QTR-Quadtone RIP

I find using the front feed to be troublesome with some 3880s and not troublesome with other 3880s when using pictorico film. The printers (I’ve tested on 6 3880s) throw too many sensor errors and when you turn the sensors off this also causes problems. This is why I developed the method described below . . .

It’s important to only load the Pictorico a single time without error to minimize abrasions to the emulsion surface caused by other non-star rollers, etc.

I also had start-wheels happen on a few of the 3880s when using front-feed . . . so, decided to get rid of them essentially.

best,
Walker
