Repeat usage of polyester sheeting?
After a couple of very helpful replies to my query on this forum about polyester sheet supplies, Secol are sending me some 50 micron thickness sheets for placing between negative and Arches Platine paper when Ziatype printing.
Is the polyester sheet usable only once for this purpose, thinking that perhaps emulsion may adhere to the sheet and foul a second print, or can the same sheet be used several times?
Good idea to replace those sheets
I ruined one neg, and got a few spots on another. I think because against the negative, I placed the side of the sheet that had been against the emulsion on a previous exposure.
