Look at the link Tom posted: http://www.phototypie.net Even with failed high school French from half a century ago I figured out a lot by going through the long set of photos and discription on the site. My question, is why do they use glass? A less fragile sub would seem a lot less trouble. Is there something about glass that creates a better bond or do they flash it from the back to help bond it? It seems that a metal plate could be grained the same way just as zinc plates are for lithography. Jack
