| sRGB is a standard promoted primarily
by Hewlett-Packard and Microsoft. It reflects the standards for
HDTV broadcast (Gamma=2.2, Primaries=HDTV, White Point=6500K).
One of the reasons to use sRGB is that Hewlett-Packard is promoting
a workflow in which hardware devices such as scanners, non-PostScript
printers, and Web browsers will be optimized for RGB data in the
sRGB space. If you are using such devices, sRGB will provide the
simplest workflow.
sRGB reflects the characteristics of the average PC monitor.
If you are producing graphics to be viewed on the Web, sRGB will
reflect what most viewers see. The downside to sRGB is that it
has a limited color gamut and cannot represent as many colors
as other color spaces. It is not a good choice for professional
prepress users since too much of the CMYK gamut lies outside of
it.
