ABSTRACT:
A color registration-pattern formed between continuous printing pages with different magnifications is read so as to correct color misalignment by converting the magnification into the reference magnification so as to calculate the present color misalignment correction.Thereby, a plurality of the color registration-patterns with different magnifications, which are formed between continuous printing pages with differentiated magnifications by the speed change of a polygon-mirror motor can be read so as to correct the color misalignment.
