So I recently learned how they used to make halftones for newsprints of photographs. They had a filter that was covered in tiny cones. The intensity of the light passing through the cone determined the size of the dot that would appear on the other side. Does anyone know what the formal term for these sheets are? I'd like to find some to make halftones from film negatives.

Okay, so I've learned they're just called halftone screens. I know I could do this digitally, but I want to do it the old analogue way for no reason.

Bigger discussion about this would be really cool. I've been making kind of an exploratory hobby of halftone silkscreen experiments. Wrote a couple of Gimp plug-ins to mess with myself.
As a contribution, some further reading about the big pitfall (or happy side-effect, however you look at it):

You need contact screens. They used to be common, Kodak and others made them. Not sure where you could find them now.

This being /diy/ I bet there's a way to improvise screens if OP's not looking for professional quality at the moment.

They're hundreds of dollars on ebay, so I'm sure that would be the best option.I can't even find images of the contact screens themselves. If we could get a good look, we could figure out how to emulate them.

Dot screens can be used as a substitute.
