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.

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.

摘要： An image is recorded on a recording medium by recording dots of a black ink and a color ink discharged onto the recording medium from a recording head. A boundary proximity-degree detecting circuit detects the degree of positional proximity, i.e., closeness, between the recording dots of the black ink and the recording dots of the color ink at the boundary between these dots. A dot substituting circuit performs, in accordance with the detected degree of positional proximity, substitution of the black pixels with recording dots of a color ink at the boundary. Thus, pixels of the image to be recorded are replaced with recording dots of a color ink by an extent which is determined based on the degree of positional proximity between the pixels of the different colors. A sharp black image can be obtained with minimized color mixing at the boundary between the black image region and the color region, regardless of the degree of positional proximity between these regions.

摘要： In a multi-scan method for printing a printing area by n (4) scans of a head and printing individual scan lines with n different ejection ports, a paper feed amount of transporting performed between the individual n scans is set to a value less than an amount of {(a length of total ejection port)/(n-1)}, and thereby close ejection ports in the ejection port arrangement in the head can be used as the n ejection ports for the individual lines, and an application position deviation between the ejection ports for individual lines due to a head mount error or the like can be reduced. As a result, unevenness of density due to deviation of dots in a scanning direction can be suppressed.

摘要： When it is determined that a temperature of a recording head exceeds a predetermined temperature, a head exchange inhibit mode shift flag is set. Thus, even if an input to command the exchange of the recording head which is at a high temperature is made, the exchange operation is inhibited or the exchange is disabled.
