Patent number: 11138482Abstract: A digital printing system having a linear printhead includes corrections for in-track position errors. A data processing system implements a method for determining an in-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 in-track position for each of the alignment marks, comparing the measured in-track positions for the alignment marks to reference in-track positions to determine measured in-track position errors, and determining an in-track position correction function responsive to the measured in-track position errors. The in-track position correction function specifies in-track position corrections to be applied as a function of cross-track position. A corrected digital image is determined by resampling an input digital image responsive to the in-track position correction function.Type: GrantFiled: September 9, 2019Date of Patent: October 5, 2021Assignee: EASTMAN KODAK COMPANYInventors: Chung-Hui Kuo, Brian B. Mix, Michael Thomas Dobbertin

Patent number: 11126107Abstract: 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.Type: GrantFiled: May 21, 2019Date of Patent: September 21, 2021Assignee: EASTMAN KODAK COMPANYInventors: Chung-Hui Kuo, Brian B.

Patent number: 10062017Abstract: A print engine is adapted to print image data from a plurality of pre-processing systems that supply image data at different image resolutions and halftoning states. A data interface receives the image data and associated metadata including an image resolution parameter and a halftone state parameter. A metadata interpreter interprets the metadata and determines image processing operations that are required to prepare the image data for printing using a printer module. A resolution modification processor module processes the image data to modify its resolution if the metadata interpreter determines that the image resolution of the image data does not match the printer resolution. A halftone processor module processes the image data by applying a halftoning operation if the metadata interpreter determines that the image data is not in an appropriate halftoning state.Type: GrantFiled: April 22, 2016Date of Patent: August 28, 2018Assignee: EASTMAN KODAK COMPANYInventors: Chung-Hui Kuo, Stacy M. Munechika, David R. Brent, Frederick Edward Altrieth, III, Brian B. Mix
