Note(s) This subclass does not cover constituent parts common to manifolding by means of pressure-sensitive layers or intermediaries, to apparatus or machines for duplicating or printing for office or other commercial purposes, or to addressing machines or like series-printing machines, which are covered by subclass Fulltext... Hierarchy... Expanded...B41F. In this subclass, as indicated by the references, groups Fulltext... Hierarchy... Expanded...B41L 15/00 and Fulltext... Hierarchy... Expanded...B41L 17/00 are intended to cover letterpress and lithographic printing apparatus only in so far as it is specially adapted for office or other commercial purposes; the general constructions or features of apparatus of these types are classified in subclass Fulltext... Hierarchy... Expanded...B41F. Constructions or features determining classification in these groups are, for example: ease of operation by clerical staff, cleanliness of operation in non-industrial environments, the use of printing surfaces constructed for the production of a limited number of copies. In this subclass, the following terms are used with the meanings indicated: "manifolding" means the obtaining of several copies simultaneously by means of pressure-sensitive layers when making an original; "duplicating" means the obtaining of successive copies from a master, e.g. a hectographic image; "stencilling" involves the use of a printing surface which is perforated to form the image, the ink flowing through the perforations on the copy material.
