This was my first duty at this place; I had to hand feed 24 X 30 sheet of ozalid paper into this high speed machine.
There was a sheet of matt film, about .oo7" think with a positive line image that would then be "burned" onto the paper.
I often made about 30 to 50 copies, one at a time; the paper would collect at the top.
