Abstract: In an ink-jet apparatus employing an ink-jet head having a plurality of heaters corresponding to one ink ejection opening, appropriate preliminary ejection is performed per each ejection amount mode set by heater to be used among a plurality of heaters. Depending upon set printing mode (step S9), printing is the performed one of large, medium and small ejection amount modes (steps S10, S12, S14). For example, after printing is performed for a predetermined amount by the small ejection amount mode (step S10), the preliminary ejection during printing, is performed in the medium ejection amount mode which is greater in ejection amount than the small ejection amount mode. By this, internal of preliminary ejection during printing can be set longer to prevent lowering of through put due to preliminary printing operation.

Abstract: The invention aims to solve problems occuring when images of different resolutions are recorded together. Interference occurs in the images, gaps are created between the images or excessively high density areas appear due to a difference in resolutions, that is, changes of dot sizes and recording densities in the recording in areas where low and high resolution images are recorded together or such images are adjacently present. In a recording area where low and high resolutions images are to be recorded together, the recording positions of the low resolution images are offset with respect to the high resolution images. Also, in the boundary portion where low and high resolution images are adjacent to each other, supplementary dots are recorded or dots are recorded intermittently in accordance with the present invention.

Abstract: A liquid ejection method includes preparing a head comprising an ejection outlet for ejecting the liquid, a bubble generation region for generating the bubble in the liquid, a movable member disposed faced to the bubble generation region and displaceable between a first position and a second position further from the bubble generation region than the first position; displacing the movable member from the first position to the second position by pressure produced by the generation of the bubble in the bubble generating portion to permit expansion of the bubble more in a downstream side closer to the ejection outlet than in an upstream side; supplying, to a heat generating element for applying thermal energy to the bubble generating region, a driving pulse divided into a first pulse and an adjacent second pulse with interval time therebetween; pre-heating the liquid by the first pulse to an extent not enough to eject the liquid through the ejection outlet; generating a bubble by heating the liquid by the second pulse to eject the liquid through the ejection outlet; controlling a degree of pre-heating of the liquid by changing at least one of a pulse width of the first pulse or the interval time.
