Abstract

See full text

A platesetter may have an optical imaging head which includes a diffractive modulator having individually controlled ribbons associated with individual pixels imaged onto a printing plate. One method for reducing artifacts transferred to a medium includes the steps of: determining values of intensity versus pulse width variations for each ribbon of the modulator based upon empirical data; weighting the determined values according to a predetermined weighting factor dependent upon physical, optical, chemical and structural characteristics of a printing plate to yield an image on the printing plate having minimum visible artifacts; and applying the weighted values to ribbon drivers of the modulator.
