摘要： Printing on an area of a printing medium in which printing locations may be significantly deviated due to inaccurate feeding of the printing medium can be performed, without degrading image quality. Specifically, when lines in this area (second area) are printed using four scanning operations (passes) of a print head, a duty in masking process is set at zero for the scanning operation (pass A) after a change-line operation for feeding the printing medium with a possible large shift feeding error, and is distributed to other scanning operations. Thus, no dots are formed during this scanning operation (pass A), thereby preventing significantly deviated dots from being formed.

摘要： The present invention relates to an ink jet printing apparatus which sufficiently heats a head even in a low-temperature environment, which enables a proper image to be printed by stably ejecting ink, and which can be inexpensively and simply constructed. According to the present invention, if the detected temperature of a printhead is lower than a first heating threshold temperature, a heating mode in which the printhead can be heated is set before a printing operation. Further, when the heating mode is set and the detected temperature of the printhead is lower than a second heating threshold temperature, a heating unit heats the printhead. Consequently, even in a low-temperature environment, the heating operation keeps ink in a desired condition suitable for printing.

摘要： The present invention provides a method of printing a high quality color image with no color variations at high speed. For this purpose, this invention arranges in a main scan direction a plurality of print heads that eject different color inks, and reciprocally moves each of the print heads to perform a multipass printing in which a print operation is executed in both the forward and backward passes. During the multipass printing, the print duties of the print heads are set by mask patterns. Each of the mask patterns divides the print duty setting area for each nozzle group of each head into subdivided areas, sets the print duties of the subdivided areas to values different from each other and sets the print duties of the print heads to different values.

摘要： In an ink-jet printing apparatus which includes a plurality of printing heads each having an array of ink discharging elements, preliminary discharge of driving the elements of at least one printing head is performed a predetermined number of times as a unit in performing preliminary discharge of discharging ink irrelevant to printing. The printing head for which the preliminary discharge is to be performed is switched in a predetermined cycle. In performing the preliminary discharge and switching of the printing head are so controlled as to perform preliminary discharge a desired number of times for all the elements of the printing heads by repeating the cycle.

摘要： The present invention reduces the granularity of the dots for the entire density range by optimally setting formation amounts of a low-density dot and of a high-density dot per unit area. For this purpose, the formation amounts of the low-density dot and of the high-density dot in accordance with the density level are determined in such a way that as the density level rises, the formation amount of the low-density dot is gradually increased up to a first peak amount (200%) and, after reaching the first peak, gradually decreased, and in a range of density levels higher than a predetermined density level at which the low-density dot is formed to a specified amount (200%), as the density level rises, the formation amount of the high-density dot is gradually increased up to a second peak amount (100%) smaller than the first peak amount.

摘要： An ink jet recording apparatus adjusts at least one of a preliminary discharge time representing a time until the subsequent preliminary discharge is performed and a compensated time determined on the basis of the time elapsed since the previous preliminary discharge, so that the preliminary discharge is performed at a predetermined preliminary discharge hole. Accordingly, the ink jet recording apparatus is capable of recording on different kinds of recording media in a manner suitable for each of them without using a complex control process, and of performing the preliminary discharge according to the size of the recording media. In addition, a reduction in the throughput is prevented by using the ink jet recording apparatus.
