摘要： An ink jet printing method is provided which, although it uses an ink jet print head with a fixed small ink ejection volume, can form an image with a desired density by performing data processing and printing at a lower pixel density. The dot arrangement pattern that determines the presence or absence of a printed dot in each of a plurality of element areas making up each pixel is allocated to the individual pixels according to their grayscale level. Then the printing dots are divided into a plurality of scans of the print head. At this time, for those pixels having a predetermined grayscale level, a plurality of dots are printed overlappingly in each of predetermined element areas of these pixels. This arrangement allows a greater number of dots than is determined by the allocated dot arrangement pattern to be printed in these pixels according to the grayscale level.

摘要： An ink jet recording apparatus is structured to perform discharges in the capping status when preliminary discharges are performed in a shot number larger than a predetermined number, and perform discharges in a cap or a preparatory port other than the cap when the preliminary discharges are performed in a shot number less than the predetermined number. With the structure thus arranged, it is made possible to implement the suppression of the mist generation due to the preliminary discharges, and to make the time of recording on a recording medium shorter as well.

摘要： The ink jet printing apparatus forms an image on a print medium with the following two operations. The printing operation makes a print head perform scan motions in a predetermined direction on the print medium, the print head having an array of nozzle rows corresponding to the required number of ink colors, each scan motion involving the ink being ejected from nozzles onto the print medium. The print medium feeding operation moves the print medium and the print head relative to each other a predetermined amount in a direction different from a direction of the scan motion between the scan motions. In a print mode using a small number of ink colors employed for printing, unidirectional printing is performed such that the nozzle row of a black ink to be ejected reaches a print start position when amplitude of vibration of the print head is a predetermined amount or less.

摘要： The present invention allows for creating high quality images by coping with a variety of kinds of print mediums without having to prepare large-sized, large-capacity power supply and ink supply source. For this purpose, this invention detects the number of printing elements to be driven in a predetermined check area set in one scan area of the print head. If the detected value is greater than a predetermined threshold, either the number of printing elements to be driven in one scan period of the print head or one scan period from when the print head starts the printing scan until the next printing scan is started is selected and changed according to the set printing condition and the printing operation is performed accordingly.

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.

摘要： An ink ejection nozzle constituting section for performing printing with a high image quality and an ink ejection nozzle constituting section for performing full-color printing at a high speed are separately disposed in one ink jet head. A recovery system is capable of performing suction recovery only in each of the nozzle constituting sections, and the suction recovery optimized for each constituting section is carried out. Accordingly, an increase in size of a recording apparatus can be restrained, and total ink consumption can be suppressed at the time of maintenance.

摘要： The invention prevents a pattern arising from periodicity of dot arrangements from appearing as noise, such as a streak, when a plurality of different dot arrangements are used repeatedly in a unit of a predetermined number of the dot arrangements for the same level of gradation of input image data, and thereby makes it possible to print a high-quality image. To this end, when input image data quantized to one of multivalued levels of gradation is allocated to a dot arrangement of M×N, a matrix of A×B created by combining a plurality of different dot arrangements each displaying the same level of gradation of the input image data in a raster direction and in a column direction is used as a minimum unit, and the dot arrangement of this matrix is allocated to the input image data.
