On the other hand, when the user selects and operates the OK button icon 703 while the patch to be added has not been moved to the patch row of the custom wedge patch image 701, the control unit 101 adds the patch in the arrangement pattern as described below. The patch to be patch is automatically arranged in the patch sequence of the custom wedge patch image 701, and is controlled to be stored in the RAM 102 and the storage unit 105 as the patch sequence of the changed custom wedge.

<Example of automatic patch addition position selection>
FIG. 8 is a conceptual diagram showing a processing example of automatically selecting the patch addition position when the user does not select the patch addition position selection image 700. FIG. 8A shows an example of automatic position selection of an additional patch when the custom wedge before addition is similar to the standard patch arrangement. FIG. 8B shows an example of automatic patch position selection when the custom wedge before addition is different from the standard patch arrangement. In FIG. 8, as in FIG. 7, in order to make it easy to distinguish the types of patches on the drawings, the patches are designated by the reference numerals “A” to “M” for convenience. There is.

When the user does not select the position of the additional patch in the patch addition position selection image 700, the control unit 101 arranges the patch for the wedge data of various standards stored in the ROM 103 or the storage unit 105. Searches for a standard wedge 801 arranged in the same way as the custom wedge 802 before patch addition.

Then, when the control unit 101 has a wedge 801 of the same standard as the custom wedge 802 before adding the patch, the patch to be added (hereinafter, as shown in FIG. 8A) in the wedge 801 of the standard. (Called an additional patch) Acquires the position information of a patch having the same CMYK value as 803. The control unit 101 acquires the position information for adding the additional patch 803 in the custom wedge 802 before the patch addition based on the position acquired in this way. By adding the additional patch 803 to the position acquired in the custom wedge 802 before the patch addition, the control unit 101 makes the custom wedge 804 after the patch addition similar to the patch arrangement of the standard wedge 801. Then, the modified custom wedge is applied and controlled to be stored in the RAM 102 and the storage unit 105.

On the other hand, when the control unit 101 does not have the wedge 801 of the same standard as the custom wedge 802 before the patch addition, the control unit 101 attaches the patch to be added (hereinafter referred to as an additional patch) 803 as shown in FIG. 8 (b). An additional patch 803 is added at the beginning of the patch row or at the end of the patch row in the custom wedge 802 before the patch is added, and a process of obtaining the custom wedge 805 or 806 after the patch is added is executed.

The custom wedge 805 of FIG. 8 (b-1) is the first example of the custom wedge after the patch addition of the first additional pattern in which the additional patch 803 is added to the head position of the patch row in the custom wedge 802 before the patch is added. The custom wedge 806 of FIG. 8B-2 is the second example of the custom wedge after the patch addition of the second additional pattern in which the additional patch 803 is added to the end position of the patch row in the custom wedge 802 before the patch is added.

When the user does not select the position of the patch to be added in the patch addition position selection image 700, the user decides whether to add the additional patch 803 at the beginning or the end of the patch column in the custom wedge 802 before adding the patch. The control unit 101 stores and sets the position information in the control unit 101 based on the data input from the input unit 107 or the like, and the control unit 101 determines the position information of either the beginning or the end of the patch string in the custom wedge 802 based on the setting. The additional patch 803 is added to the position at the beginning or the end of the patch row in the custom wedge 802 based on the acquired position information. The setting can be changed at the convenience of the user. The control unit 101 determines whether to add the additional patch 803 to the beginning or the end of the patch row in the custom wedge 802 before the patch addition, based on the patch arrangement pattern of the custom wedge 802 before the patch addition. May be decided. Further, regarding whether to add the additional patch 803 to the beginning or the end of the patch column in the custom wedge 802 before the patch addition, the data specifying either the beginning or the end is set as the default data in the control unit 101. The additional position may be determined based on the default data. In that case, the user may be able to change the additional position.

As shown in FIGS. 8A and 8B, even if the user does not select the position of the patch to be added in the patch addition position selection image 700, the control unit 101 automatically transfers the additional patch to the custom wedge. The change of the custom wedge to be added is executed, and the changed custom wedge is stored in the RAM 102 and the storage unit 105.

<Custom wedge color verification process>
Hereinafter, in the printing system shown in FIG. 1, a flowchart of a custom wedge color verification process for executing a color verification method using a custom wedge capable of setting verification items and adding patches as shown in FIGS. 2 to 8. Will be explained by.

<Verification accuracy notification processing>
Hereinafter, in the printing system shown in FIG. 1, the processing of the verification accuracy notification process for notifying the verification accuracy of the verification items as shown in FIGS. 13 and 14 will be described with a flowchart.

FIG. 15 is a flowchart showing the verification accuracy notification process. The verification accuracy notification process is executed by the control unit 101 (CPU 102).

The CPU 102 executes the following processing in the verification accuracy notification processing. According to S31, S31 acquires data on the number of patches required for accuracy calculation of verification items defined by a specific standard when color verification is performed using a custom wedge. Next, according to S32, among the patches included in the custom wedge, the data of the patch corresponding to the patch required for the accuracy calculation of the verification item defined by the specific standard is acquired.

In S33, the accuracy of the verification item is calculated using the accuracy calculation formula described above based on the patch data acquired in S31 and S32. According to S34, the accuracy of the verification item as shown in FIG. 13 is obtained based on the patch data corresponding to the patch required for the calculation of the accuracy of the verification item acquired in S32 and the calculation result of the accuracy in S33. The verification accuracy notification image 920 to be notified is displayed.

Next, S35 determines whether or not there is a selection operation for designating a change in verification accuracy by the user as described with reference to FIG. If it is determined in S35 that there is no selection operation for specifying the change in verification accuracy, the process ends. On the other hand, when it is determined in S35 that there is a selection operation for specifying the change of the verification accuracy, the change desired to be input and set in the verification accuracy display unit 921 in the verification accuracy notification image 920 required for changing the accuracy. The patch (additional patch) that needs to be added to realize the accuracy value is obtained from the patch required for the accuracy calculation of the verification item defined in the standard, and is shown in FIG. 14 by S36. The verification accuracy change notification image 930 including the post-change verification accuracy display unit 931, the pre-change patch image 932, and the post-change patch image 933 is displayed.

[Another example of patch change in color verification]
Next, another example of changing the patch in the case of color verification in the printing system of FIG. 1 will be described. In the custom wedge color verification method in the above-described embodiment, when the allowable value cannot be calculated for the verification item of the custom wedge, the patch change process is executed by adding a patch that enables the calculation of the allowable value. An example was explained. Not limited to this, the patch change process for making the permissible value computable is the process of changing the color of a specific patch in place of the process of adding a patch or in addition to the process of adding a patch. May be executed.

For example, in a custom wedge, the color of a patch that is considered less important for color verification than other types of patches can be calculated for the tolerance of the color validation item for which it is determined that the tolerance cannot be calculated. You may change the patch by changing the color to. In this way, when changing the permissible value of the color verification item for which it is determined that the permissible value cannot be calculated to a color that can be calculated, for example, the information that can identify the patch to be added shown in FIG. 6 is notified. In addition to the process of notifying the information that can identify the patch to be added, or by executing the process of notifying the information that can identify the patch to be changed, the above-mentioned patch is added. The same processing as the processing to be executed corresponding to the execution of control may be executed. As described above, the process of changing the color of the patch may be executed in addition to the process of adding the patch as in the above-described embodiment.

In this way, in the step of changing the patch contained in the custom wedge for which the selected verification item is determined to be unverifiable, changing the patch changes the patch contained in the custom wedge to a different color. May be included.

[Effects obtained by the embodiment]
