Re: photopolymer

Hi Keith,

Thanks for the feedback on the screens.  Wish getting finer screens that 
were thick, consistent and durable were as easy as a phone call to 
someone like Elizabeth Dove.  Wonder if she'd do custom screens for me 
(without taking me to the cleaners in the process)! 
ImagOn is fun stuff but it is much more of a challenge to get smooth 
continuous tone using it.  It also breaks down after 5 prints or 
so...much quicker than polymer.  Of course polymer breaks down much MUCH 
quicker than copper...and so it goes.

Kreene eliminated the surface newton rings/dots I was getting with glass 
on my vacuum frame. It's also be amazing to feel debris through the 
plastic prior to exposing.  Probably saved me dozens of wasted plates 
due to Q/C issues over the past year or two I've been using it. . 
Contact problems around the edge of plate which you describe in your 
earlier email I've not seen before with a vacuum frame.  You say it just 
started since switching plates, but didn't happen before?
