COLOR SEPARATION SYSTEM EVALUATION.
Abstract
An experimental optical scanner is capable of detecting and identifying eight different colored pencil lines on a map compilation manuscript. Reflected tungsten illumination, a lens, a single dichroic mirror, and two solid state photosensors are the major elements comprising the color head; the decoding logic is all digital. A scanning rate of 30,000 data bytes per second, plus simultaneous color encoding, can be achieved. A color coding method for the compiler is recommended which would tag each drawn line or point for its position, separation negative, and its TM-23A output symbol. Scanning and computer processing of this color line data for an eventual output negative plotting system is discussed. (Author)
