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： 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.
