Abstract

PURPOSE: To make it possible to elevate the density reproductiveness of the final recording medium, by compensating a fault of physical response characteristic which a nozzle system has, by the digital signal processing, in case of ink-jet recording.
CONSTITUTION: Three primary colors of the input signals Rl, Gl and Bl are input to the image recording device representing the picture elements of an image by the dot matrix in which several dots are arrayed, and the conversion circuit 501 which converts those signals Rl, Gl and Bl to the subtraction three primary color signals Cl, Ml and Yl of the corresponding cyan, magenta and yellow is provided. The signals Cl, Ml and Yl which have been converted in the above circuit 501 are provided to the table memroy 502, in this memory 502 is set an otpional voltage level to the dot co-ordinates of m2 pieces each by the matrix tables which have been prepared beforehand separately for each level l of the signals Cl, Ml and Yl, and the output is provided to the voltage conversion circuit 503. And the density reproductiveness of the recording medium 505 is elevated by referring to the table of the memory 502 for each input signal level.
