Also, halftone dots aren’t necessarily simple shapes. They are often designed to change shape as they go from 0 to 100% in order to have a shape that holds ink better (for some reason I don’t understand, a circle isn’t necessarily the best shape for holding its edge when made out of wet ink), and also for style (think large halftones where the dots are visibly long streaks all oriented in a particular direction which isn’t necessarily the same angle as the halftone grid). In fact, postscript allows you to prepend code that defines your own custom halftone function f(u,v) -> 0/1 (where u,v is the coordinate within the halftone cell) before printing your job, kinda like a weird little pixel shader from the 90’s.
