I know about the green trick, but I haven't used it for three reasons: 1. My undithered black blocks enough UV already. 2. The alignment between the two colors isn't as good as I'd hoped. 3. I can replace the black ink for less money than the CMY ink. > I'm fully happy with it. The mask is really UV opaque, exposure time > can be increase a lot compared to plain black. I have a Stouffer transmission step gauge and my UV box has a lab-grade timer on it. The film I use says what the exposure *should* be. More is not better with these. Even with just black, I'm able to use the recommended exposure and still block enough UV to leave a big margin of error. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
