Abstract: A registry device is described having a transparent cover having positioning indicia thereon and an underlying substrate between which printed copy may be placed for determining alignment corrections. Preferably a spacer lies between the cover and the substrate which is preferably approximately the thickness of the copy whose printing alignment is to be determined using the device. Most preferably, the spacer is a reference guide against which a sheet of copy may be placed when determining alignment, using the markings on the second substrate, although the reference guide may be separated from the spacer, or used in place of the spacer.
