Abstract
An ink jet recording apparatus which performs recording using a plurality of types of inks which are different in nature such as level of thickness, improved to attain excellent gradation of recorded image with a reduced number of ink types which are prepared beforehand. In one form, a clear ink which does not contain any dye is mixed with an ink which contains dye so as to form an ink blend of a density which can be set by varying the mixing ratio. The ink blend thus formed is supplied to a recording head. The invention also provides an ink jet recording apparatus which permits inks of different compositions to be blended within the recording apparatus so a to enable selection of ink composition which is optimum for the image to be recorded or purpose of use.
