Abstract
Abstract Apparatus for producing multicolor images by color substractive method. An image is projected through a colored filter onto the printing paper. A xerographic toner image is then developed in all areas of the printing paper except the areas of the desired color. The image in the desired color area is then dyed, the xerographic toner image preventing dying in undesired areas. The toner image is then removed and the process repeated for the remaining colors.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
27 words
The apparatus of claim 1 wherein said means for transferring a developed xerographic image to said dye transfer material includes transferring a plurality of developed xerographic images.
Claim 2
Dependent Claim
127 words
Apparatus for printing full color image reproductions comprising an electrically conductive cylinder, means for securing of dye transfer material to said cylinder, indexed guide rails for guiding said cylinder along an indexed path, transfer means for transferring developed xerographic images to said dye transfer material, fixing means for fixing transferred xerographic images to the dye transfer material, dye means for dyeing the dye transfer material in nonimage areas, and means for removing the xerographic image from the dye transfer material so that successive transfers of three color separated xerographic images in register, each transfer followed by a dye treatment using a dye of complementary color to the color represented by the respective color separated xerographic image, produces a final full color reproduction on the dye transfer material.
Claim 3
Dependent Claim
58 words
Xerographic printing apparatus comprising a transfer station for transferring a xerographically formed powder reproduction to dye absorbent paper, a fixing station for fixing said powder reproduction to said dye absorbent paper, a dyeing station for dyeing said dye absorbent paper in uncovered areas, and a resist removing station for removing said powder reproduction from said dye absorbent paper.
Claim 4
Dependent Claim
92 words
Color printing apparatus comprising three transfer stations for transferring xerographically formed powder images from xerographic plates to color absorbent layers, three fixing stations for fixing the powder images transferred in the three transfer stations, three dyeing stations for dyeing the color absorbent layers on which the powder images have been fixed by the three fixing stations and three resist removing stations for removing fixed powder images from color absorbent layers after the layers have been dyed in said dyeing stations and means to move the color absorbent layers through the said stations.
Claim 5
Dependent Claim
96 words
Apparatus for forming an image pattern xerographically comprising means to form an electrostatic latent image on a first surface, means to form a first developed image from said latent image with electroscopic particulate material, means to transfer said first developed image to a second surface, means to fix said first developed image to said second surface, means to form a second developed image by flooding the second surface with an image forming material that is resisted by the material of the first developed image, and means to remove the first developed image from the second surface.
Claim 6
Dependent Claim
88 words
Apparatus for printing full color image reproductions comprising a cylinder for maintaining a dye transfer material, means for moving said cylinder along a predetermined index path, transfer means for transferring developed xerographic images to the dye transfer material, means for fixing transferred xerographic images to the dye transfer material, means for dyeing the dye transfer material in nonimage areas, means for removing the xerographic image from the dye transfer material enabling successive transfers of xerographic images in register, each followed by dye treatment of the dye transfer material.
