ABSTRACT:
A pattern (B) printed by driving only a specific recording element different from a pattern (A) for implementing head-shading is simultaneously formed and the address of density data on the pattern (B) for detecting the position of a recording element in a memory is used to correlate the density data on the pattern (A) for detecting uneven density for each recording element. The implementation of such head-shading and the identification of the position of the recording element of the recording head can thus be carried out with accuracy. As the position of the recording element and the density data thus detected are accurately correlated at all times, improvements in head-shading can be effected accordingly.
