Description

  The present invention relates to a printed pattern raising system and program for raising a printed pattern such as a building board, and more particularly to a printed pattern raising system and program that can handle a small amount of data efficiently.

  In general printing processing, an original image such as a photograph is enlarged and developed on a surface to be printed, converted into CMYK (Cyan Magenta Yellow BlacK) print control data, and ink jet nozzle opening / closing control is performed. That is, one print control data is created for an image developed on one print surface.

  However, in the printing of a long rectangular-shaped printing surface such as a building board, the amount of printing control data stored on the entire printing surface is enormous. Even when trying to expand and develop variations of an image in which the original image is partially changed little by little, it is the same that one print control data is created for one printing surface, If the number of patterns increases, the amount of print control data to be stored becomes extremely large (the problem of a large amount of data).

In addition, since the image to be printed (print pattern raising) has a large area to be printed, it takes a considerable amount of time to create a uniform pattern for each part (operation efficiency problem). For this reason, it has been attempted to increase the efficiency of pattern raising work by a method of creating a pattern having a scale angle (about 30 cm square) and joining it to create a pattern with a large area (for example, patents). Reference 1).

  However, in the case of the pattern joining method, the monotonous feeling that the same pattern is repeated cannot be avoided.

  SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a print pattern raising system and a program that can efficiently handle a natural texture by reducing the amount of data to be handled.

  The printed pattern raising system according to the present invention includes a pattern shape display unit that displays a plurality of pattern shapes, and a pattern shape distribution unit that disperses the pattern shape displayed by the pattern shape display unit and selected by an operator's instruction on the printing surface. A texture distribution display means for displaying the distribution of the texture assigned to each of the pattern areas of the printed surface determined by the pattern shape distributed by the pattern shape distribution means, and the distribution by the pattern texture distribution display means The pattern texture distribution means for allocating each texture to each pattern area, and the pattern texture extraction means for cutting out the partial texture data in the shape of the corresponding pattern area from the texture pattern of the texture allocated by the pattern texture distribution means.

  Further, by further providing a background texture display means for displaying a candidate for a print background texture to be allocated to the print background area, an arbitrary background texture can be easily allocated.

  The pattern shape dispersal means randomly disperses the pattern shape, the pattern texture dispersal means randomly assigns the pattern texture, and the pattern texture cutout means randomly cuts out the partial texture data. You can produce a pattern with a nice texture.

  Further, the present invention provides a computer with a pattern shape display means for displaying a plurality of pattern shapes, and a pattern shape distribution means for distributing the pattern shape displayed by the pattern shape display means and selected by an operator's instruction on the printing surface. The pattern texture distribution display means for displaying the distribution of the texture to be assigned to each of the pattern areas on the printed surface determined by the pattern shape distributed by the pattern shape distribution means, and the distribution by the pattern texture distribution display means Pattern texture distribution means for allocating each texture to each pattern area, and pattern texture extraction means for extracting partial texture data in the shape of the corresponding pattern area from the texture pattern of the texture allocated by the pattern texture distribution means This is a program for functioning as a system.

  According to the present invention, it is possible to reduce the amount of data to be handled by raising the print pattern with a natural texture efficiently.

  Specifically, the operator can realize the pattern raising with a natural texture by repeating the pattern raising several times with the support of the system.

  In addition, regarding the data amount, the data amount handled as a whole is reduced by having the data divided into a monotonous background region with a small amount of data and a complicated region with a large amount of data.

  In addition, it has a separate texture pattern, and the data for each substrate such as a building board need only have the texture type and the cut-out position data (related to the pattern area), so the total amount of data handled is small. Become.

  The best mode for carrying out the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a diagram for explaining plate shape display in a printed pattern raising system according to an embodiment of the present invention. First, the contour shape is determined and patterned for all types of printing surfaces. In the case of a building board, the surface to be printed has a rectangular shape, and therefore the board shape pattern is determined by the vertical and horizontal dimensions {l, m} of all boards used for printing. Specifically, as shown in FIG. 1, all building boards to be used for printing can be patterned by coordinates {xi, yi}. Therefore, here, each is databased as BP1 (= {x1, y1}), BP2 (= {x2, y2}),.

  FIG. 2 is a diagram for explaining the layer structure of the print pattern data in the print pattern raising system according to the embodiment of the present invention. In the present embodiment, it is considered that the printing surface is composed of one printing ground area and a plurality of pattern areas distributed on the printing ground area. The former is a continuous image area, and the latter is an independent image area. From the image composition surface, the print ground area is handled as layer 1 and the pattern area is handled as layer 2.

  FIG. 3 is a diagram for explaining a pattern area pattern in a printed pattern raising system according to an embodiment of the present invention. The pattern area is databased as follows. Black and white information is acquired by scanning an original image such as a photograph (a predetermined threshold value is determined to obtain binarized information), and lines formed in the main scanning direction (direction perpendicular to the building board conveyance direction) Detects all area images formed by dividing images in the sub-scanning direction (direction orthogonal to the main scanning direction), and determines multiple individual contour shapes for all pattern regions from the end position coordinates. Is determined as the contour coordinates. Each pattern region whose shape is specified by the contour coordinates is stored in a database as a pattern region pattern DP1 (= {contour coordinate 1}), DP2 (= {contour coordinate 2}),.

  FIG. 4 is a diagram for explaining a divided print pattern in the print pattern raising system according to the embodiment of the present invention. Next, each pattern region is expanded and developed so as to be randomly distributed and arranged on the printing surface of the selected plate-shaped pattern (by the input operation of the operator).

  Each pattern area is dispersed so as not to overlap each time the pattern is raised. As shown in FIG. 4, the distance from the “print start edge of the printing surface” to the “print start edge of each pattern region” (here, the x coordinate of the “print start edge of the print surface” is Since it is set to 0, it is numbered as A1 to A10 according to “the x coordinate of“ print start side end of each pattern area ”). Each pattern area in which the positions of A1 to A10 are fixed is one pattern area distribution pattern of the pattern area pattern set {DP1 to DP10}.

  Then, the printing base pattern A0 is determined from the selected plate shape pattern and the determined pattern region dispersion pattern. That is, the printed ground pattern A0 is a white plate image in layer 1 that is the remaining plate image obtained by subtracting the dispersed images of the pattern areas A1 to A10 in layer 2 from the entire plate image of layer 1.

  Here, according to the board shape pattern selected by the operator's input operation, the distribution pattern of the determined pattern area, and the obtained printing ground pattern, the divided printing pattern DIV (= {Plate shape pattern, pattern region dispersion pattern, print ground pattern} = {BP1, A1 to A10, A0}) is determined.

  FIG. 5 is a diagram for explaining a texture pattern in a printed pattern raising system according to an embodiment of the present invention. The texture data to be pasted is made into a database as texture patterns TP1, TP2,... For each of the pattern areas and the print base areas, each of which is determined by the divided print pattern DIV. This texture pattern may be color data unlike the segmented print pattern DIV.

  The texture pattern (including the plain texture pattern) for each pattern area is data that occupies a larger area than each pattern area.

  In addition, the texture pattern (including the plain texture pattern) for the printing ground region is a database of basic texture data having a basic area (the maximum possible printed area, that is, the maximum area of the building board to be handled). Yes.

  FIG. 6 is a diagram for explaining texture pattern assignment in the printed pattern raising system according to the embodiment of the present invention. Each of the selected texture patterns (by the operator's input operation) is randomly assigned to each pattern area according to the designated application frequency (by the operator's input operation). This determines which texture is to be applied to each pattern area. For example, when TP1: 50% and TP2: 50%, TP1: TP2 = 5: 5 is allocated to each pattern area, and TP1: 40%, TP2: 20%, TP3: 40% , TP1: TP2: TP3 = 4: 2: 4 is assigned to each pattern area, and when TP1: 40%, TP2: 50%, TP3: 10%, TP1: TP2: TP3 = 4 : Randomly assign to each pattern area at a ratio of 5: 1. Thereby, each pattern texture pattern is distributed and allocated to each pattern area.

  FIG. 7 is a diagram for explaining the extraction of the texture pattern in the printed pattern raising system according to the embodiment of the present invention. Currently, the texture pattern TP is assigned to each pattern shape pattern. Therefore, this time, it is determined which part of the texture pattern TP is to be pasted, that is, which part is cut out from the texture pattern TP. In this embodiment, for each pattern area to which the texture pattern TP is assigned, a partial texture pattern TP is randomly cut out from the corresponding texture pattern TP according to the contour shape of each pattern area. Here, the partial texture data may overlap. FIG. 7 shows an example of three cutouts.

  FIG. 8 is a diagram for explaining the texture pattern allocation of the printing ground area in the printed pattern raising system according to the embodiment of the present invention. The selected texture pattern (by the operator's input operation) is assigned to the print ground area, and the basic texture data (see FIG. 5) is applied to the entire area for the white board image in which the pattern area is white. It is pasted.

  FIG. 9 is a diagram for explaining a pattern confirmation screen in the printed pattern raising system according to the embodiment of the present invention. The obtained board pattern image is set as a candidate 1, and the four pieces (of the same pattern) are arranged adjacent to each other (in order to confirm whether or not the pattern of the joint portion is uncomfortable assuming the construction state). If the user is not satisfied, the “return to operation screen” button 13 is pressed to obtain a pattern image again, and as a candidate 2, the four images are similarly arranged adjacently and displayed together. Here, a comparison with the previously obtained pattern image can also be performed. If any of the candidates is satisfactory, the candidate is identified by pressing the “candidate 1” button 11 or the “candidate 2” button 12 and the “design determination” button 14 is pressed, and the printed pattern is stored.

  In printing, when a divided print pattern is called, it is converted into CMYK data as it is, and further converted into print control data and output.

  FIG. 10 is a flowchart for explaining the operation of the printed pattern raising system according to the embodiment of the present invention. FIG. 11 is a diagram for explaining an operation screen in the printed pattern raising system according to the embodiment of the present invention. First, when the operator presses a “plate shape selection” button 21, the system is linked to the plate shape pattern database, and as shown in FIG. 1, plate shape candidates are displayed on a plurality of sub-screens in terms of vertical and horizontal dimensions (step S 1). The operator selects a plate shape pattern to be used for printing from among them, and presses the “OK” button 22. Next, when the operator presses the “pattern shape selection” button 23, the system is linked to the pattern region pattern database and displays the pattern region pattern illustrated in FIG. 3 as a pattern shape candidate on a plurality of sub-screens (step S2). ), The operator selects a pattern shape to be printed from among them, and presses the “OK” button 24. When the operator presses the “pattern shape distribution” button 25, the selected pattern shape (two-dimensional position and orientation) is randomly distributed in the plate shape (step S3). By repeatedly pressing the “pattern shape dispersion” button 25, the pattern shape can be randomly dispersed each time. When the arrangement of the pattern distribution is decided, when the operator presses the “display 1” button 26, the system is linked with the print base texture database and displays the print base texture candidates 27 (step S4). The texture to be printed is selected from the inside, and the “OK” button 28 is pressed.

  Next, the pattern texture is determined. When the operator presses the “Display 2” button 31, the system is linked with the print texture database and displays three print texture candidates 32 simultaneously, so the operator inputs the application frequency (%) 33 for each. (Step S5), the “OK” button 34 is pressed. When the operator presses the “texture distribution” button 35, as shown in FIG. 6, the system randomly assigns each texture to be distributed to each pattern shape pattern with the determined appearance frequency (step S6). ). By repeatedly pressing the “texture distribution” button 35, each texture can be randomly assigned to each pattern shape pattern each time. Then, when the operator presses the “cut” button 36, the system randomly cuts the partial texture data from the texture pattern assigned to each pattern shape pattern as shown in FIG. 7 (step S7). By repeatedly pressing the “Cut” button 36, each texture pattern can be cut out at random each time. The pattern image candidates can be created by the above operation, and when the operator presses the “next screen” button 37, the system displays a board confirmation screen shown in FIG.

  In addition, this invention is not limited to the said Example.

  The pattern shape dispersion (step S3) may not be performed at random, but a plurality of dispersion states may be determined in advance and selected from them.

  The combination of the printed pattern texture patterns to be pasted on the pattern area (step S6) may be determined in advance, and a plurality of combinations may be selected and selected from them.

  The method of extracting partial texture data from the texture pattern (step S7) is not performed randomly, but a plurality of predetermined texture data may be determined in advance and selected from them, or the extraction method may be designated by a program. May be.

  The application of the present invention is not limited to the printing pattern raising of a building board, but can be used for the printing pattern raising of other general products.

  The printed pattern raising system of the present invention is also realized by a program for causing a computer to function as the printed pattern raising system. This program may be stored in a computer-readable recording medium.

  The recording medium on which the program is recorded may be the ROM itself in the system, or a program reading device such as a CD-ROM drive is provided as an external storage device, and the program is read by inserting the recording medium therein. A possible CD-ROM or the like may be used.

  The recording medium may be a magnetic tape, a cassette tape, a flexible disk, a hard disk, an MO / MD / DVD, or a semiconductor memory.
