Digital BW, The Print

Mark,  Didn't see that this was going on in two groups. Kept looking for my
post in the other one. : (  Yes, a static change is on plexi so laying a
plastic print like a ciba over a charged sheet of plastic stuck. If the
plexi is cleaned and polished, on the outside is it possible that a charge
is acting on the image/paper mix? Wooden or metal frame? Complex set of
interaction to be sure. Do you have any photos of the offending areas? 
 
Since it is showing up in areas that have no glue, it must be a stress
related or surface related issue. The marks in the paper do not show up in
the bottom of the image where it is free to move. Long term effects of D
roller? I have a large vacuum heat press that I use to flatten images, but I
haven't gone that big. 50" max.

I know that Jon is not a fan of Photo Rag and has in the past not
recommended it for Piezotones but I have been using it for years with no
issues. Again I need to stress that this same issue is also happening in
areas were there is no glue on the back of the print, almost dead center of
the image. So I want to rule out the glue. Over the next few months I am
going to reprint it and will have access to the problem print and will
probably sent it to Hahnemuhle to see what they say.

Mine were printed with Piezo Black, also on Photo Rag paper.
