This sounds very promising - I am already using the SE ink set to make digital transparencies for polymer gravure here at school. (Yes, it is working I am using a 2 exposure method similar to the one in my older Piezo blog post, not DTP, and I will share details re this soon, just been too busy to sit down and write coherently) I have been asked to set up a system for a workshop/studio in Port Washington, where I am doing a project residency. Just picked up a gently used 4800 for them very cheap, and will be buying carts and inks for it soon. I was planning to use the SE K7 set up I am already using - The workshop/studio is interested photography and printmaking, as of now they know nothing about quality BW digital printing at all and wanted the ability to make paper prints as well - So the questions - if the new Piezo Pro can do dual duty for both DN and paper prints it may be the way to go, for this application - as it offers more options than a straight selenium or SE set. -Will I definitely need PP the software package in addition to the PPinks? Will the dual K4 curves work with only 8 slots? Or will I need to stick with a K7 plus GO set-up?
