Sandy, I guess it doesn't hurt to set the paper (just to be on the safe side). I printed the negative this afternoon and I am waiting for it to dry. By looking at it, it's way more thin than the previous test I printed just winging the numbers in a profile but that should be OK as I need to print it with gum. This time I used the UV test chart in QTR to print a test tablet and get some real-life values (using the steps documented by Clay Harmon). I hope to print the new step tablet in the next few days, and probably ask for advice...again. Thanks for the help. Luciano
