It is also conceivable that the image data processing device 54 is realized by a circuit such as an ASIC (Application Specific Integrated Circuit).

The CPU 51 operates as a job control unit 5a and a parameter setting unit 5b by executing the various programs.

The job control unit 5a controls the image reading device 1, the printing processing device 2, the image data processing device 54, and the communication device 4.

For example, the job control unit 5a causes the image reading device 1 to execute the reading process, causes the image data processing device 54 to execute a process of converting the read image data Di0 into transfer data in a predetermined format, and causes the transfer.

Further, for the user, it is possible to set a plurality of printing conditions in which some or all of the values of the plurality of printing parameters are different, and to confirm the printed matter obtained by the printing process under the plurality of printing conditions. It takes a lot of time and effort.

In the image forming apparatus 10, the CPU 51 and the image data processing apparatus 54 execute the image quality confirmation print control described later. This makes it possible to provide an image forming apparatus 10 that makes it easy to set the values of the plurality of print parameters while checking the output image.

As will be described later, the job control unit 5a causes the print processing apparatus 2 to execute the test print process and the main print process in the image quality confirmation print control.

The test printing process is a process of forming a plurality of test images P1 and a plurality of identification information D0 on the sheet 92 as shown in FIGS. 5 to 7, for example. The plurality of test images P1 are images formed on the sheet 92 under a plurality of printing conditions.

The plurality of identification information D0 is information for identifying the plurality of printing conditions. Therefore, it can be said that the plurality of identification information D0 is the information for identifying the plurality of test images P1. In the example shown in FIGS. 5 to 7, the identification information D0 is a number for identifying the plurality of printing conditions. It is also conceivable that the identification information D0 is a number, a character, a symbol, or a combination thereof.

On the other hand, the present printing process is a process of forming the target image P0 on the sheet 92 under one adoption condition selected from the plurality of printing conditions (see FIG. 8). The target image P0 is an image to be printed.

The details of the test printing process and the main printing process will be described later.

[Image quality confirmation print control]
When a predetermined start operation is performed on the operation device 3a, the job control unit 5a starts the image quality confirmation print control.

Hereinafter, an example of the procedure for image quality confirmation print control will be described with reference to the flowchart shown in FIG. In the following description, S1, S2, ... Represents identification codes for a plurality of steps in the image quality confirmation print control.

<Step S1>
In step S1, the job control unit 5a executes a process of acquiring the target image P0 (see FIG. 8). After that, the job control unit 5a shifts the process to step S2.

For example, the job control unit 5a acquires the read image data Di0 as the data of the target image P0 by causing the image reading device 1 to execute the reading process.

Further, the job control unit 5a may acquire the print job data from the other device through the communication device 4. In this case, the print job data is the data of the target image P0.

Further, the job control unit 5a may acquire the image data previously stored in the secondary storage device 53 as the data of the target image P0.

The job control unit 5a that executes the process of step S1 is an example of an image acquisition unit that acquires the image P0 to be printed.

<Process S2>
In step S2, the parameter setting unit 5b executes the test method setting process. After that, the parameter setting unit 5b shifts the process to step S3.

The test method setting process is a process of setting the number of test images P1 and the types of a plurality of test images P1 according to the operation for the operation device 3a.

For example, the parameter setting unit 5b causes the display device 3b to display the test method selection screen g1 as shown in FIG. 3 in step S2. The test method selection screen g1 includes a number selection menu g11 and a type selection menu g12. Further, the test method selection screen g1 also includes a partial area selection menu g13.

The number selection menu g11 includes a plurality of operation icons for selecting the number of test images P1 from a plurality of predetermined candidates. The type selection menu g12 includes a plurality of operation icons for selecting the type of the test image P1 from a plurality of predetermined candidates.

In the example shown in FIG. 3, there are three candidates for the number of test images P1: 4, 6, and 8. Similarly, there are three types of test image P1 candidates: a reduced image, a divided image, and a representative image. It is also conceivable that the candidate for the type of the test image P1 includes only a part of the reduced image, the divided image, and the representative image.

As shown in FIG. 5, the reduced image is an image in which the entire target image P0 for one page is reduced. Therefore, when the reduced image is selected as the type of test image P1, a plurality of the same test images P1 are formed on the sheet 92.

Further, as shown in FIG. 6, the divided image is an image of a plurality of compartment areas in the target image P0. When the divided image is selected as the type of the test image P1, a plurality of different test images P1 are formed on the sheet 92.

The parameter setting unit 5b that executes the process of step S2 is an example of a type setting unit that sets the types of a plurality of test images P1 according to the operation on the operation device 3a.

In the present embodiment, when the divided image is selected as the type of the test image P1, the number selected by the number selection menu g11 is the number of divisions of the test image P1, that is, the number of divisions of the test image P1.

Further, as shown in FIG. 7, the representative image is an image of one partial region in the target image P0. Therefore, when the representative image is selected as the type of test image P1, a plurality of the same test images P1 are formed on the sheet 92.

The partial area selection menu g13 is effective when the representative image is selected as the type of the test image P1. The partial area selection menu g13 includes a plurality of operation icons for selecting the partial area for extracting the test image P1 from the target image P0.

In the example shown in FIG. 3, the selection candidates of the partial area in the partial area selection menu g13 are seven predetermined areas. However, it is also conceivable that the parameter setting unit 5b specifies the coordinates of the partial region according to the operation on the operating device 3a.

As will be described later, regardless of the type of the test image P1, the plurality of test images P1 are formed on the sheet 92 by the printing process under the different printing conditions.

<Process S3>
In step S3, the parameter setting unit 5b selects one designated image quality from a plurality of predetermined image quality candidates according to the operation on the operation device 3a. After that, the parameter setting unit 5b shifts the process to step S4.

Each of the plurality of image quality candidates is associated with one or more of the print parameters in advance. The parameter setting unit 5b that executes the process of step S3 is an example of the designated image quality selection unit.

For example, the parameter setting unit 5b causes the display device 3b to display the image quality selection screen g2 as shown in FIG. 4 in the step S3. The image quality selection screen g2 includes a plurality of image quality selection icons g21 corresponding to the plurality of image quality candidates.

In the example shown in FIG. 4, the plurality of image quality candidates include vivid tone image quality, dark tone image quality, sharp image quality, blur image quality, dark image quality, and light image quality. One selected from these plurality of image quality candidates is the designated image quality.

The plurality of image quality candidates are associated with one or more print parameters in advance. For example, the image quality of the vivid tone, which means a vivid image, is associated with the print parameters such as saturation, density and hue.

<Process S4>
In step S4, the parameter setting unit 5b automatically sets a plurality of printing conditions corresponding to the designated image quality selected in step S4. The plurality of print conditions consist of a combination of a plurality of candidate values for one or more print parameters corresponding to the designated image quality.

For example, it is conceivable that each of the image quality candidates is associated with a predetermined number of candidate conditions equal to or greater than the maximum number of test images P1. The plurality of candidate conditions are candidates for the plurality of printing conditions. In this case, the parameter setting unit 5b randomly selects the same number of printing conditions as the number of test images P1 from the plurality of candidate conditions, or according to a predetermined priority.

For example, a plurality of vivid tone candidate conditions including a combination of a plurality of candidate values of the saturation, a plurality of candidate values of the density, and a plurality of candidate values of the hue correspond to the image quality of the vivid tone. It is assumed that the conditions are predetermined as a plurality of candidate conditions. In this case, the parameter setting unit 5b selects the plurality of printing conditions corresponding to the image quality of the vivid tone from the plurality of vivid tone candidate conditions.

The parameter setting unit 5b shifts the process from the process S4 to the process S5. The parameter setting unit 5b that executes the process of step S4 is an example of the print condition setting unit that automatically sets the plurality of print conditions.

<Process S5>
In step S5, the image data processing device 54 generates test image data representing the plurality of test images P1 corresponding to the plurality of printing conditions and the identification information D0 of the plurality of printing conditions (FIGS. 5 to 7). reference).

As shown in FIGS. 5 to 7, the test image data represents an image including a plurality of test images P1 and a plurality of identification information D0 associated with the plurality of test images P1. The data of each of the test images P1 is generated according to the candidate values of one or more of the printing parameters such as the saturation or the density in any one of the plurality of printing conditions.

Further, the test image data represents an image in which a plurality of test images P1 are aggregated on one page of the sheet 92. The image data processing device 54 shifts the processing from the process S5 to the process S6.

<Step S6>
In step S6, the job control unit 5a causes the print processing apparatus 2 to execute the print process based on the test image data. As a result, as shown in FIGS. 5 to 7, an image including a plurality of test images P1 and identification information D0 of the plurality of printing conditions corresponding to the plurality of test images P1 is formed on the sheet 92.

For example, when the reduced image is selected as the type of the plurality of test images P1, an image as shown in FIG. 5 is formed on the sheet 92. Further, when the divided image is selected as the type of the plurality of test images P1, an image as shown in FIG. 6 is formed on the sheet 92. Similarly, when the representative image is selected as the type of the plurality of test images P1, an image as shown in FIG. 7 is formed on the sheet 92.

As described above, the test image data represents an image including a plurality of test images P1 corresponding to the plurality of printing conditions and identification information D0 of the plurality of printing conditions corresponding to the plurality of test images P1. ..

That is, in steps S5 and S6, the image data processing device 54 and the job control unit 5a cause the printing processing device 2 to execute the test printing process. In the test printing process, a plurality of test images P1 based on the target image P0 are formed on the sheet 92 under the plurality of printing conditions, and identification information D0 of the plurality of printing conditions corresponding to the plurality of test images P1 is generated. This is a process of forming on the sheet 92.

In the present embodiment, the image data processing device 54 and the job control unit 5a cause the printing processing device 2 to execute a process of aggregating and forming a plurality of test images P1 on one page of the sheet 92 in the test printing process.

The image data processing device 54 and the job control unit 5a that execute the processes of steps S5 and S6 are examples of the test print control unit. The job control unit 5a shifts the process from the process S6 to the process S7.

<Step S7>
In step S7, the parameter setting unit 5b executes a process of selecting one of the plurality of printing conditions as an adoption condition or a reference condition according to the operation on the operating device 3a.

The adoption condition is a printing condition that specifies the value of one or more of the printing parameters adopted for printing the target image P0 in the main printing process. The reference condition is a printing condition that serves as a reference for setting the plurality of printing conditions adopted for printing the plurality of test images P1 in the next test printing process.

Specifically, when the parameter setting unit 5b detects that a predetermined operation for designating one of the plurality of identification information D0 as the adoption condition has been performed on the operation device 3a, the plurality of identification information D0. One of the print conditions corresponding to the specified identification information D0 is selected as the adoption condition.

Similarly, when the parameter setting unit 5b detects that a predetermined operation for designating one of the plurality of identification information D0 as the reference condition has been performed on the operation device 3a, the plurality of prints are performed. One of the conditions corresponding to the specified identification information D0 is selected as the reference condition.

Then, the parameter setting unit 5b shifts the process to the step S8 when the adoption condition is selected, and shifts the process to the step S10 when the reference condition is selected.

The parameter setting unit 5b that executes the process of step S7 selects one of the plurality of printing conditions as the adoption condition according to the operation of designating one of the plurality of identification information D0 for the operation device 3a. This is an example of a selection unit.

Further, the parameter setting unit 5b that executes the process of step S7 follows the operation of designating one of the plurality of identification information D0 for the operating device 3a, and according to the operation of designating one of the plurality of printing conditions. It is also an example of a reference condition selection unit that selects one of the printing conditions as the reference condition.

<Step S8>
In step S8, the image data processing device 54 generates the printed image data representing the target image P0 corresponding to the adoption conditions (see FIG. 8). After that, the image data processing device 54 shifts the processing to step S9.

The present print image data is generated according to the candidate values of one or more of the print parameters such as the saturation or the density under the adoption conditions.

<Process S9>
In step S9, the job control unit 5a causes the print processing apparatus 2 to execute the print process based on the print image data. After that, the job control unit 5a ends the image quality confirmation print control.

By the process of step S9, as shown in FIG. 8, the target image P0 is formed on the sheet 92 by the printing process under the adoption conditions.

That is, in steps S8 and S9, the image data processing device 54 and the job control unit 5a cause the print processing device 2 to execute the main printing process. The main printing process is a process of forming the target image P0 on the sheet 92 under the above-mentioned adoption conditions.

The image data processing device 54 and the job control unit 5a that execute the processes of steps S8 and S9 are examples of the print control unit.

<Step S10>
In step S10, the parameter setting unit 5b automatically resets the plurality of printing conditions based on the reference conditions. The plurality of printing conditions reset in the step S10 include conditions different from the plurality of printing conditions set in the step S4.

For example, consider a case where the possible value of the specific parameter, which is one of the plurality of print parameters, is a value in nine stages from rank 1 to rank 9. Then, in step S4, it is assumed that rank 1, rank 3 and rank 5 of the specific parameter are set as the plurality of candidate values.

Then, it is assumed that the value of the specific parameter in the reference condition is the rank 3. In this case, in step S10, the parameter setting unit 5b uses the rank 3 which is the value of the specific parameter in the reference condition and the ranks 2 and 4 closest to the rank 3 to be used next. It is conceivable to reset as a plurality of candidate values of the specific parameter in the printing conditions.

Then, the parameter setting unit 5b resets the plurality of printing conditions to be used next, and then shifts the process to step S5. As a result, the test printing process corresponding to the plurality of reset printing conditions is executed (S5, S6).

The parameter setting unit 5b that executes the process of step S10 is an example of the print condition resetting unit.

As shown above, if the image forming apparatus 10 is adopted, the plurality of printing conditions corresponding to the designated image quality are automatically set only by the user selecting the designated image quality (FIG. 2). Steps S3 and S4). Further, a plurality of test images P1 corresponding to the set plurality of printing conditions are formed on the sheet 92 (steps S5 and S6 of FIG. 2). Therefore, the user can easily set the intended printing conditions while checking the output plurality of test images P1.

Further, the user can select one of the plurality of printing conditions as the reference condition, and the parameter setting unit 5b automatically resets the plurality of printing conditions based on the reference condition. (Step S10 in FIG. 2).

Therefore, the user selects one of the reference conditions that is relatively close to the intended image quality among the plurality of print conditions that are initially set, and further for the other print conditions that are close to the reference conditions. A plurality of test images P1 can be confirmed. As a result, the user can easily set the printing conditions for obtaining the printed matter of the target image P0 closer to the intended image quality.
