analogue halftoning/lithography process information/guides?

Nope, we used a high contrast print paper and a halftone screen on top with glass. Used a dim lamp for the highlight bump exposure. Same handling as making the halftone negs just going direct from the continuous tone negative. I think the screen was a special profile for under the enlarger prints.
No point in doing so many steps to get the image. We did plenty of pmt shots as well for outside sourced prints for publication.

Ive use many Caprock brand screens

Camera Screens and Tints for conventional pre-press halftones in cameras and enlargers, new white dot screens for copiers.

Got it. Similar to making a PMT, just reverse the elements. It seems it would be a pain to get the exact cropping or percentage enlargement doing it that way.
