Abstract

Mixed reproduction job integration by appropriate inserts of color bearing sheets into primarily black and white job sets before set binding or finishing is a well known, common, practice, as don& manually, or by off-line inserter/collators. Color sheet insertion integration is also done by manually stacking pre-printed color image or color highlight printed sheets into the regular paper tray, or a special insert tray, of a black and white (black only) copier or printer, which is programed to feed those sheets interleaved at the proper selected page locations by known inserts or chapterization software controls, in a predetermined manner to obtain collated output sets.

Mixed reproduction job integration by appropriate inserts of color bearing sheets into primarily black and white job sets before set binding or finishing is a well known, common, practice, as don& manually, or by off-line inserter/collators. Color sheet insertion integration is also done by manually stacking pre-printed color image or color highlight printed sheets into the regular paper tray, or a special insert tray, of a black and white (black only) copier or printer, which is programed to feed those sheets interleaved at the proper selected page locations by known inserts or chapterization software controls, in a predetermined manner to obtain collated output sets.

Xerox Corporation output sheet inserter patent art includes U.S. 4,961,092, 4,602,776, 4,924,265 and 4,330,197 (Col. 5, lines 55-58, and tray 108 in the Figure). Other art on this subject includes US. 4,248,525 and 4,893,153. Eastman Kodak US. 4,893,153 to Milton S. Sales, et al., discloses copying interleaved color and black only original sets on a single copier, by copying all of the colored originals first and temporarily storing the color copies, then copying the black only pages of the set, and then interleaving (inserting) the color pages in the correct places in the output to get collated copies. This approach avoids more frequent switching between process color and process black. However, this approach requires a single copier or printer which is capable of both full color and black only printing, typically much more expensive and slower than many available high speed black only copiers and printers. See also Canon US. 4,476,486; 4,521,805; 4,527,885; and especially 4,587,532 on digital job sharing copiers.

The system disclosed here provides for automatic integration of an inherently slower color printer with a high speed black only printer to output collated job sets of black only copy sheets with color inserts sheets, at or near the full normal high speed copying rate of the high speed black only printer. That is, this system is not limited to the normally much slower, more expensive and less reliable copying rate of a full color printer.

This disclosed system herein is suitable for efficient reproduction of any type of original documents, especially a typical document set mix of mostly black only pages only needing a black only printer or copier, but containing a few color image sheets at certain desired page locations. That is, color image insert sheets requiring highlight or full color printing.
