    摘要: A plurality of patterns respectively having different area factor of dot formation area are formed by forward and reverse scanning printing of a print head, and then optical characteristics of the plurality of formed patterns are measured. A function representing the relationship between the printing position offset between the forward and reverse printings is determined from the optical characteristics. Then, respective pattern having a predetermined area factor of dot formation area is formed by means of forward and reverse scanning where the speed is differentiated according to the mode of a printing apparatus, and then the optical characteristics of this pattern is measured. By applying this measured optical characteristics to the function, an adjustment value of the dot formation position conditions between the forward and reverse scans is obtained for each mode. This makes it easy to perform printing registration in a printing apparatus in the case of printing by a forward and reverse scan of a printing head or in the case of printing by means of a plurality of printing heads. In this case, operations by a user etc. are also unnecessary and are easily performed.

    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.

    摘要: In an ink jet printing apparatus using many types of inks to execute bidirectional printing, if ejection opening rows for yellow, magenta, and cyan inks are symmetrically arranged, ejection opening rows for a black ink are arranged adjacent to the most inside ejection opening rows for the yellow ink. Thus, a difference in color between forward scanning and backward scanning is determined by a difference in coloring between the black ink and the yellow ink. In this case, a possible color drift attributed to bidirectional printing can be suppressed by selecting the inks so that the difference in coloring between the black ink and the yellow ink is smaller than that between the black ink and the other color inks.

    摘要: A construction of a printing apparatus wherein a printing registration with respect to forward and reverse scans of a printing head and a printing registration with respect to a plurality of printing heads are automatically carried out is realized without rendering the apparatus complex or causing its production cost to rise. To this end, the optical sensor for measuring patterns formed for use in printing registration is also used to serve other purposes such as a detection of a printing home position or a detection of a printing medium's end. Furthermore, by appropriately controlling a single optical sensor according to each of various intended purposes, the optimum characteristics are utilized in each respective operating mode. Because of the above, the addition of sensors to be used only for the purpose of printing registration and the accompanying rise of the print apparatus production cost are restrained.

    摘要: An ink jet recording apparatus records by supplying heat energy according to a drive pulse to an ink to form a bubble based on film boiling and ejecting the ink from a recording head onto a recording medium based on formation of the bubble. The ink jet recording apparatus includes a driver for supplying a pre-driving pulse that does not cause ink ejection and a main driving pulse that causes the ink ejection with a rest period between the two pulses for ejection of one ink droplet, and a rest period controller for controlling the rest period within a range where an amount of the ink ejection increases in accordance with an increase of the rest period. Controlling the rest period controls an amount of the ink ejection, with the rest period based on a temperature of the recording head. Also, a temperature of the recording head is obtained by calculating the energy input to the recording head by the supplied driving pulses.
