For UV mask production, definitely not - I used a cheap cartridge in my=20 HP laser jet and it was a lot worse than the HP cartridge (basically not=20 as black/sharp so UV passed through where it shouldn't) For direct transfer to PCB (which I think is what you are more=20 interested in) If I recall correctly (though it was ages ago when I=20 looked into this) it's only laserjet ink (not inkjet) that works as a=20 resist due to the plastic content or something, and quality varies with=20 different inks (though I don't think by too much) I'm sure folk who produce PCBs that way will have some better info on=20 the direct method though. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
