Abstract:
1. An information processor for performing an imposition process to impose pages to papers when a sheet collection comprised of a plurality of sheets on which pages are arranged in order is prepared, by combining a plurality of papers on which printing is performed in the unit of four pages and which are center-folded by being doubled over, and on which two sheets having each one page arranged on a front and a back are formed on both sides of a back section, the information processor comprising: a first sheet count judging section for judging whether a count of monochrome sheets in a monochrome sheet group is even or odd when in the sheet collection planned to be prepared, there exists the monochrome sheet group comprised of one or more consecutive monochrome sheets all of whose front and back sides are monochrome pages, between the first color sheet group when viewed from one end of the sheet collection and a next color sheet group of color sheet groups comprised of one or more consecutive color sheets on at least one of whose front and back sides a color page is arranged; a second sheet count judging section for judging whether a count of sheets from the one end of the sheet collection to a sheet immediately before the monochrome sheet group is odd or even, if the first sheet count judging section judges that the count of the monochrome sheets in the monochrome sheet group is even; a determination section for not only determining that the sheets in the monochrome sheet group and each one sheet lying before and after and sandwiching the monochrome sheet group are sheets of a saddle-stitched group formed of papers for saddle-stitching, but also determining that sheets lying more on the side of the one end of the sheet collection than the determined sheets are sheets of an adhesive bound group formed of papers for adhesive binding if the second sheet count judging section judges that the count of the sheets from the one end of the sheet collection to the sheet immediately before the monochrome sheet group is odd, and if the second sheet count judging section judges that the count of sheets from the one end of the sheet collection to the sheet immediately before the monochrome sheet group is even, not only determining that the sheets in the monochrome sheet group and at least two sheets each lying before and after and sandwiching the monochrome sheet group are sheets of a saddle-stitched group, but also determining that the sheets lying more on the side of the one end of the sheet collection than the determined sheets are sheets of an adhesive bound group, and determining whether each sheet of the sheet collection is a sheet of the saddle-stitched group or a sheet of the adhesive-bound group, by sequentially performing this process towards other end of the sheet collection and to sheets whose group has not been determined; and a transmission section for transmitting to one or more printing devices image data of corresponding four pages as monochrome image data if image data of all pages is monochrome image data and as color image data if image data of at least one page is color image data, so that the sheets of the saddle-stitched group or the adhesive bound group determined by the determination section are formed by respective papers.
