Color selection process
The user selects the color in the application, but the operating system might convert or
modify some characteristics of the color before sending the information to the printer driver.
The printer driver might also modify color characteristics depending upon the selected output
mode.
Any color characteristics not addressed by the printer driver or applications are set to the
printer default. The default color might not match the color the user selected.
Matching colors
The user can match colors using Pantone® color matching systems or swatch book color
matching.
PANTONE®* color matching
PANTONE®* has multiple color matching systems. PANTONE®* Matching System is very
popular and uses solid inks to generate a wide range of color hues and tints. See
http://www.hp.com for details on how to use PANTONE®* Matching System with this printer.
Swatch book color matching
The process for matching printer output to preprinted swatch books and standard color
references is complex. In general, you can obtain a reasonably good match to a swatch
book if the inks used to create the swatch book are cyan, magenta, yellow, and black. These
are usually referred to as process color swatch books.
Some swatch books are created from spot colors. Spot colors are specially created
colorants. Many of these spot colors are outside of the gamut of the printer. Most spot color
swatch books have companion process swatch books that provide CMYK approximations to
the spot color.
Most process swatch books will have a note on what process standards were used to print
the swatch book. In most cases they will be SWOP, EURO, or DIC. To get optimal color
matching to the process swatch book, select the corresponding ink emulation from the
printer menu. If you cannot identify the process standard, use SWOP ink emulation.
