Abstract:
A recording material obtained by performing an ink jet recording method utilizing plural ink discharge means for discharging ink onto a recording medium to form an image, said plural ink discharge means discharging plural kinds of ink each with a different density, respectively, said method comprising the steps of:converting an input image density signal into either an output image density signal for driving a first ink discharge means for a first ink density or an output image density signal for driving a second ink discharge means for a second ink density, in accordance with an amplitude of said input image density signal at which recording is performed with two kinds of ink each having a different density;converting the output image density signal into binary data;inverting binary data converted in said converting step;distributing the binary data inverted in said inverting step and the binary data to be inverted into first drive data for said first ink discharge means for said first density and second drive data for said second ink discharge means for said second density; anddriving said plural ink discharge means based on the first and second drive data distributed to perform a recording operation.
