Hello,
There have been quite a few queries about my prevous mail so I
thought of mailing some details to the group.
1. It is SciTek 3130. There could be other high resolution printers which
are routinely used by Offset printers in Bombay who cater to ad ajencies
to provide images in print.
2. Bromides is an option. You can decide positive or negative while
firing. The postscript file can be used to get either output.
3. If you specify SCREEN PRINTING then emulsion is down.
If you specify OFFSET PRINTING then emulsion is up.
4. The film is TRANSPARENT to uv and the printed lines are NOT. We've
directly used it for lithography and got good results.
Hope this info is useful.
Regards,
-Ashutosh-
