Pretty much. An ink-less page results in 100% UV cure, no developing waste, no etching... if you scrape off the mask partway through stripping you can preserve that solution too. So it behooves me to drop a big rectangle over the signal layers just to save the environment ;-) _______________________________________________ geda-dev mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-dev
