One of the weird experiences I had in college was working for the paper in the 90s. We has desktop publishing but the photos for the paper were taken out back to a machine with a screen copied them into solid black dots of various sizes. They were waxed onto printed newspaper pages and wisked off to the printer. I often wondered how you would reproduce it digitally but apparently I was thinking about it wrong. Halftone is the term https://en.m.wikipedia.org/wiki/Halftone https://en.m.wikipedia.org/wiki/Halftone
