HIGHLIGHT COLOR
6-2 XEROX DOCUPRINT 92C NPS SYSTEM OVERVIEW GUIDE
How to convert full color to highlight color
Because many documents submitted to DocuPrint NPS support full
color, you may try to print a document that specifies colors that a
highlight color DocuPrint NPS cannot print. When DocuPrint receives
a full-color document, the Printer Controller software matches the
colors as closely as possible to a color DocuPrint can print. This
matching process is not a precise means of specifying color in your
documents.
To control color conversion in your document, you can use the map
color option, also called extraction color, to specify which color in a
full color document you want to print, using the available highlight
color. Colors you do not specify in the map color option print as
shades of gray.
You can make the map color differ from the highlight color so red
parts of a document are printed as green, or blue portions are printed
as red, and so forth.
The highlight color rendering algorithm enables you to specify the
qualities of a document that are the most important to preserve. The
highlight rendering attributes allow you to distinguish between
different colors, to use preset color tables, and to apply pictorial
mapping for pictures and presentation mapping for other objects.
Note: To determine the RGB values of a given highlight color, use
the List Options command. When using the Pictorial highlight color
rendering algorithm, the RGB value given will saturate on the page.
When using the presentation algorithm, the RGB value will not be
saturated.
Color substitution
If the print document calls for a color that requires a dry ink that is not
installed in the printer, the Printer Controller acts according to the
current color substitution parameters.
The options for color substitution with the color mismatch action are:
• Abort—Deletes the job.
• UseLoadedColor—Uses the toner that is currently loaded on
the printer.
•
RequestOperatorIntervention—Causes a job to be ineligible for
printing until the highlight color is changed.
At your client workstation, you can specify these color substitution
options when submitting a job to DocuPrint.
