In the example of FIG. 5 , these are shown in the print result 411 , but they correspond to the colorimetry locations where colorimetry is performed by the first colorimeter 13 rather than the print result of the print image.
Blue location area 471, ocher location area 472, yellow location area 473, and green location area 474 are also referred to as color location areas.

Here, the radius of each circle of the blue location area 471, the ocher location area 472, the yellow location area 473, and the green location area 474 may be the same or different.
Further, the shape and size of each of the blue position region 471, the ocher position region 472, the yellow position region 473, and the green position region 474 can be arbitrarily determined as the regions to be colorimetric, taking into account errors. You can decide to

The first colorimeter 13 is operated by the first user 14 to perform colorimetry for each of the blue color region 471 , the ocher color region 472 , the yellow color region 473 , and the green color region 474 .

In the example of FIG. 6, the colorimetric numbers of blue location area 471, ocher location area 472, yellow location area 473, and green location area 474 are 1, 2, 3, and 4, respectively.

The first colorimeter 13 transmits the colorimetry position list 2011 to the first printing device 11 when printing fails at one or more colorimetry locations. Then, in the first printing apparatus 11 , the first print processing unit 215 determines the reprint range based on the colorimetry position list 2011 .

Here, in this embodiment, the first colorimeter 13 generates the colorimetry position list 2011 and transmits it to the first printing apparatus 11, and the first print processing unit 215 of the first printing apparatus 11 generates the colorimetry position list 2011. Based on the list 2011, the reprint range is generated by judging whether printing is acceptable based on the content of the colorimetric position list 2011. FIG.

FIG. 7 is a diagram showing an example of the reprint range 2111 according to the embodiment.
The second print processing unit 1017 determines a reprint range 2111 based on the colorimetry position list 2011 .
The reprint range 2111 sets the maximum and minimum values in the X-axis direction and the maximum and minimum values in the Y-axis direction based on the X and Y coordinates included in the colorimetry position list 2011 .

The maximum value in the X-axis direction is a value corresponding to the result of adding a predetermined colorimetry radius to the maximum value of the X coordinate in the colorimetry position list 2011 .
The minimum value in the X-axis direction is a value corresponding to the result of subtracting a predetermined colorimetry radius from the minimum value of the X coordinate in the colorimetry position list 2011 .
The maximum value in the Y-axis direction is a value corresponding to the result of adding a predetermined colorimetry radius to the maximum value of the Y coordinate in the colorimetry position list 2011 .
The minimum value in the Y-axis direction is a value corresponding to the result of subtracting a predetermined colorimetry radius from the minimum Y-coordinate value in the colorimetry position list 2011 .

Here, the colorimetric radius of each color position area may be the same or different.
The example of FIG. 7 shows a case where the colorimetric radius of all color position areas is 1.5.
The first print processing unit 215 sets the inside of the rectangle surrounded by the four points set in the reprint range 2111 as the reprint target area. Also, the first print processing unit 215 changes the printing conditions for reprinting from the printing conditions for the previous printing.
Note that in this example, this reprinting corresponds to the second trial printing.

FIG. 8 is a diagram illustrating an example of a print result of reprinting according to the embodiment.
FIG. 8 shows a first reprint result 511 corresponding to the print result of reprinting.
FIG. 8 shows the XY orthogonal coordinate system shown in FIG.

The first reprint result 511 corresponds to the print medium on which the reprint image is printed.
The first reprint result 511 includes a first blue reprint area 531 that is a blue reprinted area, a first ocher reprint area 532 that is an ocher reprinted area, and a yellow reprinted area. a first yellow reprint area 533 , a third mark 551 and a fourth mark 552 .
Here, the third mark 551 and the fourth mark 552 are printed outside the area where the reprinted image is printed, for example.
The third mark 551 and the fourth mark 552 may be printed simultaneously with the reprinted image, or may be printed before or after the reprinted image is printed.

Here, in the example of FIG. 8, printing is performed for an image portion of a partial area of the print result 411 shown in FIG. In the example of FIG. 5 and the example of FIG. 8, the image to be printed is arranged at the same reference position on the printing medium and printing is performed. and the position of the image portion of the partial area on the print medium according to the example of FIG. 8 is shifted.
Also, in the example of FIG. 8, the length in the Y direction is shorter than in the example of FIG. This is because printing media can be saved because only a portion is printed.
The third mark 551 and the fourth mark 552 are similar to the first mark 451 and the second mark 452 shown in FIG. 5 in that they are used as two origins.

FIG. 8 shows a reprint blue position area 571, which is a circular area centered on a reprint blue center position 571a, which is a stop position, and a circular area centered on a reprint ocher color center position 572a, which is a stop position. and a reprint yellow location area 573, which is a circular area centered at a reprint yellow center location 573a, which is a stop location. These are a blue position region 471, which is a circular region centered on the blue center position 471a shown in FIG. Similar to the yellow location area 473, which is a circular area centered at location 473a, shown in the first reprint result 511, but not the printed result of the reprinted image, but the color measured by the first colorimeter 13. corresponds to the colorimetry point where
Reprint blue location area 571, reprint ocher location area 572, reprint yellow location area 573, and reprint green location area 574 are also referred to as reprint color location areas.

In the example of FIG. 5, the blue print area 431, the ocher print area 432, and the yellow print area 433 where printing fails are close to each other, so that in the example of FIG. , a first blue reprint area 531, a first ocher reprint area 532, and a first yellow reprint area 533 are contained in nearby areas. As another example, the location where colorimetry is performed for the green printing region 434 is far from the location where colorimetry is performed for the other colors, so the printing of the green printing region 434 fails and the printing of the other colors fails, a wider range of print media is reprinted than in the example of FIG.

The first colorimeter 13 is operated by the first user 14 to measure the color of each of the reprint blue location area 571 , the reprint ocher location area 572 , and the reprint yellow location area 573 .
Then, the first colorimeter 13 determines whether the result of colorimetry is acceptable based on the acceptance/rejection conditions for printing, and stores the result of the acceptance/rejection determination as a colorimetry position list.

In the first reprint result 511, when the first colorimeter 13 determines that printing has succeeded based on the colorimetry results for all of the reprint color position areas, the first printer outputs information to that effect. 11 may be sent. When receiving the information from the first colorimeter 13, the first printing device 11 performs actual printing of the entire print image under the current printing conditions.
Here, in the first reprint result 511, the first colorimeter 13 does not notify the first printing apparatus 11 that printing has been successful based on the colorimetry results for all the reprint color position areas. , the first user 14 may operate the first printing device 11 to notify the first printing device 11 .

On the other hand, in the first reprint result 511, if it is determined that printing has failed based on the colorimetric results for any one or more reprint color position areas, reprint processing and colorimetric processing are performed again. .

Here, in the examples of FIGS. 4 to 8, the blue center position 471a, the ocher center position 472a, and the yellow center position 473a, which are judged to have failed printing based on the colorimetric results, are examples of the first positions. The location area 471, the ocher location area 472, and the yellow location area 473 are each examples of the first area.
In addition, in the examples of FIGS. 4 to 8, the green center position 474a, which is judged to have been successfully printed based on the colorimetric results, is an example of the second position, and the green position area 474 is an example of the second area.

FIG. 9 is a diagram showing an example of the procedure of processing performed in the first printing system 1 according to the embodiment.
The processing of steps S1 to S10 performed in the first printing system 1 will be described.

In the process of step S1, the first printing device 11 performs trial printing of a print image.
Here, the first printing apparatus 11 may perform test printing under the control of the first information processing apparatus 12 or may perform test printing under the control of the first user 14 .
In the first printing system 1, after the process of step S1, the process proceeds to step S2.

In the process of step S2, the first user 14 holds the first colorimeter 13 and moves it between marks on the medium on which colorimetry is to be performed, thereby setting the origin of the colorimetry position for the print result of the test print. . Specifically, when performing the colorimetry of FIG. 5, the first user 14 moves the first colorimeter 13 from the first mark 451 to the second mark 452 . When performing the colorimetry of FIG. 8, the first user 14 moves the first colorimeter 13 from the third mark 551 to the fourth mark 552 . The first printing system 1 calculates to which coordinates the first colorimeter 13 has been moved by the movement vector of the movement of the first colorimeter 13 after that, based on the movement vector in this movement and the position information of the mark.
In the first printing system 1, after the process of step S2, the process proceeds to step S3.

In the process of step S3, the first user 14 holds and operates the first colorimeter 13 to perform colorimetry for one color of the print result of the test print. At this time, the first user 14 moves the part where the colorimetry of the first colorimeter 13 is performed to the part where the colorimetry is performed in the print result, and the colorimetry of the part is performed by the first colorimeter 13. let it happen Thereby, the first colorimeter 13 acquires the coordinates of the location calculated based on the colorimetry result of the location and the movement vector up to the location.
In the first printing system 1, after the process of step S3, the process proceeds to step S4.

When the first colorimeter 13 determines that the printing has succeeded, it becomes OK in step S4, and the first printing system 1 proceeds to the process of step S6.
On the other hand, if the first colorimeter 13 determines that printing has failed, the result is NG in step S4, and the first printing system 1 proceeds to the process of step S5.
