After an end-of-term delay, I have started serious research in how to make the perfect photo-polymergravure plate/print. Last term, we worked with Mitch, a gravure colleague, in getting the basics and understanding the need for serious testing. I then bought the eBook "Precision Digital Negatives" by Mark Nelson and discovered the wonders of a fantastic colored digital positive/negative and precise calibration for all contact processes, including polymergravure. I've now posted my first test image (after numerous test step-scales), and it is so close, I can taste it. I am also using one of Mark's fine polymergravure screens, so the detail is amazing.
