I would like to create photomasks from a PC printer (either inkjet or laser)
and appropriate transparent media. I need a resolution on the order of .001
inch (25 micrometers).

I have seen on the web a mix of products and technology articles, but none are
clear on a working combination of printer (type or model), required printer
resolution (DPI), ink, and transparency media. I've seen comments that even
1200 dpi resolution is not adequate to produce a continuous "black" mask of
sufficient density to adequately block the UV used in the photoresist exposure.

Can you suggest a printer, ink and transparency media that has worked for you,
or direct me to a source for that information?

Thank you.
