Abstract:
A method of printing using a spatial light modulator with ON defects, comprising the steps of:a. generating a defect map of a spatial light modulator, wherein said defect map identifies elements with ON defects;b. determining a minimum exposure level value to be added to all exposure level values, wherein a controller calculates said minimum exposure level value by determining the number and position of said ON defects in a column of said spatial light modulator;c. using said spatial light modulator to generate a latent image on a photosensitive surface, such that said ON defects have been minimized by the addition of said minimum exposure level to all of said latent image; andd. controlling the electrophotographic development of said latent image such that said minimum exposure level is eliminated from a final printed image from said latent image.
