Please do. I see Photoshop as a logical tool for most alternative
processes. For example, I am anticipating a project involving trying
to produce randomly screened negatives and positives (of various dpi)
in photoshop for 3-color printing in different processes. My
experiments so far make me feel that photoshop is the right track, but
I have lots of questions that the manual doesn't cover.

I have a 1200 dpi modified HP Laserjet (which isn't that expensive.)
The output is near typeset quality for letterforms and graphics, but
halftones come out the equivalent of about a 133 line screen (standard
magazine quality). By conparison, 300 dpi printers can output a roughly
70-80 line screen (newspaper quality). For some processes this might be
OK, but it won't fool the eye into mistaking it for continuous tone.
