发明名称 Method for correcting density unevenness for a recording head and an image formation apparatus provided with such a method
摘要 An image formation apparatus provided according to the present invention does not generate any printing density streaks in low density areas of an image and is therefore capable of outputting stabilized images without any density unevennesses and density streaks in any tonality. The apparatus is structured so as to correct density signals in accordance with a correction table 1 for indicating the recording characteristics of each of the recording elements of the head and the recording characteristics indicated by this correction table 1, and to drive the recording head in accordance with a correction table 2, which does not allow the fore-going corrections to be made when the density signals are lower than a given density, and the density signals corrected by this correction table 2.
