Abstract
Systems and methods are provided for correcting color registration errors in a printing device comprising a plurality of print engines driven by a single pixel frequency clock. In some embodiments, the print engines can include a reference print engine and one or more non-reference print engines. An adjusted resolution may be computed for color data sent to each non-reference engine to offset color registration errors attributable to the non-reference engine. The adjusted resolution is computed using calibration information for the non-reference print engines relative to the reference engine, and resolution information for color data processed by the first reference engine. The resolution of color data processed by each non-reference print engine is adjusted according to the computed adjusted resolution for the non-reference engine and sent to the print engines for printing.
