Description

  The present invention relates to a booklet data creation technique for creating booklet data corresponding to a booklet, and more particularly to a technique for creating a plurality of booklet data from booklet data composed of page data in units of pages and spread pages.

  In recent years, with the spread of DTP (Desk Top Publishing) and the like, the print orderer edits the image input from the scanner on the computer software on the computer software and outputs the final printed matter directly to the recording paper in full digital form. Things have been done. Further, with the full digitization, applications such as production of printed materials in small lots, POD (Print On Demand), and variable printing have been developed.

  In the conventional printing method, page printing is performed in units of 8 pages or 16 pages on one side of the recording paper for efficient printing. Therefore, in the conventional printing system, editing is performed by assigning page data in units of 8 pages or 16 pages so that one output data is arranged in the order of the number of pages when the data for output is collated.

  Incidentally, an electrophotographic image output apparatus such as a color laser printer has come to be used in a full digital printing system used for manufacturing a printed matter in a small lot, POD, variable printing or the like. This is accompanied by a good cost balance of such an image output apparatus, and speed and quality.

  In an electrophotographic image output device such as a color laser printer, it is difficult to output to a large size recording paper due to its structure. Therefore, imposition is generally based on the assumption that saddle-stitching and saddle stitching are performed, and imposing two pages on one surface of the recording paper.

  Therefore, in a printing system equipped with an electrophotographic image output device such as a color laser printer, a reconfiguration process is performed in which data of each page is rearranged so that it is aligned on the same sheet when being folded or saddle-stitched. The output is performed above (see, for example, Patent Document 1).

  Also, assuming that an electrophotographic image output device such as a color laser printer is used, the cutting position changes between the inner side and the outer side of the fold according to the thickness of the recording paper. Techniques such as placing them together have also been developed (see, for example, Patent Document 2).

In the present invention, the booklet data is not composed of only the page data corresponding to the number of pages corresponding to the booklet intentionally in the client terminal 2, but includes the number of pages to be composed of a plurality of booklets. For example, the data includes all pages of the booklet to be bound that are not distinguished on a booklet basis. It should be noted that the client terminal 2 may be used in order to avoid troubles caused by the large file size due to the creation of booklet data including all page data, or when a plurality of producers create one booklet data. From the above, a part of the booklet data divided on an arbitrary page may be sent to the print control apparatus 3, and in this case, the print control apparatus 3 may combine them into one booklet data.

  The print control apparatus 3 to which the booklet data is sent is configured by a computer (not shown) configured with a CPU, RAM, HDD, and man-machine interface. The print control apparatus 3 divides the booklet data to create booklet data corresponding to a plurality of booklets. That is, page data is created from booklet data, the page data is divided into a plurality of booklets, and booklet data that forms one booklet in the same division is created.

  Further, the print control apparatus 3 sends the booklet data as one print job to the image output apparatus 4, and controls the image output apparatus 4 and the bookbinding apparatus 5 to create a printed matter, and also performs saddle stitching and center folding bookbinding. Let it be done.

  The booklet data is data for each booklet when the booklet corresponding to the booklet data is divided into predetermined number of pages and made into booklets for each category, and is composed of each page data constituting one booklet. The page data corresponds to an image drawn on the page in the booklet, and is image data in which page data arranged on the same page is paired when divided into booklets, or page data in a spread page unit.

  The image output device 4 is, for example, an electrophotographic printer such as a color laser printer, and includes an image scanner and a plurality of paper feed cassettes that store recording sheets of different sizes in different output directions (vertical and horizontal). It is a multifunction printer.

  The image output device 4 serves as an output unit, and outputs the sent booklet data on a recording sheet as one print job. The created printed material becomes a printed material in a booklet format based on the booklet data. In addition, when one print job is completed, the print control device 3 conveys the created printed matter to the bookbinding device 5 for each booklet data unit, that is, for each section.

  The bookbinding device 5 is a device that performs saddle stitching and center folding. The bookbinding device 5 serves as a bookbinding means, and the printed matter conveyed from the image output device 4 is folded into a booklet in units of booklet data, that is, for each section.

  Next, the configuration and operation of the print control apparatus 3 will be described in more detail. FIG. 2 is a configuration diagram of the print control apparatus 3 according to the present embodiment. As shown in FIG. 2, the print control device 3 includes a control unit 3a including a CPU, RAM, and HDD (not shown), and an input device 3b that is a man-machine interface such as a mouse and a keyboard.

  The control unit 3a controls the operation of the image output device 4 and the bookbinding device 5, and also executes a print control program stored in the HDD by the CPU, thereby causing the data storage unit 31, the booklet unit 32, and the image processing unit to be executed. 34 and a booklet unit setting storage unit 33. The print control program includes a booklet data creation program, and causes the print control apparatus 3 to function as the booklet unit 32 and the booklet unit setting storage unit 33 in particular.

  Specifically, the data storage unit 31 is configured by a RAM or an HDD, for example, and stores data such as booklet data and booklet data. The data stored in the data storage unit 31 is appropriately read out by the booklet unit 32 or the image processing unit 34 and stored in the data storage unit 31. The booklet data sent from the client terminal 2 is first stored in the data storage unit 31.

  The booklet generating unit 32 is constituted by, for example, a CPU, and creates booklet data from booklet data. The number of pages of the booklet when dividing the booklet into booklets corresponds to the value of the number of pages in booklet units stored in the booklet unit setting storage unit 33.

  The image processing unit 34 is constituted by a CPU, for example, and performs image processing on the booklet data and converts it into data that can be output by the image output device 4. Image processing performed by the image processing unit 34 is RIP processing and halftone processing.

  RIP processing interprets booklet data described in a page description language, and raster data in which page data included in the booklet data is matched to the output resolution of the image output device 4, that is, bitmap data that is a collection of points. This is so-called rasterization.

  The halftoning process is a process of reconstructing the paper data composed of raster data with halftone dots in accordance with the output resolution of the image output device 4, particularly when the image output device 4 is a device that can vary the output intensity. Is reconfigured into multi-value halftone dots to generate booklet data composed of halftone dot data.

  In the printing control apparatus 3, when booklet data is stored in the data storage unit 31, the booklet generation unit 32 refers to the value of the number of pages stored in the booklet unit setting storage unit 33 and converts the booklet data from the booklet data. create.

  The page data included in the booklet data is subjected to RIP processing and halftone processing by the image processing unit 34, respectively. The booklet data after the image processing is sent to the image output device 4 together with control commands for controlling the operations of the image output device 4 and the bookbinding device 5 by the control unit 3a.

  The booklet unit 32 will be described in more detail with reference to FIG. FIG. 3 is a configuration diagram of the booklet unit 32. As shown in FIG. 3, the booklet generating unit 32 includes page data creation means 32a, sorting means 32b, and page data creation means 32c. A booklet data creation means is realized by the sorting means 32b and the page data creation means 32c.

  The page data creation means 32a sequentially reads the description contents of the booklet data in page units or spread page units, and creates page data in page units or spread page units. Page numbers are assigned to the created page data in the order of reading. At this time, two consecutive page numbers forming the spread are assigned to the page data corresponding to the spread page.

  The page number allocation is performed by creating a page number allocation table in which the page number and the address destination where the corresponding page data is stored, and the page number allocation table is stored in the data storage unit 31. Also good.

  The sorting unit 32b sorts the plurality of divided page data into a plurality of groups. The classification in the classification means 32b follows the following (1) to (3).

  (1) A group including page data for each spread page is classified so that the number of page data before and after the page data of the spread page is the same. In other words, for a group including page data in a spread page unit, the page data in a spread page unit, the first page data group composed of page data before the page data in the spread page unit, and the spread page unit The second page data group consisting of page data after the page data is divided into the same section. Further, the page number of the first page data group and the page number of the second page data group are divided so as to be equal.

  (2) As long as the spread pages are not included, the page data is divided in page number units corresponding to the value of the page number as the booklet unit stored in the booklet unit setting storage unit 33.

  (3) According to the classifications (1) and (2) above, an isolated page data group that is less than the number of pages corresponding to the value of the number of pages to be generated as a booklet unit has a number of pages that is a multiple of 4. The number of pages before and after in the above (1) is adjusted, and one group is divided by these isolated page data groups.

  The page data creation means 32c reads out the page data of the same section from the data storage unit 31, and synthesizes a pair of page data arranged on the same page when one booklet is formed from the page data of the same section. Create paper data and get booklet data.

  In the booklet, pages are lined up in the order of the numbers when they are folded or saddle-stitched. In the same section, the paper surface data creating means 32c pairs the outer page data in order, and composes the paired page data to create paper surface data. The second sheet surface,..., And the output paper surface are allocated, and these are used as a set of booklet data.

  At this time, the classifying unit 32b classifies the page data of the spread page so that the page data before and after the page data of the spread page is the same number, and the page data of the spread page is as follows. This is a single piece of paper data.

  The operation of the sorting means 32b will be described in more detail based on FIG. As shown in FIG. 8, first, the sorting unit 32b reads the value stored in the booklet unit setting storage unit 33 (S100).

  Next, out of undivided page data that has not yet been divided into groups, the page data corresponding to the read value is the number of pages to be judged, that is, page data in which a plurality of pages are allocated to the judgment target, that is, pages of spread pages It is determined whether or not data is included (S101).

  For the first determination, the unclassified page data is up to page data having a page number corresponding to the value read from the first page. As for the determination, referring to the page number allocation table stored in the data storage unit 31, it may be searched whether there is an address destination to which a plurality of pages are allocated.

  When there is no page data of the spread page as the determination target (No in S101), the page data as the determination target is classified into the same category (S102). This division is performed by binding the divided page data with one job.

  When the page data of the spread page exists in the determination target (S101, Yes), the number of pages of the page data before the page data of the spread page among the page data to be determined is calculated (S103). Further, a value added to the larger page number among the page numbers assigned to the page data of the spread pages is calculated (S104).

  This operation tentatively covers the range in order to classify the page data of the same number of pages before and after the page data of the spread page as the same division.

  Next, it is determined whether page data of a new spread page exists from the page data of the spread page to page data to which a page number corresponding to the calculated value is assigned (S105).

  The determination may be made in the same manner as the determination made in S101. In this operation, when the range of the provisional division in S103 is converted into a booklet, the image corresponding to the page data of the spread page existing in the division range is positioned on the innermost side of the booklet when the booklet is folded or saddle-stitched. It is determined whether the data is output on the same sheet without being divided.

  When page data of a new spread page exists (S105, Yes), the page data from the minimum page number to the fourth page among the determination targets is excluded from the determination targets, and a new determination target range is defined ( Steps S106) and S103 to S105 are repeated until the page data of the new spread page is not included in the determination target.

  In this operation, by excluding page data by multiples of 4, the excluded page data becomes a group of multiples of 4, and it is possible to make a booklet in a group of these excluded page data as one unit. It becomes.

  When page data of a new spread page does not exist (S105, No) and there is no page data excluded from the determination target (S107, No), the page data that is the determination target, that is, the unclassified page data The page data having the minimum page number to the page data including the page data of the spread page and having the page number corresponding to the value calculated in S104 are classified into the same category (S108). This classification is also performed by combining them into one job as in S102.

  If there is no page data of a new spread page (S105, No) and there is page data excluded from the determination target (S107, Yes), the excluded page data is classified as the same category (S109). Further, the page data of the spread page is included from the page data having the minimum page number excluding the excluded page data from the page data to be determined, that is, unclassified page data, and finally calculated in S104 Up to page data having a page number corresponding to the determined value is classified as the same category (S110).

  When the classification of S102, S108, and S110 is completed, it is determined whether or not uncategorized page data exists in the page data created by the page data creation unit 32a (S111).

  If unsorted page data exists (S111, Yes), the process returns to S101 and repeats S101 to S110. If unsorted page data does not exist (S111, No), the sorting by the sorting means 32b is terminated. .

  If the number of pages of uncategorized page data is less than the value stored in the booklet unit setting storage unit 33, the page data may be classified into the same classification and the classification may be terminated.

  The booklet data created by the booklet generating unit 32 is shown in order in FIGS. FIG. 4 is a diagram showing the creation of page data based on the booklet data by the page data creation means 32a. FIG. 5 is a diagram showing an example of page data classification by the classification means. FIG. 6 is a diagram showing that booklet data is obtained by making the page data into the page data so as to create one booklet with the same division by the page data creation means 32c.

  As shown in FIG. 4, in the booklet data, for example, arrangement specifications of character data and graphic data for 48 pages are described. The third read data, the 31st read data, and the 38th read data are described in units of spread pages.

  The page data creation means 32a reads out character data and graphic data from the booklet data in units of pages or spread pages together with the layout rules, creates 45 page data including page data of three spread pages, and sequentially Assign a number.

  As illustrated in FIG. 5, for example, the booklet unit setting storage unit 33 stores a value of “16”. The sorting means 32b first determines page data from the first page to the 16th page as unsorted page data.
