Claim Text:
1. A printing apparatus that conveys a print medium and performs printing on the conveyed print medium, the printing apparatus comprising: a processor and a memory; a print data generation unit configured to generate print data by quantizing image data to be printed in which predetermined pseudo halftone processing of the image data is performed; a pattern data generation unit configured to generate print data of a detection pattern by quantizing data of the detection pattern in which the same predetermined pseudo halftone processing of the data on the detection pattern is performed; a pattern printing unit configured to print a detection pattern based on the generated print data of the detection pattern; a measuring unit configured to measure the printed detection pattern, the measuring unit being placed downstream of the pattern printing unit in a conveying direction of the print medium; an image printing unit configured to print an image based on the print data of the image data that is generated by the print data generating unit, the image printing unit being placed downstream of the measuring unit in the conveying direction of the print medium; and a print control unit configured to control printing by the image printing unit based on a measurement result of the detection pattern by the measuring unit, wherein the print data generation unit, the pattern data generation unit, the pattern printing unit, the measuring unit, the image printing unit and the print control unit are implemented at least in part by the processor and the memory.
