Abstract
A method of forming a dot-matrix image, in which uniform light is applied to an array of light gates. The transmission of each of the light gates is controlled over several steps according to pictorial data to thus provide a finely graded image. Preferably, a contact screen converts the graded intensities to differently sized dots.
