Description

The present invention is a method for generating print data for variable printing and software for generating print data.

Printing while changing the contents of printed matter one by one is generally called variable printing. Digital printing machines used in variable printing are mass-produced and are therefore speeded up. Depending on the model, A4 standard paper can be printed at a speed of 30 sheets or more per minute. For example, in the case of a general ID card size, 10 sheets can be arranged on A4 standard paper, so that 300 ID cards can be printed per minute in terms of printing capacity.

If variable printing is performed at a speed of 300 sheets per minute, it is desirable to generate printing data to be given to the digital printing machine at a speed of 300 sheets per minute or more. That is, in order to take advantage of the high speed of the digital printing machine, it is necessary to generate printing data for each print in 0.2 seconds or less. On the contrary, if it takes more than 0.2 seconds to generate print data, it causes a decrease in productivity.

As described above, in order to maintain the high speed of the digital printing machine in variable printing, it is required to generate printing data in a time shorter than the printing ability.

Generally, when variable printing is performed, commercially available automatic typesetting software is used to generate printing data.

In FIG. 1, the print data 1a, 1b, and 1c for variable printing are a PDF format file (Non-Patent Document 1) or a PDF / X format file that is a subset of PDF (Non-Patent Document 2 and Non-Patent Document 3). Is widely used.

When generating print data using commercially available automatic typesetting software 2, images and characters are inserted into the image area 4 and the character area 5 of the layout data 3 according to the information recorded in the database.

Here, the degree of freedom in the design of the layout data 3 is limited to the functions of the automatic typesetting software 2. The fact is that there is no commercially available automatic typesetting software that can handle designs with a high degree of freedom, such as arranging characters along a free curve. The color space of the image that can be inserted also depends on the function of the automatic typesetting software 2. For example, it is often limited to general-purpose images such as RGB color and CMYK color, and there is no one that can handle other color spaces such as binary (monochrome 2 gradation) and spot color (for example, corporate color) images. ..

FIG. 2 shows a procedure for generating layout data using general automatic typesetting software.

As step S101, the database prepared in advance is read. For example, personal information is recorded in this database.

The page size is set in step S102.

As step S103, an image area is arranged, and as step S104, attributes such as a reference destination, an insertion position, an enlargement ratio, and an angle of an image file are set.

In step S105, image insertion conditions, such as fixed or variable conditions, are set. When the image is variable, the field information of the database is specified in the insertion condition, for example, as the reference destination of the image file. The procedure of steps S103, S104, and S105 is repeated for the number of image areas.

As step S106, a character area is arranged, and as step S107, attributes such as a character insertion position, a typeface, a set direction, a size, and a color are set.

In step S108, character insertion conditions, such as fixed or variable conditions, are set. When the character is variable, for example, the field information of the database is specified as the reference destination of the character in the insertion condition. The procedure of steps S106, S107, and S108 is repeated for the number of character areas.

As step S109, the created layout data is stored in the storage unit.

As described above, in steps S103 to S105 and S106 to S108, the procedure for inserting images and characters is repeated for the number of image areas and character areas arranged in the layout data, so that the more complicated the design, the more work. It takes time.

FIG. 3 shows a procedure for generating print data by performing typesetting processing on the created layout data using general automatic typesetting software.

As step S201, layout data is created according to the procedure shown in FIG.

During steps S202 and S210, the processes of steps S203 to S209 described later are repeated for the number of record information in the database.

As step S203, the layout data stored in the storage unit is read.

As step S204, an image is inserted into the image area arranged in the layout data.

As step S205, the attribute set in the image area is applied to the inserted image. The processing of steps S204 and S205 is repeated for the number of image areas.

As step S206, a character is inserted into the character area arranged in the layout data.

As step S207, the attribute set in the character area is applied to the inserted character. The processing of steps S206 and S207 is repeated for the number of character areas.

As step S208, print data incorporating images and characters is generated. The process from step S204 to step S208 corresponds to the typesetting process.

As step S209, print data is stored in the storage unit.

The automatic typesetting software executes arithmetic processing for generating print data while performing typesetting processing for inserting images and characters into predetermined positions based on layout data. That is, each time the typesetting process of the print data is performed, a code in which the attributes of the image and characters are described (hereinafter referred to as "property information") and a code in which the contents of the images and characters are described as continuous data. (Hereinafter referred to as "stream information") is incorporated into the print data.

In the case of print data used for general variable printing, in most cases, the attributes that determine the appearance of the design, that is, the property information, do not change even if the contents of the image or characters change. However, in the automatic typesetting software, the same property information is repeatedly described for the print data every time the typesetting process is performed. As a result, it took a lot of time for the arithmetic processing.

Further, the design proposal of the printed matter is often created by using design software such as Adobe Illustrator (registered trademark). Therefore, even if variable printing is a prerequisite, it is rare to create design, that is, layout data using automatic typesetting software from the beginning.

Therefore, when creating print data for variable printing, it is common to create a design proposal using design software, and then create layout data so that it can be traced by automatic typesetting software as a sketch. Procedure.

In this way, after creating a design proposal first, the layout data is created as if the design was recreated using automatic typesetting software, using the design proposal as a sketch, so duplicate work is repeated at the design stage. In some cases, workability was low.

In addition, compared to the design software normally used by designers, the automatic typesetting software had a much lower degree of freedom and expressiveness in design.
For example, in design software, it is possible to freely arrange the design, such as applying a clipping mask to an image, arranging characters along a free curve, and arranging them in a complicated layer structure. , The automatic typesetting software could not handle all such design expressions.

In this way, there is a difference in the degree of freedom in design between the design software and the automatic typesetting software, and it is often not possible to directly reflect the highly flexible design expression created by the design software in the automatic typesetting software. there were.

As a conventional technique related to automatic typesetting, there are those described in, for example, Japanese Patent Application Laid-Open No. 2000-29875 and Japanese Patent No. 4834919.

Japanese Unexamined Patent Publication No. 2000-29875 Japanese Patent No. 4834919 PDF Reference sixth edition ISO 15930-1: 2001 Graphic technology-Prepress digital data exchange-Use of PDF- ISO 15930-7: 2010 Graphic technology-Prepress digital data exchange PDF-

In the conventional technology as described in Patent Document 1 and Patent Document 2, for example, using an automatic typesetting system or automatic typesetting software, a process of generating a condition in a predetermined area and inserting an image or a character is performed. Depending on the design, it takes longer than the printing capacity of the digital printing machine to generate printing data for variable printing, and there is a problem that the productivity is low.

In addition, after the design proposal was created by the design software, the layout data was created as if the design was recreated using the automatic typesetting software using this design proposal as a sketch, so the workability was low.

Furthermore, since the commercially available automatic typesetting software has a lower degree of freedom in design than the commercially available design software, it has not been possible to realize all the design expressions by the design software.

In view of the above circumstances, the present invention provides a method for generating print data for variable printing and software for generating print data, which can improve productivity and workability and can express a design with a high degree of freedom. The purpose is to provide.

The present invention uses a device including a storage unit and a processing unit and software having a data input function, an arithmetic processing function, and a data output function, and an image and / or an image stored in the storage unit by the data input function. A step of inputting source data including characters, a step of inputting setting data stored in the storage unit by the data input function, and a database stored in the storage unit by the data input function are input. And the first stream information of the image and / or the character included in the source data while maintaining the property information of the image and / or the character included in the source data by the arithmetic processing function. Is replaced with the second stream information obtained by converting the image and / or the character into stream information according to the information recorded in the database according to the setting data, and the step of generating the print data. Then, the print data for variable printing is generated at high speed by the step of storing the print data generated by the data output function in the storage unit.

According to the method for generating print data and the software for generating print data of the present invention, a method for replacing stream information with new stream information while maintaining property information of images and characters contained in the source data. Since the print data is created in, workability and productivity are improved, print data for variable printing can be generated at high speed, and the highly flexible design expression of the source data can be maintained.

(Embodiment 1)
Hereinafter, a method for generating print data according to an embodiment of the present invention will be described with reference to the drawings.

Designers usually embody the design drawn in their head as design data 7 using commercially available design software 6, as shown in FIG. The design software 6 can freely arrange the design, such as applying a clipping mask to an image, arranging characters along a free curve, and arranging them in a complicated layer structure. It should be noted that these functions provide a design expression with a higher degree of freedom than commercially available automatic typesetting software.

In the commercially available design software 6, the design data 7 can be stored in the storage unit as, for example, a PDF format file 8.

Therefore, as shown in FIG. 5, the PDF format file 8 is used as a template (hereinafter referred to as “source data”), and only the stream information of the variable information is replaced to print data for variable printing. Create 1a, 1b, and 1c.

Here, FIG. 6 shows an example of stream information and property information of images and characters.

In principle, the elements that make up the print data are considered to be classified into either images or characters. Images include raster images represented by bitmaps and vector images represented as figures and line drawings. Some characters are represented by character codes such as ASCII code and HEX code.

Property information common to images and characters includes placement coordinates, size, enlargement ratio, ratio, angle, and the like. Property information peculiar to a raster image includes the number of pixels, color depth, color space, and the like. Property information unique to vector images includes color (fill and line), line width, and the like. Property information specific to characters includes typeface, color, character spacing, line spacing, and the like.

In the present embodiment, the property information is maintained unchanged and only the stream information is replaced to create print data for variable printing. This makes it possible to generate print data at a higher speed than in the past, where it was necessary to typeset not only stream information but also property information for each case using automatic typesetting software, and the design software has it. The degree of design freedom can be maintained.

For example, as shown in FIG. 7, in the PDF format file 8, the source data 9 in which the image 10 to be variable information is changed to “black” and the character 11 to be variable information is changed to “0” is used. It should be noted that this change is not necessarily a procedure to be performed in this embodiment, and the PDF format file 8 can be used as the source data 9.

Such source data 9 is read from the storage unit, and as shown in FIG. 8, desired stream information, that is, the contents of the image 10 and the character 11 are described for the variable information image 10 and the variable information character 11. By substituting the code, print data 1a, 1b, and 1c are generated.

Instead of inserting and arranging images and characters using automatic typesetting software as in the past, the property information of the images 10 and characters 11 that have already been arranged in the source data 9, that is, the attributes of the images and characters The written code is maintained untouched, and only the stream information, that is, the code in which the content of the image or character is described is replaced to generate the print data 1a, 1b, 1c, so that the typesetting process is unnecessary. Is.

Here, for example, the structure of the PDF format file used as the source data 9 is defined by the PDF Reference sixth edition of Non-Patent Document 1, and as shown in FIG. 9, the header 12a and the body 12b are defined. , Cross-reference table 12c, Trailer 12d. Of these, the property information and stream information of images and characters are all described in the area called the body 12b.

The body 12b is composed of an aggregate of objects 13a, 13b, and 13c as shown in FIG. As shown in FIG. 11, the property information and stream information of the image are described in an object called a graphic object 14, and the property information and stream information of characters are text objects (text objects). It is described in an object called Text object) 15.

As shown in FIG. 12, the stream information is described in the portion 16 surrounded by two keywords, the stream (stream) to the end stream (endstream) in the object 13.

For the image, for example, as shown in FIG. 13, in the graphic object 14, the stream information 17a in which the code representing the density value of the image is described is replaced with the new stream information 17b, and the content of the image is changed. do. When replacing the stream information of an image, in principle, the amount of stream information, specifically, the elements constituting the pixels of the image are not changed. Further, the property information in which the arrangement coordinates, size, color space, etc. of the image are described is not changed as described above. Therefore, the design of the source data 9 can be maintained as it is.

For characters, for example, as shown in FIG. 14, in a text object, the stream information 17c in which a code representing a character is described is replaced with new stream information 17d to change the content of the character. When replacing the stream information of characters, the amount of stream information, specifically, the number of characters may be changed, unlike the case of an image.

However, the property information in which the arrangement coordinates, typeface, size, color, etc. of the characters are described is not changed in the same manner as the property information of the image. Therefore, the design of the source data 9 can be maintained as it is.

By the way, as shown in FIG. 15, a byte length (Length) 18 indicating the amount of information is described in the graphic object 14 and the text object 15 depending on the stream information 17 of images and characters. The byte length 18 indicating the amount of information in the stream information 17 varies depending on the compression method or the like in the case of an image and the number of characters or the like in the case of characters. Therefore, if the byte length 18 is increased or decreased by replacing the stream information 17a and 17c with the stream information 17b and 17d, the byte length 18 described is described for the purpose of satisfying the specifications of the PDF format file. You need to change the value of.

At the end of the PDF format file, as shown in FIG. 16, a cross-reference table (hereinafter referred to as "cross-reference table") in which the start position of each object 13, that is, the number of bytes from the beginning to the beginning of the object is listed is listed. ) 19 is described. This cross-reference table 19 corresponds to a so-called table of contents, and when the byte length 18 of an image or a character fluctuates, the value fluctuates accordingly.

For example, if the byte length 18 is increased or decreased by replacing the stream information 17a and 17c with the stream information 17b and 17d as described above, the object 13 is used for the purpose of satisfying the specifications of the PDF format file. It is necessary to change the start position 20 of the later object 13 and the start position 21 of the cross-reference table.

In the example shown in FIG. 16, it is assumed that the byte length 18 of the seventh object 13 is increased by 512 bytes. In such a case, 512 bytes are added to the start position 20 of the eighth and subsequent objects 13 and the start position 21 of the cross-reference table.

FIG. 17 shows a configuration of an apparatus and software for generating printing data according to an embodiment of the present invention.

This device includes a storage unit 101 and a processing unit 102, and the processing unit 102 includes software having a data input function 103, an arithmetic processing function 104, and a data output function 105. The storage unit 101 corresponds to a hard disk drive or RAM in a computer, and the processing unit 102 corresponds to a CPU in a computer.

The storage unit 101 stores source data such as a PDF format file necessary for creating print data. As the source data, for example, as will be described later with reference to FIG. 18, a PDF format file created by using commercially available design software may be used as the source data.

The storage unit 101 also stores a database format file or the like (hereinafter referred to as a “database”) necessary for creating print data. In this database, for example, information such as a name, gender, and age indicating each individual is recorded.

The data input function 103 inputs the source data stored in the storage unit 101, the database, and the setting data described later.

The arithmetic processing function 104 replaces the first stream information of the image and the character contained in the source data with the second stream information obtained by converting the image and the character into the stream information according to the information recorded in the database. .. On the other hand, print data is generated while maintaining the property information included in the source data.

The data output function 105 stores the print data generated by the arithmetic processing function 104 in the storage unit 101.

The flowchart of FIG. 18 shows a procedure for creating source data using commercially available design software.

The page size is set in step S301.

The image is arranged in step S302, and attributes such as the arrangement coordinates, size, enlargement ratio, ratio, and angle of the image are applied to the image in step S303. The procedure of steps S302 and S303 is repeated for the number of images.

Characters are arranged as step S304, and attributes such as character arrangement coordinates, typeface, color, character spacing, and line spacing are applied to the characters as step S305. The procedure of steps S304 and S305 is repeated for the number of characters. In principle, the number of characters in this case indicates the number of character strings, not the number of characters.

As step S306, the created source data is stored in the storage unit 101.

The flowchart of FIG. 19 shows a procedure for creating setting data based on the source data. The setting data is data in which replacement conditions such as a start position and an end position of stream information of images and characters to be replaced included in the source data are recorded.

As step S401, the source data stored in the storage unit 101 is read.

In step S402, the stream information of the image to be replaced is searched from the source data.

In step S403, a replacement condition including the start position of the stream information of the searched image, specifically, the number of bytes from the beginning of the source data, the end position, the encoding method, and the like is set. The procedure of steps S402 and S403 is repeated for the number of images to be replaced.

In step S404, the stream information of the character to be replaced is searched from the source data.

In step S405, a replacement condition including a start position, an end position, an encoding method, and the like of the stream information of the searched characters is set. The procedure of steps S404 and S405 is repeated for the number of characters to be replaced.

As step S406, the setting data is stored in the storage unit 101. Alternatively, the setting data may be described directly in the syntax of the software program.

FIG. 20 shows an example of a database. Similar to a general database, the horizontal axis may be field information (name, gender, age, etc.), and the vertical axis may be record information (person 1, person 2, ...). The value of the field information shown in this figure is a value to be used as an index in software, for example.

FIG. 21 shows an example of setting data. The horizontal axis may be the type of character or image, the start position and end position of stream information, the encoding method, and the like, and the vertical axis may be the number of images and characters to be replaced. When such setting data is stored in the storage unit 101 as a text format file, it may be described in, for example, a CSV format file 22 as shown in FIG.

The flowchart of FIG. 22 shows a procedure for creating print data according to the present embodiment.

As step S501, the data input function 103 reads the source data stored in the storage unit 101.

As step S502, the data input function 103 reads the setting data stored in the storage unit 101.

As step S503, the data input function 103 reads the database stored in the storage unit 101.

The process from step S504 to step S508 is repeated for the number of record information in the database.

First, in step S505, the arithmetic processing function 104 streams the first stream information of the image and the character to be replaced contained in the source data according to the setting data and the image and the character according to the information recorded in the database. Replace with the second stream information converted to.

As step S506, the arithmetic processing function 104 updates the byte length and the cross-reference table value that have changed due to the replacement of the stream information.

In step S507, the data output function 105 stores the print data generated by the arithmetic processing function 104 in the storage unit 101.

(Embodiment 2)
Hereinafter, a method for generating print data according to the second embodiment of the present invention will be described with reference to the drawings.

Source data may include a given typeface. The character shape information of the typeface included in the source data is described in the code in the PDF format file as font data. When a PDF / X format file is used as the source data, it is necessary to include the font data for the purpose of satisfying the specifications.

When creating the source data of a PDF format file or PDF / X format file using commercially available design software, for example, when saving the source data, include the font data (in the case of Adobe Illustrator®, embedding the font). You can select the presence or absence of.

Since the attribute of the typeface included in the source data is one of the property information, it is not necessary to change it with the replacement of the stream information.

However, as for the font data, only the font data of the characters arranged in the source data may be described. Therefore, when changing to unused characters or adding unused characters by replacing the stream information. In that case, it is necessary to replace or add the font data.

As for the font data, for example, as shown in FIG. 23, the font data 24a and 24b are described as one of the stream information in the text object.

When adding characters that are not used in the source data, for example, "M and I" by replacing the character stream information 23a with 23b, add the font data 24b of "M and I" to the font data 24a of the source data. do. In principle, the font data 24b uses the same typeface as the font data 24a in order to maintain the designability of the source data.

The flowchart of FIG. 24 shows a procedure for creating print data according to the second embodiment.

Steps S601 to S603 and S604 to S605 are the same processes as steps S501 to S503 and S504 to S505 of the first embodiment described above.

As step S606, the arithmetic processing function 104 replaces or adds the font data of the characters changed or added in accordance with the replacement of the stream information in step S605.

As step S607, the arithmetic processing function 104 updates the byte length and the cross-reference table value that have changed due to the replacement of stream information and the replacement or addition of font data.

In step S608, the data output function 105 stores the print data generated by the arithmetic processing function 104 in the storage unit 101.

(Embodiment 3)
Hereinafter, a method for generating print data according to the third embodiment of the present invention will be described with reference to the drawings.

In the first embodiment and the second embodiment, the property information of the source data is maintained unchanged in order to improve the speed of generating the print data, but in the third embodiment, the appearance of the design is maintained or the design is maintained. In addition to the replacement of stream information, the case of replacing property information will be described for the purpose of expanding the variety of.

For example, character property information includes placement coordinates. When arranging characters in the source data using commercially available design software, left alignment, center alignment, right alignment, etc. can be selected as the paragraph of the characters, but the PDF format file is limited to left alignment.

Not only in variable printing, but also in printed matter, the variety of character alignment is an important design element. Therefore, if the number of characters or the width of the characters fluctuates due to the replacement of the stream information of the characters, by changing the arrangement coordinates that are the property information, the center alignment, right alignment, etc. are reproduced in a pseudo manner, that is, in the human appearance. It is desirable to do.

In the example shown in FIG. 25, the character "0" designed for center alignment is replaced with "AB", but as described above, in the PDF format file, both characters are left alignment. be. In such a case, by changing the arrangement coordinates of "AB", the center alignment can be reproduced in a pseudo manner. In FIG. 25, the arrangement coordinate 26a, which is the property information of the character, is replaced with the arrangement coordinate 26b as an example of the case where the number of characters is increased or decreased due to the replacement of the character stream information 25a with the stream information 25b.

The flowchart of FIG. 26 shows a procedure for creating print data according to the third embodiment.

Steps S701 to S703 and S704 to S705 are the same processes as steps S501 to S503 and S504 to S505 of the first embodiment described above.

As step S706, the arithmetic processing function 104 replaces the property information to be changed with the replacement of the stream information in step S705.

As step S707, the arithmetic processing function 104 updates the byte length and the cross-reference table value that have changed due to the replacement of the stream information and the replacement of the property information.

In step S708, the data output function 105 stores the print data generated by the arithmetic processing function 104 in the storage unit 101.

The method for generating print data according to the first, second, and third embodiments of the present invention is executed by the apparatus and software having the configuration shown in FIG. 17, which is executed by a computer and application software. It may be realized.

A specific example of generating print data using conventional automatic typesetting software is shown. For example, the processing time when using Morisawa MVP7 (registered trademark) is 3,076 ms / case, and the processing time when generating print data of the same design using Fujifilm FormMagic4 (registered trademark) is 1,511 ms. / It was a case. On the other hand, when the print data of the same design was generated according to the above embodiment, the processing time was 193 ms / case, and the generation time was significantly shortened.

As described above, according to the above embodiment of the present invention, the PDF format file created by the design software is used as the source data for generating the print data, and is included in the source data in principle. Since the stream information is simply replaced with new stream information while maintaining the property information, print data can be generated at high speed. This improves productivity.

In addition, since ordinary design software on the market has a function of storing a PDF format file or the like in a storage unit, it can be used as source data and is reproducible with conventional automatic typesetting software. It is possible to design without being conscious of the possibility of. This improves workability.

Further, since the property information included in the source data is not modified in principle, the design expression having a high degree of freedom of the source data can be maintained.

More specifically, unlike the search / replace method of searching and replacing a predetermined character from document data, the stream information specified by the setting data is sought and only the stream information is replaced without performing a search. Therefore, the number of determinations in the arithmetic processing of the software can be minimized.

Although embodiments of the present invention have been described, the above embodiments are presented as an example and are not intended to limit the technical scope of the invention.
