DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of an image determination system for printing, an image determination method for printing, and an image determination program for printing according to the present invention will be described below with reference to the drawings. In addition, this invention is not limited by this embodiment. In addition, components in the following embodiments include components that can be easily replaced by those skilled in the art, or components that are substantially the same.

FIG. 1 is a diagram showing an example of a printing image determination system (hereinafter referred to as a determination system) SYS according to this embodiment. As shown in FIG. 1, the determination system SYS includes a control device 10, an input device 20, and a display device 30. FIG. Note that the input device 20 can input information to the control device 10 . In this embodiment, for example, a configuration in which the keyboard 21 and the mouse 22 are provided as the input device 20 is taken as an example, but the present invention is not limited to this, and other input devices such as a touch panel may be provided. As the display device 30, for example, a display device such as a liquid crystal display is used, but other display devices may be used.

The control device 10 is connected to the printing device P and transmits image data including an image for printing to the printing device P. FIG. The image data including the image for printing has been created in advance by the user. FIG. 2 is a block diagram showing a configuration example of the control device 10. As shown in FIG. As shown in FIG. 2 , the control device 10 has a control section 11 and a storage section 12 .

The storage unit 12 has a color system data storage unit 16 and a reference data storage unit 17 . The color system data storage unit 16 stores color data for each color system. Color data for each color system such as the CMYK color system, the RGB color system, the Lab color system, the XYZ color system, and the Munsell color system is stored.

The reference data storage unit 17 stores, as reference data, items related to predetermined standards based on prohibition of use of images for printing. For example, there are cases where colors (hue, brightness, saturation) that are prohibited from being used for images displayed on signboards or the like are stipulated in some areas, such as landscape ordinances. In addition, although such a regulated color may be used if it is equal to or less than a predetermined area ratio with respect to the entire image, it may be prohibited to use it in excess of the predetermined area ratio.

In the program storage unit 18, when image data including an image for printing to be printed by the printing apparatus P is input to the control device 10, the image for printing included in the input image data is stored according to a predetermined usage prohibition regulation. A printing image determination program is stored that causes the control device 10 to perform a process of determining whether or not the criteria are met. The program storage unit 18 may store a display program for displaying on the display device 30 the determination result determined by the print image determination program. Further, the print image determination program may include the display program.

In this embodiment, the storage unit 12 is stored in advance as the reference data based on the predetermined reference based on the prohibition of use as described above. When image data including an image for printing is input to the control device 10, the control unit 11 compares the image data with the reference data so that the image for printing included in the image data satisfies a predetermined reference. Determine whether or not The control unit 11 has a color system adjustment unit 13 , a color determination unit 14 and an area determination unit 15 .

When the color system of the reference data and the color system of the ink in the printing apparatus P are different, the color system adjustment unit 13 converts one color system into the other color system. For example, in the landscape ordinance as described above, colors to be regulated (regulated colors) are set based on the Munsell color system. On the other hand, in the printing apparatus P as in this embodiment, ink colors are set based on, for example, the CMYK color system or the RGB color system. Therefore, in the present embodiment, the color system adjustment unit 13 converts the color system of the printing apparatus P into the Munsell color system.

In this case, the color system adjustment unit 13 first converts ink colors set in the CMYK color system or the RGB color system into colors in the Lab color system. After that, the color converted into the Lab color system is converted into the color of the XYZ color system. Then, the color converted into the XYZ color system is converted into the color of the Munsell color system. The color system adjustment unit 13 uses the color system data stored in the color system data storage unit 16 of the storage unit 12 when converting the color system. In this way, by sequentially converting the colors of the ink set in the CMYK color system or the RGB color system, it is possible to obtain the colors of the Munsell color system corresponding to the ink colors with high accuracy.

The color determination unit 14 determines whether or not the image for printing converted into the Munsell color system includes the regulated color. In this case, regulated colors include colors that are prohibited or regulated by landscape ordinances or the like. Such restricted colors are stored in the reference data storage unit 17 as reference data. The color determination unit 14 compares the color of each pixel of the image for printing converted into the Munsell color system with the regulated color of the reference data, and determines whether or not they are the same color. When determining that both are the same color, the color determination unit 14 determines that the image for printing includes the regulated color. Further, when determining that both are not the same color, the color determining unit 14 determines whether or not the color of each pixel of the image for printing is similar to the regulated color.

When comparing the color of each pixel of the image for printing with the regulated color of the reference data, the color determination unit 14 can perform the comparison based on hue and saturation, for example. For example, depending on landscape ordinances, there are cases where a range is provided for the saturation of the regulated colors, such as regulating colors that have a certain level of saturation or more in a predetermined hue. In such a case, the color determination unit 14 determines that the colors are the same when the hue and saturation of the two to be compared are the same or within a range.

When determining that the print image includes the restricted color, the area determination unit 15 determines whether or not the area ratio of the region to which the restricted color is added to the entire print image satisfies a predetermined area standard. do. In this case, the area determination unit 15 obtains the number of pixels determined to be the regulated color, and calculates the ratio of the print image to all pixels. The area determination unit 15 can determine whether or not the area ratio satisfies a predetermined area reference value by comparing the calculation result with the area reference value of the reference data. For example, if the landscape ordinance prohibits the use of a regulated color that exceeds a predetermined area ratio, the area determination unit 15 determines that the area ratio is equal to or exceeds the predetermined area if the calculation result is equal to or less than the area reference value. Judged as meeting the criteria. On the other hand, when the calculation result exceeds the area reference value, the area determination unit 15 determines that the area ratio does not satisfy the predetermined area reference.

When the area determination unit 15 determines that the area ratio does not satisfy the predetermined area standard, the control unit 11 determines that the image for printing does not satisfy the predetermined standard. The control unit 11 outputs the determination result.

The display device 30 displays the determination results output from the control device 10 . FIG. 3 is a diagram showing an example of a display screen when displaying the determination result by the control unit 11. As shown in FIG. As shown in FIG. 3, the control unit 11 causes the display device 30 to display a determination result window 40 after making the determination. The determination result window 40 has an image display portion 41, a target area display portion 42, an operation button display portion 43, a color information display portion 44, an overall information display portion 45, and a confirmation button display portion 46. there is

The image display unit 41 displays the print image IM. The target area display section 42 displays the name of the determined area where the determination has been made. Landscape ordinances differ from region to region, but in the present embodiment, determination results corresponding to each region are displayed.

The operation button display section 43 is used to add, change, or delete reference data for the area displayed on the target area display section 42 . The operation button display section 43 has an add button 43a for adding the reference data set for the area, a change button 43b for changing the reference data set for the area, and a delete button 43b for deleting the reference data set for the area. A delete button 43c is displayed.

The add button 43a, the change button 43b, and the delete button 43c displayed in the operation button display section 43 are selected by moving the mouse cursor and clicking when the mouse 22 is used as the input device 20, for example. Moreover, when a touch panel is used as the input device 20, it selects by touching a target area|region.

The color information display section 44 displays various types of information about colors that are determined by the color determination section 14 to be regulated colors among the colors included in the image for printing. In the color information display section 44, for example, target color data 44a indicating the color of an area (hereinafter referred to as target area IMa) determined to be the same as or similar to the regulated color in the image for printing IM, Pre-conversion color system data 44b representing the color of the target area IMa in the image for printing input to the control unit 11 by numerical values of the color system (CMYK color system or RGB color system) before conversion, and the Munsell table Post-conversion color system data 44c indicating numerically the color of the target area IMa after conversion into the color system, area ratio data 44d indicating the area ratio of the target area IMa to the entire printing image IM, and the target area IMa is displayed.

In the example shown in FIG. 3, the target area IMa has an area ratio of 50% of the entire print image IM, the color of the target area IMa is red, the color subject to restriction in the use prohibition regulation is red, and the area A case where the reference is 50% or more is taken as an example. In this case, in area A, when a printing image having an area ratio of 50% or more of the entire red area is printed on a signboard or the like and put up, the signboard is subject to regulation.

In such an example, the determination result window 40 displays numerical values indicating red ("C0, M100, Y100, K0", "4 R4/14") as the pre-conversion color system data 44b and the post-conversion color system data 44c. ) is displayed. Further, the area ratio data 44d indicates that the area ratio of the target region IMa is 50%. In addition, the restriction content data 44e indicates that the color is prohibited.

When the control unit 11 determines that the image for printing does not meet the predetermined criteria, the color information display unit 44 may display candidates for colors different from the regulated colors. In this case, the control unit 11 extracts and displays a color different from the regulated color among the colors stored in the reference data storage unit 17 . Colors to be extracted include, for example, colors that have the same hue and whose saturation is not subject to regulation, but are not limited to these.

Further, in the determination result window 40, a highlighted display selection section 44f is provided below the color information display section 44. FIG. The highlighting selection unit 44f selects whether or not to highlight the target area IMa including the color displayed in the color information display unit 44 with respect to other areas. For example, by checking the highlight selection section 44f, the target area IMa is highlighted with respect to other areas. In this case, the highlighting of other areas includes displaying in a manner different from that of other areas. For example, display forms such as blinking the target area IMa, displaying the outline of the target area IMa thick or dark, and displaying the color of the target area IMa so as to be different from other areas are included.

The overall information display portion 45 displays information other than the color information, such as the area ratio of the target area IMa. Information other than the color and the area ratio may be displayed on the overall information display section 45 . The confirmation button display portion 46 displays a confirmation button. By selecting the confirmation button, the determination result window 40 can be closed.

FIG. 4 is a diagram showing an example of a screen displayed when the add button 43a of the operation button display section 43 is selected in the determination result window 40 shown in FIG. As shown in FIG. 4, when the add button 43a is selected, the control unit 11 causes the display device 30 to display a reference data setting window 50 for setting reference data for each region.

The reference data setting window 50 has restriction type selection sections 51 , 52 and 53 . The restriction type selection unit 51 selects whether or not to set a color to be restricted. By checking the restriction type selection section 51, it becomes possible to set the color to be restricted and the area ratio. In the restriction type selection unit 51, the restriction target color setting unit 54 can set the saturation and hue of the restriction target color. The saturation of the regulated color can be set, for example, by inputting a numerical value to the saturation setting section 54a. The hue of the regulated color can be set by adding, changing, or deleting the hue using the hue setting section 54b.

In addition, saturation can be set individually for each hue by the individual setting selection section 54c. FIG. 5 is a diagram showing an example of a screen displayed when saturation is individually set for each hue by the individual setting selection section 54c in the reference data setting window 50 shown in FIG. As shown in FIG. 5, when the add button of the individual setting selection section 54c is selected, an individual setting window 60 is displayed. The individual setting window 60 has a hue selection section 61 , a saturation input section 62 and an operation button 63 . The hue selection section 61 can select a hue to be set from a plurality of candidates. The saturation input section 62 inputs the saturation to be set. The operation button 63 has an add button 63a and a cancel button 63b. When the add button 63a is selected with the hue selected in the hue selection section 61 and the saturation input in the saturation input section 62, the selected hue and the input saturation are added as the reference data of the regulated color. . The cancel button 63b cancels the content selected in the hue selection section 61 and the content entered in the saturation input section 62. FIG. The result of setting the saturation and hue thus set is displayed, for example, in the setting result display section 54d shown in FIG. Also, the area ratio can be set by the area ratio setting unit 55 . The area ratio setting portion 55 can be set by checking the setting selection portion 55a and inputting a numerical value in the area ratio input portion 55b.

Further, as shown in FIG. 4, the restriction type selection unit 52 selects whether to set prohibited colors. A prohibited color is a regulated color that is subject to regulation regardless of the area ratio when included in the image for printing IM. Prohibited colors can be set by checking the restriction type selection section 52 . In the restriction type selection section 52, the prohibited color setting section 56 can set the saturation and hue of the prohibited color. The saturation of the prohibited color can be set, for example, by inputting a numerical value to the saturation setting section 56a. The hue of the prohibited color can be set by adding, changing, or deleting the hue using the hue setting section 56b. Also, as with the regulated colors, the individual setting selector 56c can individually set the saturation for each hue. The saturation and hue setting results are displayed, for example, in the setting result display section 56d.

The regulation type selection unit 53 sets whether to include raster data such as photographs and paintings as objects to be regulated. Raster data may be subject to regulations in some regions. Raster data can be subject to regulation by checking the regulation type selection section 53 . In this case, the control unit 11 may determine whether the image for printing IM is raster data by determining whether the image for printing IM has a data format specific to raster data. Image data of raster data is stored in the storage unit 12, and the control unit 11 compares the image data for printing IM with the image data in the storage unit 12 to determine whether the image for printing IM is raster data. It may be determined whether

As shown in FIG. 6, the user creates image data including the image for printing IM and inputs the image data to the control device 10 (step S10). When the image data is input, the control unit 11 determines whether or not the print image IM included in the input image data satisfies a predetermined standard based on the prohibition of use (step S20). In step S20, the control unit 11 compares the image for printing IM with the reference data to determine whether the image for printing IM satisfies a predetermined standard.

FIG. 7 is a flow chart showing an example of determination step S20. As shown in FIG. 7, the color system adjustment unit 13 determines whether the color system of the image for printing IM included in the input image data matches the color system of the regulated color set as the reference data. If different, the color system of the image for printing IM is converted into the color system of the regulated color (step S21). In step S21, the color system adjustment unit 13 converts the CMYK color system or the RGB color system of the image for printing IM into the Munsell color system of the regulated colors.

After the color system is converted, the color determination unit 14 determines whether or not the colors of the image for printing IM after color system conversion satisfy a predetermined standard (step S22). In step S22, the color determination unit 14 compares the color of each pixel of the image for printing after converting the color system with the regulated color of the reference data, and determines that both are the same color (or similar color). Determine whether or not When the two are not the same color (or similar color), the color determination unit 14 determines that the color of the image for printing IM after converting the color system satisfies a predetermined standard. When both are the same color (or similar color), the color determination unit 14 determines that the color of the image for printing IM after converting the color system does not satisfy a predetermined standard.

In step S23, the area determination unit 15 obtains the number of pixels determined to be the regulated color, and calculates the ratio to all pixels of the image for printing IM. The area determination unit 15 determines whether or not the area ratio satisfies a predetermined area reference value by comparing the calculation result with the area reference value of the reference data.

If it is determined in step S22 that the color of the image for printing IM after color system conversion satisfies a predetermined standard (Yes in step S22), or if the target area IMa to which the regulated color is added in step S23 to the entire print image IM satisfies the predetermined area standard (Yes in step S23), the control unit 11 controls the print image IM included in the input image data to be prohibited from use. (Yes in step S24 and step S20).

On the other hand, if it is determined in step S23 that the area ratio of the target area IMa to which the regulated color is applied to the entire print image IM does not satisfy the predetermined area standard (No in step S23), the control unit 11 , it is determined that the print image IM included in the input image data does not satisfy a predetermined standard based on the prohibition of use (step S25, No in step S20).

If it is determined in step S20 that the predetermined criteria are satisfied (Yes in step S24 and step S20), the control unit 11 causes the display device 30 to display that the criteria are satisfied ( step S30). In step S30, the control unit 11 causes the general information display unit 45 of the determination result window 40 shown in FIG. 3, for example, to display that the image for printing IM satisfies the criteria.

If it is determined in step S20 that the predetermined criteria are not met (step S25, No in step S20), the control unit 11 causes the display device 30 to display that the criteria are not met (step S40). In step S40, the control section 11 causes the color information display section 44 of the determination result window 40 shown in FIG. 3, for example, to display information about the color of the target area IMa.
