摘要： There is provided an inkjet printing apparatus which executes a proper recovery operation in accordance with the demounting time period of an ink tank and information of the ink tank. In the inkjet printing apparatus of this invention, the demounting time period and information of the ink tank are used as parameters for determining the condition of a recovery operation after the ink tank is once demounted and thereafter mounted again. Since recovery is done in consideration of the degrees of ink evaporation and an increase in viscosity, wasteful ink consumption can be suppressed while a necessary recovery operation is performed.

摘要： A smooth, uniform image is produced by minimizing the occurrence of satellites of secondary color and dispersing landing positions of the satellites as uniformly as possible. For this purpose, the printing operation performed so that satellites of the two inks (cyan and magenta ink, foe example) ejected toward the same pixel are separated and landed on opposite sides of the main dots on the same pixel. This makes the distribution of satellites uniform and makes individual satellites less noticeable, maintaining the uniformity of an image.

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： 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： An ink jet printing apparatus is provided which is capable of producing an image with a good balance between image quality and printing speed, without unduly shortening a longevity of a print head, even when an odd-numbered-pass bidirectional printing is performed. To this end, during a bidirectional multi-pass printing with a relatively small number of passes, a stepping mask is used to eliminate image problems caused by a difference in print permitted ratio between forward scan and backward scan. During a bidirectional multi-pass printing with a relatively large number of passes, a flat mask is used to give priority to suppressing density unevenness resulting from nozzle characteristic variations. As a result, the printing apparatus as a whole can produce an image with a good balance between image quality and printing speed, without unduly shortening a longevity of the print head.

摘要： Even if an error occurred in a result of the detection by an optical detecting mechanism for optically detecting whether or not a remaining amount of ink in an ink tank is equal to or less than a predetermined amount, a correct situation of the remaining ink amount in the ink tank can be detected. A detecting method has a first discriminating step of discriminating whether or not a remaining ink amount in the ink tank is equal to or less than a predetermined amount by using an optical sensor and a second discriminating step of discriminating whether or not the remaining ink amount in the ink tank is equal to or less than the predetermined amount on the basis of information regarding an amount of ink consumed in the ink tank. If the absence of ink is determined in either the first or second discriminating step, information showing the absence of ink is notified.
