(under the class definition) Apparatus comprising a frame-like holder carrying a transparent sheet particularly adapted for the application of ink or other fluid to a base member to be made into a printing plate.
(1) Note. These devices generally comprise a holder for a transparent plate onto which is applied the ink in the form of dots, etc., and such dots are subsequently transferred from the plate to the work. The holder is usually provided with some kind of micrometer lateral adjustment to provide for movement of the plate to and from the work in a special relationship to a previously applied design by the same or different plate.
