摘要： Recording in a recording apparatus is controlled according to the temperature of a recording head. The temperature of the recording head and the surrounding temperature around the recording head are detected. An offset value, based on the temperature of the recording head and the surrounding temperature, is set at a predetermined timing. The detected temperature of the recording head is corrected, based on the offset value. The offset value is renewed, based on the head temperature and the surrounding temperature, during repetition of detection of the head temperature.

摘要： An ink is ejected at the same timing from ejection orifices in a number corresponding to an ink quantity 7% or less of an ink quantity ejected from all the ejection enabled ejection orifices of a plurality of ejection orifices of a recording head, and the ink ejection period from all the ejection enabled ejection orifices is set to be 70% or more of the driving period. Since the quantity of an ink ejected per unit time is minimized, and the negative pressure level generated in a common ink chamber can be set to be closest to normal pressure, the amplitude of a refill oscillation is minimized to stabilize ejection, and the driving frequency can be further increased.

摘要： An ink-jet recording apparatus ejects ink droplets having two sizes, a large size and a small size. The ink-jet recording apparatus records data with a pattern assigned to quantized data. This arrangement reduces density non-uniformity and streaks related to the landing accuracy of ink droplets, the accuracy of sheet conveyance in the recording apparatus, and the accuracy of carriage scanning. Recording is performed with large and small dot-matrix patterns assigned to quantized data on independent planes. When the large dot and the small dot in a pattern are provided to one pixel at the same time, the large dot and the small dot are placed in positions not overlapping in the one pixel.

摘要： An image processor in which an under color process is performed according to a color region to which input color image data belongs. The under color process generates a plurality of color component signals including a black component signal including a black component signal, with the color region being defined by hue. Therefore, even if input color image data includes color components other than an under color component, tonality (i.e., linearity between an input color value and an output color value) is compensated for.

摘要： In an ink-jet apparatus for forming images through use of an ink-jet head provided with a plurality of ink ejection heaters with respect to only one ejection orifice, an accurate estimation of temperature of the ink-jet head is made possible by controlling ink-ejection amount in a step-by-step manner. For this purpose, there is provided a device for counting frequency of use of the plurality of heaters within a predetermined period of time independently for each combination of the heaters for ejecting different amount of ink (in steps S1002, S1003), and a combining device for adding a correction value to each of the thus counted value on the basis of the heater driving condition, and converting the total value into the energy applied within a predetermined period (in steps S1008, S1004 and S1005). The estimation of temperature is performed by use of the thus obtained energy.
