Digital workflow processes
Embodiments of the present invention include a digital workflow process that is suitable for creating a product having a desired appearance according to a customer's instructions. Embodiments of the digital workflow process includes a digital prepress and printing workflow process for generating, manipulating, and processing image data and for printing such image data on a selected substrate. Embodiments of the present invention also include processes for creating an artwork file that designates opaque or transparent white inks and transparent color inks to be printed. Several embodiments also incorporate a metallic layer into the design for achieving specific design objectives.
1 . A method for printing an image on a substrate, the image having one or more ink layers when printed, the method comprising:
obtaining a substrate, the substrate having at least one surface on which the image will be applied;
digitally printing a white ink layer over a predetermined portion of the substrate surface; and
digitally printing one or more layers of ink over a portion of the printed white layer and/or the substrate surface, thereby generating the image on the substrate.
2 . The method of claim 1 , wherein at least a portion of the substrate surface includes a metallized or metallic layer, and wherein the white layer is digitally printed over at least a portion of the metallized or metallic layer.
3 . The method of claim 1 , further comprising
digitally printing a metallic ink layer with at least one metallic ink on the substrate surface via an ink jet printer.
4 . The method of claim 1 , wherein the white ink layer is digitally printed on the substrate using an ink jet printer.
5 . The method of claim 1 , wherein the white ink is opaque and the one or more layers of ink are transparent.
6 . The method of claim 1 , wherein the one or more layers of ink includes colored ink.
7 . The method of claim 1 , further comprising
digitally printing a layer of varnish over a portion of one of the layers of ink and/or the metallized or metallic layer.
8 . The method of claim 1 , wherein the substrate is selected from the group consisting of containerboard, fiberboard, linerboard, cardboard, paperboard, corrugated board, and styrene.
9 . The product made from the method of claim 4 .
10 . A method of generating print data in a digital computer system, comprising:
generating an artwork file within an image processing program, the artwork file comprising at least one image formed by one or more inks when printed on a substrate; and
creating a white opaque ink layer as a discrete layer within the artwork file, the white ink layer designated to be printed on the substrate via an ink jet printer using white ink before the at least one image is to be printed.
11 . The method of claim 10 , wherein the white ink layer is preserved as a channel so that the white ink layer can be printed using white ink.
12 . The method of claim 10 , creating a metallic color layer as a discrete layer that simulates a metallic appearance of a substrate to which the artwork file will be printed.
13 . The method of claim 10 , wherein the white opaque ink layer underlays a portion of the at least one image.
14 . A computer readable medium having computer-executable instructions for printing an image on a substrate, comprising:
a first component for instructing a white ink layer to be digitally printed on a surface of a substrate in select locations; and
a second component for instructing at least one other ink layer to be digitally printed on the surface of the substrate or the white ink layer, the one other ink layer creating the image on the substrate when printed.
15 . The computer readable medium of claim 14 , comprising
a third component for instructing a metallic ink layer to be digitally printed on the surface of the substrate prior to the white ink layer.
16 . The computer readable medium of claim 15 , wherein the first, second, and third components include instructions for the layers to be digitally printed by an ink jet printer.
