System overview
1-8 System Overview Guide
When the NPS/IPS receives a full-color document, the printer
software matches the colors as closely as possible. If you specify
a color in your document that the NPS/IPS cannot print, it is
printed either as a shade of gray or as an equivalent tone of
highlight color.
To control color conversion in your document, you can use the
map color option, also called “extraction color.” The map color
option is used to specify which color in the full color document
you want to print using the 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 that
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, use preset color tables,
apply pictorial mapping for pictures, and apply presentation
mapping for other objects.
NOTE: To determine the RGB values of a specified highlight
color, view the system options. When the Pictorial highlight color
rendering algorithm is used, the specified RGB value saturates
on the page. When the presentation algorithm is used, the RGB
value does not saturate on the page.
Color substitution
If the print document calls for a color 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 dry ink that is currently loaded
on the printer.
• RequestOperatorIntervention: Causes a job to be
ineligible for printing until the highlight color is changed.
You can specify these color substitution options at a client
workstation when submitting a job to the printer, or by specifying
the HightlightColorMismatchAction attribute in a virtual printer.
