Phaser 560 Color Laser Printer

Printing PANTONE Colors

If Phaser 560 printer-specific PANTONE Colors are not printing as expected,
make sure that you are printing without any color corrections selected.
Refer to “Printing and using the color sampler charts” on page 5-25 for more
information.

If you have questions about PANTONE Color Matching, refer to the HAL
article on PANTONE Colors. Refer to page 7-3 for information on using the
HAL and EuroHAL fax systems.

There are many variables in process reproduction of colors generated by the
Phaser 560 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.

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.
