Abstract

See full text

A density difference correction signal is generated for correcting a density difference upon forward path printing and backward path printing by density difference correction signal generating apparatus to store the generated density difference correction signal in an unevenness correction RAM. A predetermined correction line in a HS table memory is selected depending upon the density difference correction signal. By the selected correction line, the density correction of the image data of forward path printing and backward path printing is performed to output the image data.
