摘要： A method (100) and means for automatic alignment of ink-jet printheads includes fitting measuring constructs (401, 503, 505, 601) to actual print data acquired form a print made using a given, predetermined, test pattern data set. Specific test patterns (701, 801-805) for use in automated alignment of ink-jet printheads are suited to providing a variety of printhead alignment information in a compact format. The test pattern data set incorporates techniques for avoiding carriage-induced dynamic errors during automated alignment of ink-jet printheads.
