ICR presents a colloquium on
Device Independent Color:
How Possible Is It?

Abstract
Color producing digital devices such as monitors, printers, film
and video recorders are becoming common in digital systems. These
devices are deceptively simple--put bits into one end and colors
come out the other. However, putting the same bits into two dif-
ferent color devices rarely produces the same visual results.
Traditionally, application communities have used either the addi-
tive (red, green, blue) or subtractive (cyan, magenta, yellow)
primaries to represent color. Now, however, it is not unusual to
have both additive (monitors) and subtractive (printers) equip-
ment available on the same system. A "device independent"
description for color would make it possible to use a single
representation across all system devices. This laudable goal is
quite difficult because such a representation must consider many
complex issues of human color perception as well as the differ-
ence between additive and subtractive color systems. This talk
will describe some current research in this area, with an em-
phasis on the problem of transferring images designed on a moni-
tor to the printed page.
