ELECTROGRAPHY; ELECTROPHOTOGRAPHY; MAGNETOGRAPHY (thermoplastic recording of information Fulltext... Hierarchy... Expanded...G11B, Fulltext... Hierarchy... Expanded...G11C; thermoplastic recording of television signals Fulltext... Hierarchy... Expanded...H04N 5/82)

|  | G03G |
Note(s) This sub-class deals with the production of permanent directly-visible pictures in conformity with an original picture or document, using an imagewise distribution of an electric or magnetic quantity, such as a charge pattern, an electric conductivity pattern, or a magnetic pattern. The production of pictures by heat patterns exclusively, not using an electrostatic or magnetic pattern, is classified in group Fulltext... Hierarchy... Expanded...B41M 5/00. The production of prints by transferring ink from a printing form to a printing surface, without physical contact and using the force of an electrostatic field, is dealt with in sub-class Fulltext... Hierarchy... Expanded...B41M.
