In screen printing and the general printing industry, the screen (or plate printing) is only capable of printing solid areas. Since a photograph has various tones ranging from solid black all the way to solid white, a method has to be used where by you can reproduce the photograph in these “continuous tones” and still print a “solid” area of ink. This is where the halftone comes in. Take a gradient (like the below left) and render it as a halftone pattern, zoom in a bunch, and it would look something like the below right. The halftone printing also name dot’s printing.
The Halftones design help to cut down the cost but also can get the gradient beautiful colors. There many special membrane overlays choose the such printing design.
