Printing device, printing device control program, printing device control method, printing data producing device, printing data producing program, printing data producing method, correction information producing method, and correction information producing device

A printing device including a printing head having arranged printing elements capable of forming dots on a medium used for printing, the printing device printing an image by forming dots on the medium by the printing head, the printing device comprising:

• an image data obtaining unit that obtains image data including pixel data corresponding to a plurality of pixels forming the image;
• a correction information storage that stores correction information, the correction information being produced based on the density change of dots formed by the printing head for pixel data having the same value in the arrangement direction of the printing elements and being used for correcting the density change characteristic of each of the printing elements;
• a printing data producing unit that produces printing data that defines information related to a dot forming content by each of the printing elements corresponding to the image data;
• and
• a printing unit that prints the image on the medium by the printing head based on the printing data,
• the printing data producing unit producing printing data based on the image data and the correction information so that a line graph representing the density change characteristic of a printing result by the printing head draws a line with a gradient.
