摘要： An image processor, a printing apparatus, and an image processing method are provided that can reduce, when a plurality of types of inks are used to print an image, the color unevenness that is caused by the variation of ejecting characteristics among a pluralities of nozzles. To realize this, for a color formed by overlapping at least two colors of inks, parameters are prepared that are determined so as to reduce the color difference in the printing medium due to the variation of the ejecting characteristic among the respective pluralities of nozzles. During printing, the parameters are used to correct the first color signal owned by the individual pixels to the second color signal.

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： Provided is an image processor and image processing method that are capable of suppressing both density unevenness and graininess that occur due to deviation of the printing position of dots that are printed by a plurality of relative movements (or a plurality of printing element groups). In order to accomplish this, the dot overlap rate of an image characteristic in which density unevenness stands out is made higher than the dot overlap rate of an image characteristic in which other defects stand out more than the density unevenness. By doing so, it is possible to suitably adjust the dot overlap rate according to an image characteristic, and to output an image having no density unevenness or graininess.

摘要： The present invention suppresses data processing load and processing time when generating density data for the same color that corresponds to a plurality of printing scans (or plurality of printing element groups) of a printing head and printing medium. In order to accomplish this, input image data is converted to a plurality of density data by referencing a three-dimensional lookup table that performs one-to-one correlation of input image data with a plurality of density data that corresponds to a plurality of relative movements (or plurality of printing element groups). By doing so, it is possible to perform a process of generating density data (CMYK) that corresponds to a plurality of relative movements (or plurality of printing element groups) from input image data at once, and thus it is possible to suppress an increase in data processing load and processing time.

摘要： Inputted image data is converted to M number of multi-value data having a lower resolution than the inputted image data, and after quantization processing has been performed for each of the M number of multi-value data, an image is printed by M number of relative movements (M-pass printing) that corresponds to the M number of quantized data. By doing so, when compared with the case in which a resolution reduction process is not performed, it is possible to suppress the number of pixels that become the object of quantization processing, and it becomes possible to output an image with no fluctuation in image density or density unevenness without a decrease in the processing speed.

摘要： Provided are an image processor and an image processing method that are capable of suppressing both density unevenness due to printing position shifts among a group of dots printed by a plurality of relative movements (or a plurality of printing element groups) and graininess. In order to accomplish this, a dot overlap rate in the printing mode in which the density unevenness stands out is made higher than the dot overlap rate in the printing mode in which other defects stand out more than the density unevenness. By doing so, it is possible to suitably adjust the dot overlap rate according to the image characteristic, and output an image having no density unevenness or graininess.

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.

摘要： When the width of a recording head is greater than the width of a recording medium having a maximum conveyable width, a recorded image corresponding to ejecting ports in the entire area of the recording head cannot be corrected. Multiple correction test patterns are recorded using ejecting ports in part of the recording head, and correction data for correcting an image corresponding to ejecting ports in the entire area of the recording head on the basis of the colorimetric result of the test patterns. In this way, image data to be recorded by the ejecting ports in the entire area of the recording head is corrected.

摘要： Before a printing operation, printing conditions related to occurrence of mist are acquired. According to the printing conditions, mist reduction device and a mist-reduction correction amount for controlling a degree of reducing the mist by the mist reduction device are set. Thereafter, printing is performed on a print medium by use of the set mist-reduction correction amount and mist reduction device. Accordingly, an appropriate mist reduction method is adopted according to the various printing conditions. Thus, optimum printing can be executed without impairing image quality or user-friendliness more than necessary.
