Halftone screen frequency

The halftone screen frequency determines the number of dots used to create the image. The screen frequency is measured in lines per inch (LPI). This measurement refers to the number of rows of dots per inch.

When you choose a screen frequency, remember that the higher the frequency, the sharper the image. However, there are limits to screen frequency; these are determined by the type of printing press on which you are printing and the type of paper you are using. In general, a screen frequency of 85 LPI works on newsprint, and a frequency of 133 LPI works
