1392853 Electro-phoretic printing RENKER GmbH 10 April 1972 [9 April 1971] 16412/72 Heading G2H In a method of developing electrostatic latent images to produce a multi-coloured print the latent image is so created as to form areas having different electrical potential ranges line toner material is used having different coloured particles the toner of one colour only responding to a particular potential range of the images. The particles are deposited out of liquid vehicle through electro-phoresis.
