Would a PVA size improve the "tooth" of a paper ?. I have this big batch of Van Gelder Simili Japon paper which I use for Pt printing, but that paper is quite smooth an does not work very well with gum.



Btw this paper has to be pre-shrunk, even with 4*5 negatives I have great difficulties aligning gum over Pt prints..
