Tektronix 380 사용자 설명서

Tektronix halftone screens are designed for Tektronix printers, and improve 

print quality over application-set halftone screens.  The Setscreen Off 

(SCRENOFF.PS) utility Þle redeÞnes 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 Þles, depending on your computer type, to control 

application-deÞned halftone screens in your prints.         

instructions on installing the utility Þles from the Phaser 380 

printerÕs CD-ROM.

Select the appropriate printer in the Chooser.  

In the PhaserTools folder on your computerÕs hard disk, locate the 

LaserWriter Utility and double-click its icon to start the application.  

From the Utilities menu, choose Download PostScript File.  

Select either the Setscreen On or the Setscreen Off Þle from the list, 

then click Open.  (These Þles were installed in the Printer Utilities 

folder, inside the PhaserTools folder.) 

At the prompt 

Save PostScript output as:

 you are asked 

for a Þle 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 Þle to the printer.

If no output is returned by the printer, the LaserWriter Utility 

displays a dialog box; click OK continue.
