A screen enables a continuous tone image such as a photograph or transparency, which cannot be reproduced by most printing process, to be broken down into tiny dots which can be printed and which from a normal viewing distance give the illusion of continuous tone.
Screens are also used to print tints of solid colours by altering the size or spacing of the dots. Screens can are referred to in terms of DPI (dots per inch) or dots per centimetre and the finer the screen, the better the quality of reproduction. Newspapers use coarse screens of around 85 DPI and magazines use around 150 DPI and can go up to 400 DPI.
