 G03G

Note(s)

  1. 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.
  2. The production of pictures by heat patterns exclusively, not using an electrostatic or magnetic pattern, is classified in group B41M 5/00.
  3. 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 B41M.
