Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a book data generation apparatus and a book data generation method for reading a recorded matter on which a plurality of page images constituting a book are impositioned and generating book data to which a page order is assigned for each page.
[0002]
[Prior art]
There is a demand in the printing industry to generate a copy of a book (booklet) that has already been bound. In addition, there is a desire to create a book (booklet) that is edited based on the book (booklet), not just a copy. If the digital book data when the book is created remains, a copy or edited version of the book may be created using the digital data. However, if the book was printed a long time ago, such data is rarely left.
[0003]
Conventionally, when there is no book data remaining, in order to respond to such a request for a duplicate or an edited version, a book that has been bound is read for each page or each sheet on which a plurality of pages are imposed, The book data is restored or new book data is generated by editing and compiling based on the read data.
[0004]
Also, if there is a platemaking film used when printing a book, the halftone image recorded on the platemaking film is read instead of directly reading the image recorded on the book, and edited and edited in the same way. The book data was restored and new book data was generated.
[0005]
When a recorded material such as a book or a plate-making film is recorded on only one page image for one sheet, the book data can be obtained by reading the recorded material in the page order and arranging the page data in the read order. Can be generated. However, when a plurality of page images are recorded on one sheet of recorded material, for example, when a plurality of page images are impositioned and recorded, a combination of page images recorded on the recorded material The permutation and the direction of forming each page image differ depending on the impositioned pattern.
[0006]
Therefore, conventionally, a plurality of page images included in one sheet are cut out, and the operator refers to the contents of the cut out page images to individually determine the page numbers of the page images. Book data composed of page images arranged in order was generated.
[0007]
[0008]
[Problems to be solved by the invention]
However, conventionally, for each of the cut page images, the operator assigns page numbers individually while referring to the contents of the page images, for example, referring to the page numbers recorded in the page images. By doing so, book data was generated. Therefore, the operator's work is complicated, and a considerable amount of time is required for creating the book data.
[0009]
In addition, it is conceivable that the book data is generated by the operator arranging a plurality of cut-out page images in order, but even in this case, the rearranging operation by the operator is complicated.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described based on the following examples.
[0028]
[Recorded material with multiple page images imposition]
FIG. 1 is an example of a recording sheet RM as a recorded material on which a plurality of page images are imprinted, which is used in the present invention. The recording sheet RM is a plate-making film used when printing a book or a sheet separated by disassembling a book that has been bound, that is, by removing the book binding. Hereinafter, for the convenience of explanation, the recording sheet RM will be described on the assumption that it is a plate-making film.
[0029]
FIG. 1A shows a recording sheet RM for printing a book to be bound under the conditions of the total number of pages “8”, the number of imposition pages “2”, the binding method “saddle stitching”, and the opening direction “right”. An example of a platemaking film) is shown. The recording sheet RM is composed of a total of four sheets. The first recording sheet RM (1) has the first page image PI (1) in the left area AL and the eighth page in the right area AR. Each page image PI (8) is recorded. Similarly, the second to fourth recording sheets RM (2), RM (3), and RM (4) include “seventh page and second page” in the left area AL and the right area AR, respectively. Page images PI of “third page and sixth page” and “fifth page and fourth page” are recorded. Note that the first, second, third, and fourth recording sheets RM are used when printing on the front and back surfaces of one sheet, respectively. In this way, a book (booklet) arranged in the order of pages can be completed by overlapping and folding two sheets printed using a plate-making film on which a plurality of page images PI are imprinted and performing saddle stitching. .
[0030]
FIG. 1B shows a recording sheet for printing a book that is bound under the same conditions as FIG. 1A except that the total number of pages is changed from “8” to a general “P”. An example of RM (plate making film) is shown. Here, the number of pages n is assumed to be a multiple of 4 for ease of explanation. The recording sheet RM is composed of a total of (P / 2) sheets since the page images PI for two pages are recorded per sheet. In the first recording sheet RM (1), the page image PI (1) of the first page is recorded in the left area AL, and the page image PI (P) of the Pth page is recorded in the right area AR. Similarly, in the second and subsequent sheets, “the (P-1) page and the second page”, “the third page and the (P-2) page”, ...... page image PI is recorded.
[0031]
Generally, in the nth recording sheet RM (n), when n is an odd number, the page image PI (n) of the nth page in the left area AL and the (P−n + 1) th page in the right area AR. Page images PI (P-n + 1) are respectively recorded. When n is an even number, the page image PI (Pn + 1) of the (P−n + 1) th page is recorded in the left area AL, and the page image PI (n) of the nth page is recorded in the right area AR. Note that the n-th (here, n is an odd number) and (n + 1) -th recording sheets RM form a pair and are used when printing the front and back surfaces of the paper. A book (booklet) arranged in the order of pages can be completed by overlapping and folding sheets printed using a plate-making film on which a plurality of page images are imprinted in this manner and performing saddle stitching.
[0032]
FIG. 1C shows an example of the recording sheet RM when binding is performed under the conditions shown in FIG. 1A except that the opening direction is changed from “right” to “left”. Further, FIG. 1D shows a recording sheet RM when binding is performed under the conditions shown in FIG. 1C except that the total number of pages is changed from “8” to general “P”. It is an example. As can be seen by comparing FIGS. 1A and 1C and FIGS. 1B and 1D, when the opening direction is changed, the combination of pages recorded on one plate-making film is the same. , The permutation is different.
[0033]
As can be seen from FIGS. 1B and 1D, when the total page number P changes, the combination patterns of the plurality of page images recorded on the same plate-making film are different.
[0034]
FIG. 2 is an example of a recording sheet RM used in the present invention, in which a plurality of page images are impositioned by another method. As in the case of FIG. 1, for the sake of convenience of explanation, the recording sheet RM will be described on the assumption that it is a plate-making film.
[0035]
FIG. 2A shows an example of a recording sheet RM for printing a book that is bound under the conditions that the total number of pages is “16”, the number of imposition pages is “4”, and the opening direction is “right”. The recording sheet RM is composed of a total of four sheets. In the first recording sheet RM (1), the page image PI (1) of the first page in the upper left area ALU and the eighth image in the upper right area ARU. The page image PI (8) of the page is recorded with the page image PI (4) of the fourth page in the lower left area ALD, and the page image PI (5) of the fifth page is recorded in the lower right area ARD. . Similarly, in the second recording sheet RM (2), the upper left area ALU, the upper right area ARU, the lower left area ALD, and the lower right area ARD are respectively displayed as “seventh page, second page, sixth page”. The page images of page 7 and page 7 are recorded, respectively, and the third and fourth recording sheets RM (3) and RM (4) also have the page image PI shown in FIG. It is attached and recorded.
[0036]
Note that the page images PI recorded in the lower left area ALD and the lower right area ARD are upside down. The first and second recording sheets RM (1) and RM (2) form a pair and are used when printing the front and back surfaces of the same sheet. In this way, each sheet printed using a plate-making film on which a plurality of page images are imprinted is folded, the piled-up deposits are bound, and the edges other than the binding portion are further cut, so that they are arranged in page order. A book (booklet) can be completed.
[0037]
FIG. 2B shows a recording sheet for printing a book bound under the same conditions as FIG. 2A except that the total number of pages is changed from “8” to a general “P”. An example of RM is shown. The recording sheet RM consists of a total of {ROUNDUP (P / 4)} sheets. Here, “ROUNDUP” is a function that rounds up the decimal point to an integer. Generally, when n is an odd number, the nth recording sheet RM (n) includes (4n−3) in the upper left area ALU, upper right area ARU, lower left area ALD, and lower right area ARD. ), Page image PI of (4n + 4) th page, (4n) th page, and (4n + 1) th page are recorded. When n is an even number, the (4n-1) -th page, the (4n-6) -th page, the (4th-1) -th page, respectively in the upper left area ALU, upper right area ARU, lower left area ALD, and lower right area ARD. The page images PI of the (4n-2) th page and the (4n-5) th page are recorded.
[0038]
Note that the page images PI recorded in the lower left area ALD and the lower right area ARD are upside down. The nth sheet (where n is an odd number) and the (n + 1) th recording sheet RM form a pair and are used when printing the front and back surfaces of the same sheet. In this way, each sheet printed using a plate-making film on which a plurality of page images are imprinted is folded, the piled-up deposits are bound, and the edges other than the binding portion are further cut, so that they are arranged in page order. A book (booklet) can be completed.
[0039]
As is clear from FIG. 2B, even if the total page number P changes, there is no change in the combination pattern or permutation of a plurality of page images recorded on the same plate-making film. This is because each sheet printed with the plate-making film of this imposition pattern is folded and then stacked to make up a booklet.
[0040]
As described above with reference to FIGS. 1 and 2, the imposition pattern recorded on each recording sheet RM, that is, the combination and permutation of the page images PI formed on each recording sheet RM, and the image forming direction And the like differ depending on the number of pages, the number of impositions, the opening direction, the binding method or the folding method. Therefore, in order to generate book data, these imposition patterns must be considered.
[0041]
[Image processing system configuration]
[0042]
Next, the configuration of the image processing system for realizing the present invention will be described. FIG. 3 is a configuration diagram of the image processing system 100. The image processing system 100 includes an input scanner 1, a book data restoration station 2 (hereinafter referred to as “restoration station”), a controller 3, a book data editing station 4 (hereinafter referred to as “editing station”), and a printing machine 5. The
[0043]
The input scanner 1 reads a plurality of page images PI imprinted on a recording sheet RM (plate making film) and outputs read data RD to the restoration station 2. The restoration station 2 is a computer including a CPU, a memory, a hard disk, a keyboard, a mouse, and the like, and is installed with a program for generating book data BD. The book data BD is a page ranking given to each page data. Moreover, each page data may be rearranged in page order.
[0044]
The controller 3 is a computer including a CPU, a memory, a hard disk, a keyboard, a mouse, and the like, and is installed with a program for controlling the printing machine 5 and a program for storing and managing book data BD. . The editing station 4 is a computer including a CPU, a memory, a hard disk, a keyboard, a mouse, and the like, and is a station in which a program for editing the book data BD is installed. The printing machine 5 is a printing machine that sequentially records for each page or newly impositioned data for each imposition data based on the book data BD in accordance with an instruction from the controller 3.
[0045]
[Configuration and function of restoration station 2]
FIG. 4 schematically shows the functions of the program installed in the restoration station 2. The restoration station 2 includes a reading control unit 21, an imposition pattern setting unit 22, and a book data generation unit 23 from a functional standpoint.
[0046]
The reading control unit 21 controls the operation of the input scanner 1, and the input scanner 1 outputs read data RD for each recording sheet RM according to the control. When the number of sheets of all the recording sheets RM necessary for constituting the book is S, the input scanner 1 sequentially reads the read data RD (n) (where n = 1, 2,...) Every time the recording sheet RM is read. , S).
[0047]
[Function of imposition pattern setting section]
The imposition pattern setting unit 22 sets an imposition pattern of the recording sheet RM. The imposition pattern is a layout of a plurality of page images PI to be recorded, and is a page layout as described in FIGS. 1 and 2. The imposition pattern setting unit 22 further functionally includes an imposition pattern registration unit 22a and an imposition pattern selection unit 22b. The imposition pattern registration unit 22a is a part for registering some imposition pattern information. The imposition pattern selection unit 22b sets an imposition pattern by selecting one imposition pattern information from a plurality of imposition pattern information registered by the imposition pattern registration unit 22a.
[0048]
FIG. 5 shows a data structure of the imposition pattern information IMD registered by the imposition pattern registration unit 22a. For each imposition pattern information IMD, the set name Ra1, the imposition page number Ra2, the throat movement direction Ra3, and the throat movement amount Ra4 are included. The set name Ra1 is a name composed of an arbitrary character string for the operator to identify the contents of the imposition pattern. For example, a character string such as “4-sided right-open” is set. The imposition page number Ra2 is the number of arrangement in the vertical direction, the number of arrangement in the horizontal direction, and the total of the page images PI recorded on one recording sheet RM. In the case of the imposition pattern shown in FIG. 2, “2, 2, 4” is set. The throat movement direction Ra3 and the throat movement amount Ra4 are information relating to the interval between the page images PI imprinted on the left and right. For example, when bookbinding is performed by saddle stitching, a sheet that is bound to the outside has a larger gutter (gutter opening). Accordingly, in the throat movement direction Ra3, information on whether the throat opening becomes larger or smaller as the recording sheet RM to be read later is set. In addition, a change amount of the opening difference per predetermined number of sheets (here, 100 sheets) of recording sheets RM is set as the amount of movement Ra4.
[0049]
Further, the imposition pattern information IMD includes data of the layout position Rb1 and the rotation information Rb2 for each area corresponding to the plurality of page images PI imprinted on each recording sheet RM. For example, in the case of the imposition pattern shown in FIG. 2, data for four areas, that is, the upper left area ALU, the upper right area ARU, the lower left area ALD, and the lower right area ARD are included. The layout position Rb1 indicates the vertical and horizontal coordinates of the page image PI. For example, for the upper left area ALU, the layout position Rb1 is set to coordinates (1, 1). The rotation information Rb2 indicates the direction in which the page image PI is recorded. For example, information indicating whether the page image PI is formed, for example, whether it is formed upside down is set.
[0050]
Further, in the imposition pattern information IMD, front / back information Rc1, trimming region Rc2, and page order calculation formula Rc3 are set for each layout position. The front / back information Rc1 is information indicating whether the printing is for front side printing or for back side printing. The trimming area Rc2 is the coordinates of two diagonal points of the formation area of the page image PI. In the case shown in FIG. 2B, the page order calculation formula Rc3 uses the reading order n of the recording sheets RM as a variable parameter. Further, in the case shown in FIGS. 1B and 1D, the calculation formula uses the reading order n and the total number of pages P of the book as parameters. Since the total page number P can also be obtained from the number S of all recording sheets RM if the imposition number is known, the calculation formula Rc3 is a calculation formula using the reading order n and the total number (number of sheets) of recording sheets RM as parameters. It can also be said.
[0051]
For example, in the case of the imposition pattern shown in FIG. 2B, when the page order n of the recording sheet RM is an even number, that is, for back side printing, and the formation area is the lower left area ALD, the page order calculation formula Rc3 is , (4n-2). Further, in the case of the imposition pattern shown in FIG. 1B, when the page order n of the recording sheet RM is an even number, that is, for back side printing, and the formation area is the right area AR, the page order calculation formula Rc3 is (P−n + 1). However, the parameter P is the total number of pages.
[0052]
[Menu screen for imposition pattern registration]
FIG. 6 is an example of a menu screen for registering the imposition pattern. This menu screen W1 is displayed on the monitor of the restoration station 2. This menu screen W1 is roughly divided into four sub-windows.
[0053]
In the sub window SW1, an image in which the registered imposition pattern is represented is displayed. The area selected for imposition pattern registration is displayed differently from the other areas. For example, in the case of this figure, a frame is displayed around the selected area. The sub window SW2 displays an input box and a select box for setting the number of imposition pages, the direction of movement, the amount of movement, layout position, rotation information, front / back information, page number calculation formula, and trimming area. Further, the sub window SW3 is an area for collectively displaying the currently set imposition pattern information IMD.
[0054]
The sub window SW4 displays an input box for inputting a set name and command buttons for “new”, “load”, “register”, and “delete”. When the “new” button is clicked, all the data is blanked for setting the new imposition pattern information IMD. When the “load” button is clicked, imposition pattern information IMD corresponding to the set name inputted at that time is read. This is used when registering new imposition pattern information IMD based on the imposition pattern information IMD. When the “Register” button is clicked, various information that is currently input is registered as imposition pattern information IMD. When the “Delete” button is pressed, the imposition pattern information corresponding to the input set name is deleted.
[0055]
A plurality of imposition pattern information IMD can be sequentially registered using this menu screen W1. The plurality of registered imposition pattern information IMD are temporarily stored in the memory of the restoration station 2.
[0056]
[Restore processing routine]
FIG. 7 shows a control flow of a restoration processing routine for generating book data BD according to the present invention. Of course, this control flow is executed in the restoration station 2. When there are a plurality of recording sheets RM required for restoring the book data, instead of one, the recording sheets RM are rearranged in a predetermined order before executing this control flow. It is preferable. The predetermined order is the same as the order when normal printing is performed. This is because the reading order n is included as a variable parameter in the calculation formula used when determining the page order.
[0057]
First, in step ST1, when the operator instructs the start of the execution of the restoration processing routine, a variable n as the number of processed recording sheets RM is initialized to “1”. Subsequently, in step ST2, restoration processing conditions are set. The restoration process condition is set on the menu screen W2 shown in FIG. On the menu screen W2, the total number of pages, the restored page range, and the imposition pattern can be set. The total number of pages is the total number of pages of the book data BD to be restored. The restored page range is a range of pages for generating book data BD. The imposition pattern is for selecting imposition pattern information IMD of the imposition pattern of the recording sheet RM based on the set name Ra1 from those registered in advance. When the total number of pages and the restored page range are input and the imposition pattern is set and the “start” button is clicked, the process proceeds to the next step ST3, where substantial book data BD generation processing is started.
[0058]
Note that the number S of all the recording sheets RM can be obtained from the input total page number P and the set imposition page number of the imposition pattern. That is, the number S can be obtained from the equation {ROUNDUP (P / m)}. However, m is the number of imposition pages.
[0059]
Operations and functions of the processing steps after step ST3 will be described with reference to FIG. FIG. 9 shows the contents of various data when the book data BD is generated based on the recording sheet RM (see FIG. 9A) recorded by the imposition pattern shown in FIG.
[0060]
In step ST3, the nth recording sheet RM (1) is read and output as read data RD (n). Here, the read data RD (n) includes a plurality of page images PI applied to one recording sheet RM (n) as shown in FIG. 9B. When “n” is an odd number, it indicates a recording sheet RM for front side printing, and when “n” is an even number, it indicates a recording sheet RM for back side printing.
[0061]
Subsequently, in step ST4, the data is divided into a plurality of page data according to the imposition pattern information IMD set in step ST2. This division processing is performed based on the layout position Rb1, the front / back information Rc1, the trimming region Rc2, the rotation information Rb2, the node movement direction Ra3, and the node movement amount Ra4 of the imposition pattern information IMD. Basically, the read data RD is trimmed based on the trimming region Rc2 for each example layout position, and the page data PD corresponding to each layout position is cut out and output. Note that when the information regarding the throat is set, the trimming region Rc2 is corrected according to the throat movement direction Ra3 and the throat movement amount Ra4. As a result, the obtained page data PD is shown in FIG. Further, a rotation process is added based on the rotation information Rb2. As a result, the finally obtained page data PD is shown in FIG.
[0062]
In ST5, the page order is given to the divided page data PD according to the page order calculation formula Rc3. The page number is obtained by a calculation formula Rc3 using the number of processed sheets n, the total number of pages P, or the total number S of recording sheets RM as parameters, and this page number is assigned to the page data PD as a page order. FIG. 9E shows the page order assigned to each page data PD. For example, page order “1” is assigned to page data PD1 (1, 1), and page order “8” is assigned to page data PD1 (2, 1).
[0063]
In step ST6, the variable n is incremented by “1” for the processing of the next recording sheet RM. In step ST7, it is determined by comparing the variable n with the value of the total number of recording sheets S whether or not the processing has been completed for all recording sheets. If not completed, the process returns to step ST3, and the processing from step ST3 to step ST6 is repeated for the next recording sheet RM. When the processing for all the recording sheets RM is finished, the restoration processing routine is finished. Note that the processing order of the recording sheets RM is the same order as when normal printing is performed.
[0064]
In this way, a collection of page data in which page order is assigned to each page data is so-called book data BD. It should be noted that a collection of page data to which page order is assigned may be integrated into one file, or book data is generated by making each file separate to a separate file and storing them in a common directory. You may comprise as follows. Further, assigning a page order does not only mean assigning a page number to each page data but also includes sorting the page data in page order.
[0065]
[Other restoration processing routines]
FIG. 10 shows a control flow of another restoration processing routine for generating book data BD according to the present invention. The control flow shown in FIG. 10 differs from the control flow shown in FIG. 7 in the timing for assigning the page order to each page data. In the example shown in FIG. 7, the page order is assigned to each page data for each processing of one recording sheet RM. However, in the example shown in FIG. After the reading and page division processing ends, the page order is assigned collectively.
[0066]
Steps ST11 to ST14 are the same as in the case of FIG. In step ST15, the variable n is incremented by “1” for processing the next recording sheet RM. Subsequently, in step ST16, it is determined by comparing the value of the variable n and the total number of recording sheets S whether or not the processing has been completed for all the recording sheets RM. If not completed, the process returns to step ST13, and the processes of steps ST13 to ST15 are repeated. When the processing for all the recording sheets RM is completed, the process proceeds to step ST17, and a page order is assigned to each page data. Note that the processing related to the assignment of the page order is the same as the processing in step ST5 shown in FIG.
[0067]
[Use of restored book data BD]
The book data BD restored in this way is transmitted to the controller 3 that also functions as a server. Subsequently, the book data BD is edited and compiled by the editing station 4 and further impositioned with a new imposition pattern. The edited / edited and impositioned book data BD is printed in page order by the printer 5 via the controller 3.
