Appeal 2006-1310
Application 10/657,320
least two print regions said two print regions exhibiting the same
color and the same color density and wherein the two print regions
have a rub-off ratio greater than 1.1.
9. The printed disposable paper product of Claim 8 wherein said
substrate is textured.
13. The printed disposable paper product of Claim 8 wherein said ink
comprises a pigment.
According to pages 5 and 6 of the Specification:
As used herein “printed element color density” refers to
the color density of each individual print element within the
image area of the printed substrate.
…
As used herein, “substrate color density”, [sic.] refers to
the color density of the unprinted areas of substrate. A non-
limiting example which illustrates this definition would be a
paper product printed by the flexographic printing process. For
a paper product printed by the flexographic printing process,
substrate color density would refer to the areas of the printed
paper product which do not comprise an image area (i.e.; the
unprinted areas of the paper product.
As used herein “background color density” refers to the
color density surrounding each individual print element within
the image area of the printed substrate. For example, when
printing images comprised of dots that are printed in
accordance with the prior art, in a given image area,
background color density is that of substrate color density. In
contrast, when printing according to the present invention,
background color density may be greater than that of substrate
color density and less than that of print element color density.
….
As used herein, “microscopic color density variation”
refers to the gradual variation in color density between a print
element and the background surround the print element. This
variation can be local in nature. [Emphasis added.]
