HP Color LaserJet 3800 Printer series - Manual (Page 115)

The sRGB standard improves your ability to match colors between the printer, the computer monitor,
and other input devices automatically, and eliminates the need to become a color expert.
Printing in four colors (CMYK)
NOTE This feature is available for the HP Color LaserJet 3000 and 3800 Series printers only.
Cyan, magenta, yellow, and black (CMYK) are the inks that a printing press uses in four-color printing.
Graphic arts (printing and publishing) environments typically use CMYK data files to provide rich,
saturated colors for text and graphics. The printer uses the PS printer driver to accept CMYK colors.
CMYK ink-set emulation (PostScript only)
The HP Color LaserJet 3000 and 3800 Series printers use CMYK color rendering to emulate several
standard offset-press ink sets:
● Default CMYK+: This selection is good for general-purpose rendering of CMYK data. It is designed
to render photographs well while providing rich, saturated colors for text and graphics.
● Specifications for Web Offset Publications (SWOP): This selection replicates the common ink
standard in the U.S. and other locations.
● Euroscale: This selection replicates the common ink standard in Europe and other locations.
● Dainippon Ink and Chemical (DIC): This selection replicates the common ink standard in Japan
and other locations.
● Device: This selection turns off emulation. Color must be managed in the software program or
operating system in order to render photographs correctly.
