Systems and Methods for Reducing Color Registration Errors in Tandem Engines

A printing device comprising:

• a plurality of print engines including at least one first reference engine, the plurality of print engines being driven by a single pixel frequency and capable of printing color data;
• a memory coupled to the printer, wherein the memory holds calibration information for at least one second print engine relative to the first reference engine;
• and
• a processor coupled to the memory and the print engines, wherein the processor sends resolution adjusted color data to the at least one second print engine, the resolution adjusted color data being computed to offset color registration errors attributable to the at least one second print engine based on resolution information for color data processed by the first reference engine and the calibration information retrieved from the memory.

A computer-readable medium that contains instructions which, when executed by a processor, performs steps in a method of correcting color registration errors in a printing device comprising a plurality of print engines, wherein the plurality of print engines are driven by a single pixel frequency and include at least one first reference engine, the method comprising the processor implemented steps of:

• computing an adjusted resolution for color data to offset color registration errors attributable to at least one second print engine, wherein the adjusted resolution is computed based on calibration information for the at least one second print engine relative to the first reference engine and resolution information for color data for the first reference engine;
• adjusting the resolution of the color data for the at least one second print engine to the computed adjusted resolution;
• and
• printing the resolution adjusted color data using the at least one second print engine.
