I have not enlarged a laser imagesetter's fine screen negative, but I have
enlarged half-tone negatives made with a sealed glass halftone screen. All
the dots and the spaces get bigger if you make reasonable enlargements. I do
it with lith film and work to maintain the % dot area with the enlargement.
Tricky if soft-dots.
I also made a glass half-tone screen with 0.1 inch wide drafting tape and
0.1 inch spaces in between. That was very interesting to me. Each dot was a
small image of the iris of the enlarging lens I used to make the half-tone
as expected. But superimposed was the part of the image, which amused me
very much.
