Xerox DocuColor 12 Printer with Fiery EX12 Fascicule

A system of named color swatches that 
can be matched on press using process or 
spot colors. PANTONE and TruMatch 
are examples of custom color systems.

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.

An instrument commonly used in the 
graphic arts industry to measure density 
according to a specified standard. 

A measurement of the light-absorbing 
quality of a photographic or printed 
image.

See DCS.

A Japanese standard of specifications for 
separations, proofs, and color printing. 

A PostScript file format designed to be 
embedded in another PostScript stream.

A European standard of specifications 
for separations, proofs, and color

A printing technology that uses flexible 
raised-image plates. Flexography can be 
used to print on non-flat materials such 
as cans.

A printing device that uses cyan, 
magenta, yellow, and black ink or toner.

A numeric value representing the 
relationship (gamma curve) between the 
input and output values of a color 
device. If gamma equals 1, input values 
are mapped exactly to output values.

A range of colors. A device gamut is the 
range of colors that a device, such as a 
copier/printer, can produce. An image 
gamut is the range of colors in a 
particular image.

The conversion of color coordinates 
from one device’s gamut to another—
usually accomplished with algorithms or 
look-up tables.
