摘要： An ink jet printing apparatus that improves the visibility of a character and its background in different colors or of outline characters is provided. Specifically, outline character bold data is inverted and each of the pixels in the data is expanded to adjacent eight pixels. Then, the expanded outline character is processed into expanded inverted data. The logical AND of the inverted expanded data and K data on a background image is then calculated to generate K data with the outline character expanded. This results in an image with the outline character expanded. That is, the present invention enables characters with improved visibility and free from blurredness to be printed while preventing the adverse effect of bleeding on the outline character.

摘要： In a binarization process employing dot arrangement patterns, the deviation of formed dots is prevented from occurring. Specifically, the arrangements of the dot arrangement patterns of each of four planes, which correspond to the groups of the four species of dot arrangement patterns of one certain level of five-valued data, are determined. In a process for determining the arrangements of the dot arrangement patterns of the four planes, the repulsive potential between the dot arrangement patterns in each plane and the repulsive potentials among the dot arrangement pattern in one plane and the dot arrangement patterns in the other planes are computed. Besides, the arrangements of the dot arrangement patterns of the planes are determined on the basis of the results of the repulsive potential computations.

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.

摘要： In an inkjet printing apparatus which performs printing on a printing medium using an inkjet printhead for discharging ink, preliminary discharge, where ink discharge irrespective of printing is performed at the time of print execution, is performed under a predetermined condition. The printing apparatus includes a control section and a setting section. The control section executes a preliminary discharge by the printhead, which has a plurality of discharge orifices, before a predetermined time has elapsed since a latest preliminary discharge, in printing of an image, and the setting section sets the predetermined time. The setting section obtains an elapsed time after executing the preliminary discharge until a discharge failure occurs in any one of the plurality of discharge orifices, and sets the elapsed time as the predetermined time.

摘要： An object of the present invention is to provide a printing apparatus and a printing method even with a variation in the temperature of a print head, thus keeping the quality of images resulting from printing high. Adjustment patterns used to adjust the difference in ink ejection timing between ink ejected in a forward direction and ink ejected in a backward direction during scanning are printed at a plurality of different temperatures. Adjustment values for the ink ejection timing at the respective temperatures are selected from the adjustment patterns. Then, the correction value for the ink ejection timing is calculated from the adjustment values based on the temperature detected by the detection device. Printing is then performed with the difference in ink ejection timing between the ink ejected in the forward direction and the ink ejected in the backward direction during scanning, adjusted based on the correction value.

摘要： An ink jet printing apparatus which inhibits possible bleeding by thinning color data adjacent to black data and enables printing free from image quality degradation such as gradation skip is provided. Specifically, when only one pixel has color data and pixels located vertically and horizontally adjacent to that pixel have no color data, an isolated point pixel containing a color dot is detected only in that pixel. Then, the dots other than the isolated point are thinned-out. This makes it possible to inhibit possible bleeding at the boundary between a color area and a black area and to achieve proper printing with the appropriate gradation of the entire image maintained.
