Letterpress printer Jamie of Don’t Press Me has posted a great tutorial on making your own photopolymer plates, with a helpful tip you probably have not seen anywhere else.
As you can see in the photo above, the negative and the about-to-be-exposed photopolymer plate are held together by plastic, in this case the plastic of a Food Saver.
I posted a similar idea in this post, but I hadn’t tried it.
See the complete tutorial here.
