Abstract
A single ply carbonless form is provided where a sheet is divided into a first portion and a second portion. A coating of CF is applied to the first portion and a coating of CB is applied to the second portion, both on the same side of the sheet. A quantity of temporary tacking agent is applied to the back face of the sheet such that, upon folding the sheet in a manner where the CF and CB portions are not in contact with each other, the first portion is releasably held against the second portion. The form may then be sheet fed into a printing device, preferably using the folded edge as the leading edge. Subsequent to printing, the form may then be re-folded such that the CF and CB coating suitably line up for receiving impact impressions.
