If printer-specific PANTONE Colors are not printing as expected, make sure that you 
are printing without any color corrections selected.  Refer to “PANTONE® Color 
Files” on page 130 for more information.  

There are many variables in process reproduction of colors generated by your 
printer, any one of which may affect the quality of the PANTONE Color simulation, 
including: 

■

Type of media used

■

Print quality mode selected

■

Effective final resolution

■

Dot structure/halftones 

■

Density of the toner colors

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.         

Refer to “Using the files on the printer’s CD-ROM” on page 135 for instructions on 
using these files.
