Why screen angles should differEdit
In offset printing, colors are output on separate lithographic plates. Failing to use the correct set of angles to output every color may lead to a sort of optical noise called a moiré pattern which may appear as bands or waves in the final print. There is another disadvantage associated with incorrect sets of angle values, as the colors will look dimmer due to overlapping.
