Each plate transfers a lot of it with a rubber blanket and the blanket offsets a lot of it on top of the paper.
Most commercial printers use conventional AM (amplitude modulated) line screens, which are dots arranged inside a rosette pattern to makes images. This means each screens plate needs to align perfectly at very high-speeds of rotations of the press cylinder to keep registration sharp. At typical press run speed alignment with the plates may be unstable. The way works offers some dots are large and a few dots are small according to their tonal value. The bigger the dots the more ink they pick-up.
