hi Marek,

My apologies for misunderstanding. I have no doubt one can use color inkjet
effectively...all one has to do is look at the faux pyro school of inkjet neg
printing. I prefer believing my eyes and brain (wetware) over my software and
hardware, however, at least at this stage in my work.

My sense is that palladium is going to produce different results than polymer
plates, in any case. For one thing, I'm using a continuous tone screen to
presensitize the plate so it holds ink better. For another, poly plates respond
to a slightly different part of the UV spectrum than palladium. The results I
got from trying color vs. black only pigments were disparate enough for me.

Film seems different enough from inkjet to try (at least for $36), but maybe
it's folly as far as the poly plates go.

Anyone out there print polymer plates using color transparencies?
