Using the Tektronix halftone screens
Tektronix halftone screens are designed for Tektronix printers, and improve print
quality over application-set halftone screens. The

Setscreen Off (SCRENOFF.PS)

utility file redefines some PostScript operators, such as the

setscreen

,

setcolorscreen

and

sethalftone

. When downloaded to the printer, this file prevents
applications from overriding the Tektronix proprietary halftone screens.
