摘要： Disclosed are an ink-jet printing method and apparatus for jetting ink successively from nozzles of an ink-jet head at a prescribed frequency and forming each of a number of pixels by a plurality of dots conforming to the tone of the pixel. Each nozzle of the ink-jet head has a heater A and a heater B. Printing is performed by changing the number of heaters actuated to jet an ink drop, thereby to control the formation of a large or small dot by each nozzle, and by changing the method of driving the heaters A and B in dependence upon the density of the ink used. In regard to the timings at which the large and small dots are formed by each nozzle, the small dot is formed first. As a result, the large and small dots can be made to overlap so that an image having excellent tone reproducibility can be printed.

摘要： Small dots and large dots are recorded with a sufficient difference between them by such structure that a plurality of heat generating elements are disposed inside of each nozzle. A single pulse is applied to one heat generating element for recording of a small dot, whereas a single pulse and a divided pulse are applied to two heat generating elements for recording of a large dot. When the divided pulse is applied to the heat generating element, a larger amount of the ink is ejected than upon application of the single pulse. Therefore, the sufficient difference can be generated between the sizes of dots by applying the driving pulses as described above.

摘要： For a temperature adjustment process that uses high viscosity ink and is based on a first table, in a low temperature environment, an ink refill failure may occur and lower density may appear in high duty printing. Also for a temperature adjustment process that uses high viscosity ink and is based on second and third tables, in a low temperature environment, an ink refill failure may occur and lower density may appear. On the other hand, for a temperature adjustment process that employs a fourth table, a smaller pre-heat pulse width than that for the first table, for the conventional temperature adjustment, is employed in the same low temperature environment. Therefore, an ink refill failure does not occur, and horizontal or vertical gaps do not appear during high duty printing.
