Paper Abstract

Graphic arts is an industry developed over the years to describe a process enabling the printing press to reproduce in quantity a facsimile of the original. It is not intended in this paper to explain the various processes in detail but to generalise and to show how light plays an important feature. Originals, which is the term used for the 'object to be copied' can be in many forms; black/white or colour, and of varying sizes. They can be split into two distinct areas: flat copy and photographic originals.
