    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 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： An ink-jet printing method, an ink-jet printing apparatus and an ink-jet printing system, which are free from the deterioration of color development effect even if a plurality of color inks are used, caused by the overlap of different color inks on a printing medium, are proposed. For this purpose, when density data quantized to several ranks are converted finally to binary data by using predetermined dot arrangement patterns, a dot arrangement pattern different from those for other color inks is prepared for a particular color ink. Accordingly, it is possible to reduce as much as possible the probability that the particular color ink is overlapped with the other inks on the printing medium, whereby the color development of the particular color ink is effectively facilitated.

    摘要： An object of the present invention is to control the amount of deposit in an ink receiving portion using an inexpensive configuration which does not require any complicated mechanisms or control and which avoids increasing ink consumption. The present invention thus has ejection control section for ejecting ink from printing section into an ink receiving portion provided opposite a print head. 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 portion depending on the status of accumulation of the ink in the ink receiving portion.

    摘要： A recording apparatus is configured to record an image on a recording medium by repeating a recording operation and a conveying operation. The recording operation is operative to apply a recording agent to the recording medium using a recording head while moving the recording head for scanning in a direction different from a predetermined direction. The recording head includes a plurality of recording elements arranged in the predetermined direction and adapted to apply the recording agent. The conveying operation is operative to convey the recording medium in a direction transverse to the scanning direction. The recording apparatus includes a recording control unit configured to perform the recording operation such that a number of the recording elements which are used to record an image on at least one of a front end portion and a rear end portion of the recording medium is reduced at a rate as compared to that of the recording elements which are used to record an image on a central portion of the recording medium, and a recording mode selecting unit configured to select a recording mode from a plurality of recording modes differing from one another in at least one of recording quality and recording time. The recording control unit changes the rate of reduction according to the recording mode selected by the recording mode selecting unit.
