Printing apparatus, method for controlling printing apparatus, and computer-readable storage medium

A printing apparatus, comprising:

• a head including:
• first nozzles for printing an image based on image data in inks in basic colors on a printing medium;
• second nozzles for printing an image based on the image data in an ink in a custom color different from the basic colors on the printing medium;
• first driving element causing the inks to be discharged through the first nozzles;
• and
• second driving element causing the ink to be discharged through the second nozzles;
• first flow path tubes for supplying the inks in the basic colors to the first nozzles;
• at least one second flow path tube for supplying the ink in the custom color to the second nozzles, and
• a controller configured to:
• before loading the at least one second flow path tube with the ink in the custom color, acquire a first printing color gamut, the first printing color gamut being a gamut including the custom color within a printing color gamut in a predetermined color space, the printing color gamut being a gamut including color values of colors printable in the inks in the basic colors and the custom color, and
• after acquiring the first printing color gamut and after loading the at least one second flow path tube with the ink in the custom color, operate the first driving elements and the second driving elements to print patches for first imaging color values, the first imaging color values being color values falling within the first printing color gamut among color values in the image data.
