sRGB

Standard red-green-blue (sRGB) is a world-wide color standard originally developed by HP
and Microsoft as a common color language for monitors, input devices (scanners, digital
cameras), and output devices (printers, plotters). It is the default color space used for HP
products, Microsoft operating systems, the Web, and most office software sold today. sRGB
is representative of the typical Windows computer monitor today and the convergence
standard for high-definition television.

Note

Factors such as the type of monitor you use and the room’s lighting can affect the
appearance of colors on your screen. For more information, see

Matching colors

.

The latest versions of Adobe PhotoShop, CorelDRAW™, Microsoft Office, and many other
applications use sRGB to communicate color. Most importantly, as the default color space in
Microsoft operating systems, sRGB has gained broad adoption as a means to exchange
color information between applications and devices using a common definition that assures
typical users will experience greatly improved color matching. sRGB improves your ability to
match colors between the printer, the computer monitor and other input devices (scanner,
digital camera) automatically, without the need to become a color expert.

Printing in four colors — CMYK

Cyan, magenta, yellow, and black (CMYK) are the inks used by a printing press. The
process is often called four-color printing. CMYK data files are typically used by and
originate from graphic arts (printing and publishing) environments. The printer will accept
CMYK colors through the PS printer driver. The printer color-rendering of CMYK is designed
to provide rich, saturated colors for text and graphics.

CMYK ink set emulation (PostScript only)

The printer’s color rendering of CMYK can be made to emulate several standard Offset
Press ink sets.

Default. This selection is good for general purpose rendering of CMYK data. It is
designed to render photographs well, while at the same time providing rich saturated
colors for text and graphics.

Specification for Web Offset Publications (SWOP). Common ink standards in
the United States and other locations.

Euroscale. Common ink standard for Europe and other locations.

Dainippon Ink and Chemical (DIC). Common ink standard in Japan and other locations.

Device. Emulation is turned off. To render photographs properly with this selection,
images require color management in the application or operating system.
