Abstract
A carbonless form is provided that may be folded selectively into a duplicating state or a non-duplicating state. In accordance with one embodiment of the present invention, a carbonless form is provided comprising a form sheet, a transverse fold line, an assigned data entry portion, and an exposed data entry portion. The form sheet defines a front face, a rear face, a top edge, a bottom edge, and a pair of side edges. The transverse fold line extends across the form sheet to define a first panel and a second panel on opposite sides of the transverse fold line. The assigned data entry portion is defined on the rear face of the second panel. The exposed data entry portion is defined on the front face of the first panel. A CB coating is applied to the rear face of the form sheet in the first panel and a CF coating is applied to the rear face of the form sheet in the second panel. The transverse fold line, the CB coating, and the CF coating are arranged such that the form sheet may be folded selectively about the transverse fold line into either a duplicating or a non-duplicating state. The duplicating state is characterized by juxtaposition of the CB and the CF coating. The non-dupli…
