PROBLEM TO BE SOLVED: To provide a recording device capable of performing recording of high quality by carrying out accurate detailed conveyance control over an actually used recording medium in an ink jet printer.SOLUTION: A test pattern with a long cycle is printed through first scanning in ongoing and return ways by utilizing nozzle intervals. A candidate for a correction value is selected therefrom, a test pattern with a short cycle is recorded using values before and after the candidate, and a sensor reads the density of the test pattern. An approximate expression is used for a value obtained by reading the test pattern with the short cycle, and a correction is determined at a value of a minimum resolution unit closest to a peak of an approximated line. Conveyance is carried out using such a correction value so as to record an image where dot deviation is suppressed. |
