ABSTRACT:
The invention basically comprises systems and methods relating to the field of electrostatics and is concerned with multicolor electrostatic reproduction, printing or constituting on coated and uncoated print receiving media with multilayer apertured elements or screens carrying charge distributions in accordance with selected color separation patterns. Ions accelerated through the apertures of the multilayer element pass therethrough under modulation control dictated by the color separation pattern, thereby forming a modulated ion stream having a cross-sectional density pattern corresponding to the color separation pattern. Electrostatic latent images are formed with modulated ion streams and are developed in various ways.
