Abstract

<P>PROBLEM TO BE SOLVED: To prevent a situation that created imposition PDFs cannot be drawn or printed by a PDF viewer or a printer due to such reasons that the number of drawing objects is too much, the PDFs do not correspond to a drawing instruction, or the like. <P>SOLUTION: A imposition PDF creation system is provided with a means for inputting documents, an imposition control means for controlling imposition of documents, an imposition PDF creation means for creating PDFs imposed according to imposition information of the imposition control means, and an imposition PDF output means for outputting imposition PDFs. When the number of drawing objects in a target page imposed on the same page is larger than a threshold, the PDF creation means executes RIP processing of these drawing objects to an imposition state to convert the drawing objects to images and then creates imposition PDFs, and when the number of drawing objects is smaller than the threshold, corrects PDFs as they are and creates imposition PDFs. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to an imposition PDF creation system for creating an imposition PDF.

  Conventionally, when creating an imposition PDF, the imposition PDF is created in such a way that the PDF data of each page is matched to one page.

As a conventional example, for example, a bitmap is created by RIP from an order form and an input document, a configuration confirmation file is generated, the URL is notified to the customer, and the correction is performed based on the customer's correction instruction. Yes (see Patent Document 1).

  However, with this method, if the submitted PDF contains a lot of drawing objects such as images, characters, and graphics on each page, there are drawing commands that are not supported by the viewer. There is a problem that creating an attached PDF cannot be opened with a PDF viewer, or cannot be drawn correctly, takes a very long time, or cannot create a PDF with many pages.

  In order to solve the above problems, an imposition PDF creation system according to the present invention includes a means for inputting a document, an imposition control means for controlling the imposition of the document, and an imposition information according to the imposition information of the imposition control means. The imposition PDF creation means for creating the attached PDF, the imposition PDF output means for outputting the imposition PDF, and the PDF creation means have the number of drawing objects of the target page to be imposed on the same page. When it is larger than the threshold value, it is characterized in that the imposition PDF is created after RIP to the imposition state and converted into an image, and when it is smaller than the threshold value, the PDF is collected as it is to create the imposition PDF.

  As described above, according to the present invention, even if the number of drawing objects of the created imposition PDF is large, drawing and printing can be performed with a PDF viewer or a printer.

(Example 1)
Examples of the present invention will be described below.

  An example of a printing system according to the present invention is shown in FIG.

  FIG. 2 is a flowchart showing the printing process of the present invention. A preferred embodiment of the imposition PDF creation system of the present invention will be described.

  Hereinafter, the process from the submitted PDF document to the imposition PDF file output will be described in detail regarding the operation of the imposition PDF creation unit 7. Here, a description will be given of processing after the PDF has already been submitted and the user has specified the number of impositions, paper size, position, etc. via the UI, and then selected imposition PDF file output.

  First, the number of impositions is acquired in step S201. The number of pages assigned to one page is determined by the user. This is the same as a general imposition system.

  In step S202, the target page to be impositioned in one page is determined from the imposition number acquired in step S201, and the number of drawing objects including images, characters, graphics, and the like is obtained. For example, when the number of impositions is 16, the target pages are determined such as the first 1 to 16 pages, 17 to 32 pages, and 33 to 48 pages of the submitted PDF, and the submitted PDF is converted to the submitted PDF. The number of drawing objects of the target page included is obtained. For example, if the submitted PDF holds 100 drawing objects for each page, the number of drawing objects is 100 × 16 = 1600 because there are 16 pages.

  In step S203, it is determined whether the number of drawing objects after imposition exceeds a threshold value. When exceeding, it progresses to step S204, and when not exceeding, it progresses to step S208.

  Here, the number of drawing objects for one page of imposition is 1600 and the threshold value is 500, which exceeds the threshold value, so the process proceeds to step S204.

  Next, in step S204, RIP is performed to the size printed for each target page of the submitted PDF imposed on one page, and an image is formed. For example, it is assumed that the print size is A4 and the printer for printing is “printer 1” as indicated by 305 in FIG. Here, the resolution of the printer 1 is 600 DPI. For 16 pages, 1/16 of A4, 600DPI memory is secured, and the first page of the submitted PDF is RIPed on that memory and converted into an image. The exact reduction ratio depends on the imposition control information already specified by the user.

  Next, in step S205, create the first page of the imposition PDF with a drawing command added so that the first page of the submitted PDF created in step S204 is rendered from the image created by RIP. To do. Note that the image is compressed and stored before being stored in the PDF.

  In other words, one image of 1/16 of size A4, resolution of 600 DPI, depth of 24 bits color is pasted on the first page of the imposition PDF. By doing so, in the conventional method, the number of drawing objects per page is 100, but in the present invention, the number of drawing objects is one.

  Next, in step S206, it is determined whether all target pages to be imposed within one page have been impositioned. When all the impositions have been made, the process proceeds to step S207. If all the target pages are not imposed, the process proceeds to step S204.

  Since the first page has been imaged and pasted to the imposition PDF, the second page is imaged and pasted to the imposition PDF in the same way. For example, the image of the second page is pasted on the right side where the image of the first page is pasted.

  In this way, all the target pages for the imposition page are imaged and pasted on the first page of the same imposition PDF. In the 16-page layout, 16 reduced images are attached to one page of the layout. In other words, with 16 impositions, a total of 1600 drawing objects for one page of the imposition PDF becomes 16 drawing objects.

  In step S207, it is determined whether or not all pages of the manuscript are impositioned. If all the pages are arranged, the imposition process is terminated and the file is saved according to the user setting.

  If not completed, the process proceeds to step S202 to further create an imposition PDF page.

  Here, an example will be described in which the number of objects on one page after imposition in step S203 is within a threshold value of 500 and the process proceeds to step S208. In step S208, a page after imposition is created in a form that gathers the resources and drawing commands of each page and creates a PDF. In step S207, it is determined whether all pages of the document have been imposed.

  In this embodiment, the threshold value of the number of drawing objects is compared for each imposition page, but the same effect can be obtained by comparing the drawing object number of the entire imposition PDF with the threshold value.

(Example 2)
Embodiment 2 of the present invention will be described below.

  An example of a printing system according to the present invention is shown in FIG.

  FIG. 4 is a flowchart illustrating print processing according to the second embodiment. A preferred embodiment of the imposition PDF creation system of Embodiment 2 will be described.

  Hereinafter, the process from the submitted PDF document to the imposition PDF file output will be described in detail regarding the operation of the imposition PDF creation unit 7. Here, a description will be given of processing after the PDF has already been submitted and the user has specified the number of impositions, paper size, position, etc. via the UI, and then selected imposition PDF file output.

  First, in step S401, it is determined whether the PDF version of the document is a printable version of the printer. If it is a printable version, the process proceeds to step S409, and pages after imposition are created for all pages in a form that gathers resources and drawing commands for each page, and is set as PDF. The process in step S409 itself is a general process.

  If it is not a printable version, the process proceeds to step S402.

  For example, if the PDF version of the submitted PDF is PDF1.5 and the compatible PDF version that can be printed by the printer specified by the user is PDF1.3, the process proceeds to step S402. In another case, if the PDF version of the submitted PDF is PDF1.3, proceed to step S409 to create an imposition PDF as it is.

  Next, in step S402, a target page to be impositioned within one page is determined from the number of impositions set in advance by the user, and the process proceeds to step S403.

  For example, if the number of impositions is 16, the target pages will be fixed, such as the first 1 to 16 pages, 17 to 32 pages, and 33 to 48 pages of the submitted PDF. Here, it is assumed that the first 1 to 16 pages are confirmed.

  Next, in step S403, one page is extracted from the target page. Here, it is assumed that the first page is taken out. Then go to step S404.

  In step S404, it is determined whether the page can be printed by the printer. If printing is possible, the process proceeds to step S410, and the resources used on the page and drawing commands are used as they are, and the position is moved and reduced according to the imposition information specified by the user, and the state after imposition The PDF.

  For example, when examining the resources, drawing commands, etc. in the first page of the submitted PDF confirmed in step S403, transparency is specified as the specification of PDF1.4, and the printer supports only up to PDF1.3. If it is not possible to print correctly with the printer, go to step S405.

  Next, in step S405, RIP is performed to the size printed for each target page of the submitted PDF imposed on one page, and an image is formed.

  For example, it is assumed that the print size is A4 and the printer for printing is “printer 1” as indicated by 305 in FIG. Here, the resolution of the printer 1 is 600 DPI. For 16 pages, 1/16 of A4, 600DPI memory is secured, and the first page of the submitted PDF is RIPed on that memory and converted into an image. The exact reduction ratio depends on the imposition control information already specified by the user.

  Next, in step S406, the first page of the imposition PDF to which a drawing command is added so as to be drawn from the image created by RIP from the first page of the submitted PDF created in step S405 is created. Note that the image is compressed and stored before being stored in the PDF.

  For example, an image of 1/16 of size A4, resolution of 600 DPI, and 24-bit color depth is pasted on the upper left of the first page of the imposition PDF.

  Next, in step S407, it is determined whether all target pages to be imposed within one page have been impositioned. When all the impositions have been imposed, the process proceeds to step S408. If all the target pages are not imposed, the process proceeds to step S403.

  The image of the first page of the submitted PDF and pasting to the imposition PDF have been completed, so the next determination is made in the same way for the second page. Paste. For example, the image of the second page is pasted on the right side where the image of the first page is pasted.

  In this way, all pages that need to be imaged with respect to the target page for one imposition are imaged and pasted on the first page of the same imposition PDF, and pages that do not need to be imaged are used on that page. The existing resources and drawing commands are used as they are, the position is moved and reduced, and merged into the imposition PDF.

  Next, in step S408, it is determined whether all pages of the submitted manuscript have been imposed. If all the pages are arranged, the imposition process is terminated and the file is saved according to the user setting.

  If not completed, the process proceeds to step S402 to further create an imposition PDF page.
