Abstract
A photoplotter supports a sheet of photosensitive material for exposure by an associated light source. A light valve device interposed between the light source and the sheet has a main face parallel to the sheet divided into a plurality of subareas or pixels the light transmissivities of which are individually controlled through an associated computer to cause the exposure to be that of a desired graphic or artwork.
