ABSTRACT:
An electrostatographic printing process forms one or more colorless toner images in combination with at least one color toner image produced in an electrostatographic way on a receptor element. The information for producing an electrostatic latent image corresponding with the colorless toner image derives from a digital electrical signal representing (i) the spatial boundaries of the colorless toner image and (ii) the amount of deposited colorless toner per pixel. The receptor element is conveyed past a number of toner-image producing electrostatographic stations. At each image-producing station an electrostatic latent image is formed on a rotatable endless surface; toner is deposited on the electrostatic latent image to form a toner image on the rotatable surface, and the toner image is transferred from its corresponding rotatable surface onto the receptor element.
