Processes for printing spot colors
The present disclosure relates to a process for printing comprising the steps of selecting eight or fewer process colors from a known process ink color set, providing a color channel for the selected process colors from the known process ink color set, providing two or more spot color channels, wherein one or more of spot colors correspond to a non-selected process color of the process ink color set, applying a first ink limit and a first linearization to the one or more spot color channels to produce a color set including the non-selected process color of the known process ink color set, applying a second ink limit and a second linearization to the one or more spot color channels to produce a color set including the spot color, and optionally printing an image.
1. A process for printing an image comprising:
identifying a known process ink color set comprising at least four colors;
selecting two or more process colors from the known process ink color set;
substituting each of the selected process colors with a spot color corresponding to the selected process color from the known process ink color set;
providing a color channel for each unselected process color and each spot color;
determining if the spot color is operating as the selected process color or the spot color; and
printing an image on a substrate;
wherein the color channel for the spot color is applied with a first ink limit and a first linearization corresponding to the selected process color;
wherein the color channel for the spot color is applied with a second ink limit and a second linearization corresponding to the spot color.
2. The process of claim 1 , wherein the color channel for the spot color is configured to operate as the selected process color when the first ink limit and the first linearization are applied.
3. The process of claim 1 , wherein the color channel for the spot color is configured to operate as the spot color when the second ink limit and the second linearization are applied.
4. The process of claim 1 , further comprising applying an ink limit and a linearization to the color channel comprising the unselected process colors.
5. The process of claim 1 , wherein the ratio of a number of substituted spot color channels to a number of process color channels is at least 0.5:1.
6. The process of claim 1 , further comprising providing one or more color channels for additional spot colors, wherein the additional spot colors do not substitute process colors from the known process ink color set.
