摘要： Mask patterns to be used for multi-pass printing make it possible to make a print with a higher quality at a higher speed. Specifically, by performing a swapping process with adjacency forbiddance, two points in the horizontal direction, or the scanning direction of a printing head, are selected in a buffer in which codes for each scan pass are set depending on printing ratios of a gradation mask. Subsequently, codes are swapped between the two points. By this swap, adjacencies between print permitting areas are eliminated in the mask pattern. As a result, when driving frequencies set for the printing head is kept constant, the scanning speed can be doubled at minimum.

摘要： A content of (an amount of ink to be suctioned for, or the number of times ink is preliminarily ejected for) the maintenance process to be performed after the ink tank replacement is made different depending on the amount of ink so far consumed from a tank which is replaced. This makes it possible to check the color mixture which would otherwise occur after the new ink tank is attached to the printing apparatus, and to concurrently manage an amount of waste ink in order that ink should not be consumed more than necessary in a case where the color mixture is less likely to occur.

摘要： High image quality is maintained even on front and rear ends of a printing medium where deterioration in the image quality is more likely to occur due to reduction in conveyance accuracy of the printing medium. In printing on the front and rear ends, the printing medium being not supported by both conveying means respectively placed upstream and downstream of a printing point in a printing medium conveying direction, a print swath of a printing head and the amount of conveying a printing medium are reduced. Moreover, the reducing print swath and the reducing conveyance amount are designed to be decreased in the cases of selecting a printing medium for high-quality printing as well as a monochrome print mode where image distortion caused by deviation of ink-landing positions is more noticeable due to a small number of colors of ink to be used and low coverage thereof.

摘要： An object of the present invention is to appropriately dispense treatment fluid to wipers, and to always wipe ejection-orifice formation surfaces in a favorable state regardless of an environmental change and the like. To this end, in the present invention, a treatment-fluid holding portion holds treatment fluid used in a wiping operation of wipers. When the wipers contact the treatment-fluid holding portion, the treatment fluid is transferred to the wipers. In an environment where the treatment fluid is thickened, the wipers with ink dispensed thereto are brought into contact with the treatment-fluid holding portion to supply ink to the treatment-fluid holding portion. Thus, the viscosity of the treatment fluid near a contact portion between the treatment-fluid holding portion and the wipers decreases, and the treatment fluid is sufficiently transferred to the wipers.

摘要： Image deterioration due to decrease in transfer amount, which arises when a remaining amount of wetting liquid for wet wiping is decreased, is reduced in an ink-jet printing apparatus. When the remaining amount of the wetting liquid decreases to reach a predetermined amount or less, a wetting liquid tank is moved down, and thereby an intrusion amount of a wiper into a transfer portion is made larger than a standard value. This increases an area of the wiper where the wiper comes into contact with the transfer portion, which allows the transfer amount to be maintained at a substantially same level as the reference value. This enables the transfer amount to be prevented from decreasing when the remaining amount decreases, and the transfer amount almost the same as that in an initial stage to be ensured even in a later stage of an apparatus life time.

摘要： An amount of deposit in an ink receiving portion can be controlled using an inexpensive configuration which does not require any complicated mechanisms or control and which avoids increasing ink consumption. An ejection control section controls ejecting of ink from a printing section into an ink receiving portion. The printing section has a first ink ejecting portion that ejects ink that accumulates easily in the ink receiving portion and a second ink ejecting portion that ejects ink that is hard to accumulate in the ink receiving portion. The ejection control section changes the landing position, in the ink receiving portion, of the ink ejected from the ink ejecting portions depending on the status of accumulation of the ink in the ink receiving portion.
