摘要： When recording a color image on a recording medium according to record data using black ink and color ink of a plurality of colors having a different characteristic of permeation into the recording medium from the black ink, detecting the boundary between a black image and a color image is executed. For an area where the boundary has not been detected, normal printing which can record the image at a relatively high speed is set. For an area where the boundary has been detected, multi-pass printing which can record the image at a relatively low speed is set. Thus, a drop of recording speed and bleeding at the boundary are prevented.

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： 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.

摘要： A column band pattern memory (10) stores six different column band patterns "SML, SLM, MSL, MLS, LSM, and LMS" obtained by re-arranging three different area modulation ranks (L, M, and S). A column band pattern generator (12) irregularly selects one of the column band patterns stored in the column band pattern memory (10) on the basis of a numerical value generated by a random number generator (11). The selected column band pattern is input to a dot area determination unit (13), and dot areas in units of columns are determined on the basis of the order of dot area modulation ranks (e.g., the order of S, M, and L) in the selected column band pattern. A pulse controller (14) performs pulse control to form dots in accordance with the dot areas determined by the dot area determination unit (13).
