The method involves preparing a printed object equipped with control elements (92, 93, 94), where the elements comprise two patterns at the recto and verso of the object, respectively. The control elements are examined by transparency. Offset sectors of one of the patterns are respectively hidden or visible between geometrical forms of another pattern, during examination of the control element, after detecting whether a recto-verso register is correct or incorrect. An independent claim is also included for a method for adjusting a recto-verso register of a printed object. |
