摘要： In an inkjet printer that prints an image by a forward scan and a backward scan of printing heads, it is determined whether or not a color unevenness occurrence value set on the basis of values of unit image data constituting image data is more than a predetermined threshold value. If the color unevenness occurrence value is less than the threshold value, data that enable a dot to be formed in a unit area corresponding to the unit image data by the forward scan and the backward scan of the printing heads are generated. If the color unevenness occurrence value is more than the threshold value, data that enable a dot to be formed in the unit area only by one of the forward scan and the backward scan of the printing heads are generated.

In the present invention, it is determined whether or not a color unevenness occurrence value set on the basis of values of unit image data constituting image data is more than a predetermined threshold value. If the color unevenness occurrence value is less than the threshold value, data that enable a dot to be formed in a unit area corresponding to the unit image data by the forward scan and the backward scan of the printing heads are generated. If the color unevenness occurrence value is more than the threshold value, data that enable a dot to be formed in the unit area only by any one of the forward scan and the backward scan by the printing heads are generated.

摘要： To provide an apparatus and a method that are capable of recording by performing the number of recording scans appropriate for the level of color non-uniformity.When recording is performed by causing a recording head to scan a unit region of a recording medium multiple times, values related to the respective amounts of inks of multiple colors to be ejected to each of sub-regions obtained by dividing the unit region in the scanning direction are obtained. On the basis of values related to the respective amounts of the inks of multiple colors for a sub-region of interest and neighboring sub-regions adjacent to the sub-region of interest, the number of scans for the unit region including the sub-region of interest is determined.

摘要： An ink jet printing apparatus is provided which can form sharp images while maintaining high grayscale levels even if the images include various kinds of image constitutional elements to be printed by image data having different attributes, such as character, fine line and image data. This invention checks attributes of the input image data corresponding to the image constitutional elements making up the images and also detects edge and non-edge portions of the image constitutional elements. Further, this invention generates print data for printing the edge portions and print data for printing the non-edge portions based on attributes of the input image data corresponding to the image constitutional elements.

摘要： An object of the present invention is to provide an ink jet printing apparatus and an ink jet printing method which can inhibit degradation of image quality resulting from ink drying unevenness regardless of the type of ink and the amount of ejected ink. To accomplish the object, the present invention determines, based on print data, drying characteristics of ink applied by a print head to a predetermined time control area in an image forming area to be formed on a print medium. Based on the result of the determination, a wait time is controlled which is set between a preceding scan and a succeeding scan in a plurality of scans performed within the wait time control area.

摘要： Multiple alignment patterns, each composed of first and second alignment pattern elements printed by forward and backward movements of a print head, respectively, are formed while the relative printing positions of the two elements are shifted. From optical characteristics data thereof, whether the data is influenced by a disturbance is determined. When the data is determined to be less influenced by the disturbance and therefore to be reliable, an adjusting value for aligning positions in printing in reciprocal movements is calculated by use of: data with the smallest relative printing position misalignment between the first and second alignment pattern elements; and data of optical characteristics close to the data. When the data is largely influence by the disturbance, a range of shifting of relative position is widened than that of the data less influenced by the disturbance so that more data pieces are used to obtain the adjusting value.
