Abstract
A method for printing signs by printing a first ink layer directly on one face of a transparent substrate; applying an intermediate layer over the first ink layer; and printing a second ink layer directly on the intermediate layer.
Claims27
A method comprising of printing signs, comprising;
- printing a first ink layer directly on one face of a trasparent substrate;
- applying an intermediate layer over said first ink layer;
- and
- printing a second ink layer directly on said intermediate layer,
- wherein said first ink layer, said intermediate layer, and said ink layer are applied serially in a single pass of the substrate through a first ink jet printing station, a coating station for the intermediate layer, and a second ink jet printing station.
2 more elements
A method of printing signs, comprising:
- printing a first ink layer directly on one face of a transparent substrate;
- applying an intermediate layer over said first ink layer;
- and
- printing a second ink layer directly on said intermediate layer,
- wherein said first and second ink layers and said intermediate layer are all applied by liquid jet printers.
2 more elements
Apparatus for printing signs, comprising:
- an ink printing station including a plurality of nozzles for printing an ink layer directly on one face of a substrate;
- a coating station for applying a coating onto the ink layer;
- a substrate drive for driving the substrate first through said ink printing station and then through said coating station;
- and
- a second ink printing station downstream of said coating station, said second ink printing station also including a plurality of nozzles for printing a second ink layer on said coating.
2 more elements
A printed sign, comprising:
- a transparent substrate;
- an adhesive coating on a first face of the transparent substrate;
- a removable protective layer covering said adhesive coating;
- a first printed ink layer on the opposite face of said transparent substrate;
- an intermediate coating on said first printed ink layer;
- and
- a second printed ink layer on said coating;
- wherein said first ink layer, said intermediate coating and said second ink layer are applied serially in a single pass of the substrate through a first ink jet printing station, a coating station for the intermediate layer, and a second ink jet printing station.
5 more elements
A printed sign, comprising:
- a transparent substrate;
- a first printed ink layer of a first picture on one face of said transparent substrate;
- a coating of an opaque material over said first printed ink layer;
- a second printed ink layer of a second picture, different form said first picture, on said coating of said opaque material;
- wherein said first ink layer, said coating and said second ink layer are applied serially in a single pass of the substrate through a first ink jet printing station, a coating station for the intermediate layer, and a second ink jet printing station.
