HP Color LaserJet 8500 and 8550 Printers - How to Optimize Color Output

Controlling Color Output with Printer Drivers
By varying the amount and pattern of the four toner colors applied to a page, and in combination with halftoning, the printer can produce more than 16 million colors. Use the printer drivers (the software installed with the printer) to control the color output for text, graphics, and photographs. The printer drivers enable computer applications to communicate with the printer and to use all of its features. Access to the printer drivers depends on the computer system. For example, in a system using Microsoft (R) Windows, use the application’s Print Setup command to access your printer driver. For specific instructions on accessing the printer driver, see the online help files for your operating system.
  note:
Applications override most printer settings, such as media size, copies, and media source. When possible, use application settings for adjustments.

HP ColorSmart II Utility
HP ColorSmart II technology optimizes the color and halftoning for each element in a document (such as text, graphics, and photographs).
  • The HP ColorSmart II utility uses the Screen Match setting to reproduce all elements in a document. The Screen Match setting uses a smooth halftone for photographs or image data and detail halftone for all other types of image data on the page including text. This setting provides consistent color treatment for everything on a page.
  • When Transparency is selected in the Paper tab of the printer driver, the HP ColorSmart II utility chooses specialized colors to provide the best projection quality.
  • The HP ColorSmart II utility is also the most reliable setting for PANTONE (R)* color reproduction. For more information on using PANTONE (R)* colors, see “PANTONE (R)* Colors” later in this chapter.
Manual Mode
For custom color printing jobs, you can turn off HP ColorSmart II defaults and set color adjustments manually. The Manual mode allows you to adjust the color settings for text, graphics, and photographs separately by manipulating the available settings. The following settings apply to all types of media:
  • Halftone - Changes the method used to produce lighter shades of solid colors.
    • Smooth - Works well for solid areas, gradients, and photographs by smoothing out fine color gradations and providing accurate color reproduction.
    • Detail - Works well for text, multiple-colored text, line art, and detail-oriented graphics by providing sharper edges.
  • Color Adjustment—Changes the color settings for all elements on the page.
    • Screen Match - Color is optimized for reproducing of sRGB monitor colors. (The term sRGB is generally used to define RGB, red/green/blue, color output for monitors.) This setting maximizes the similarities between the appearance of the printed document and the document as it appears on the monitor. Screen Match is the printer default input color source.
    • Vivid - Saturation of colors is enhanced to produce high-impact color appearance.
    • OHT - (Overhead Transparency) For optimized color quality for projection anytime Transparency is selected on the Paper tab in the printer driver.
All settings in the printer driver will remain in effect until they are changed. The online help describes in more detail the printer color settings and options, and their effect on your output.
ICC/CMS
Some applications and operating systems support more specific color management systems (CMS):
  • ICC (International Color Consortium) is an international standard for color profiles that describe the color characteristics of devices, such as printers.
  • ColorSync 2.x is Macintosh’s color management system for System 7.
For information on downloading and selecting color profiles, see the online help. If you are generating customized color profiles, use the same printer driver settings for both generating the profiles and printing.
Visit http://www.hp.com/go/clj8500_software orhttp://www.hp.com/go/clj8550_software to download available ICC (CMYK or sRGB) profiles from the HP Web site.
Black and White
Selecting Black and White in the Color tab allows your color documents to be printed as black and white documents with shades of gray. This setting allows you to view preliminary copies of slides and hard copy output quickly and still interpret your color information. Printing in black and white also works well for color information that you wish to photocopy or fax.
Adjusting the Print Color and Quality Settings
For most color printing needs, HP ColorSmart II default settings will handle your color adjustments. For some print jobs, you might want to turn off HP ColorSmart II defaults and set color controls manually. The following table shows default color settings in the printer driver and recommended printer driver settings for various types of printed output:

Selecting colors
The computer and printer use different color processing methods. Other factors, such as print media and lighting, also influence and limit your ability to match colors from the screen to your output. In addition to the printer driver color controls described in this chapter and the media you choose for printing, the following tools can help you to match the screen display and color output.
PANTONE (R)* colors
PANTONE (R)* colors are certified CMYK (cyan, magenta, yellow, and black) and sRGB color values in the PANTONE (R)* color matching system. This option affects your output only if your application supports PANTONE (R)* colors. See the application’s instructions for using these colors. The color and halftone settings and the media you use will affect the appearance of printed PANTONE (R)* colors. For the best PANTONE (R)* color reproduction, set the printer driver to ColorSmart II or make the selections shown in the table in “Adjusting Print Color and Quality Settings” on the previous page. Or, if you are using the Manual setting, select Screen Match for the most accurate color reproduction. The device profiles for PANTONE (R)* Maps are created using the Screen Match setting; select this setting for best results. For more information on printer driver settings, see the online help or the readme file.
Visit http://www.hp.com/go/clj8500_software orhttp://www.hp.com/go/clj8550_software to download available Pantone Color Pallettes from the HP Web site.
Color Palette Samples
With HP ColorSmart II selected, the color palette samples program will send several pages of example colors and their accompanying RGB and CMYK values to the printer. These pages are useful for selecting or matching colors in applications that allow you to specify RGB or CMYK color values. If you are using the sRGB values, select ColorSmart II on the Color tab in the printer driver. For information on using the color palette samples utility, see the associated readme file.
Resolution Considerations for Graphics
Images and photographs can come from many different sources such as digital cameras, scanners, and photograph CD-ROMs. Typical file extensions for images and photographs are .bmp, .fpx, .gif, .jpg, .png, and .tif. For these images, resolution decisions should be made based on the content of the image. When possible, import images at the size you plan to use (actual size).
  • Graphics and line art should be imported at the maximum resolution, preferably 600 dpi (the printer’s maximum resolution). For best reproduction of raster images, the printer driver halftone settings should be set to Detail.
  • Images should be at least 200 dpi, and preferably 300 dpi. The printer driver settings should be set to ColorSmart II or Manual, with an image setting of Smooth and a color setting of Screen Match.
      note:
    Resolutions of higher than 300 dpi will produce significantly larger files, but the print quality of the image will not necessarily improve.
Using digital cameras
When printing images captured by a digital camera, you might have to adjust the image quality. Adjust the images with the imaging software that came with the digital camera. Generally, for the most accurate color rendering, leave the digital image color mode in RGB. When you print the image, the printer will convert the RGB information to CMYK. For more information on adjusting the image quality of digital photographs, see the imaging software documentation. For photographs, use ColorSmart II setting in the Color tab. Or, if you are using the Manual setting, select Smooth Halftone and Screen Match color mode. For more information on printer driver settings, see the online help.
Using scanners
For the best image quality, make as many adjustments as possible in the scanner imaging software before scanning. These adjustments, many of which are listed below, can increase the resolution of the image, resulting in higher quality images:
  • Select the appropriate image type (for example, color photograph, line art, or text).
  • Select the optimum image resolution based on image type, at least 300 dpi for most images; however, select 600 dpi for line art, graphics, and text.
  • Crop the image to scan only what you need. Scale the image for the optimum resolution when it is reproduced.
  • Adjust the image sharpness, contrast, and brightness.
  • Set the gamma correction to 2.2. For more information on scanner gamma correction, see the scanner’s documentation.
  • When possible, import images at the size you plan to use (actual size).
Adjusting the color balance
  caution:
Adjusting the color balance will change the printer’s calibration by altering toner bias and laser power.
Because this procedure adjusts parameters within the printer hardware, it will affect all print jobs. Check with your system administrator before making any changes to the color balance. The printer automatically recalibrates the color settings. However, you can adjust the color manually by changing the densities of the four toners (black, cyan, magenta, and yellow). The Detail Halftone Adjust and Smooth Halftone Adjust allow you to independently adjust the color of objects on a page (such as text and graphics). Do not perform the color balance adjustment procedure until all of the following troubleshooting methods have been completed:
  • Experiment with the printer driver and application settings to adjust the color output. For more information on application settings, see the previous sections on printer driver settings in this chapter or the online help.
  • Clean the density sensor in the printer. For more information, see “Cleaning the Density Sensor” in chapter 9.
  • Complete the troubleshooting solutions in chapter 9 of your user's guide for the color printing problem you are experiencing.
