摘要： According to the present invention, if an image is printed on both sides of a printing medium, the possibility of rubbing ink off from the printing medium is minimized to inhibit contamination of the printing medium and the interior of the printing apparatus, while maintaining the print grade of the image. Thus, if a double side print mode is executed in which an image is printed on both sides of the printing medium, then, for a particular image part, a ratio of an amount of black pigment ink used to an amount of black dye ink used is set so as to limit the amount of black pigment ink used and to compensate for a decrease in print density with the limited amount of the black pigment ink used.

摘要： To enable the printing in which it is difficult for the dot to stand out and it is difficult for the gradation sequence properties to be degraded. Therefore, among plural dots each having a different size, the binary processing is carried out by using the same first dot arrangement pattern in regard to the large and medium-sized dots and the binary processing is carried out by using a dot arrangement pattern different from the first dot arrangement pattern in regard to the small-sized dots.

摘要： On performing a predetermined printing operation, whether or not, among a plurality of printing elements, only a part of the printing elements are applied is detected. If it is judged that only the part of the printing elements are used, a judgment is made whether or not the preliminary discharge operation is performed based on the number of discharges for the part of the printing elements, and if it is not judged that only the part of the printing elements are used, a judgment is made whether or not the preliminary discharge operation is performed based on the number of discharges for all of the printing elements of the printing head. This eliminates an unnecessary preliminary discharge for non-printing elements even in a printing operation mode in which only a part of the printing elements are applied.

摘要： An ink jet print apparatus having a plurality of double-sided printing modes (e.g., automatic double-sided printing mode and manual double-sided printing mode) produces a sufficient image quality whichever mode is executed. For this purpose, image data to be printed is converted into print image data usable by the printing apparatus in a way that matches a selected one of multiple print medium transport paths. This minimizes a curling problem due to variations in transport processes, image quality variations caused by an ink fixing problem and adverse effects on the printing apparatus and ensures a stable printing whichever transport path is used for printing.

摘要： The objective of the present invention is to provide an inkjet printing apparatus that can efficiently feed printing media stored in a media storage unit, while at the same time minimizing the reduction in a printing speed during the ejection recovery operation, and an inkjet printing method therefor. Thus, according to the present invention, the ejection recovery operation is performed during a period extending from the end of printing for a preceding printing medium which is fed first by a feeding unit, to start of printing for a succeeding printing medium. The recovery operation is controlled at this time in accordance with a feeding condition under which the feeding operation performed by the feeding unit is determined.
