HP Scitex LX850 and LX820 Printer Series - Substrate tips

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.
  • 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 (or see Tips for specific substrates).
  • Check that the substrate is correctly attached to the input core. Otherwise, you will see poor print quality due to substrate advance errors.
  • You may find it easier to load a roll if you first move the carriage beam to its highest position.
While loading a roll, make sure 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).
After you have loaded a roll:
  • Make sure that the edge holders are set on both sides of the roll. Do not use any other Edge holder from another printer, only use the edge holders that came with the printer. An incorrectly loaded roll may cause waves or cockles in the substrate, leading to ink smearing and printhead crashes.
  • Check the correct carriage beam position for printing: high for thick substrates, normal for others.
  • Check that you are using the correct substrate preset in the HP 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. However, you may want to modify the ink limits or the number of passes; in which case, temperature, vacuum or tensions may need to be adjusted. You can create a new substrate preset from the default preset you are using and make your changes.
  • Use the HP Internal Print Server to check that any required calibrations have been done: color calibration, substrate-advance compensation, printhead alignment.
  • For the best print quality, the substrate should stay flat and unwrinkled in the printing zone, the substrate advance should be constant and the substrate should move straight.
  • Do not cut off pieces of substrate while the substrate is loaded into the printer. This may cause the remaining substrate to jam.
After printing, try to allow 24 hours before stacking, folding or rolling printed substrates.
note:
Printing on porous substrates may result in visible vapor being generated from the water-based ink.

HP Durable Frontlit Scrim Banner
Inside (smooth side)
Use the right settings to avoid printing issues.
HP Outdoor Frontlit Scrim Banner
Inside (smooth side)
Use the right settings to avoid printing issues.
HP HDPE Reinforced Banner
Inside (matte side)
This substrate is sensitive to high temperatures. Printing and curing temperatures are set to minimize material deformation. If the ambient temperature is high and you see excessive deformation of the substrate, raise the carriage beam to its highest position. Recyclable (see above).
HP Permanent Gloss Adhesive Vinyl
Outside (glossy side)
Use the right settings to avoid printing issues.
HP Permanent Matte Adhesive Vinyl
Outside
Use the right settings to avoid printing issues.
HP Air Release Adhesive Gloss Cast Vinyl

HP Wrinkle-free Flag with liner
Outside (fabric side)
Take care to load the substrate and select settings correctly to avoid liner delamination while printing. Recyclable (see above).
HP Heavy Textile Banner
Inside
Recyclable (see above).
HP Light Textile Display Banner
Both sides; inside recommended
You are recommended to clean the platen after printing 50 m of substrate.
HP Blue Black Billboard Paper
Outside (white side)
Use the right settings to avoid printing issues.
HP Photo-realistic Poster Paper
Both sides
This substrate is sensitive to high temperatures. Printing and curing temperatures are set to avoid material deformation.
This substrate is recyclable: you can dispose of it together with cardboard.
