ICR presents a colloquium on
Device Independent Color:
How Possible Is It?
by
Maureen C. Stone
of
Xerox Palo Alto Research Center
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.

I wonder if someone could point me towards interesting 'current research' in the area. I studied this some before (I've read Maureen's articles in SIGGRAPH of - I think - year before last) but I've been unavoidably busy with other things. I'd now like to catch up. Could people help? -john -- John Eadie, Computing Art (FrameMaker) (416) 536-9951 { }!suncan!c-art!jae -OR- { }!sun!jeadie % these deepest problems are in fact *not* problems at all - Wittgenstein
