Notes

Gamma correction is automatically adjusted when printer

 

resolution is changed, and it applies only to PostScript images.

 

If turning on gamma correction doesn’t yield a suitable gray-

 

scale image for your needs, set a specific gamma correction

 

value through your drawing application or through the

 

PostScript settransfer operator. (See your drawing application

 

documentation and the PostScript Language Reference

 

Manual for more information.)

This option allows you to specify the halftone used to print PostScript files. For more information, see chapter 5, “Additional Technical Infor- mation,” in the Reference.
