Abstract

A method of printing an image on a foil-covered surface wherein a portion of the surface is coated with opaque white ink provides a unique high-quality graphic wherein the designs printed on bare foil are more prominently presented than, and are sharply differentiated from, designs printed on the surfaces coated with opaque white ink.

Claims

1. A method of creating a printed image on a boxboard base, comprising the steps of:

covering said boxboard base with foil using vacuum metalizing or glue lamination, over all or a portion of one surface;

printing one coat of opaque white ink on said foil-covered surface of said boxboard base in a single pass through said waterless offset printing press, such that less than the total surface area of said foil-covered surface of said boxboard base is coated with said opaque white ink; and

printing transparent ink on said foil-covered boxboard base in a single pass through a waterless offset printing press, such that an image is defined wherein at least a portion of said image is printed on said portions of said boxboard base which are coated with said opaque white ink and at least a portion of said image is printed on said portions of said boxboard base which are not coated with said opaque white ink.

2. The method of claim 1 wherein said base is solid bleached sulfite box board.

3. The method of claim 1 wherein said base is litho label.

4. The method of claim 1 wherein said base is recycled content box board.

5. The method of claim 1 wherein said base is paper stock.

6. The method of claim 1 wherein said base is news back box board.

7. The method of claim 1 wherein said base is synthetic paper.

8. A method of creating a printed image wherein at least one portion of said printed image is presented more prominently in comparison with other portions of said printed image, comprising the steps of:

Creating a primary offset photographic plate wherein the photographic surface of said primary offset photographic plate is coated with an ink-repellant surface in areas corresponding to said portion of said printed image to be presented prominently,

Creating at least one secondary offset photographic plate wherein the photographic surface of said secondary offset photographic plate is coated with an ink-repellant surface in areas which do not correspond to said portion of said printed image to be presented prominently;

Coating said photographic surface of said primary offset photographic plate with opaque white ink;

Coating the photographic surface of said secondary offset photographic plate with ink other than opaque white ink;

Contacting said primary offset photographic plate with a primary rubber blanket cylinder, wherein a reverse copy of said image defined by said primary offset photographic plate is transferred to said primary rubber blanket cylinder;

Contacting said secondary offset photographic plate with a secondary rubber blanket cylinder, wherein a reverse copy of said image defined by said secondary offset photographic plate is transferred to said secondary rubber blanket cylinder;

Contacting said primary rubber blanket cylinder with a foil-covered surface, wherein said primary rubber blanket cylinder transfers a positive copy of said image defined by said primary offset photographic plate to said foil covered surface; and

Contacting said secondary rubber blanket cylinder with said foil-covered surface, wherein said secondary rubber blanket cylinder transfers a correct copy of said image defined by said secondary offset photographic plate to said foil covered surface;

Whereby said printed image is presented on said foil-covered surface more prominently than on said other portions.

9. The method of claim 8 wherein said offset photographic plates are created by direct imaging technology.

10. The method of claim 8 wherein said offset photographic plates are created by electronic technology.

11. The method of claim 8 wherein said offset photographic plates are all positive acting plates.

12. The method of claim 8 wherein said offset photographic plates are all negative acting plates.

13. The method of claim 8 wherein at least one of said offset photographic plates is a positive acting plate and at least one of said offset photographic plates is a negative acting plate.
