Abstract:
A document contains a security element that combines a correlation mark and microgloss mark so that foreground pixels of the correlation mark are printed in a toner of a first color, and pixels of the correlation mark overwrite portions of the correlation mark in a second color, but neither the first color nor the second color appear on areas that correspond to background pixels of the correlation mark.
