Hi Berto,
I use artwork generated from gEDA (on Linux), which I then import as a
Postscript file into Inkscape to tweak the color of the negative gEDA
puts out and the dimensions of the filled area. I'm experimenting
with some new transparency material from this place:
http://www.westixonline.com/water-proof-inkjet-film-for-screen-printers.html It's billed as waterproof which I take to mean it dries instantly,
which it does seem to do. You get 100 sheets for about $45, which is
a lot better than some places. The last film I ordered was not
waterproof and took quite of while with gentle heat to avoid smearing.
I use an Epson Artison 810 which is brain-damaged in that it will not
accept transparency material without a backing sheet of normal paper.
Other than that it does a great job at 5760x2880 (I believe), printing
red (Magenta+Yellow) MISPro ink which does a wonderful job of giving a
very even, solid coverage to filled areas without pooling. Minimum
feature size is somewhere around 8/8, although if you collaminated
your light source better than mine you could probably do better. It's
certainly not a limitation of the printer or the dry film which is
great, properly laminated.
Regards,
Larry
