ABSTRACT:
An ink jet printer apparatus includes a print head and a color correction processor. The print head is scanned relatively to a recording medium in a main scan direction and an auxiliary scan direction which is perpendicular to the main scan direction. The print head comprises recording heads of M which are arranged in the main scan direction while displaced from one another at an interval of L dots in the auxiliary scan direction, each of the recording heads having color recording elements of N. When in an interleave operation, every scanning operation, the recording heads of M perform an auxiliary feeding operation at an interval of P dots at (K-1) times and then perform an auxiliary feeding operation at an interval of S dots once, P/K is set as an irreducible fraction, P is set to an integer smaller than N.multidot.K/(K-1) and S is set to K.multidot.N-P(K-1), and when M>1, for M.ltoreq.K and L.multidot.M.ltoreq.K, L is set to a positive integer and the recording heads are arranged while displaced from one another at an interval of L dots in the auxiliary scan direction. Alternatively, when M.ltoreq.K and L.multidot.M>K, L is set to a positive integer, and the recording heads are arranged while displaced from one another at the interval of L dots so that L/N is equal to an irreducible fraction. The color correction processor supplies print data to the print head. The color correction processor performs color correction processing suitable for the recording order of the color recording elements on image signals to be recorded.
