Abstract
Sheets of material, such as paper, having one one face a coating A of image-forming material (such as the CB coating of a carbonless copy system) are formed into pairs (51,52) connected together along one edge (53), by folding or by means of adhesive, with the coated faces (51a, 52a) in face-to-face contact leaving the remaining faces (51b, 25b) exposed, and such double sheets (50) are formed into stacks for use in non-impact printing processes by a method in which the printing is performed successively on the two exposed faces of the pairs of sheets and the two sheets are then separated.
