Abstract: A method for continuously producing a plurality of printed and activated time dependent labels. In one embodiment, the method comprises providing a web having a plurality of inked substrates thereon. Each substrate has a migrating ink pattern printed on a surface of the substrate. A transfer printer is provided that has a first ribbon means for applying a timing layer through which the migrating ink bleeds after a predetermined period of time. A second ribbon means is provided for printing variable data. The web of inked substrates is continuously fed through the printer, each inked substrate passing sequentially under the first ribbon means and then the second ribbon means. The first ribbon means is activated to apply the timing layer to a portion of the printed surface of each inked substrate thereunder to produce a coated substrate.

Abstract: Sheet material (20,20') including a polyvinyl fluoride film (21), an application tape (22) removably adhered to one surface (32) of the film (21) and a carrier tape (23) removably adhered to the application tape (22). The polyvinyl fluoride film (21) has an exposed surface (33) on which a sign (4) is printed in reverse image. Adhesive (42) is applied over the printed surface (33) with a transfer tape (40). When printed film (21) is applied to a selected surface, the film (21) is adhered to the selected surface by adhesive (42) after separation of the carrier tape (23) and application tape (22) so that the printed sign (4) is on the innermost surface (33) of the film (21) and protected by the thickness of the polyvinyl fluoride film (21).

Abstract: Sheet material (20,20') including a polyvinyl chloride film (21), an application tape (22) removably adhered to one surface (32) of the film (21) and a carrier tape (23) removably adhered to the application tape (22).
