摘要： An ink-jet head driver comprises: a pressure chamber filled with a recording liquid; a piezo-electric element as electrical/mechanical transducing means for enlarging the capacity of the pressure chamber at a first stage and contracting it in a second stage into the state before enlargement, thereby emitting the recording liquid; and a device for adjusting the time interval between the first and second stages to adjust the emitting velocity. The capacity of the pressure chamber is changed due to charge and discharge by a charging/discharging circuit, and charge/discharge time constants of this circuit are selectively controlled by a control unit. According to this driver, mixture of air into recording liquid in the ink-jet head when the piezo-electric element is expanded is prevented, and a variable range of a dot diameter of the recording liquid droplet can be extended, thereby improving recording quality.

摘要： For reproducing a picture with a density gradient through printing, an overlapped region is provided in a high density dot reproduction range and a low density dot reproduction range. The switch-over between the high density dot at the overlapped region is conducted where the picture density sharply changes. This reduces the unfavorable perception of quality differences in a printed picture resulting from the switch-over between the high and low density dots.

摘要： An image forming method comprises the steps of providing pattern elementary marks which provide an image pattern, controlling the size of the pattern elementary marks, and forming the pattern elementary marks substantially at equal intervals. The controlling step is such that use is made preferentially of the pattern elementary marks in an area wherein the variation in density gradient level relative to the variation in size of the pattern elementary marks is great. An apparatus for carrying out such method is provided.

摘要： A picture producing apparatus forms a picture comprising a plurality of picture elements with different light-reflecting properties providing different optical reflection densities using a plurality of dot forming units to provide dots of recording materials of different concentrations. The optical reflection density range of an entire original picture to be reproduced is determined and selecting circuitry responsive to that determination selects at least one of the dot forming units to form picture elements reproducing the original picture. The dot forming units vary the areas of the picture elements formed by the dots so as to represent in the reproduced picture the optical reflection density range of the original.
