Screen Ruling

Screen ruling (also called screen frequency or half-tone resolution) is the number of screen lines per unit of length. It is measured in lines per inch (lpi). The higher the lpi, the greater the amount of detail in an image. The kind of cartonboard and the choice of printing method govern the screen ruling that can be used during printing.
