<p>Case 1545 A method for generating a latent image on a substrate surface using a low current (e.g., less than about 2x10-3 amperes), non-pulsating electrical discharge. The method may be used, for example, to image lithographic plates, with a resolution of approximately 1,000 lines/inch, directly from a digital source of image data. The discharge is confined within a thin stream of a relatively inert gas which is directed at the plate surface with a velocity of at least about Mach 0.05.</p> |
