Paper selection

sRGB
Standard red-green-blue (sRGB) is a worldwide color standard originally developed by HP and Microsoft
as a common color language for monitors, input devices (scanners, digital cameras), and output devices
(products, 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.
The latest versions of Adobe PhotoShop, CorelDRAW™, Microsoft Office, and many other software
programs 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
software programs 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 product, the
computer monitor, and other input devices (scanner, digital camera) automatically, without the need to
become a color expert.
Print 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 product will accept CMYK colors through the PS printer driver. The
product color-rendering of CMYK is designed to provide rich, saturated colors for text and graphics.
CMYK ink set emulation (HP postscript level 3 emulation)
The product color rendering of CMYK can be made to emulate several standard offset press ink sets.
In some situations, the CMYK color values in an image or document might not be suited to the product.
For example, a document might be optimized for another product. For best results, the CMYK values
