Abstract

A partially printed substrate with a print pattern comprising a first color deposited on the substrate and a second color deposited on the first color, the second color being darker than the first color, whereby the first and second colors are perceived as a combined, substantially single color in the area defined by the first color.

Claims

1. A method of printing a panel comprising:

providing a sheet of transparent material;

printing select areas of said transparent material with a print pattern;

scanning said sheet of transparent material and said printed select areas thereon so as to identify leading edges and trailing edges of said printed select areas; and

instructing a digital printing machine to print a superimposed layer on select portions of said printed select areas, and wherein said instructing is based on said identified leading edges and trailing edges of said printed select areas.

2. A method as claimed in claim 1, wherein said digital printing machine uses a Raster Image Processor for enabling the positioning and size of deposits of black, cyan, magenta and yellow marking material in a four color process to form said superimposed layer.

3. A method as claimed in claim 2, further comprising instructing said digital printing machine so that it does not print on any unprinted areas of said transparent material.

4. A method as claimed in claim 1, wherein said print pattern comprises a plurality of lines.

5. A method as claimed in claim 1, wherein said print pattern is opaque.

6. A method as claimed in claim 4, wherein said transparent material is fed for printing by said digital printing machine in a direction perpendicular to said lines.

7. A method as claimed in claim 1, wherein said print pattern comprises a layer of white material and a layer of black material.

8. A method as clamed in claim 7, wherein a layer of clear material is applied to said white material, said clear material being receptive to a marking material.

9. A method as claimed in claim 1, wherein said digital printing machine is a thermal transfer digital printing machine.

10. A method as claimed in claim 1, wherein said digital printing machine is an ink jet digital printing machine.

11. A method as claimed in claim 1, wherein said print pattern comprises a plurality of layers.
