newspapers, and fine screen rulings for high quality reproductions, e.g. fashion magazines or art prints (Kinyo. Halftone dots are referred to by a number based on the number of dots per linear inch.
This number is called the “frequency” or “Lines-per-inch – LPI.” Yes, lines-per-inch doesn’t seem right but in the old camera days you would refer to the halftone screen “ruling” and this is where it came from. Don’t Confuse DPI and LPI.

After exposure the plate is developed in the dark room for 2\ minutes with a glycin developer, rinsed under the tap, and then immersed in a 5.Photoengraving, any of several processes for producing printing plates by photographic means.
In general, a plate coated with a photosensitive substance is exposed to an image, usually on film; the plate is then treated in various ways, depending upon whether it is to be used in a relief.
