摘要： One dither mask having a highest spacial frequency is selected from a plurality of dither masks. Next, a granularity is obtained with reference to a table based on the selected dither mask and an ejection amount level per area. Moreover, a difference in granularity between adjacent areas is calculated with respect to all of the areas. A maximum value is obtained out of the obtained differences in granularity, and then, the maximum difference in granularity is compared with a determination threshold. When the maximum difference in granularity is the threshold or greater, it is determined whether or not a dither mask having a spacial frequency lower than that of the selected dither mask is stored in a memory. When there are dither masks having lower spacial frequencies, a dither mask having a spacial frequency lower by one level than that of the selected dither mask is selected.

摘要： An object is to print a high quality image with resistance to print misalignment. To this end, the image processing apparatus generates quantized data for printing a first dot pattern and a second dot pattern in an overlapping manner. The first dot pattern and the second dot pattern are lattice patterns varying in a combination of two basis vectors. In a combined dot pattern obtained by combining the first and second dot patterns, there is a neighboring dot in which a dot in the first dot pattern and a dot in the second dot pattern are arranged at an interval smaller than a lattice spacing. The neighboring dot includes multiple neighboring dots varying in an approach direction.

摘要： A first dot pattern printed according to a result of quantization performed on a multi-valued grayscale value by using a first threshold matrix and a second dot pattern printed according to a result of quantization performed on multi-valued grayscale value by using a second threshold matrix are printed on a print medium in an overlapping manner. In order to generate the threshold matrices, a first initial pattern being a dot pattern corresponding to a first grayscale value and a second initial pattern being a dot pattern corresponding to a second grayscale value lower than the first grayscale value are generated for pixel regions of the first and second threshold matrices. Then, thresholds of the first and second threshold matrices are set such that dot patterns having continuity with the first and second initial patterns are obtained at grayscale values between the first and second grayscale values.

摘要： An inkjet recording apparatus includes a recording unit, an acquisition unit, a scanning unit, and a control unit. In the recording unit, a plurality of nozzles to which ink is supplied from a common liquid chamber is arranged in a first direction. The acquisition unit is configured to acquire image data. The scanning unit is configured to perform relative scanning with a recording medium in a second direction intersecting the first direction. The control unit is configured to control ink ejection operation of the recording unit. In a predetermined one time of relative scanning, the control unit uses a first nozzle, and does not use a second nozzle adjacent to the first nozzle in the first direction, for edge areas of a barcode including a plurality of bars in which a length in the first direction is longer than a length in the second direction.

摘要： In a printing apparatus configured to print an image by bidirectional multipass printing while using multiple print element rows that apply color material of the same color, a high-quality image suppressed in hue unevenness and density unevenness is printed. To this end, the printing apparatus forms first and second dot patterns on a print medium in an overlapping manner. In the first dot pattern, dot arrays in which first dot groups are arranged at an interval B1 are arranged in a nozzle arrangement direction while being shifted from each other by C1 in a scanning direction of a print head. In the second dot pattern, dot arrays in which the first dot groups are arranged at the interval B1 are arranged in a nozzle arrangement direction while being shifted from each other by C2 in the scanning direction of the print head. Here, values of C1 and C2 are different.
