Abstract:
1. A method for performing finishing operations on at least one graphics area on a graphics sheet, the graphics sheet having a graphics side, an opposite process side, and reference features, the graphics side bearing the graphics area(s) and registration marks placed in predetermined positions with respect to the graphics area(s), the method comprising: positioning the graphics sheet on a sheet-receiving surface; sensing from the graphics side the positions of the registration marks at the time of the finishing operations; determining from the sensed positions the coordinates of the graphics area(s) with respect to the sheet-receiving surface as if viewable from the process side; and performing finishing operations from the process side of the graphics sheet based on such determination, whereby such process-side finishing operations compensate for variations of the graphics area(s) at the time of the finishing operations.
