Printing apparatus, control method, printing system, and storage medium

A method of controlling a printing apparatus, the method comprising:

• obtaining print data in which in imposition image data in which one or more images are imposed in a print region, a code for identifying each image in the imposition image data is embedded;
• determining an ink color to be used to print the code by excluding an ink color satisfying a predetermined condition from candidates for the ink color to be used to print the code;
• and
• controlling printing of the code based on the print data obtained by the obtaining using a plurality of nozzle arrays for the ink color determined by the determining.

A non-transitory computer readable storage medium storing a program which causes a computer to comprise:

• an obtaining unit configured to obtain print data in which in imposition image data in which one or more images are imposed in a print region, a code for identifying each image in the imposition image data is embedded;
• a determination unit configured to determine an ink color to be used to print the code by excluding an ink color satisfying a predetermined condition from candidates for the ink color to be used to print the code;
• and
• a print control unit configured to print the code based on the print data obtained by the obtaining unit using a plurality of nozzle arrays for the ink color determined by the determination unit.

A printing system comprising an information processing device and a printing apparatus,

• the information processing device comprising:
• a code generation unit configured to generate a code for identifying each image in imposition image data in which one or more images are imposed in a print region;
• a print data generation unit configured to generate print data such that the code is arranged based on the code generation unit;
• and
• an output unit configured to output to the printing apparatus the print data generated by the print data generation unit,
• the printing apparatus comprising:
• an obtaining unit configured to obtain the print data in which the code is embedded;
• a determination unit configured to determine an ink color to be used to print the code by excluding an ink color satisfying a predetermined condition from candidates for the ink color to be used to print the code;
• a print control unit configured to print the code based on the print data obtained by the obtaining unit using a plurality of nozzle arrays for the ink color determined by the determination unit;
• and
• an inspection unit configured to read a printed subject to perform an inspection using the code.
