Each plate transfers some of it to a rubber blanket and also the blanket offsets some of it on the paper.
Most commercial printers use conventional AM (amplitude modulated) line screens, which are dots arranged inside a rosette pattern to makes images. Which means each screens plate needs to align perfectly at very high-speeds of rotations of the press cylinder to hold registration sharp. At typical press run speed alignment in the plates can be unstable. The way it works is a few dots are large and some dots are small depending on their tonal value. The higher the dots the harder ink they pick-up.
