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.)
