Then place this paper on a film in a dark room and expose it to strong light for 1 second, Something puzzles me... If I've understood you correctly...You make negative A4, then conctact copy it to positive film and then make uv exposure to photo-sensitive PCB. Right? My question is - what's the catch? Don't you have degradation in quality by twice exposure process? If you have questionable laser copy in the first place don't you reproduce its problems on film in the same manner you would to photo-sensitive PCB? I'm not familiar with this blue transparency you mention. Can you give some more details about it. Best luck, CN |
