XEROX DOCUPRINT 4850/4890 NPS SYSTEM OVERVIEW GUIDE 6-16. 6Highlight colorThis chapter explains the concept of highlight color, and describesthe process for specifying and applying highlight color to a document,matching monitor and printer colors, and converting full process colorjobs for printing on a highlight color printer.How highlight color is createdA document with highlight color contains one color plus black. Thecolor may be printed either as a solid color or combined with black.To create tints and shades, the DocuPrint highlight color printers printdots of black and dots of color very close together. The dots mixvisually to produce a wide range of color. DocuPrint prints the blackand color dots in a single pass, ensuring near-perfect registration.• Tints of black or the highlight color are created by printing dotsof black or color with white space between them, producing apercentage value of the color, for example, gray or pink.• Shades are created by printing black dots next to dots of thehighlight color, producing, for example, a dark red.• Tones are created by printing a combination of black dots, colordots, and blank space. The result is a percentage value of blackand the highlight color such as a dark red made by mixing dotsof red and black, or a gray-pink made by mixing dots of red andblack dots with some blank space as well.These patterns of dots are known as halftone screens. Screens aredefined in the Printer Controller software as a matrix of bits, whichcorrespond to printed dots. The screen defines which dots in thematrix are black, which are highlight color, and which are not printed.How highlight color is specifiedYou specify color in application software. The DocuPrint provideshighlight color toner in a selection of colors: red, ruby, cardinal, blue,royal blue, green, cyan, magenta, violet, and brown.If you specify a color in your document that DocuPrint cannot print, itis printed either as a shade of gray or as an equivalent tone of thehighlight color installed in the printer at the time.For more information on this matching process, see “How to convertfull color to highlight color.”
