Re: tip for ink jet neg substrates

I had some time this weekend and printed a few diginegs on my 2200 using
Photo warehouse film. Incidently my box of transparency came with a white
strip. I printed a gum negative with a black ink only at 1440 dpi. To my
surprise the ink did not smear, there were no roller marks on it as well.
The negative looked somewhat grainy, but it might not matter for gum (even
less for multiple gums). I did not print anything using this negative. It
was just a printer test. It seems that the ultfafine transparency film can
handle some ink, but much less then OHP. This is most likely related to
the thickness of the coating layer.
Thinner coating might be sufficient for thinner negatives. After that, I
printed a thinner negative on the same transparency film using all inks
and noticed that it was slightly easier to smear then the back, but could
be handled quite well.
My original failed attempt to use ultrafine transparency film was to
print Pd negatives, which were quite dense resulting in lots of ink on the
I am actually encouraged to try it for 4 color gum separations.
