Solved:transparency masks

[Jing Xia]

Thanks for the detailed instructions from Adam E.Cohen,
Farhat Quli, Casey Feinstein, Robby Feller and Neiville Mehenti.

It seems that the easiest method is tape the transparency to a blank plate
and then do the exposure in Kalsuss or other aligners. The exposure time may
need to be increased by 50% due to the fact that mylar absorbs significantly
more light than quartz.

Thanks again for your help and have a great weekend!
