Hi Bob,

Positives are on Pictorico TPF100, printed on an Epson 7890 or 3880. The process of linearization and the creation of contrast curves for the process, while striving for a density range of 1.55, is a bit of pain but at least it doesn't have to be done too often, unless of course exposure units start acting funny, dichromate exhaustion, etc. There are also the issues of density variations with pigment inks...anyway I digress here and this is really DPUG material anyway

Largest copper plates I can handle are 16x20. Copper is so damn expensive that when you trash a couple of those, it hurts.

Hope all is well,
