Abstract:
1. An image-forming device, comprising: a printing unit that is capable of printing images; an image-density characteristics determining unit that determines image-density characteristics of an image desired to be printed on a recording medium by the printing unit; a patch density setting unit that dependent upon a result of the image-density characteristics determining unit sets patch density data based on the determined image-density characteristics of the desired image; a patch generating unit that controls the printing unit, based on the patch density data set by the patch density setting unit, to generate a plurality of measurement patches; a density measuring unit that measures densities of the measurement patches generated by the patch generating unit; a correcting unit that performs density correction on image data indicative of the desired image according to the densities of the measurement patches measured by the density measuring unit; and a print controlling unit that controls the printing unit to print the desired image on the recording medium based on the image data corrected by the correcting unit.
