DJ, are you talking laminating photo-etch-resist film to the copper laminate, or something else like photographic or print-on film for artwork? I was asking in general about exposing etching photomask, and imagining using liquid emulsion of some kind, but film photomask like the PCB makers use would be good too... John Griessen PS have you tried laser printer photomask film ,(artwork), such as Kimodesk? _______________________________________________ geda-dev mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-dev
