Abstract:
An ink jet recording apparatus that performs recording by ejecting inks using a recording head, the apparatus comprising:first storage means for storing inks containing colorants;second storage means for storing liquid which does not contain any colorants;ink generating means for generating inks having different densities and belonging to the same color family as that of said ink stored in said first ink storage means, said ink generating means generating inks by respectively mixing the inks stored in said first storage means and the liquid containing no colorants stored in said second storage means;detection means for detecting densities of inks generated by said ink generating means; andcontrol means for controlling recording with the mixed inks through the recording head, wherein selective ejection of the mixed inks is carried out responsive to detected densities by said detection means in the mixed inks and responsive to recording data.
