摘要： A recording method ejects ink by thermal energy produced by a heat generating element of a recording head in response to a drive signal. The method includes the step of controlling an amount of ejection of the ink by a temperature control for the recording head including at least heating of the recording head, when a temperature of the recording head is not higher than a predetermined first temperature. The method further includes the steps of controlling the amount of ejection of the ink by changing a waveform of the drive signal for ejecting ink in accordance with the temperature of the recording head when the temperature of the recording head is higher than the first temperature and not higher than a second temperature, and fixing the waveform of the drive signal when the temperature of the recording head is higher than the second temperature.

摘要： A plurality of recording heads for ejecting inks of different colors are reciprocally moved relative to a recording medium, and printing operations are performed by executing main scans in forward and backward scans of the recording heads. In this case, an area printable in a single main scan is recorded by performing a plurality of main scans using a plurality of thinning patterns in which an m.times.n pixel group is defined as a unit pixel group, and the pixel groups are arranged at non-neighboring positions, and which have a complementary arrangement relationship therebetween. A high-quality color image free from time difference nonuniformity, and density nonuniformity caused by, e.g., variations of recording elements is obtained at high speed.

摘要： There are provided ink jet printing method and apparatus which assure that reciprocable printing can be realized at a high speed without any deterioration of a quality of printing. When an image is printed on a printing medium by using a multi-orifice head of which the ink ejecting direction relative to an opening surface is inclined in the return scanning direction, a scanning speed of the return scanning direction is delayed from the scanning speed in the reverse forward direction, an offset distance between a main dot and a satellite at the time of the return scanning is suppressed to be small, and in the case that printing is performed by reciprocable scanning, the satellite is received in the main dot not only during the forward scanning but also during the return scanning.
