PURPOSE:To increase the expression tones of charge controlled ink jet recording by changing the quantities of partial overlapping of dots, separation of dots, etc. of deflection directions. CONSTITUTION:The dot pitch D1, D2, is treated as the standard. In this case at every stage of electric charge, a charge voltage is changed within a specified extent wherein a deflection sliding less than 1 dot pitch is given, and by introducing a sliding which is less than 1 pitch from a standard pitch the numbers of expression tones are increased. By the above, the recording concentrations of a' and b' that have upward slidings by the half pitch d become the contentrations between the recording concentrations of (a) and (b), and the recording concentrations of (b) and (c). By introducing a half pitch sliding of upward or downward only or further by introducing upward or downward pitch sliding of other than a half pitch, the numbers of expression tones can be further increased. |
