Abstract
The copying system comprises a plurality of units in a stacked configuration, where each unit comprises two or several sheets of carbonless, repositionable self-adhesive paper. Image transfer upon writing pressure results in copies of the message made in a single unit but not on subsequent units in the stack. Image transfer is controlled by regulating the microcapsule size of the carbonless copying component on the first sheet in each unit and the basis weight of the last sheet of paper in each unit.
