PURPOSE:To reduce the change in chromaticity caused by misalignment by applying many kinds of threshold matrixes to each ink. CONSTITUTION:The threshold matrixes are formed with the combination of a threshold matrix where a screen angle theta is 45-90 deg., a threshold matrix where the former threshold matrix is inverted in the main scanning direction or the subscanning direction (screen angle theta'=90 deg.-theta), and a threshold matrix having at least one of screen angles 45 deg. and 90 deg.. The change in color caused by the misalignment is reduced in the full color recording method by the dot printer system by using the threshold matrix above.
