Though I've been printing pt/pd sporadically for several years, I've decided to get more serious about it. I'd like to make a test strip to determine a Standard Printing Time, but it seems that the 4-ply matboard I normally use for making test prints under the enlarger for silver printing is not heavy enough or not UV blocking enough to work. Rather than nice clean strips across the print for each exposure increment, I get more of an overall exposure with, maybe, faint strips.
I use an Edwards Engineered Product UV exposure unit where the printing frame is placed inside the box with a door that flips down to close it. Therefore, I can't make a test strip exactly the way I do it for silver printing. I'm thinking I need some kind of UV blocking material, perhaps a few different sizes, whereby I could place a piece on top of the frame, carefully slide the frame into the exposure unit, expose, rinse-n-repeat for, at least, a few exposures across the paper?
Anyway, how do you alt process printers using UV exposure handle test strips?
Thank you for any insight provided.
