Benefits of technology
Enables rapid and efficient production of different book versions and customized books by automating the selection and assembly of pages, reducing production time and increasing adaptability to varying content, while maintaining high-quality printing.
Problems solved by technology
In either case, conventional printing systems are not easily adaptable to produce books of these types.
While the foregoing image manipulating systems allow some image gathering capability, none is effective to assist in the rapid production of different book versions.
Of course, CAD systems are primarily designed for line art and not text or graphic images, and hence are of only limited use.
In either event, where many book versions are to be produced, such a process would be quite time-consuming.
In addition, image importation and merge routines provided as a part of word processing software are adapted for use on a sub-page basis only and hence are of only limited usefulness in the book production environment.
As a result, data to be displayed or printed must be first rasterized by a raster image processor (RIP), which utilizes complex and time-consuming computational routines which further increase production time to an economically impractical level.
Such a procedure can be computationally expensive and may limit productivity.

Embodiment Construction
[0059]FIG. 1 illustrates a prior art method of producing books, for example, as shown in the above-identified Riley et al. '818 patent. During a publishing step 20, the contents of one or more book versions are determined. Each version may comprise, for example, a set of standard or common pages. In addition, some of the versions may include one or more additional pages or other customized information. Thereafter, during a preliminary step 22, color correction of color images is undertaken together with undercolor removal and screening for halftone images. During a prepress step 24, page imposition is effected and printing cylinders or plates are prepared. The plates or cylinders are then used during a printing step 26 to prepare signatures which are loaded into packer boxes (not shown). As noted in the Riley et al. '818 patent identified above, the signatures are then selectively collected on a gathering chain (not shown) during a book assembly step 28 and the gathered signatures a...

The present invention is useful for assembling a book. The inventive method includes the steps of specifying pagination information including an indication of whether a page is to be selectively included in the book, determining whether the page is to be assembled into the book based on the pagination information, and generating page description language instructions for production of the book in accordance with the pagination information.
Description
RELATED APPLICATIONS [0001] This application is a divisional of U.S. application Ser. No. 08 / 802,337, filed Feb. 11, 1997, the disclosure of which is hereby incorporated by reference, and which, in turn, is a continuation-in-part of U.S. application Ser. No. 08 / 478,397, filed Jun. 7, 1995 and a continuation-in-part of U.S. application Ser. No. 08 / 627,724, filed Apr. 2, 1996, now U.S. Pat. No. 5,857,209.TECHNICAL FIELD [0002] The present invention relates generally to reproduction methods and systems, and more particularly to a method of and system for selectively reproducing images. BACKGROUND ART [0003] Most printing systems in use today utilize printing plates or cylinders which are engraved or photochemically processed to create an image thereon. Ink is then deposited on the plate or cylinder and the ink is thereafter transferred to a substrate, such as paper. In a conventional printing press, a number of pages are printed on a sheet of paper to form a signature which is then fol...
