Re: polymer plate drying time


I don't seem to. Much of my work has texture to it, so that helps, but recently I made a print with a smooth sky graduating to dark grey and that was OK.

I'm really not doing anything physically different or extreme. My darkroom tends to be quite dry though - right now it's at 23%RH. I blot the plate very quickly with newsprint (plate face UP - not down) and replace it with fresh paper almost immediately. You have to be extremely careful though, because as you know, the plate's very tacky at this point and you have to work quickly.

So Keith,

Do you have any problems with the KM73s and OHP with those patches plaguing the rest of us? How do you mitigate them?

Someone recently suggested I try spraying a little silicon spray onto a rag and buffing the plate. Seems that Solarplates have a slightly viscous quality to them while the KM73s are more tacky. I'm probably going to test both with a light buffing of silicon AND 4 passes with the Kyrlon 1303 this weekend and see which, if either, work.

Drying seemed to help the durability quite a bit. No scratches after 7 prints. Thanks again for that feedback and advice!
