Abstract
An apparatus associated with a printing device having a plurality of print engines comprising a first print engine and at least one second print engine is provided. The apparatus comprises a pixel clock generating module which generates a reference signal operating at a single video frequency derived from a first clock and the at least one first print engine. The apparatus further comprises a color data modification module which modifies the color data for the at least one second print engine based on an accumulated phase error for at least one second print engine, wherein the accumulated error is calculated based on calibration information for the at least one second print engine relative to the at least one first print engine.
