Screens as in physical filters. It's a paper printing semi-analogue process to solve the problem (not enough colors, need to simulate colors spatially) that that semi-digital electronic screens use dithering for. It's dual to "anti-aliasing", where we use an abundance of colors to simulate missing spatial resolution.
