recipes that are specific to the final printing condition (device, media,
inks, and so on).
For example, in composite PostScript or PDF files, override inconsistent
color recipes in a job with a standard recipe so a spot color can be
converted to process or simulated on a proof in the same way
throughout a job.
You can also use the Color Editor to store ink parameters necessary for
trapping. When trapping, the trapper looks to the color definition
(found according to the library search order specified in the refine
process template) for a color's opacity and neutral density values. If
the color is not found, the Trapper assumes an opacity value of Normal
and determines the neutral density value from the CMYK values in the
input file.
Color libraries and alternate color spaces
Color definitions are grouped into libraries. Each color library is
associated with an alternate color space. Each alternate color space
(ACS) is associated with an ICC profile, which is used to populate the
list of colorants. We recommend that you name color libraries
according to the associated ICC profile.
The Color Editor uses the following types of color libraries:
●
Factory libraries
—are populated from named spot color systems—
for example, PANTONE. Factory libraries are preloaded into
Prinergy, and are available to all jobs.
●
User libraries
—are libraries that you populate
○
Global
tab—contains color definitions that are available to all
jobs in the system.
○
Job
tab—contains color definitions that are available only to the
job for which they are defined. Job-specific color definitions
override global color definitions of the same name.
Important: When you remove a user library, all color definitions in its global and
job-specific libraries will be deleted. You will be prompted to confirm.
Within a user library, you can copy colors between the
Global
tab and
the
Job
tab. By copying a color to the
Global
tab, you make the color
available to all jobs. By copying a color to the
Job
tab, you can
customize the color definition for the job without affecting the color
definition for other jobs.
You cannot copy colors between user libraries. But you can import and
export user libraries between Prinergy systems.
