A digital printing system having a linear printhead includes corrections for cross-track position errors. A data processing system implements a method for determining a cross-track position function which includes printing a test target including a plurality of alignment marks, automatically analyzing a captured image of the printed test target to determine a measured position for each of the alignment marks, comparing the measured positions for the alignment marks to reference positions to determine measured cross-track position errors, and determining a cross-track position correction function responsive to the measured position errors. The cross-track position correction function specifies cross-track position corrections to be applied as a function of cross-track position. A corrected digital image is determined by resampling the image lines of a digital image responsive to the cross-track position correction function.

A method for correcting cross-track position errors in a digital printing system having a linear printhead includes printing a test target including a plurality of alignment marks. A data processing system is used to automatically analyze a captured image of the printed test target to determine a measured position for each of the alignment marks. The measured positions for the alignment marks is compared to reference positions to determine measured cross-track position errors. A cross-track position correction function is determined responsive to the measured position errors, wherein the cross-track position correction function specifies cross-track position corrections to be applied as a function of cross-track position. A corrected digital image is determined by resampling the image lines of a digital image responsive to the cross-track position correction function.

An image forming apparatus includes a photosensitive member, a light source, a deflecting unit, a storing unit, a correcting unit, and a light source driving portion. Magnification correction data is determined using a quadratic function of a variable representing a scanning position with respect to a scanning direction. Coefficients of two quadratic functions corresponding to adjacent two regions included in a plurality of scanning regions are set so that a differential value calculated at the variable corresponding to a boundary of the two regions by a differential of the quadratic function for one region and a differential value calculated at the variable corresponding to the boundary of the two regions by a differential of the quadratic function for the other region are equal to each other.

A system, device and method for managing colors of a color printer in accordance with predetermined ink usages and cost objectives. Profiles comprising a corresponding set of job parameters are collected having an ink usage that satisfies a predetermined cost objective for the print job. Sheets are printed out in accordance with these acceptable profiles for proofing by a customer for image quality and selection of a profile to be used for the print job.

In an image recording apparatus, a peak load that is the highest load applied to a carriage moving in a first direction in a first load region is highest at a first highest-load position. A second load is highest at a second highest-load position of a second load region. In a retry processing, when a stop position of the carriage which is detected by a detector is located between the first highest-load position and the second highest-load position, the controller moves the carriage in the first direction toward a target position after moving the carriage from the stop position in a second direction to a first retry position located downstream of a restoration position in the first direction.

Example implementations relate to scan bar calibration. For example, a system for scan bar calibration may include instructions executable by a processing resource to implement a plurality of scanning settings at a scan bar index location of a scanning device. The system may further include instructions to execute a scan bar calibration of a calibration target at the scan bar index location, and generate a scan bar calibration table for the scan bar index location based on the executed scan bar calibration.
