HIGHLIGHT COLOR6-2 XEROX DOCUPRINT 4850/4890 NPS SYSTEM OVERVIEW GUIDEHow to convert full color to highlight colorBecause many documents submitted to DocuPrint NPS support fullcolor, you may try to print a document that specifies colors that ahighlight color DocuPrint NPS cannot print. When DocuPrint receivesa full-color document, the Printer Controller software matches thecolors as closely as possible to a color DocuPrint can print. Thismatching process is not a precise means of specifying color in yourdocuments.To control color conversion in your document, you can use the mapcolor option to specify which color in a full color document you wantto print, using the available highlight color. Colors you do not specifyin the map color option print as shades of gray.You can make the map color differ from the highlight color so redparts of a document are printed as green, or blue portions are printedas red, and so forth.The highlight color rendering algorithm enables you to specify thequalities of a document that are the most important to preserve. Thehighlight rendering attributes allow you to distinguish betweendifferent colors, to use preset color tables, and to apply pictorialmapping for pictures and presentation mapping for other objects.Note: To determine the RGB values of a given highlight color, usethe List Options command. When using the Pictorial highlight colorrendering algorithm, the RGB value given will saturate on the page.When using the presentation algorithm, the RGB value will not besaturated.Color substitutionIf the print document calls for a color that requires a dry ink that is notinstalled in the printer, the Printer Controller acts according to thecurrent color substitution parameters.There are three options for color substitution with the color mismatchaction:• Abort—Deletes the job.• UseLoadedColor—Uses the toner that is currently loaded onthe printer.• RequestOperatorIntervention—Causes a job to be ineligible forprinting until the highlight color is changed.At your client workstation, you can specify these color substitutionoptions when submitting a job to DocuPrint.
