I've been thinking about trying to make some masks for my enlarged negatives for contact printing (platinum and maybe soon carbon). Since I don't have any registration equipment to do it during enlargement, I was thinking if I made the mask from the enlarged negative I could register it well enough visually for contact printing.
Has anyone tried this or anything similar? I made a couple of tests the other day with some ortho litho film in d23, which seemed promising but I didn't get anything completed. I was picking up a weird grainy texture on the mask from something in my setup and ran out of time before I could sort it out.
