Colors are printing incorrectly

Tektronix halftone screens are designed for Tektronix printers, and improve print quality over application-set halftone screens. The Setscreen Patch utility file redefines the setscreen, setcolorscreen and sethalftone PostScript operators. When downloaded to the printer, this file prevents applications from overriding the Tektronix proprietary halftone screens.

Use the utility files for your computer type.
