    Abstract: In the print position adjustment procedure when performing bidirectional printing by using a first head and a second head, patterns (A) and (B) are printed to adjust the print positions of the first and second heads relative to each other in each of the forward and backward directions. A pattern (C) is printed to adjust the print position deviation of one of the two heads (first head) between the forward and backward directions. From these patterns three correction values are obtained to perform corrections. This allows the print position alignment between the forward and backward scans for one head (first head) to be performed by using the pattern (C). The print position alignment of the second head with respect to the first head as a reference in each of the forward and backward directions can be performed by using the patterns (A) and (B). As a result, print position deviations that may occur when the printing apparatus performs bidirectional printing using a plurality of heads can be minimized without having to maintain the precision of the apparatus at so high a level.

    Abstract: An ink jet printing method for performing printing onto a printing medium (106) with the use of both of a colored ink ejected from an ink jet head (702) and a printing property improving liquid to be applied to the printing medium (106) for improving a printing property for an ink jet printing apparatus, having the steps of: at least one time or more printing a first colored ink on the printing medium (106), at least one time or more applying the printing property improving liquid onto a region printed with the colored ink, and at least one time or more printing a second colored ink on a region where the printing property improving liquid is applied.

    Abstract: A liquid ejection method includes preparing a head comprising an ejection outlet for ejecting the liquid, a bubble generation region for generating the bubble in the liquid, a movable member disposed faced to the bubble generation region and displaceable between a first position and a second position further from the bubble generation region than the first position; displacing the movable member from the first position to the second position by pressure produced by the generation of the bubble in the bubble generating portion to permit expansion of the bubble more in a downstream side closer to the ejection outlet than in an upstream side; supplying, to a heat generating element for applying thermal energy to the bubble generating region, a driving pulse divided into a first pulse and an adjacent second pulse with interval time therebetween; pre-heating the liquid by the first pulse to an extent not enough to eject the liquid through the ejection outlet; generating a bubble by heating the liquid by the second pulse to eject the liquid through the ejection outlet; controlling a degree of pre-heating of the liquid by changing at least one of a pulse width of the first pulse or the interval time.
