Abstract

Proposed is a method for generating color images by combining ionography with Non- Interactive Development (NID). The accompanying figure illustrates a full color printer 10 in which a color image is laminated to paper or a transparent film. Machine 10 includes a spool 12 of conducting film 14 on a strippable and tacky substrate layer 16. As film 14 unwinds from spool 12, an ionographic writing head 18 creates a pattern of image charges (on film 14) that are developed with a NID developer 20. Other images are sequentially added by writing heads 21, 23, and 25. These images are developed by NID developers 26, 28, and 30. NID developer 20 develops black images and developers 26, 28, and 30 develop the primary colors of magenta, cyan, and yellow. The imaged film 14 is then laminated to a final image receiver 32 by a pair of transfer rolls 36.

COLOR PRINTING BY COMBINING IONOGRAPHY AND NON- INTERACTIVE DEVELOPMENT IN A LAMINATING PROCESS (CONT'D)

Proposed is a method for generating color images by combining ionography with Non- Interactive Development (NID). The accompanying figure illustrates a full color printer 10 in which a color image is laminated to paper or a transparent film. Machine 10 includes a spool 12 of conducting film 14 on a strippable and tacky substrate layer 16.

NID developer 20 develops black images and developers 26, 28, and 30 develop the primary colors of magenta, cyan, and yellow. The imaged film 14 is then laminated to a final image receiver 32 by a pair of transfer rolls 36.

While the embodiment is described as a room temperature process, the strippable film 14 may be a thermoplastic material that becomes tacky at elevated temperatures. Thus, in an alternative embodi...
