Color substitution

System overview

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.
