摘要： In an liquid ejection head according to the present invention having a plurality of ejection openings arranged in a predetermined direction and a plurality of electro-thermal transducers for ejecting liquid from the ejection openings and being in relative motion with a printing medium, a kinetic energy of the liquid ejected from each ejection opening constituting an end group disposed in the respective opposite end section along the predetermined direction is larger than a kinetic energy of the liquid ejected from each ejection opening constituting a central group disposed in a central section along the predetermined direction. According to the present invention, it is possible to prevent an ink droplet ejected from the ejection opening in the end group from being deviated toward the central section along the predetermined direction, whereby the generation of white streaks is avoidable when a solid printing is carried out.

摘要： With an ink jet head having for each color two parallel columns of nozzles arranged shifted by one-half the pitch, odd-numbered rasters and even-numbered rasters are printed by the two nozzle columns. The registration between the odd- and even-numbered rasters is secured during the printing to produce a high quality image. The ink ejection timing between the two raster groups is shifted by a predetermined interval to form adjustment patterns; the adjustment patterns are checked and, according to the check result, an adjustment value for the ink ejection timing between the two ink nozzle columns is entered, and the entered adjustment value is stored to be reflected on the actual printing operation. To facilitate the adjustment pattern check, the adjustment patterns have a dot distribution with a blue noise characteristic at a resolution at which the printing apparatus can print.

摘要： In an ink-jet printing apparatus which includes a plurality of printing heads, each having an array of ink discharging elements, preliminary discharge of driving the elements of at least one printing head is performed a predetermined number of times. The printing head for which the preliminary discharge is to be performed is switched in a predetermined cycle. In performing the preliminary discharge, switching of the printing head is so controlled as to perform preliminary discharge a desired number of times for all the elements of the printing heads by repeating the cycle.

摘要： An ink-jet printing apparatus, for printing an image based on image information on a printing medium by relatively moving an ink-jet printhead, detects the temperature of the ink-jet printhead by using a head temperature detection unit and outputs it to a driving frequency determination unit. The driving frequency determination unit acquires temperature information in units of pages of image information or predetermined image areas. If the acquired temperature is equal to or higher than a predetermined temperature, the driving frequency of the ink-jet printhead is decreased when a predetermined unit of the image information is printed.
