Title:
インクジェット記録装置及び前記装置の制御方法
Document Type and Number:
Japanese Patent JP3559753
Kind Code:
B2
Abstract:
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 (1008) 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 (3010) 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 blurring due to an increase in ink discharge amount with a rise in the temperature of the printhead.
