Abstract

A method for preparing a graphic on a sheet (40) of material which also includes at least one registration mark (44) at and about the graphic in predetermined positions. The method involves the steps of applying the graphic (42a, 42b) and at least one registration mark on a sheet of material in positions according to layout data, transferring the layout data to a processing controller, placing the sheet of material on a sheet-receiving surface (16), sensing the position of the registration mark on the sheet of material, and utilizing the layout data and the position of the registration mark to precisely narrow-path-process around the graphic on the sheet of material. Certain embodiments use either (a) a subset (46) of marks which is applied on one side of the graphic or (b) certain reference features, such as edges and corners of the sheet and elements of the graphic, to ascertain the position and orientation of the sheet on the apparatus. The invention provides efficient, rapid, automated, and precise processing around the graphic.

Description

RELATED APPLICATION

[0001] This is a continuation of patent application Ser. No. 10 / 283,460, filed Oct. 30, 2002, issuing on May 9, 2006 as Patent No. 7,040,204, the contents of which are incorporated herein.FIELD OF THE INVENTION

[0002] This invention is related generally to the field of cutting of graphics or the like from sheets for various purposes, and other narrow-path-processing about graphics on sheets. BACKGROUND OF THE INVENTION

[0003] The technical field involving the cutting of graphic areas from sheets, or otherwise doing narrow-path-processing about graphics images on sheets, includes, for example, the face-cutting of laminate sheets to form decals. More specifically, a graphic on the face layer of a laminate needs to be cut away from the remainder of the face layer so that the graphic (decal) can subsequently be pulled away from the backing layer of the laminate and be applied elsewhere as intended. Highly accurate face-layer cutting about the graphics is obviously hi...
