Phaser 350 Color Printer
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. By default, the printer prevents
applications from overriding the Tektronix proprietary halftone screens.
Use the following utility files, depending on your computer type, to control
application-defined halftone screens in your prints.
Macintosh users
1. Refer to “Using the Macintosh Installer” on page 2-53 for
instructions on installing the utility files from the Phaser 350
printer’s CD-ROM.
2. Select the appropriate printer in the Chooser.
3. Locate the LaserWriter Utility in the PhaserTools folder on your hard
disk, and double-click its icon to start the application.
4. Choose Download PostScript File from the Utilities menu.
5. Select either the Setscreen On or the Setscreen Off file from the list,
then click Open. (These files were installed in the Printer Utilities
folder, inside the PhaserTools folder.)
6. At the prompt Save PostScript output as: you are asked
for a file name for saving printer output. Use either the default
name given in the edit box or type a new name. Click Save to
send the file to the printer.
7. If no output is returned by the printer, the LaserWriter Utility
displays a dialog box; click OK continue.
