Abstract: A check pattern is printed which makes it possible to detect, with high precision, individual patterns corresponding to nozzles of a print head of an inkjet printing apparatus. More specifically, after an alignment mark is printed, ejection of an ink from the nozzles is stopped for a certain time. Because of this stoppage time, the concentration of a coloring material of the ink ejected from the nozzles increases, whereby the optical density of an analysis pattern which is printed later can be increased. In this manner, a scanner can read, with high precision, the patterns corresponding to the nozzles.

Abstract: In an inkjet printing apparatus, the colors of ink dots are controlled to make it possible to change the colors of an image to be printed. More specifically, ink temperatures, ink permeation speeds, and the capillary occupancy rates of inks in a print medium are used to control a permeation area formed by performing printing with preceding cyan and subsequent magenta, thereby controlling the colors realized by the inks which are ejected in an overlapping manner.

Abstract: An image processing apparatus executes color conversion so that when printing is performed based on image data compressed and decompressed with a lossy compression method, the image data reproduces expected colors of the image data before compression. More specifically, a range of a signal value of a black image affected by compression of image data, such as black character to be printed with black ink, is obtained, and a color separation table is generated such that color ink is not used but black ink is used within this range. This allows the image data to reproduce expected colors of the image data before compression when printing is performed based on the image data compressed and decompressed with a lossy compression method.

Abstract: In an overlapping head including a plurality of recording head chips overlapped to each other, a color shift can occur between a color recorded by an overlapping region and a color recorded by a non-overlapping region, which cannot be corrected by a density correction using head shading or the like. To correct such a color shift, a test pattern is recorded by the overlapping region and the non-overlapping region and colors of the recorded test pattern are measured. Color correction data to be used in correction of colors of an image to be recorded is generated based on a result of the measurement of the colors.

Abstract: In image processing, it is possible to suppress density fluctuation and keep graininess low as well as obtain a good balance of the processing load. More specifically, when dividing multi-valued data and generating two-pass multi-pass printing data, divided multi-valued data that is common to the two passes is generated in addition to the divided multi-valued data for each of the two passes. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each pass. Furthermore, when generating quantized data, a process of generating common data by the aforementioned data division, or a process of performing quantization first without dividing the multi-valued data and then dividing the quantized 2-pass data is selectively performed according to the printing position on printing medium.
