QTR-Quadtone RIP

Make a “noisy” negative using a specific dither. Or print directly onto a polymer plate with 1 channel using a slightly different dither.

One way to do this is the print directly onto the plate with Matte black ink using the Epson (or QTR) driver and only 1 channel of ink. This creates the proper amount of pure dots. We are working on something that will be a bit more ideal for that but it is competing with lots of other things on our plates (sorry for the pun).

I’m sure Don Messick could elaborate if he was on this list.

Best,
Walker

I am not clear how the gravure positive is made differently in those terms. The screening inherent in inkjet film has never seemed to have any noticeable difference from analog film.
