Abstract

A system and method for determining a color separation registration error in a multi-color printing system are provided. The system and method provide for instructing first and second color separations to mark a substrate with first and second fine-periodic-patch images to determine color separation registration error(s). The system and method further provide for determining whether at least an about half-period color separation registration error exists between the first and second color separations.
