PURPOSE:To obtain the optioned device which always gives pictures excellent in balance of color by a method wherein there are provided a recording head part for discharging drops of multicolor ink and forming recording pictures, a color concentration detector for each color of the pictures and a concentration-adjusting means for each color by detective signals. CONSTITUTION:Three recording heads 103Y, 103M, 103C for jetting ink of respective colors of yellow Y, magneta M, cyan C are provided on a rotative drum which winds a recording medium 101 like paper or the like rotates in an intended direction and at a constant speed in synchronization with a recording signal. They are operated through a driving circuit 104. The optical concentration of the ink attached on the recording medium 101 is detected by a color concentration-detecting means 105 and supplied to the driving circuits 104Y, 104M, 104C fixed on each of the recording heads 103 through a color concentration-adjusting circuit 106 in accordance with these detecting signals. In this manner, the balance of color is adjusted to form a color picture by the recording head 103 in accordance with video signals SY, SM, SC. |
