<p>A method for generating a latent image on a substrate surface using a low current (e.g. less than 2 x 10<-><3> amperes) electrical discharge. The apparatus may include a movable carriage or roll (10) adapted to support a coated plate (20) and move it past an imaging assembly (30). The discharge is maintained by a voltage source (60) controlled by switching means (65) in response to a pattern data processor (55). The invention may be used, for example, to image lithographic plates, which plates may or may not contain a light-sensitive material, from a digital source of image data.</p> |
