摘要： A voltage pulse that keeps the ejection volume within a specified range is selected for a plurality of print element columns, based on the heater rank and ink temperature information that influences the ejection volume during ink ejection. At this time, the voltage pulse is controlled so that the voltage value of the pulse is equal for a plurality of print element columns at any ink temperature and varies according to the ink temperature. This control process enables pulses of the same voltage value to be applied at all times to a plurality of nozzle columns even if these nozzle columns in the print head have different heater ranks. As a result, the ejection volumes of all nozzle columns can be kept within a specified range with high precision over a wide range of base temperature, without requiring complicated circuit configurations.

摘要： The present invention is intended to make it possible to form patches that allow for a high precision measurement of a threshold of an electric energy to be supplied to nozzles of a print head, without using a high-precision sensor. To this end, this invention changes the electric energy supplied to the nozzles of the print head stepwise in printing patches that are used to measure an ink droplet ejection state of the nozzles for each level of electric energy. The patch printing involves dividing the nozzle column of the print head into a plurality of nozzle groups and scanning at least one of the nozzle groups a plurality of times over each of the plurality of patch forming areas set on a print medium.

摘要： An ink-jet printing apparatus and an ink-jet printing method allow the printing of an image with high quality without causing a change in ink color formed on the printing medium while keeping the printing conditions constant regardless of changing of the number of nozzles to be printed and the amount of transferring of the printing medium. This printing is performed, for example, by restricting use of the number of nozzles, which belong to a nozzle row located on an upstream side in the sub-scan direction, before changing the amount of transferring of the printing medium; and restricting use of the number of nozzles, which belong to the nozzle rows located on a downstream side in the sub-scan direction, after changing the amount of transferring of the printing medium.

摘要： In a printer, when difference in ejection characteristic among nozzles appears as density non-uniformity and the way of letting the density non-uniformity appear is different depending upon kind of image, proper density correction is performed. Specifically, the kind of image to be printed is judged, and when the kind of image is a halftone image according to the judgment, a density correction table corresponding to the halftone image is selected and used to perform the density correction. Also when the kind of image is judged to be a solid image (without a portion of the halftone image), a proper table is selected similarly and used to perform the density correction.

摘要： In an image processing method, on the basis of input image data with respect to a target pixel, independent multi-level data (g0, g1) corresponding to respective plural species of dots which are different in at least one of a density and a diameter are generated, and then data (O0, O1) relating to an amount of generation of the dots with respect to the target pixel are generated on the basis of a relationship between the generated independent multi-level data (g0, g1) corresponding to the plural species of dots. The image processing method is effective in performing design having a high degree of flexibility in proper use of a relatively high power dot (high density dot or large dot) and a relatively low power dot (low density dot or small dot) and can realize obviation or alleviation of an occurrence of granulation or an apparent frame caused due to the relatively high power dot.
