Printer Color Mixing

Some printers, such as the IBM® 5182, compose certain colors by mixing colors. Colors are mixed by printing the text in one color and then printing over the same text in another color on a second pass.

PC/3270 will compose a color if the color is not defined in the printer definition table of a color printer that is capable of mixing colors. Therefore, if you are using a printer that composes some colors by mixing two colors, leave the definition of the composed colors blank in the printer definition file. Only the composite colors defined in Table 1 are created by double-printing the primary colors.

Table 1. Color Mixes
Composite Color Primary Colors
Red yellow, magenta
Green yellow, cyan
Blue magenta, cyan

For example, to create red, you must define yellow and magenta. The primary colors must be defined in the printer definition table.
