Re: Photopolymer Plate Options
Hi Mark, The "EcoEtch" plate from Box Car Press I mentioned is the Toyobo (model KM73) plate. "EcoEtch for Photogravure" is their internal name for it at Box Car Press. I believe it is the same plate Keith was talking about too. We discussed different sources for the plate, Box Car Press being the most affordable I've found. I've read references to other Toyobo plates here too, but I'm not sure what they are about or how they differ from the KM73. That plate has come recommended by several people on this list besides me, and in at least one book I've read. Thickness of the plate impacts the depth of the dot/holes one can create in the plate. Presumably the deeper the dot, the more ink one can wipe in to the plate, and the more ink that gets in the more comes out, on to your print. If you're into relief printing, or the effect of open bite, the thicker the polymer, the deeper the relief lines can be as well. I probably wouldn't use the KM73 for that kind of work, since the polymer is relatively thin. I've not had problems getting deep, rich blacks once the exposure time has been established (and using Charbonnel Carbon Black ink), however. Hope that helps clarify some of the confusion.
