Abstract
Disclosed is a registration system and a method useful for controlling and correcting the phase and position of simultaneously advancing webs having pre-printed objects spaced at a pitch length characterized by small but significant pitch variation to a target web. Also disclosed are consumer products, such as disposable absorbent articles including the preprinted objects which were previously included in the webs phased before combining with a target web by utilizing the instant registration system. The pre-printed objects may include pre-printed, pre-bonded, pre-applied, pre-cut, or pre-glued objects or elements of disposable absorbent articles or registration marks produced on a separate independent process not control-linked to the instant registration method. The registration marks may be visible or normally invisible to the human eye.
