    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.

    摘要： An ink jet recording apparatus, in which thermal energy is applied to ink in accordance with a driving signal applied to a heater to produce a bubble, by which ink is ejected onto a recording material, includes a driver for applying a plurality of driving signals to the heater for one ejection of one ink droplet. The driving signals comprise a first driving signal not ejecting the ink and a second driving signal for ejecting the ink, the second driving signal being applied after a rest period after the first driving signal. The apparatus further includes a controller for changing an amount of ink ejected by changing a length of the rest period and changing the first driving signal. The controller effects its changing operation in a first changing region in which the rest period is changed without changing the first driving signal and in a second changing region in which a length of the first drive signal is changed.
