PostScript applications
should use swatch color matching to ensure predictable color printing results with the
DocuColor 40 CP or to match your DocuColor 40 CP color output to colors
produced by other print devices.
Swatch color matching
Your DocuColor 40 CP user software includes downloadable PostScript files of
reference pages for CMYK colors and PANTONE-equivalent colors. By choosing
colors from these reference pages, you can be sure of obtaining the same color from
your print device.
For best results, calibrate the DocuColor 40 CP before printing the reference pages
and your final output.

Swatch color matching does not match monitor colors to printed colors. For this
you must use a color management system and calibrate your monitor to the color
output of your print device.
Using the CMYK color reference pages
The CMYK color reference pages, included with your DocuColor 40 CP user
software, let you see how various cyan, magenta, yellow, and black combinations look
when printed on your print device. Using the CMYK color reference pages, you can
easily determine the CMYK values to specify to obtain the printed colors you want.
The CMYK color reference file is a PostScript file that prints 11 letter/A4-size pages.
To use the CMYK color reference pages, download the file using DocuColor
Downloader. The printed pages display groups of color patches in graduated
combinations of yellow, magenta, and cyan, and smaller patches that include 25, 50,
and 75% black. Refer to these pages to pick colors and specify process color values in
your application. (For the location of the CMYK color reference file, see Getting
Started. For instructions on using DocuColor Downloader, see the Printing Guide.)

If you plan to later print your document on press, you may need to adjust the
process values to duplicate the colors from your DocuColor 40 CP.
