Abstract
A method for registration of print separations in a printer comprising: (a) printing a first pattern, for which at least one image characteristic varies relatively weakly with misregistration, using at least one of first and second separations; (b) printing a second pattern, for which said at least one image characteristic varies relatively strongly with misregistration, using said at least one first and second separations; (c) determining said at least one image characteristic for the first and second patterns; and (d) correcting the mutual registration of said at least one first and second separations responsive to a difference in the determined at least one image characteristic for the first and second patterns.
