Further, at the time of automatic selection, the name of the profile automatically selected is displayed in the name display area 634 so as to line up and down with the output color profile selection list 632 displaying “automatic selection”.

The matching method selection list 633 displays a method for correcting the color difference of the image to be printed. For example, there are various correction methods such as maintaining a relative color gamut.
Next, the operation of the print control apparatus 11 will be described.

  Now, at the time of printing, a printing application is activated in the CPU 20 of the printing control apparatus 11. Then, the print setting screen 30 shown in FIG. 2 is displayed on the display unit 14 by display control via the display control unit 28. Here, normally, various print setting contents (output conditions such as printer and paper type) in the printer setting column 61 and the color setting column 63 are the contents of basic settings set in advance. Therefore, when the print button 80 is pressed as it is, the image of the pre-display image 100 displayed at that time in the layout window 40 of the print setting screen 30 is printed according to the basic setting output condition.

  On the other hand, if it is desired to print on other paper (for example, postcard) listed in the paper type selection list 612 instead of the basic paper (for example, plain paper) this time, on the print setting screen 30, for example. , The desired paper (postcard) is selected from the paper type selection list 612 in the printer setting column 61. In association with this, the paper size selection list 613, the paper feed method selection list 614, and the like are opened, and the respective setting contents are matched with the setting contents adapted to the printing of the selected paper (postcard). Then, when the user presses the print button 80 after that, the image of the pre-display image 100 is printed on the paper (postcard) desired for the current printing.

  In addition, when printing on a special printing medium (for example, “Japanese paper”) that is not described in the paper type selection list 612 this time, the custom setting is made from the paper type selection list 612 in the printer setting column 61 on the print setting screen 30. The paper type setting 90 is selected. Then, since the custom paper type setting window 90a shown in FIG. 4 is displayed, the user can select any desired paper type (a kind of output condition). In this regard, the CPU 20 that causes the display unit 14 to display the print setting screen 30 including the paper type selection list 612 that can select the paper type as an output condition at the time of printing is displayed on the display unit 14 via the display control of the display control unit 28. The processing step of the CPU 20 in this case corresponds to an output condition selection step.

  When the custom paper type setting window 90a is displayed, the name of a special printing medium desired as the current printing medium (hereinafter referred to as “special medium”) is selected in the name entry field 901 by the user. Entered as output conditions. Then, a color profile adapted to the special medium is selected and set from the output ICC profile list 906, and parameters of the drive system such as ink density adapted to the special medium are operated by the ink density slider 907 or the like. It is set based on. Then, the setting contents are stored in the storage unit 24 and the profile storage unit 26 under the control of the CPU 20. In this respect, a custom paper type setting window 90a capable of setting printing parameters (color profile and driving system parameters) adapted to the special medium (Japanese paper) which is the output condition selected by the user is displayed on the display unit 14. The CPU 20 functions as a parameter setting unit, and the processing steps of the CPU 20 in this case correspond to parameter setting steps.

  Next, when the OK button 912 is pressed by the user in the custom paper type setting window 90a, the CPU 20 selects the special medium whose name is entered in the name entry field 901 and the color selected from the output ICC profile list 906. Link profiles and set drive system parameters. That is, print setting information in which the special medium that is the selected output condition, the color profile that is the set parameter, and the drive system parameter are associated is created, and the print setting information is stored in the storage unit 24. Register with a printing application. In this respect, the CPU 20 that registers the print setting information that associates the selected output condition with the set parameter in the application functions as a registration unit, and the processing step of the CPU 20 in this case corresponds to the registration step.

  Then, after the registration of the print setting information related to printing on the special medium as described above is completed, when the print button 80 is pressed, the special medium desired by the user is applied to the special medium. The color difference is corrected using the color profile, and printing is performed with an appropriate ink density and drying time set. Thereafter, when printing using the same medium as the current special medium as an output condition, the printing parameters suitable for the special medium are already registered in the application in the custom paper type setting window 90a. It is not necessary to perform the same print setting operation.

In addition, the color profile may be automatically selected as follows.
As shown in FIG. 5, when automatic selection is selected in the output color profile selection list 632, the profile processing unit 27 follows the settings of the printer selection list 611 and the paper type selection list 612 based on the control of the CPU 20. One suitable color profile is searched from 26 and selected. Then, the name of the selected color profile is displayed in the name display area 634 on the print setting screen 30. In this regard, the processing step of the CPU 20 that automatically selects one color profile from the profile storage unit 26 based on the output condition such as the paper type corresponds to the profile selection step. Incidentally, at that time, if the printing parameters suitable for the special medium are already registered in the application in the custom paper type setting window 90a, the color profile included in the registered print setting information is also searched. Automatically selected.

  Here, the color profile is a profile defined based on respective conditions such as the type of printer to be output, the type of paper to be printed, and the type of ink that is a printing material. Therefore, in the present embodiment, the profile processing unit 27 selects a printer type from the printer selection list 611 and a paper type from the paper type selection list 612, so that the profile processing unit 27 is a color profile suitable for the above two conditions. Is selected from the profile storage unit 26 and the application. Then, the color difference correction using the color profile automatically selected as described above is performed based on the control of the CPU 20, and the printing unit 15 executes printing on the selected paper. In this respect, the processing step of the CPU 20 that controls the correction of the color difference of the image during printing using the selected color profile corresponds to a control step.

  The output color profile selection list 632 also displays color profiles stored in the profile storage unit 26 in addition to “automatic selection” indicating that a color profile is automatically selected. The user can also select a profile arbitrarily. When arbitrarily setting a color profile, the name of the selected color profile is displayed in the output color profile selection list 632 and the name display area 634 is not displayed. When the name display area 634 is hidden, the matching method selection list 633 is displayed immediately below the output color profile selection list 632 and displayed.

According to the above embodiment, the following effects can be obtained.
(1) A color profile adapted to the paper type (output condition) at the time of printing, without having to repeatedly apply and input printing parameters for each output condition such as paper type each time printing is performed. The printing unit 15 is controlled based on the print setting information registered in the application in association with the print parameters. Therefore, it is possible to simplify the work procedure when printing an image on a sheet and reduce the labor of printing.

  (2) The print setting screen 30 displays the name of the color profile used for color difference correction in addition to the printer and paper type used for the current printing. Therefore, when printing an image on paper, the user can easily check the print setting information used at the time of printing on the print setting screen 30.

  (3) On the print setting screen 30, printing parameters (color profile and driving system parameters) adapted to the printer and paper type used for the current printing can be easily set by operating the operation unit 13. Therefore, when the output conditions at the time of printing differ due to differences in printing devices such as the printing unit 15 or media such as plain paper or postcards, image color differences that occur between these devices and between media can be easily corrected. Therefore, the labor of printing can be reduced in this respect.

  (4) Since a suitable profile can be automatically selected based on the output conditions set in the printer selection list 611 and the paper type selection list 612, it is possible to save time and effort for selecting a color profile each time printing is performed. . Furthermore, even a user who is not familiar with the setting of the color profile can cause the printing unit 15 to print an image with the color difference of the image suppressed.

  (5) Since the name of the profile selected at the time of automatic selection is displayed in the name display area 634 in the output color profile selection list 632, the name of the profile automatically selected can be easily recognized.

  (6) When a color profile is automatically selected, information indicating that the color profile is automatically selected and the name of the automatically selected color profile are displayed side by side on the print setting screen 30. Therefore, the user can easily confirm at a glance from the print setting screen 30 that the color profile to be used is automatically selected and the name of the color profile thus selected.

  (7) When the user arbitrarily selects a color profile in the output color profile selection list 632, the name display area 634 is not displayed. Therefore, the name of the selected color profile is not displayed in both the output color profile selection list 632 and the name display area 634. Therefore, information displayed on the print setting screen 30 can be reduced.

  (8) The printer selection list 611 and the paper type selection list 612 for setting the output conditions are displayed on the print setting screen 30 on which the name display area 634 for displaying the name of the color profile automatically selected is displayed. Therefore, the name of the color profile to be automatically selected and the output condition can be easily confirmed on the same screen.

In addition, you may change the said embodiment as follows.
In the above embodiment, the printing parameters constituting the print setting information in association with the output condition such as the paper type may include at least the color profile among the color profile and printer drive system parameters. Only the profile may be used.

  In the above embodiment, the parameters of the drive system that constitute the printing parameters together with the color profile may include parameters other than ink density, drying time, paper thickness, and platen gap. For example, it may include paper feed correction for paper transport, suction force for paper suction transport, cut adjustment for roll paper cutting, paper discharge settings for paper discharge, roll paper back tension for tension during roll paper transport, etc. Or at least one parameter including these.

  In the above embodiment, the output condition that configures the print setting information registered in the application in association with the parameter (color profile, etc.) may be at least one of the printer type and the paper type, not necessarily both. Also good.

In the above-described embodiment, the area setting in the screen such as the layout window 40 and the setting window 60 on the print setting screen 30 is not limited to that of the present embodiment but is arbitrary.
In the above embodiment, the output condition that is an adaptation criterion when the profile processing unit 27 automatically selects a color profile from the profile storage unit 26 is not limited to the type of printer and the type of paper. For example, the type of printing agent (ink) used may be used as the output condition.

  In the above embodiment, the name display area 634 need not be displayed immediately below the output color profile selection list 632. That is, the name display area 634 and the output color profile selection list 632 do not have to be displayed side by side, and are sufficient if they are on the print setting screen 30.
