Abstract: A method for aligning multi-channel digital image data for a digital printer having a plurality at least one printhead is described. One or more spatial adjustment parameters are determined for each of the printheads. The spatial adjustment parameters can be determined by comparing locations of test pattern indicia in a printed test pattern to predefined reference indicia locations. Digital image data for the non-reference printheads is modified by designating an input pixel neighborhood within which an image pixel should be inserted or deleted, comparing the image pixels in the input pixel neighborhood to a plurality of predefined pixel patterns to identify a matching pixel pattern; and determining a modified pixel neighborhood responsive to the matching pixel pattern.

Abstract: A control device performs: acquiring an optical measured scan value; setting a measured offset using the measured scan value by reference to predetermined correlations; and determining a control value using the measured offset amount. The control value is used for controlling an amount of colorant to be ejected during printing. In the predetermined correlations, a first pair of scan values is associated with a first pair of offsets. A second pair of scan values is associated with a second pair of offsets. The first and second pair has a first and second scan difference between the scan values, respectively. The first and second pair of offsets has a first and second offset difference between the offsets, respectively. The first scan difference is different from the second scan difference. The first offset difference is same as the second offset difference.

Abstract: An image reading apparatus includes an image reader, an image adjuster and an execution controller that causes the image reader to read an adjustment document and causes the image adjuster to adjust image data generated by the image reader. The adjustment document includes line images and parameter images at positions spaced apart in a main scanning direction in a margin area where the line images are not provided. The parameter images indicate parameters used in image adjustment processing. The execution controller judges whether the image data corresponding to predetermined positions in the main scanning direction coincide, selects one of the image data judged to coincide, and causes the image adjuster to perform the image adjustment using the selected image data and the parameter indicated by the image data generated by reading the parameter image at the position in the main scanning direction of the selected image data.

Abstract: An image processing apparatus includes an image forming unit, an image control unit, a sensor, and a correction unit. The image control unit controls the image forming unit to perform toner refresh which is an operation of outputting deteriorated toner at a high density, and controls the image forming unit to form a predetermined pattern. The sensor measures a density value of the formed image. The correction unit corrects the toner density for a high-density operation using the value measured from the image formed during the toner refresh and corrects the toner density for at least a low-density operation using the value measured from the predetermined pattern.
