Re: photopolymer
Jon and all, I'm now using Kreene under the glass of the vacuum bed, and I've noticed my prints seem to have a little bit of lower contrast because of it. I haven't tested this out, and likely won't have time to for quite a while. It's not at all a big difference... just thought I'd mention it though. Of course a good PDN curve takes care of it. In fact, I burned dinner the other night, and just whipped up a PDN curve and applied it to my family, and they loved dinner... thought it was perfect all crunchy-like.

I've actually removed the glass entirely from my contact frame and just have Kreene stretched across it. I thought of trying taping it across the glass, but Harold at Box Car seemed to feel the added effect of the glass + kreene wouldn't be as crisp...or something. In any case, I'm happy with the way it's been working, though removing the glass was a little intimidating at the time. Also, I was wondering what image/screen/wattage you're using for exposures just out of curiosity... Thanks!
