摘要： In forming an image with plural recording heads corresponding to plural inks of different densities, the image data are so distributed that the image is formed with the ink of low density until the image density reaches a predetermined density level, but is formed with the inks of low and high densities when the image density exceeds the predetermined density level, and the distributed data are corrected according to the detection of temperature relating to the recording heads, whereby a desired recorded image can be obtained even in the presence of a variation in the head temperature. Also the image data are distributed in such a manner that, when the remaining amount of one of the plural inks becomes low, the recording is conducted with the remaining ink, whereby a desired image can be obtained even when the remaining amount of one of the plural inks with different densities becomes low.

摘要： An inkjet printing apparatus and a print head recovery method are provided according to which, in an environment in which dust (e.g., paper dust) is easily attached to the periphery of an ejection port of a print head, the print head is subjected to a recovery operation depending on the level of the attached dust. The inkjet printing apparatus has a cutter unit for cutting a print medium and a recovery unit for performing the recovery operation by wiping the ejection port formation portion at which the ejection port is formed of the print head while sucking the ejection port formation portion. When the passing number showing how many times the cut part of the print medium cut by the cutter passes the printing position is equal to or higher than a threshold value, the recovery means subjects the print head to the recovery operation.

摘要： In an image processing apparatus, a data amount of printing data generated for each different size of dot is reduced. Specifically, in quantization to obtain data for each printing head, printing data for a large dot is set as data in which a bit number per pixel is two bits, and printing data for a medium or small dot is set as data in which a bit number per pixel is one bit. Thereby, a data amount per pixel can be reduced compared with data in which all bit numbers per pixel for the large, medium and small dots are equally two bits.

摘要： When completing an image in a predetermined area by an odd or even number of bidirectional printing scans, this invention makes it possible to suppress lines of image defects and density variations and thereby print a high-quality image at high speed. In completing an image by an odd number of bidirectional printing scans, the print data for small ink droplets and large ink droplets are thinned using the first and second thinning pattern. The first and second thinning pattern thin the print data for small ink droplets and large ink droplets so that a difference between the total print ratio of all forward printing scans of the odd number of scans and the total print ratio of all backward printing scans of the odd number of scans when the first thinning pattern is used differs from that when the second thinning pattern is used.
