ABSTRACT:
The invention disclosed, a microprocessor based exposure computer, automates the time consuming and tedious calibrations and calculations which were necessary to reproduce high quality copy in the field of graphic arts. The automated nature of the invention includes the ability of the device disclosed to perform a self calibrating function which greatly reduces the set-up time of the instrument which in the past has required trial and error calibrations involving the repeated manipulation of a gray scale of varying density or other variable light attenuator.
