    摘要： Provided are a printing apparatus and a conveying-error controlling method capable of printing a high-quality image by correction reflecting the conveying amount of a printing medium. A provided inkjet printing apparatus prints images by printing scans for actual printing and by conveying the printing medium with a roller orthogonally to the printing-scan direction. In each printing scan, the printing medium is scanned with a print head having an array of nozzles from which the ink is ejected. The print head moving direction differs from the arranging direction of the nozzles in the array. The apparatus includes a conveying controller to control the conveying of the printing medium on the basis of a correction value used to correct a conveying error of the roller. The conveying controller changes the correction value to be applied in accordance with the conveying amount of the printing medium between two scans with the print head.

    摘要： The present invention aims to obtain preferable correction values to correct the conveying error of a conveying roller in accordance with the size of a printing medium, even when the conveying error caused by the eccentricity of the roller varies from a point to another in the longitudinal direction of a roller, depending on the amount and the state of eccentricity of the roller. To achieve this object, correction values are acquired using the whole part of or only a part of plural test patterns formed in the longitudinal direction of the roller. The correction values thus acquired correspond to the respective zones where the test patterns are formed.

    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 printing apparatus capable of forming a high quality multivalued image without using a plurality of print heads and suited for a size reduction is provided. In an ink jet printing apparatus in which the electrothermal transducers are heated by a drive pulse to generate bubbles in ink and in which the pressure of the bubbles is used to eject ink droplets from nozzles onto a print medium to print an image, the drive voltage and the drive pulse width for the print head are changed simultaneously in accordance with print data. For example, when ejecting small droplets, the drive voltage for the nozzles is increased and the drive pulse width shortened. When ejecting large droplets, the drive voltage is lowered and the drive pulse width elongated.
