摘要

An apparatus is provided that prints on a printing medium while a head having nozzles that discharge ink moves relative to the printing medium. The apparatus includes a unit capturing image data to be a target of N-valued processing (N is a natural number of N>=2), a unit capturing input/output characteristics information showing the correspondence between input image data (before N-valued processing for every line), and output image data (image data after each piece of the input image data is subjected to N-valued processing), a unit correcting the image data before N-valued processing based on the acquired input/output characteristics information, a unit performing N-valued processing on the corrected image data, a unit converting the N-valued processed image data into printing data, and a unit executing printing based on the printing data.
