In order to maximize Image Quality (IQ) in inkjet printers, it is required to ensure maximum dot placement accuracy on paper. Due to print head drop directionality, mechanical tolerances, etc. there's a need to calibrate dot placement error (DPE).This paper present a novel method to perform Automatic Printhead Alignment (APA) using color information, from combine several colors in an interference pattern instead of the current use of lightness information from color pairs interference patterns or positioning algorithms.
