Calibration method for printing apparatus using photosensitive media

摘要

A method for mapping a limited number of input data values to a larger number of output exposure values for an clectro-optical exposure device in a printing system (10) for photosensitive medium (30) in which, based on a computed contrast ratio for the photosensitive medium (30), the electro-optical exposure device is profiled and its output exposure energy curve adjusted to obtain the desired exposure energy over the range of input values.
