摘要： This invention relates to an ink-jet printer equipped with an ink-jet printhead and a control method and apparatus for the ink-jet printer. The printhead incorporates an EEPROM storing head information including the ink discharge amount characteristics of the printhead. The head information stored in this EEPROM is transmitted from the ink-jet printer having the printhead to the printer driver of a host computer. The printer driver then selects a gamma correction table in accordance with the head information. In this case, a gamma correction table is selected from a plurality of gamma correction tables in which pieces of correction information which make print densities uniform are stored in correspondence with ink discharge amounts. This table also includes correction data for correcting an increase in ink discharge amount to prevent beading due to an increase in ink discharge amount with a rise in the temperature of the printhead.

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.
