Disclosed is the use of a laser beam of any suitable wattage for the purpose of eliminating or drastically reducing edge bleeding; that is, discoloration, and for eliminating and drastically reducing edge dusting when, for example, carbonless sheets are cut. Presently, the mechanical cutting of carbonless sheets causes rupturing of the color forming capsules coated on the sheets, which produced visible edge discoloration extending inward from the edge to a distance of from up to 5 to 10 millimeters. This distracts from the appearance of the sheets and can also produce non-functional imaging in the edge areas when such sheets are used in electrophotographic imaging systems. A further problem associated with mech-anical cutting is edge dust, which, in turn, adversely affects the copying machine components within which the paper is being used for forming images thereon.
