ABSTRACT:
A printer includes: a print head including a plurality of nozzles capable of printing dots of different sizes; a test-pattern forming section that forms test patterns each have only one dot size; a test-pattern printing section that prints the test patterns formed by the test-pattern forming section for each nozzle of the print head; an output-density reading section that optically reads the test patterns printed by the test-pattern printing section to determine the output densities of the test patterns; an input and output density-characteristic information generating section that generates input-and-output density information indicative of the relationship between the output densities read by the output-density reading section and the input densities of each test pattern formed by the test-pattern forming section; an input-density correcting section that corrects the input density of each nozzle of the print head on the basis of the input-and-output density information generated by the input and output-density-characteristic-information generating section; and a printing section that executes printing using the input densities corrected for each nozzle by the input-density correcting section.
