[comp.lang.postscript] Screened Images on Postscript?

douglasg@hpgrla.HP.COM (@Douglas Genetten) (03/03/88)

	What are the halftone screen generating capabilities of Postcript?
	Is it limited to spot color (tints, gradations) or can it do
	halftones of scanned photographic images?  

	If so, can it do any kind of color correction and dot gain compensation?

	Thanks.
