Abstract: A method for correction of non-impact printed matter which is formed by depositing a thermoplastic marking material on the print sheet. The method uses a correction tape or ribbon comprising a substrate which carries a pressure transferable opaque, adherent pigmented material on one face. The correction ribbon is positioned between the erroneously printed character and a correction device which is actuated to produce sufficient pressure to move the correction ribbon into intimate contact with the erroneously printed character. The pigmented material is transferred selectively only to cover the erroneously printed character so that the correct character can then be printed and is not transferred to the remainder of the character area. In an alternate embodiment, the correction device is actuated concurrently with a backspace operation.
