- coordinate position data Dc (i, j), Dm (i, j), for determining the position and shape of the object character Tl, figure # 2 and image # 3
- Dy (i, j) and Dk (i, j) are transformed into He (i, j), Hm (i, j), Hy (i, j), Hk (i, j) (Fig. 4)
- the coordinates are converted to correspond to the shape of paper Q (see Fig. 8).
- each coordinate position data Dc (i, j), Dm (i, j), D y (i, j) and Dk (i, j) are coordinate-transformed so as to be the object position corresponding to the shape of the deformed sheet Q and the shape of the object itself.
- the coordinate positions of the objects (characters Tl, graphics # 2, and images # 3) included in the PDF data PDFc, PDFm, PDFy, and PDFk can be changed to the coordinate positions corrected for expansion and contraction.
- the object (character Tl) is similarly applied to the first 'direction X' corresponding to the first direction X, which shows the correction example in the second 'direction Y' corresponding to the second direction ⁇ of the paper Q. , Figure ⁇ 2 and image ⁇ 3) can be changed. Note that either one of the first 'direction X' and the second 'direction Y' may be fixed, and the other side may be subjected to extension correction only.
- the data of the character T1 is data of outline characters, it is treated as graphic data (vector data) that can be represented by a plurality of coordinate information or the like by using a mathematical expression or the like. be able to.
- the types of object data are substantially two types of data: image # 3 and figure # 2.
- the coordinates may be transformed by scaling in the directions along the first 'direction X' and ⁇ or the second 'direction Y'. This makes it possible to correct the coordinate position data of the scaled character Tl and the circumscribed rectangles ⁇ 'and T3' of the image ⁇ 3 (see Fig. 5).
- FIG. 6 is a flowchart showing the flow of the print data creation process.
- PS data or PDF data is created by the layout editing device 11 (step S1), and the created PS data or PDF data is imposed by the imposition device 12 as necessary (step S2).
- the deformation information in the deformation information table of the file device 3 is automatically set from the printing conditions in the deformation information input means P1 (step S3).
- step S4—S10 the printing data for each printing plate from the layout editing device 11 and Z or the imposition device 12 is corrected for expansion and contraction by the correction means P2 as shown in FIG. 1 (steps S4—S10). .
- the data created by the layout editing device 11 and Z or the imposition device 12 is the separated data corresponding to each of the four types of print images (step S4). )
- the process directly proceeds to step S10, where the four types of print images are output.
- the corresponding separated data step S4 and the PS data (step S5), respectively, the corresponding separated PDF data is converted by the PDF conversion means P21. It is converted to PDFc, PDFm, PDFy, PDFk (Step S6), and then goes to Step S10.
- step S4 when the data created by the layout editing device 11 and Z or the imposition device 12 is separated !, na! /, Data (step S4), and is a single PDF data.
- Step S7 the data is separated into separated PDF data PDFc, PDFm, PDFy, and PDFk corresponding to the four types of print images by the PDF separation means P22 (Step S9).
- the data is not separated (Step S4) and is a single PS data (Step S7)
- the data is separated by the PDF conversion means P21.
- the PDF data is converted into a single PDF data (Step S8), and the converted separated data is converted into a single PDF data.
- Separated PDF data corresponding to the print image is separated into PDFc, PDFm, PDFy, and PDFk (step S9), and step S10 Row.
- step S10 all the objects (characters Tl, figure # 2 and image # 3) in the separated PDF data P DFc, PDFm, PDFy, PDFk corresponding to the respective print images are processed.
- the position and shape of the object are changed based on the corresponding coordinate position data (see FIG. 3) and the deformation information (see FIG. 4) set by the deformation information input means P1.
- Expansion / contraction correction is performed in a direction (for example, the first 'direction X' and ⁇ or the second 'direction Y') corresponding to the direction to be expanded / contracted (see FIG. 5).
- the printing data creation device 10 and the printing data creation program ⁇ use the printing plate creation device in CTP printing and the printing plate creation device provided in the DI printing machine prior to creation of a printing plate. Therefore, since the expansion / contraction correction of the print data PDFc, PDFm, PDFy and PDFk is performed, it is not necessary to control the position correction of the imaging device in the printing plate making device. Therefore, it is not necessary to provide a correction device for each imaging device, and the cost of the device can be reduced accordingly, and the printing plate preparation device can be operated stably. Also, prior to the binarization processing of the printing plate creation data, the printing data PDFc, PDFm, PDFy, and PDFk are corrected for expansion and contraction, and the binarization processing is performed. For creating a digitized printing plate It is not necessary to correct the image position when creating a printing plate of binarized data. Therefore, it is possible to prevent a decrease in print quality due to an image position correction at the time of creating a printing plate.
- the correction means P2 for all the object (character, graphic and image) data constituting each print image, the corresponding coordinate position data and the deformation information input means P1 are set. Based on the deformation information, expansion / contraction correction in a direction (for example, the first 'direction X' and Z or the second 'direction ⁇ ') corresponding to the direction in which the paper is to be expanded / contracted is performed.
- a direction for example, the first 'direction X' and Z or the second 'direction ⁇ '
- the expansion / contraction correction is performed on each of the printing data PDFc— ⁇ DFk for cyan, magenta, yellow, and black. However, at least one of the data may be subjected to the expansion / contraction correction. If the body Q is not initially formed with an image, or if it is initially formed but does not need to be aligned with the position of the image on which the image is printed The expansion / contraction correction may be omitted for the corresponding print data.
