About Spotless Extended Color Management
Spotless Extended Color Management expands the functionality of
Prinergy beyond CMYK to allow extended process color sets to
enhance quality and increase the number of spot colors that can be
replaced with process colors.
In Prinergy, spot color recipes are replaced with process color recipes
(also known as color builds) for a specific ink set. On press, spot color
inks are replaced with process color inks, giving spot color
performance on a process color budget.
For example, an extended process color set could consist of six process
colors: cyan, magenta, yellow, black, orange, and green (CMYKOG).
For this process color set, the recipes for all the colors are comprised of
combinations of CMYKOG. You store the color recipes in the Color
Editor in Prinergy Workshop and use them to convert spot colors to
process color.
For more information, see the Spotless Extended Color Management
documentation.
Die line and varnishes
About die line and varnish colors
A die is a series of knives used to cut shapes from a press sheet, and a
die line is a line that represents the position of the various knives and is
used to guide the die in cutting a press sheet. Die lines are usually
created using a Computer Assisted Design (CAD) program and
included in the original input files added to Prinergy.
A varnish or overprint coating is created to protect or improve the
visual appeal of a printed page, and is used to protect the print, for
decoration, adhesion, or for resistance to oil or moisture.
Die lines and varnishes need specific opacity attributes to ensure the
file prints correctly. For example, die lines cannot be trapped; they need
to be set to knockout on composite proofs and as an overprint ink
when outputting separations. Varnishes shouldn't display on
composite proofs.
Note: The die line or varnish color must have exactly the same name in Prinergy as
it has in the input file. For example, if the native application file includes the colors
Die and Varn, the color database in Prinergy must include a color Die or Varn.
If a die line or varnish color is not defined in the color database,
Prinergy treats it as a separate spot color and the color may print with
incorrect attributes.
