Printer with correction data for number of tones which is fewer than number of tones that image data have

摘要

A printer apparatus comprises a head having k (number) printing elements for printing an image data. A printing element selecting section selects a printing element driven at the time of printing among the k printing elements of the head. An image correcting section is a section for correcting the image data previous to the printing of the image data using the head, and comprises a correction data memorizing section for memorizing a correction data for a certain single tone among n (number) tones that the image data has for each of the printing elements, a tone detecting section for detecting the tone of the image data corresponding to each of the selected printing elements of the head, and a correction data generating section for generating a correction data for each of the selected printing elements, corresponding to the tone detected by the tone detecting section, by using the correction data memorized in the correction data memorizing section.
