    摘要： In the case of printing in three-value level utilizing two kinds of inks mutually different densities for one color (higher and lower density inks), it is assumed that a reflection density of a region having a predetermined area when solid print is performed only by the lower density ink, and that when solid print is performed only by the higher density ink are expressed ODt and ODn, respectively. Since the granular appearance of the ink dots is expressed in terms of reflection density of one dot, the granular appearance of a lower density ink dot at a portion of image formed only by the lower density ink dots and the granular appearance of a higher density ink dot at a portion of image formed by the higher and lower density ink dots are expressed in terms of values of ODt and (ODn-ODt) divided by the number of pixels included in the above region, respectively. Accordingly, by making the reflection density ODt to be approximately one half of the reflection density ODn, the granular appearance produced by the lower density ink dot at the highlighted portion and the granular appearance produced by the higher density ink dot at the portion where the higher density ink dots scattered in the lower density ink dots can be made substantially equal to each other. For this purpose, it is preferable that a dye concentration of the lower density ink is to be about one fourth of that of the higher density ink.

    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： Print codes supplied from a host computer are received and analyzed to generate print data for the individual colors, and the generated print data are stored in print buffers corresponding to the colors. The print data corresponding to yellow ink with high lightness is expressed by binary data, and is printed by one dot per pixel by a single print scan. The print data corresponding to each of the remaining high-density (thick) inks is expressed by multi-valued data having a larger number of bits than the yellow data, and is printed by a plurality of print scans.
