PROBLEM TO BE SOLVED: To make it possible to print a density irregularity-free and high quality level image by comparing the density of the image with a reference density per specified unit, based on the density distribution of the image recorded experimentally and selecting a signal of the type close to the reference density to be sent to a printing head. SOLUTION: When correcting plural recording elements and a recording head IJH with data storing memory 13, plural various signals are applied to the recording elements to make a recording medium record plural recording patterns experimentally. Further, a recording pattern image recorded is read using a CCD camera 4 and one signal is selected from among the plural various signals based on the density distribution of the image so that the recording pattern image is of a value equal to a reference density per specified unit of the recording element. Data for selecting this signal is used as correction data and is stored in memory 13 as initial correction data. After that, either of optical correction data per specified unit of the recording element or the initial correction data is selected, and data based on the selected data is sent to the recording head IJH. |
