.com/go/recycleLFmedia/.
    HP offers to recycle some other substrates through the standard paper recycling process, such as HP White Satin Poster Paper, HP Photo-realistic Poster Paper, HP Coated Paper (3-in core), HP Universal Coated Paper (3-in core), HP Universal Heavyweight Coated Paper (3-in core), HP Heavyweight Coated Paper (3-in core), and HP Super Heavyweight Plus Matte Paper (3-in core).

Color consistency

Your printer has been designed to provide an excellent experience in terms of color consistency and repeatability. This allows large jobs such as fleet graphics and wall coverings to be printed in tiles or panels, with confidence that, when the finished panels are placed edge to edge, the colors will match at the joins.
The color variation within a printed job has been measured to be within this limit:
Maximum color difference (95% of colors) <= 2 dE 2000
note:
This is based on reflective measurements on a 943 color target under CIE standard illuminant D50, and according to the standard CIEDE 2000 as per CIE Draft Standard DS 014-6/E:2012. 5% of colors may experience variations above 2 dE 2000. Backlit substrates measured in transmission mode may yield different results.
Color matching is dependent on many external factors. Take the following points into account to achieve this level of consistency:
  • If a large job is being printed in panels, more than one roll may be required. All rolls should be from the same batch, and stored under correct conditions according to the manufacturer’s specifications.
  • Operating conditions (temperature and humidity) should be kept constant during the printing of the entire job.
  • Ensure that a printhead check and clean routine has been run prior to starting the job. If any printhead changes are required during the job, printhead alignment and color calibration should be done.
See also Color calibrationColor calibration.

Substrate configurations

The substrate can be loaded in a variety of different configurations to suit your different needs. Before loading, you must go to the Internal Print Server and select Substrate Load/Unload, then select the configuration you intend to use.
The basic configurations are illustrated below. These configurations can be used for single-roll or dual-roll printing.
  • The roll-to-roll configuration is suitable when you do not intend to cut and take away some prints or the output roll in the middle of a print job being done using a particular input roll. The substrate cannot be cut in mid-roll.
  • The roll-to-free-fall configuration is suitable when you want to cut and remove one or more prints as soon as they come out of the printer. The substrate is kept under tension between the input roll and the tension roller; but it can be cut after the tension roller because then it is no longer under tension.
  • The roll-to-collector configuration is suitable when you may want to cut the substrate and remove the output roll before finishing the print job being done using a particular input roll. The substrate is kept under tension between the input roll and the tension roller; but it can be cut after the tension roller because then it is no longer under tension.

Prepare to print

The following steps must be followed before the printer can print:
  1. Go to the Internal Print Server and select Substrate Load/Unload to open the Printer Configuration window.
  2. Select the printer configuration that you intend to use; the on-screen help will appear on the left.
    note:
    The Skip Substrate load check box should be checked only if the printer has just previously had the same configuration (i.e. the same substrate, same profile), and because of a severe system error, you had to restart the printer.
  3. Load the substrate. Substrate loading instructions are displayed in the Internal Print Server window. For more detailed instructions, see Load a roll onto the spindle and Load a roll into the printer.
  4. Select the substrate type.
  5. Press the Finish button in the Internal Print Server to start the substrate check, then enter the substrate type in the Loaded Substrate window.
note:
If the printer has been idle overnight with substrate loaded, and exposed to high or low temperatures, advance the substrate 13 to 25 cm before printing, to avoid printhead crashes or ink smears on the substrate.

The substrate edge holders

The purpose of the substrate edge holders is to prevent the substrate edges from lifting up and jamming while printing. If you experience this kind of problem while printing, you can try using the edge holders to overcome it.
The edge holders are highly recommended when printing on textile substrates.
note:
The edge holders are not recommended when printing on substrate that is more than 0.4 mm thick.
note:
The edge holders may be easier to deploy if you raise the carriage beam (see Set the carriage beam position); however, they can be deployed without raising the carriage beam.
The correct position is illustrated below. The substrate should be free to move, and should not touch the ends of the edge holder.
  caution:
Wrongly positioned edge holders could severely damage the printheads and carriage.
note:
If the substrate is loaded with the right edge outside the 161 cm position on the spindle ruler, or the left edge outside the −162 cm position, the edge holders cannot be used because there is not enough space for them.

Install an edge holder

To install an edge holder, stand at the front of the printer and attach the front of the edge holder (marked with the number 1 on the blue part) to the front of the platen. Ensure that the substrate is aligned with the marks on the edge holder.
Then go to the rear of the printer, open the loading table, pull the rear of the edge holder towards you, and attach it to the rear of the platen. A built-in magnet helps to position the edge holder correctly on the platen. Ensure that the substrate is aligned with the marks on the edge holder.
  caution:
Place the edge holder carefully. It should remain perfectly straight, otherwise it could damage the printheads and carriage.
note:
Once installed, an edge holder cannot be slid sideways. If you want to move it sideways, you must remove it and reinstall it in the new position.

Replace an edge holder strip

Replacement edge holder strips come with the Cleaning Kit. Replace the strip if it is broken (for example, by an impact) or deteriorated (for example, by accumulated ink).
  1. If it is installed in the printer, remove the edge holder from the platen, disengaging it from the back and then from the front.
  2. Loosen but do not remove the screw at each end of the edge holder.
  3. Remove the old strip, insert the new one, and tighten the screws.
  4. Replace the edge holder on the platen, if you intend to use it.

Load a roll onto the spindle

Single-roll printing

The spindle has a pneumatic connector at one end and a gear at the other.
  1. Check that the gear is on the correct side (which depends on the intended winding direction).
  2. Insert the spindle into the roll.
    note:
    The spindle is quite heavy in order to ensure stiffness and so avoid skew and wrinkles, so two people are recommended for this operation.
  3. Note the position of the end of the roll on the scale marked on both sides from the center of the spindle. The input and output rolls should be positioned identically on their respective spindles.
    note:
    The rolls should be centered to reduce the risk of skew, wrinkles, and telescoping.
  4. Connect the air gun to the pneumatic connector on the spindle, and inflate the spindle so that it cannot move inside the roll.
note:
If the substrate is telescoped on the input roll, there is a risk of substrate jams and damage to the printheads. Try to straighten the edges of the substrate to minimize telescoping on the input roll before loading it into the printer.
note:
Check that the substrate is attached to the input core.
The roll is now ready to be loaded into the printer.
note:
If you are a regular user of different substrate types, you can change rolls more quickly if you preload rolls of different substrate types on different spindles. Extra spindles are available for purchase, see AccessoriesAccessories.
note:
A dual-roll spindle can be used for single-roll printing. Lock the lever and inflate both valves.

Dual-roll printing

You can print on two rolls at the same time by using the dual-roll spindle.
Loading the dual-roll spindle
  1. Insert the first roll on the spindle.
  2. Insert the second roll on the spindle.
  3. Center both rolls, using the marks on both sides of the center of the spindle. The input and output rolls should be positioned identically on their respective parts of the spindle.
  4. Inflate the valves at both ends.
Use the Dual Roll Center Support to ensure that no part of the substrate path suffers from an excess of tension due to the weight of the substrate. When the weight of the substrate is high, the absence of this accessory could increase the risk of a printhead crash, which decreases printhead life as well as spoiling the current print. The Dual Roll Center Support needs to be calibrated; please refer to the dual roll guide, which you can find at http://www.hp.com/go/latex3000/manuals/.

Load a roll into the printer

The objective when loading substrate is to get a uniform tension across its width and length to minimize the risk of skew, wrinkles, and telescoping. There are four ways in which the substrate can pass through the printer:
  • Roll-to-roll configuration
  • Dual roll-to-roll configuration
  • Roll-to-free-fall configuration
  • Roll-to-collector configuration
For each configuration, there are two ways of loading the substrate:
  • Manual loading: this is recommended for rigid and narrow substrates
  • Assisted loading: this can be used to make loading flexible or wide substrates easier
    note:
    Assisted loading is not recommended with dual rolls.

Load a roll (roll-to-roll configuration)

The substrate roll is mounted on the input spindle (single or dual) and will be collected on the output spindle. The substrate goes from the input spindle (1) over the main roller (2), over the platen (3), over the front diverters (4) and then to the output spindle (5).
The above illustration shows the substrate loaded with the printed face outwards on both input and output rolls. You can also load substrate with the printed face inwards on either or both rolls, in which case the spindle will turn in the opposite direction. The printer asks you for the winding direction if it cannot detect it automatically.
Each of the spindles has its own motor. The motors maintain tension on the substrate. Some vacuum is applied at the level of the platen to keep the substrate flat. The substrate is moved forwards by the drive roller motor, on which there is a pinch mechanism to prevent the substrate from slipping.
Before loading a roll into the printer, you must have a roll loaded onto a spindle (the input roll) and an empty core loaded onto another spindle (the output roll). See Load a roll onto the spindle.
note:
For the output roll, use a single empty core the same length as the input core. Do not place two or more shorter cores on the same spindle, which could cause substrate-advance problems.
note:
The spindle and a roll of substrate can be heavy. You are recommended to use a forklift or some other equipment to move it into position; otherwise, lift one end into the printer, and then the other end.
  1. Go to the Internal Print Server and select Substrate Load/Unload, then select the correct configuration.
  2. In the Internal Print Server, choose from the list of substrate types the type that you have loaded.
  3. If they are installed, remove the substrate edge holders from the print platen so that they do not get in the way while loading the substrate.
      caution:
    Loading the substrate on top of the edge holders could severely damage the printheads and carriage.
  4. Bring the new roll on its spindle to the rear of the printer, with the geared end of the spindle on the left.
  5. Rest the ends of the spindle on the platforms provided at the rear of the printer; plastic pads are provided to absorb the impacts.
  6. In the same way, load the spindle with the empty core into the front of the printer. In this case, the geared end of the spindle should be on the right.
  7. All substrates can be loaded with the manual loading procedure (below). However, you may find it easier to use the assisted loading procedure if your substrate is flexible or wide.
Assisted loading
  1. Open the front door.
  2. Open the curing module latches.
  3. Open the curing module.
  4. Open the loading table latches.
  5. Open the loading table.
  6. Unwind a length of substrate.
  7. Place it on the loading table.
  8. Close the loading table.
  9. Rewind the substrate manually until the leading edge is close to the pinchwheels.
  10. Close the loading table latches.
  11. Go to the Internal Print Server and use the large blue button to advance the substrate until it reaches the output spindle. Ensure that the substrate advances smoothly and is not trapped by any obstruction. If necessary, help the substrate to advance and to pass through the curing module slot.
  12. Open the loading table.
  13. Align the substrate by checking that the substrate edge is in the same position on the input and output spindles. This can be done by using the rulers on the spindles or by measuring the distance between the right edge and the side plate.
  14. When the substrate is evenly tensioned and flat (no wrinkles or bumps), attach it to the empty core with adhesive tape. Tape it first in the center, and then at the left and right sides, making sure not to pull the substrate excessively or leave it wrinkled.
  15. If you are using them, place the substrate edge holders into position and attach them at the front.
  16. Close the curing module and latches, then the front door.
  17. If you are using them, attach the substrate edge holders at the rear.
  18. Close the loading table and latches.
  19. Go to the Internal Print Server and press the Finish button. The printer rotates both rolls to check their diameters, and it also checks the width of the roll, the winding direction, the vacuum, and the substrate advance calibration (this takes about a minute).
    note:
    The roll size appears at the bottom of the screen; to change it, click Change substrate settings.
    note:
    Some substrates (such as transparent substrates) cannot be measured by the printer in this way. In such cases, you will be asked to enter the Left Edge and Width fields yourself into the Internal Print Server. Use the ruler on the spindle to check these values.
  20. An alert about substrate-advance tracking may appear at this point. For more information on when you might want to turn off automatic tracking, see Substrate-advance compensationSubstrate-advance compensation.
  21. For more information on when you might want to change the carriage beam position, see Substrate tips.
Manual loading
  1. Use the Internal Print Server to raise the carriage beam to its loading position.
  2. Open the front door.
  3. Open the curing module latches.
  4. Open the curing module.
  5. Open the loading table latches.
  6. Open the loading table.
  7. Unwind a length of substrate.
  8. Place it in the print zone.
  9. Push the substrate through the printer until it reaches the output spindle.
  10. Align the substrate by checking that the substrate edge is in the same position on the input and output spindles. This can be done by using the rulers on the spindles or by measuring the distance between the right edge and the side plate.
  11. When the substrate is evenly tensioned and flat (no wrinkles or bumps), attach it to the empty core with adhesive tape. Tape it first in the center, and then at the left and right sides, making sure not to pull the substrate excessively or leave it wrinkled.
  12. If you are using them, place the substrate edge holders into position and attach them at the front.
  13. Close the front door and the curing module.
  14. If you are using them, attach the substrate edge holders at the rear.
  15. Close the loading table.
  16. Use the Internal Print Server to lower the carriage beam to its printing position.
  17. Go to the Internal Print Server and press the Finish button. The printer rotates both rolls to check their diameters, and it also checks the width of the roll, the winding direction, the vacuum, and the substrate advance calibration (this takes about a minute).
    note:
    Some substrates (such as transparent substrates) cannot be measured by the printer in this way. In such cases, you will be asked to enter the Left Edge and Width fields yourself into the Internal Print Server. Use the ruler on the spindle to check these values.
  18. An alert about substrate-advance tracking may appear at this point. For more information on when you might want to turn off automatic tracking, see Substrate-advance compensationSubstrate-advance compensation.
The printer is now ready to print.

Load a roll (dual roll-to-roll configuration)

The two substrate rolls are mounted on the rear dual-roll spindle and will be collected on the front dual-roll spindle. The substrate goes from the input spindle over the main roller, over the platen, over the front diverters and then to the output spindle.
note:
When using dual rolls, you are recommended to use the roll-to-roll configuration for best performance.
You can load substrate with the printed face inwards or outwards on the spindle, in which case the spindle will turn in the opposite direction. The printer asks you for the winding direction if it cannot detect it automatically.
Before loading two rolls into the printer, you must have both rolls loaded on the rear dual-roll spindle and two empty cores loaded on the front dual-roll spindle. See Load a roll onto the spindle.
If the rolls are of unequal lengths, the longer roll should be on the right as seen from the front of the printer; on the left as seen from the rear. That way, when the shorter rolls runs out, you can continue printing on the other roll.
note:
When one roll runs out, you should lock the differential in the middle of the spindle, using the lever on the left-hand side.
  1. Go to the Internal Print Server and select Substrate Load/Unload, then select the correct configuration.
  2. In the Internal Print Server, choose from the list of substrate types the type that you have loaded.
  3. If they are installed, remove the substrate edge holders from the print platen so that they do not get in the way while loading the substrate.
      caution:
    Loading the substrate on top of the edge holders could severely damage the printheads and carriage.
  4. If you intend to use the Dual Roll Center Supports, install them now, for both input and output spindles, and move them up to their calibrated positions to ensure that the substrate is later brought to the output spindle and properly wound.
      caution:
    The calibrated position should be set following the instructions provided with the accessory. An incorrect position could cause the carriage to crash (see There are wrinkles and ink smears on the substrateThere are wrinkles and ink smears on the substrate).
  5. You may find it helpful to lock the differentials on the input and output spindles while loading.
  6. Bring the new rolls on their spindle to the rear of the printer, with the geared end of the spindle on the left.
  7. Rest the ends of the spindle on the platforms provided at the rear of the printer; plastic pads are provided to absorb the impacts.
  8. In the same way, load the spindle with the empty cores into the front of the printer. In this case, the geared end of the spindle should be on the right.
Manual loading
note:
Assisted loading is not recommended in a dual-roll configuration.
  1. Use the Internal Print Server to raise the carriage beam to its loading position.
  2. Open the front door and the curing module.
  3. Open the loading table.
  4. Unlock the differential in the input spindle.
  5. Unwind a length of substrate from the first input roll and place it in the print zone.
  6. Push the substrate from the first roll through the printer until it reaches the output spindle.
  7. Unwind a length of substrate from the second input roll and place it in the print zone.
  8. Push the substrate from the second roll through the printer until it reaches the output spindle.
  9. Align the substrate by checking that the substrate edge is in the same position on the input and output spindles. This can be done by using the rulers on the spindles or by measuring the distance between the right edge and the side plate.
    note:
    You are recommended to align the edges of both rolls by the lines on both sides of the spindle’s center mark.
    note:
    If you are using the maximum width of 1.60 m per roll and the edge holders are not needed, the left roll should be moved 20 mm towards the center (leaving a gap of 20 mm between rolls) for an easier load.
    note:
    The substrate-advance sensor must be covered by the substrate (from 252 to 310 cm on the ruler).
  10. When the substrate is evenly tensioned and flat (no wrinkles or bumps), attach it to each empty core with adhesive tape. Tape it first in the center, and then at the left and right sides, making sure not to pull the substrate excessively or leave it wrinkled.
  11. If you are using them, place the three or four substrate edge holders into position and attach them at the front.
    note:
    When aligning the roll edges with the marks on the dual-roll spindle, the center edge holder (if needed) is shared by both rolls. If you position the rolls differently, and you are using edge holders, take into account the distance required for the edge holders.
  12. Close the front door and the curing module.
  13. If you are using them, attach the substrate edge holders at the rear.
  14. Close the loading table.
  15. Ensure that the spindle differentials are unlocked.
  16. Use the Internal Print Server to lower the carriage beam to its printing position.
  17. Go to the Internal Print Server and press the Finish button. The printer rotates the rolls to check their diameters, and it also checks the width of the roll, the winding direction, the vacuum, and the substrate advance calibration (this takes about a minute).
    note:
    Some substrates (such as transparent substrates) cannot be measured by the printer in this way. In such cases, you will be asked to enter the Left Edge and Width fields yourself into the Internal Print Server. Use the ruler on the spindle to check these values.
  18. An alert about substrate-advance tracking may appear at this point. For more information on when you might want to turn off automatic tracking, see Substrate-advance compensationSubstrate-advance compensation.
  19. For more information on when you might want to change the carriage beam position, see Substrate tips.
The printer is now ready to print.

Load a roll (roll-to-free-fall configuration)

The substrate roll is mounted on the input spindle; the printed substrate will be deposited on the floor in front of the printer. The substrate goes from the input spindle (1) over the main roller (3), over the platen, over the front diverters (5) and then to the tension roller (7), after which it continues to the floor.
You can load substrate with the printed face inwards or outwards on the spindle, in which case the spindle will turn in the opposite direction. The printer asks you for the winding direction if it cannot detect it automatically.
Before loading a roll into the printer, you must have a roll loaded onto the input spindle. See Load a roll onto the spindle.
note:
The spindle by itself is quite heavy, and a roll of substrate can be much heavier. You are recommended to use a forklift or some other equipment to move it into position; otherwise, lift one end into the printer, and then the other end.
To load the substrate, follow the same procedure as in the roll-to-roll configuration, except that the output spindle is not needed.
  1. Ensure that the tension roller lever is raised.
  2. Unlatch the tension roller at both ends.
  3. Move the roller to the front, so that you have more space to pass the substrate behind the roller.
  4. Pass the substrate through and push the roller backwards, taking care not to trap your fingers between the roller and the black substrate guide lying underneath and behind.
  5. Close the latches at both sides.
  6. Align the substrate by checking that the substrate edge is in the same position on the input spindle and tension roller. This can be done by using the rulers on the spindle and tension roller or by measuring the distance between the right edge and the side plate.
  7. Ensure that the substrate is evenly tensioned and flat (no wrinkles or bumps), and close the tension roller lever.
  8. Go to the Internal Print Server and press the Finish button as in the roll-to-roll configuration.

Load a roll (roll-to-collector configuration)

This configuration is similar to the roll-to-free-fall configuration, but with the addition of a collector roller and loop shaper.
note:
Do not try to load or unload the collector while printing.
Before starting to load the substrate, select a loop shaper of the correct length to match the substrate width. The following tubes are supplied so that you can make up loop shapers of many different lengths.
  • One 152-mm tube
  • Two 203-mm tubes
  • One 305-mm tube
  • One 610-mm tube
  • Two 1067-mm tubes
  • Two end flanges, to be placed at each end to avoid lateral displacement of the loop shaper during printing
For example, you can make up the following loop shapers.
  • 914 mm: 610-mm and 305-mm tubes
  • 1016 mm: 610-mm and two 203-mm tubes
  • 1270 mm: 1067-mm and 203-mm tubes
  • 1372 mm: 1067-mm and 305-mm tubes
  • 1524 mm: 1067-mm, 305-mm and 152-mm tubes
  • 1829 mm: 1067-mm, 610-mm and 152-mm tubes
  • 1981 mm: 1067-mm, 610-mm and two 152-mm tubes
  • 2032 mm: 1067-mm, 610-mm, 203-mm and 152-mm tubes
  • 2489 mm: two 1067-mm, 203-mm and 152-mm tubes
  • 2642 mm: two 1067-mm, 305-mm and 203-mm tubes
  • 3200 mm: two 1067-mm, 610-mm, 305-mm and 152-mm tubes
  1. Follow the whole loading procedure for the roll-to-free-fall configuration.
  2. Load an empty substrate core onto the output spindle. For dual-roll printing, load two cores of the same diameter onto a single spindle (it is not recommended to use a dual-roll spindle as the collector).
  3. Use the buttons in the Internal Print Server to advance the substrate's leading edge until it reaches the core on the collector.
  4. Tighten the substrate so that it is evenly tensioned, then attach the leading edge to the core with tape, first at the center and then at the sides. There should be no wrinkles or slackness across the substrate.
  5. Use the buttons in the Internal Print Server again to advance the substrate so that a substrate loop is produced between the tension roller and the collector.
  6. Place the loop shaper into the substrate loop.
    note:
    Loop detection is done in the center of the printer; so avoid putting your foot or any other object under the collector in the center.
  7. Go to the Internal Print Server and press the Enable collector button.
  8. Select the winding direction: Outwards is recommended, as it permits an output roll up to 300 mm in diameter. If you select Inwards, the diameter of the output roll is limited to 200 mm: with a fatter roll, the loop shaper would start to touch the roll.
    note:
    The winding direction cannot be changed on the fly: the collector has to be deactivated and reactivated.
  9. Press the Finish button.
The printer is now ready to print.

View information about the loaded substrate

Information about the loaded substrate is displayed at the bottom of the main screen of the Internal Print Server.
To see more information, select the Substrate menu and then Settings.

Unload a roll

  1. Check that the printing is not printing.
  2. Go to the Internal Print Server and select Substrate Load/Unload.
  3. Lift the loading table latches at the rear of the printer.
  4. If you need to raise the carriage beam, go to the Internal Print Server and select Carriage beam position > Move to substrate load position. The printer raises the carriage. This process takes about 2 minutes to complete.
    note:
    This step is optional. It may be feasible to unload some substrates without raising the carriage beam.
  5. When the carriage has been raised, cut the substrate
  6. Wind the substrate manually onto the output roll.
  7. Open the front latches and remove the output roll from the printer.
  8. Remove the spindle from the roll.
  9. Rewind the substrate manually onto the input roll.
  10. Open the rear latches and remove the input roll from the printer.
  11. Remove the spindle from the roll.
The printer is now ready for new input and output rolls to be loaded.

Substrate presets

Each supported substrate type has its own characteristics. For optimum print quality, the printer changes the way it prints on each different substrate type. For example, some may need more ink and some may require higher temperatures for drying and curing. So the printer must be given a description of the requirements of each substrate type. This description is called a substrate preset. The printer is supplied with substrate presets for some specific substrate types, and also with presets for some generic types.
As it is inconvenient to scroll through a list of all substrate types available, your printer contains substrate presets for only the most commonly used substrate types.
For your convenience, substrate settings from many substrate vendors have been collected at http://www.hp.com/go/mediasolutionslocator. You can check substrate availability using the HP Media Locator application that you will find there.
To install a new substrate preset that you have downloaded, go to the Internal Print Server and select Substrate > Presets management > Import label, then search for your .oms file and click Update. You can also export substrate presets using Export label.

Use a new substrate

Whenever you load a new substrate type into your printer, you must choose a substrate preset for it.
  1. If no specific preset for that substrate appears in the list, check the HP Media Solutions Locator (http://www.hp.com/go/mediasolutionslocator) in case a preset for your substrate is available there. Alternatively, get the specific preset from your substrate reseller or the substrate manufacturer.
  2. If no specific preset is available, try using a generic preset in the same substrate category.
  3. If you are not satisfied with the results, use the Add New Substrate wizard to create a new preset for your substrate. See Create a new substrate preset with the Add New Substrate wizard.
  4. For full control of your preset, clone a generic preset (or the preset obtained from the Add New Substrate wizard) and adjust the settings manually. See Edit a substrate preset. This is recommended for advanced users only.

Prepare the printer for a new substrate

  1. Whenever possible, try to ensure that your printer is in an optimum state before you create a new preset: run any pending maintenance task, in particular printhead checks and alignment.
  2. Stop the print queue and wait for the printer to finish the current job. No jobs should be sent to the printer until the new substrate preset is complete.
  3. Load your new substrate. The process of loading a substrate into the printer has been designed to be completely independent of the substrate type. When loading, follow the correct procedure and ensure that the roll width is specified, either automatically by the printer or by yourself. You may not experience the best possible results if there are significant differences between the specified and the actual roll width.
    note:
    You are recommended to use the roll-to-roll configuration when creating a new preset.
  4. Choose a suitable carriage beam printing position: see Set the carriage beam position.

Create a new substrate preset with the Add New Substrate wizard

The Add New Substrate guides you to work out the best settings for your substrate. It first requests some information about the substrate and your intended use of it, then prints some test prints and asks you to evaluate them. From this information, it creates the new preset.
To use the wizard, first ensure that the new substrate is loaded in the roll-to-roll configuration, then go to the Internal Print Server, select the Substrate tab, and then Create.

Material

The first question from the wizard asks for the primary material of which your substrate is made.
  • Self-Adhesive Vinyl includes cast self-adhesive vinyl, calendered self-adhesive vinyl, perforated self-adhesive vinyl, transparent self-adhesive vinyl, and reflective self-adhesive vinyl.
  • PVC Banner includes frontlit banner, backlit banner, scrim banner, scrimless banner, mesh banner with liner, blockout banner, truck curtain banner, tarpaulin, and PVC wall covering.
  • Paper includes coated paper, uncoated paper, photo paper, photorealistic paper, blue-back paper, paper wall covering or wallpaper, self-adhesive paper, and non-woven wall covering.
  • PP & PE Film & Banner includes polypropylene (PP) film, synthetic paper (such as Yupo), Tyvek, and PE or HDPE (polyethylene) banner.
  • PET Film includes polyester (PET) backlit film, polyester (PET) frontlit film, and polyester (PET) grey-back film.
  • Textile includes polyester textile and fabric, textile banner, backdrops, textile mesh with liner, frontlit textile, backlit textile, canvas, flag and voile *, cotton textile, textile wall covering, self-adhesive textile, and woven wall covering.

Application

The next question asks how you intend to use your substrate.
  • Frontlit means that the print will be viewed by light from in front of the substrate.
  • Backlit means that the print will be viewed by light from behind the substrate.

Optimized for

The next question asks whether you want to give priority to speed, quality, or neither.
  • Print Quality: You want the best possible print quality.
  • Print Speed: You want fast printing.

Test print

Next, the wizard shows you the proposed settings for the first test print. These settings are generated based on the information you have already given.
note:
If you are an advanced user and the suggested settings do not meet your expectations, you can select Advanced settings at any time and make manual changes. However, you are recommended to print the first test print as an indication of overall performance on your substrate.
note:
If you cancel the test print because you are experiencing substrate issues or print-quality issues such as banding, consider modifying the substrate preset, following the guidelines provided in Troubleshoot substrate issuesTroubleshoot substrate issues and Troubleshoot print-quality issuesTroubleshoot print-quality issues.
When the test print has been made, the wizard asks you some questions about it.
The print is organized into horizontal bands which are printed at a range of different ink densities. There are two different sections. The left part (Section A) is focused on color saturation and curing performance. The right part (Section B) is focused on the interaction of several ink densities with different levels of optimizer.
  1. Start with Section A. Check whether any of the bands is completely cured. Use the black 4-color patch for this purpose. Do a smudge test if possible. Check whether any curing defects are visible. One possible curing defect appears as a pattern of small round spots on the print, from the perforated plate through which the curing air passes.
    If you have found an ink density that is perfectly cured, choose this or a lower ink density in the Ink Density drop-down menu. Never select a ink density with curing defects.
    If none of the ink density bands is completely cured, or the ink density you prefer for your application is not cured, select NONE in the Ink Density menu. The wizard then generates another test print with different settings.
  2. When you have found a satisfactory ink density, you need to select the best amount of optimizer for this ink density.
    Within the ink density band you have selected, look at Section B of the print to determine the best amount of optimizer. Look at color-to-color bleed and smooth area fills. If you see several levels of optimizer performing equally well, you are recommended to choose the lowest amount without defects.
    If you cannot find any amount of optimizer giving satisfactory performance with the selected ink density, look at neighboring ink densities (usually lower, but could be higher in some rare cases). Consider changing the selected ink density if there is a combination without defects. If you do so, remember to change the ink density in the drop-down menu.
  3. Once you have found a good combination of ink density and optimizer, click Next to add the substrate and the printing condition you just selected. You can rename both. In some cases, several printing conditions are offered at once. You can deselect the options you are not interested in.
  4. You are recommended to perform color calibration immediately after completing the wizard, to ensure that the calibration process can cope with the selected ink density.
  5. The new preset is now loaded into the Internal Print Server. You can print your own test prints or create an ICC profile with your RIP software.
note:
If you need to provide different printing conditions or change those currently available in the new preset, you can select Edit from the Substrate menu.

Edit a substrate preset

Editing a preset has several purposes.
  • You can assign a name of your own choice to a particular substrate.
  • You can adjust the preset to suit the precise characteristics of your substrate.
  • You can adjust the preset to your intended use of the substrate, which may range from highest-quality printing to fast production output.
To edit the technical characteristics of a custom substrate type, go to the Internal Print Server and select Substrate > Edit. This allows you to change all the important settings in the substrate preset. It is recommended for advanced users only.
note:
You can change only the presets that you have created yourself. The presets supplied by HP cannot be changed.
  1. In the upper part of the Edit Substrate window, select the substrate category and the name of the specific substrate preset that you want to edit.
    note:
    Generic presets cannot be edited.
  2. In the central part of the window, select the number of passes, number of colors, and ink density; and name the combination to make it visible in the Print dialog.
  3. In the lower part of the window, change the settings for your named combination. Press Update print mode if you want to change an already-existing named combination.
In order to achieve a highly optimized preset for one specific purpose and substrate, you may need to adjust other settings to compensate. To achieve a balanced preset, you are recommended to use the Add New Substrate wizard or a generic preset.

Optimize the preset for higher print speed

Action

Reduce the number of passes.

Possible risks and compensations

  • Risk: Poor curing performance.
    • Compensation 1: Reduce the ink density by one or two levels for each level that the number of passes is reduced.
      Example: For most front-lit materials, 6-pass 100% ink > 4-pass 80% ink > 3-pass 60% ink.
    • Compensation 2: Slightly increase the curing airflow to eliminate minor curing artifacts.
    • Compensation 3: Increase the curing temperature if you choose not to compensate with the ink density.
      note:
      This is feasible only with substrates that do not show thermal deformation defects at higher temperatures.
  • Risk: When you reduce the number of passes, especially to 4 or fewer, some artifacts such as grain, bleed, and coalescence may become visible. It is possible to compensate to some extent with the following settings:
    • Compensation 1: Reduce the ink density as described above.
    • Compensation 2: Increase the optimizer ink level in 2% steps for each level that the number of passes is reduced.
      Example: 6-pass 12% optimizer > 4-pass 14% optimizer.
    • Compensation 3: Increase the drying lamp power in 10% steps for each level that the number of passes is reduced.
      Example: 6-pass 50% power > 4-pass 60% power.

Optimize for best print quality and/or widest gamut

Actions

  • Use a 6-color ink set.
  • Increase the number of passes.
  • Increase the ink density.

Considerations

  • A 6-color ink set enables smooth transitions; always use this option for best print quality.
  • Use an 8-pass print mode for best print quality with frontlit substrates.
  • Use a 14- or 18-pass print mode for best print quality with backlit substrates and textiles.
  • When using a high number of passes, substrates can be saturated above 100% ink (example: 130% frontlit, 300% backlit). Higher ink densities may increase gamut and color saturation, and, in backlit materials, increase opacity of printed areas.
note:
This is highly substrate-dependent.

Optimize for ink consumption

Actions

  • Reduce ink density.
  • Use a 4-color ink set.

Considerations

  • Reducing the ink density usually reduces the gamut and color saturation.
  • A lower ink density may permit a lower number of passes.
  • A 4-color ink set may reduce overall ink consumption, as the light cyan and light magenta inks are not used in printing.
    note:
    Some ink is still used from each printhead to maintain the health of the printhead.
  • A 4-color ink set is less resistant to some print-quality defects, such as contouring.

Recommended speeds per substrate type

Recommended ink densities per substrate type

Adjust the printing workflow for optimum color performance

  1. Check your substrate's color calibration status and calibrate it if recommended, by selecting Substrate > Color calibration in the Internal Print Server. See Printer calibrationPrinter calibration.
  2. Create ICC profiles for your substrate; see your RIP documentation for instructions.

Remove a substrate preset

To remove a substrate preset from your printer, go to the Internal Print Server and select Substrate > Remove. Then select the category and type of the substrate you wish to remove from a list of removable substrates.

Set the carriage beam position

The carriage beam position determines the vertical distance between the printheads and the platen. If it is too great, print quality will be impaired. If it is too small, there is a risk that the printheads will come into contact with the substrate, causing smears or damage.
  • The substrate-load position is not used for printing: it may be used for loading substrate or for maintenance tasks.
  • A custom position is used for thick substrates, or for substrates that wrinkle slightly due to heating.
    note:
    Try to avoid wrinkling by using substrates that do not wrinkle, or by using a slower print mode that will allow you to lower the drying and curing power.
    We recommend setting the custom position to the thickness of the substrate plus 2 to 3 mm for substrates that wrinkle, or plus 1.5 to 2 mm for substrates that do not wrinkle.
  • The normal position is suitable for unwrinkled substrates up to 0.4 mm thick.
  warning:
Keep away from the printer's moving parts until the carriage beam has reached its new position.
  caution:
Do not change the carriage beam position while the printhead cleaning roll is out of place.
