摘要： A high-quality image is printed with reduced bleeding in colors that may appear at a boundary between a black image and a color image. A head for ejecting black ink and a head for ejecting color ink perform three times of scanning while feeding is carried out therebetween for moving the printing medium by four pitches of ejection openings arranged on the heads, different ejection openings are caused to correspond to a scanning area, which corresponds to the four pitches, and multi-pass printing is performed to complete printing on the area. The black head completes printing of the black image, and then, the color head completes printing of the color image adjacent to the black image. The arrangement of ejection openings is determined so that between last scanning for completing printing of the black image and the first scanning for printing of the color image, scanning with no performing printing exists.

摘要： Printing of a unit pixel (1/D=1/600) in 4-pass printing (64 nozzles, and a total sheet supply amount of 62/600 in four operations) is exemplified in an image printing apparatus capable of printing a uniform, high-quality image while avoiding printing of a visually nonuniform image in multipass printing of two or more passes. With an image printing apparatus as described herein, satellites can be uniformly printed on the right and left of a unit pixel.

摘要： An in-jet printing apparatus having a temperature detection device for outputting a signal in correspondence with a temperature, performs printing by using an ink-jet printhead which performs printing on a recording medium by discharging ink. A flag indicating whether acquisition of the temperature information is necessary or not is set, and the temperature information is obtained in accordance with the status of the flag, after the power on of the apparatus. The obtained temperature information is stored into a nonvolatile storage device. The temperature information can be obtained at appropriate timing in accordance with necessity, even if the power is interrupted during the operation. Thus a high-quality printed output can be obtained by performing a stable printing operation.

摘要： The present invention provides an ink jet recording apparatus capable of recording high-quality images in which not only color shading caused in the process of reciprocating recording is prevented, but also bleeding between colors inherent in a multi-pass recording method is reduced. The position of the top of ejection orifices in a second ejection orifice row for ejecting color ink is spaced a length away from a first ejection orifice row for ejecting black ink. The length is determined according to values m, n and such a condition that the value a makes (m+a) an even number. Under the circumstances, recording is performed by reciprocating scanning, which makes differences in recording time between colors equal to each other.

摘要： A recording apparatus is provided with two or more kinds of sub-scanning amounts per main scan, and records a high quality image by reducing the bleeding between colors created characteristically by a multi-pass recording method. The number of times of main scanning to complete an image by a first discharge port array for black ink use and a second discharge port array for color ink use, respectively, are set to be m (m is a positive integer) and n (n is a positive integer) times. With respect to discharge ports to be used for recording in the first and second discharge port arrays, a distance between discharge ports which are positioned at upstream ends of the respective first and second discharge port arrays in the sub-scan direction is made equal to a length of a continuously conveying amount of (m+a) (a is a positive integer) times by combination of the at least two kinds of conveying amounts.
