PRINTING POSITION ADJUSTING METHOD FOR IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a printing position adjusting method for an image forming device performing correction adjustment not only on black(B) reference but also between cyan (C) and magenta(M). SOLUTION: In this image forming device, printing deviation is avoided by acquiring correction values on the printing positions of three colors with black(B) as reference, acquiring a correction value on the deviation of the printing position between magenta(M) and cyan(C) being conspicuous colors thereafter and adjusting the printing position by using both correction values. The image forming device having more excellent printing quality by performing the correction between magenta(M) and cyan(C) being the conspicuous colors especially is realized.
