G-3 Glossary
DCS (Desktop Color Separation)
A data file standard defined by Quark,
Inc., to assist in making color separations
with desktop publishing system; five files
are created, four color files (one each for
C, M, Y, and K) and a composite color
preview file of the color image. It allows
an image-editing application to perform
color separation and pass it through to
final output with its integrity intact.
densitometer
An instrument commonly used in the
