We used aluminized mylar tape for masking negatives and transparencies. Is there a difference in transmission between UV and visible light that might lead to less exposure with UV? Seems counterintuitive with the higher energy though.

Don't know who this paul guy is, but its on the Epson spec page. pl = picoliter

I've got all these and the larger 3.5pl head epsons and it certainly makes a difference.

Bob,
I am not suggesting the use of paper negatives. All of the people I know who are making digital negatives for silver printing are using Picorico or Fixxon OHP.
When one creates perfectly linearized QTR profile for a specific process it should be possible to make a print in silver with a full range of tones from highest highlights to darkest shadows, if you have those tones in the image file. Of course, your exposure also must be spot on, if too long you will print through the shadow densities of the negative and get some bleeding into the highlights. Everyone has this issue in printing with perfectly calibrated negatives so yes, a border that like rubylith or red lithographers tape that add blocking density is necessary to keep clean borders. And sometimes with very long ES processes like albumen or salted paper, you may even have to use two layers of ruby light.
Now, if your process is low ES, say 1.0 -1.5, you could probably get by just by a white border on the positive image file, which will print black on the negative.I usually add that type of canvas, and then use a strip of lighographers tape.
