摘要： When an image is recorded using a multichip recording head including a plurality of chips each having a plurality of nozzle arrays, a change in image density can occur due to a registration error between chips in an overlapping part where two chips are connected. To suppress the change in image density, input image data is distributed to two chips such that there are dots overlapping each other between the two chips in the overlapping part.

摘要： A first humidified gas is supplied through a first supply port to a sheet. A second humidified gas is supplied to a space where nozzles of an inkjet recording head are exposed through a second supply port located at a position closer to the recording heads than the first supply port, to increase atmosphere humidity in the space. The sheet portion having a moisture content increased by the humidification in advance is advanced into the space having the increased atmosphere humidity, to record on the sheet using the inkjet recording head. An amount of humidification with the first humidified gas is set according to at least one recording condition.

摘要： A cut mark is recorded in an area between one image and the next image to be printed, and the recorded cut mark is to be detected. When the cut mark cannot be detected, a position of the cut mark is estimated based on information on an already detected cut mark and information on a length of the image printed after said already detected cut mark. A first cut position and a second cut position for cutting off the area are set based on the estimation.

摘要： Multi-valued image data corresponding to a pixel area is divided into the first scanning multi-valued data, first and second scanning common multi-valued data, and second scanning multi-valued data. A quantization processing is executed on each of the multi-valued data to generate first scanning quantized data, first and second scanning common quantized data, and second scanning quantized data. After that, these pieces of quantized data are combined for each scanning to generate first scanning combined quantized data and second scanning combined quantized data. According to this, the amount of pixels where dots are both recorded by performing a scanning by plural times (the amount of overlapping dots) is controlled, and while suppressing the image density variations, the granularity is held to a low level.

摘要： Provided is an inkjet printing apparatus for performing a printing with a first nozzle array for ejecting a first color ink and a second nozzle array for ejecting a second color ink. The apparatus reduces density unevenness stemming from a sudden error in conveyance of a printing medium. When the apparatus performs a scan with respect to the printing medium for printing in which using ranges of nozzles in the first and second nozzle arrays are restricted to parts thereof, the restricted using ranges of the first and second nozzle arrays are shifted from each other. Thereby, the density unevenness stemming from the error in conveyance occur in positions which are different between the first and second colors, Thus, it possible to make the overall density unevenness less obvious by making gradients of variations in brightness and chroma of an image smaller.

摘要： There are provided an image processing method and an image processor which realize the processing of restricting image degradations such as “dot delay”, “banding” and “wind ripple” with a simpler circuit construction. Therefore, after the regular quantization processing is performed, in a pixel in a prohibition position the processing of limiting a predetermined quantized value to change into another quantized value is performed corresponding to the obtained quantized value and the position information of the pixel of interest. By doing this, even in the low level of the density value, it is possible to realize at a low cost the construction in which dots having different sizes are mixed for printing.

摘要： In a 2M-pass printing operation that forms dots including overlapping dots, this invention makes an arrangement to ensure that the number of overlapping dots that are printed in a unit area in pairs of passes each straddling a print medium convey operation executed between an Mth pass and an (M+1)st pass is greater than the number of overlapping dots that are printed in pairs of passes straddling any other convey operation. This arrangement can cause two dots of the overlapping dots to be separated from each other in the event of a print position misalignment, preventing a possible density fall even in a unit area where the largest density reduction is feared to occur at time of the print position misalignment.
