Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an imposition data creating apparatus, and more particularly to an imposition data creating apparatus for creating imposition data composed of a plurality of page data arranged corresponding to imposition on a master plate film. .

[0002]

2. Description of the Related Art When a printed matter such as a book is produced, page data of a plurality of pages are recorded at predetermined positions on one original film, and a printing plate is produced using this original film. For example, when performing bookbinding in units of 16 pages, each page is printed in 2 rows and 4 lines on the front and back sides of one sheet, and this one sheet is folded into eight to perform bookbinding.

In this case, one master film has 8
Imposition of page data for pages is required. Conventionally, when performing imposition, an operator pastes the page data of each page. On the other hand, recently, it is possible to automatically obtain a film for plate making from the data of character images using a computer. When such a system is used, the page data of each page is arranged, the imposition data is automatically created, and the imposition can be performed without the intervention of the operator.

[0004]

When performing the above-described automatic imposition, if the page data of each page is prepared in advance, the imposition can be performed without any problem. However, in the actual printing and binding process, the page data of all pages are often not complete. For example, in the advertisement page, the original film itself may be supplied instead of the original. In such a case, it is necessary to recreate page data from the provided original film. In other words, a printed matter is created from the provided original film through each process such as normal printing plate making, the printed matter is read by a scanner to create page data, and the imposition data is combined with the already prepared page data. It has to be created and requires a lot of trouble. Therefore, in such a case, the original film corresponding to each page data is separately created without newly creating the imposition data, and the operator pastes the original film separately provided and the original film is provided. A printing plate is prepared by preparing a master plate film collected on a single plate, or performing multiple printing of the master plate film using a light-shielding mask corresponding to each of the master plate films prepared separately. However, it is necessary to perform the sticking work a plurality of times when preparing a master plate film collected in one sheet, and when performing multiple baking of the master plate film, it is necessary to prepare a light-shielding mask corresponding to each master film. I won't.

An object of the present invention is to make it possible to easily create imposition data for page data that is complete even if the page data for each page is not available.

[0006]

An imposition data creating apparatus according to the present invention is an apparatus for creating imposition data composed of a plurality of page data arranged corresponding to an imposition on an original film. Instructing means for instructing imposition information for imposing the page data of on the original film,
And data arranging means. When the page data corresponding to the page number specified by the imposition information is prepared, the data arranging unit arranges the corresponding page data according to the imposition information, and when the page data is not prepared, Imposition data is created by arranging dummy data instead of page data according to the imposition information.

[0007]

In the imposition data creating apparatus according to the present invention, the plurality of page data created by the page data creating means are arranged by the data arranging means in accordance with the imposition information specified by the instructing means. create. At this time, when the page data corresponding to the page number designated by the imposition information is prepared, the data arrangement means arranges the corresponding page data according to the imposition information, and when the page data is not prepared. The imposition data is created by arranging dummy data according to the imposition information instead of page data.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the structure of a master film production system including an imposition data production apparatus according to an embodiment of the present invention. This system includes a page data creation device 1 for creating page data of each page and page layout data for determining at which position of the original film the page data created by the page data creation device 1 is to be placed. The data creating device 7 includes a page data arranging device 2 for creating and creating imposition data based on the page layout data, a data converting device 3, and an output device 4. A scanner 5 for inputting pattern information and a character input device 6 for inputting character information are connected to the page data creation device 1. Page data creation device 1
Is a DTP (desk top publishing) device, word processor device, or the like, which is a known microcomputer, and corresponding page data is created in association with the page number. The page data of each page created by the page data creation device 1 is the imposition data arranged by the page data layout device 2 according to the layout of the original film based on the page layout data, and the created surface The additional data is input to the data conversion device 3. The data conversion device 3 is a device for converting the input imposition data into raster data. The data converted by the data converter 3 is input to the output device 4. An original film is mounted on the output device 4, and an image based on the data from the data conversion device 3 is recorded on the original film.

The page data layout device 2 has a processing section 10 as shown in FIG. The processing unit 10 is a CP
It includes a microcomputer including U, RAM, ROM and the like. A storage unit 11, a CRT 12 as a display device, a floppy disk drive 13, and a keyboard 14 are connected to the processing unit 10. Further, the processing unit 10 is connected to external devices such as the page data creation device 1 and the data conversion device 3.

Next, the processing unit 1 of the page data layout device 2
The control operation at 0 will be described with reference to the flowcharts shown in FIGS. Here, as shown in FIG. 6, an example of creating a master film in the case of printing 16 pages of information on the front and back of one printing sheet will be described. The numerical values shown on the printing paper 20 of FIG. 6 are page numbers, and the orientation of the page numbers indicates the vertical orientation of the page. In this example, pages 5-12, 1-4 and 13-
The information on page 16 indicates that the vertical direction is opposite.

When the apparatus is activated, first, in step S1 of FIG. 3, initialization is performed. In this initial setting, the page number of each allocation position of the original film, which will be described later, is set to "0", and the vertical directions are all set to the upward direction. Further, the number "n" indicating the allocation position is set to "1". In another embodiment described later, the page number "m" is set to "1". Next, in step S2, a menu for processing is displayed on the CRT 12. Here, various processing menus are displayed. In step S3, it is determined whether the menu for designating the information for imposition has been selected from the processing menus. Here, the information for imposition is
Information about the size of the page, whether the signature is right or left, whether it is a bag or a bag, how to bind, throat, grip size, registration marks, page numbers, etc. Step S
In step 4, it is determined whether or not a processing menu for creating page layout data has been selected. Further, in step S5, it is determined whether or not the processing menu for outputting the data is selected. Further, in step S6, it is determined whether or not another processing menu is selected.

When the processing menu for designating the information for imposition is selected, the process proceeds from step S3 to step S10. In step S10, the information for imposition specified by the operator is fetched. Here, for example, when creating a printing sheet as shown in FIG. 6, information such as “8-fold right-opening” is designated. When the processing menu for creating page layout data is selected, the process proceeds from step S4 to step S11. In step S11, a page layout data creation process described later is executed. If the processing menu for data output is selected, step S
The process proceeds from step 5 to step S12. In step S12, imposition data is created in which the page data of each page created by the page data creation device 1 is arranged based on the page layout data created in step S11.
The imposition data is output to the data conversion device 3. At this time, the page data arranging device 2 is prepared in advance with a bitmap memory corresponding to the size of the original film, and the page data is arranged on this bitmap memory according to the page arrangement data. When all the arrangements are completed, the data on the bit map memory is sequentially read and is output to the data conversion device 3 as imposition data.
The original film may be divided into a plurality of sizes, and the bitmap memory may be divided into a plurality of sizes and output to the data conversion device 3. The data converter 3 outputs the imposition data to the original film set on the output machine 4 at the assigned positions and orientations as shown in FIG. 6 based on these information.

Further, when a menu for performing another process is selected, the process proceeds from step S6 to step S13, the corresponding process is executed, and the process returns to step S2.
FIG. 4 shows the page layout data creation process in step S11. In this page layout data creation process, first in step S20, a pattern corresponding to the information for imposition as shown in FIG. 7 is displayed. Here, in the pattern 21 shown in FIG. 7, the number (“0” in FIG. 7) in the upper display area 21a at each page allocation position indicates the page number, and the arrow 21b below the arrow indicates the vertical direction of the page. Shows.

In step S21, the allocation position "n =
Wait for input to specify which page to allocate in (1). In the example shown in FIG. 6, the numeral “5” is set here.
Is entered. In step S22, the page number "5" input in step S21 is fetched. Next, in step S23, it is determined whether or not the page data of the designated page (5 pages) has already been created by the page data creation device 1. It should be noted that this determination is made by the page number provided in association with each page data. If it has been created, the process proceeds to step S24, and page layout data for laying out the page data of the fifth page at the allocation position "1" is created. Next, in step S25, the input of the vertical direction of the fifth page assigned to the assigned position “1” is waited for. In the initial state, all are set to face up as shown in FIG. 7, but when the reverse direction is designated here, the direction code indicating the reverse direction is added in step S26. At the same time, when the reverse direction is designated, the direction of the arrow in the pattern display is changed to the reverse direction.
Next, in step S27, the number n indicating the allocation position is incremented and the process proceeds to step S28. In step S28, the allocation position n is preset to N
("8" in the example shown in FIG. 7) is determined. If not exceeded, the process proceeds from step S28 to step S29, and it is determined whether or not a key for ending this process is pressed. If it has not been pressed, the process returns to step S21, and page allocation processing relating to the next allocation position "2" is performed in the same manner as described above. If the allocation position n exceeds N (in the example shown in FIGS. 6 and 7, it exceeds “8”), the process proceeds from step S28 to step S30. In step S30, the allocation position n is reset to "1" again, and the processes after step S21 are repeatedly executed.

By repeating the imposition processing at each allocation position in this manner, the pattern display becomes a display as shown in FIG. 7 (B). The display shown in FIG. 7 (B) corresponds to the arrangement of the table of the printed matter 20 in FIG. 6 (A). Here, for example, if page 13 shown in FIG. 6 is an advertisement page and a film is supplied separately, the page data creation device 1 cannot create the page data for the 13 pages. In this case, the page number "13" at the allocation position "6" is fetched in step S22, but in step S23, it is determined that the page data of the designated page has not been created, and step S23 is executed.
It moves from 23 to step S31. This step S3
At 1, the dummy data setting process is executed.

FIG. 5 shows the dummy data setting process.
In this case, in step S40, it is determined whether or not the dummy data is used as the light-shielding mask forming data, in step S41, it is determined whether or not the dummy data is used as the light-transmitting area forming data, and then in step S42. In, it is determined whether to use other data. Here, as the other data, for example, information such as the type of document assigned to page 13 is selected as the data.

When the shading mask forming data is selected as the dummy data, the process proceeds from step S40 to step S43, and black data is created in step S43. Then, in step S44, the created data is stored as page data to be arranged at the corresponding allocation position. An original film F1 created using such dummy data is shown in FIG. In this example, the light-shielding mask SM is formed at the allocation position of page 13.

When the data for forming the light-transmitting area is selected as the dummy data, the process proceeds from step S41 to step S45. In step S45, it is determined whether or not the register mark is recorded. Step S4
If YES is determined in step 5, the process proceeds to step S46, data for the register mark is created and stored in the same manner as described above. On the other hand, if NO is determined in step S44, no particular data is created. That is, in this case, since nothing is output as page data of page 13, page 13 becomes a light-transmitting area in the original film. When blank data (translucent area) and register marks are selected as dummy data, a master film F2 as shown in FIG. 9 is created. Here, the allocation position of page 13 is the light-transmissive area P, and the register mark R is recorded in a part thereof. If other data is selected, other data is created in step S47 and stored in step S49.

When imposition data is created in units of 16 pages as in this embodiment, front and back original film films corresponding to the printing paper shown in FIG. 6 are created. Next, a procedure for making a printing plate using the original film obtained as described above will be described. First, using FIG.
A procedure for making a printing plate when a light-shielding mask is formed on a part of the original film will be described.

In step P1, the original film F1 having the light-shielding mask M partially formed as described above is prepared.
Next, in step P2, as shown in FIG. 11, first printing is performed on the printing plate 30 using the original film F1 obtained in step P1. The printing plate 30 printed in step P2 is as shown in FIG. 12, and only the assigned position of the 13th page is unexposed.

Next, in step P3, as shown in FIG.
The printing plate 30 printed in the step P2 using the 13th page separately supplied, for example, the advertising film F3.
Overprint on. Here, in order to mask the portion that has already been baked, a mask 31 having a transparent hole in part is used. Note that the mask 31 is not necessary when printing is performed by a printing device having an automatic mask device. In this way, the printing plate 30 as shown in FIG. 14 is obtained. After that, development is performed in step P4, and the creation of the printing plate is completed.

In creating the printing plate, it is necessary to print a size equal to the size of the printing plate and to print a small size original film such as the advertising film F3 at an accurate position. In this case, it is necessary to use both plate making machines of the incinerator and the plate making machine.
With the belt transfer type printing machine described in Japanese Patent No. 3,
Both printings can be performed by one plate-making machine.

Next, with reference to FIG. 15, a procedure for making a printing plate using the original film F2 in which a light-transmitting region is formed in a part of the original film will be described. First, the process P10
Then, as described above, the original film F2 in which the translucent region P is partially formed is prepared. Next, in process P11, the separately supplied 13th page advertisement film is attached to the transparent region P of the original film. Here, the register mark R for registration is recorded on the original film F2 and the separately supplied film, so that the sticking can be performed easily and accurately.

Next, in step P12, baking is performed using the original film obtained as described above, and thereafter,
In step P13, development processing is performed to create a printing plate as shown in FIG. In the present embodiment as described above, even when the page data includes an unprepared page, the data for one original plate film can be output while automatically imposing. Further, by assigning the data for forming the light-shielding mask to the data for which the page data is not prepared as the dummy data, it is possible to print other page data without using another light-shielding mask. Further, by assigning the light-transmitting area forming data as dummy data, a separately supplied film can be attached to a portion of the page data where the page data is not prepared to form a single original film. Further, in this case, since the ink is not deposited on the light transmitting area portion at the time of color calibration, color calibration can be performed only on the other portion except the portion. Further, by recording the register mark in the light transmitting area portion, the sticking can be performed accurately and easily.

[Other Embodiments] In the above-described embodiment, the page allocation position is designated for each page data. However, the page data arrangement is performed only by inputting the first page number in units of a plurality of pages. Alternatively, dummy data arrangement may be performed. FIG. 16 shows another example of the page layout data creation process in step S11 of FIG.

In this page layout data creation process, first, in step S50, a layout for arranging page data is selected. Here, the layout is different from the pattern 21 shown in FIG. 7 in that not only the arrangement position of each page data, but also the vertical direction of the page data and 5 in FIG.
The order of page data such as 12, 9, 8 ...

In step S51, the first page data
Enter the page number and convert this input number to m. In the example shown in FIG. 6, since the imposition data is created in units of 16 pages, the page number m to be arranged is determined by inputting the first page number for each unit. For example, 1
When imposing 6 pages at a time, 1, 17, 33, 49, etc. may be considered as the first page number. When 17 is entered, imposition data to be created includes pages 17 to 3
Arrangement of each data is performed as one unit up to two pages.
An error may be displayed when the first page number that does not match the layout selected in step S50 is input. Next, in step S52, it is determined whether the page data of page number m is prepared. Step S if page data is prepared
53, the page layout data is created according to the layout selected in step S50
Move to 54. On the other hand, if it is determined in step S52 that the page data has not been prepared, step S
At 58, the missing page flag that indicates missing page data is turned on. In step S59, the page number of the missing page data, the layout position of the page data, and the like are stored, and the process proceeds to step S54. In step S54, the number m indicating the page number is incremented.

Next, in step S55, it is determined whether or not the page number m exceeds a predetermined value M. Here, the predetermined value M
Represents the page number m + 15 in the example shown in FIG. 6, and it is determined whether or not the processing in units of 16 pages has been completed. If not exceeded, the processing from step S52 is repeated. If it exceeds the limit, the process proceeds from step S55 to step S56, and it is determined whether or not there is a missing page. If there is no missing page, the process proceeds to step S57, and it is determined whether or not a key for ending this process is pressed. If it has not been pressed, the process returns to step S51, and the page layout data creation process is performed in the same manner as above. On the other hand, if it is determined in step S56 that there is a missing page, dummy data setting processing, which will be described later, is executed in step S60. When the dummy data setting process is completed, the missing page flag is turned off in step S61, and the process proceeds to step S57.

FIG. 17 shows the dummy data setting process. In this case, first, in step S70, the missing page is displayed on the CRT 12. Here, the missing page number is displayed. In step S71, various dummy data such as data for forming a light-shielding mask, which is created in advance and stored in the page data creating device 1 or the page data arranging device 2, is selected according to an instruction from the operator. Next, in step S72, the selected dummy data is stored as page data to be arranged on the missing page.
Then, in step S73, it is determined whether or not the dummy data setting process for all the missing pages has been completed. If not completed, the processing from step S70 is repeatedly executed.

By performing the above processing, the layout of page data and the layout of dummy data can be automatically performed only by inputting the first page number.

[0032]

As described above, according to the present invention, when the imposition data is created, if the page data is not prepared, the dummy data is arranged instead of the page data. Even if they are not arranged, it is possible to easily create imposition data for the page data that are arranged.

By creating imposition data for the complete page data and outputting the imposition data to the original film, it is possible to accurately and easily carry out the post-working work and baking work.
