Spot color control method, apparatus and system

摘要

This disclosure provides spot color control methods, apparatus and systems. According to one exemplary embodiment, disclosed is a method of generating device dependent color recipes for a plurality of printing devices. The method includes generating a first device dependent recipe for a target color for rendering on a first printing device, and generating a second device dependent recipe for the target color for rendering on a second printing device, whereby the second device dependent recipe is a function of the first device dependent color recipe.

1. A method of generating multidimensional device dependent color recipes for a plurality of printing devices operatively connected to one or more controllers, the one or more controllers configured to perform the method comprising:
A) generating a final first multidimensional device dependent colorant recipe for a device independent target color for rendering on a first printing device, the final first device dependent recipe iteratively calculated to render the device independent target color on the first printing device using an initial first device dependent recipe and a first GCR process from a plurality of GCR processes, each of the plurality of GCR processes associated with a respective gamut class of the first printing device; and B) generating a final second multidimensional device dependent colorant recipe for the device independent target color for rendering on a second printing device, whereby the final second multidimensional device dependent colorant recipe is iteratively calculated to render the device independent target color on the second printing device using the final first multidimensional device dependent colorant recipe associated with the first printing device as an initial estimate of the final second multidimensional device dependent colorant recipe, whereby the use of the final first multidimensional device dependent color recipe associated with the first printing device as the initial estimate forces the use of the first GCR process from the plurality of GCR processes to generate the final second multidimensional device dependent colorant recipe for the device independent target color for rendering on the second printing device, each of the plurality of GCR processes also associated with a respective gamut class of the second printing device, wherein the final first and final second multidimensional device dependent colorant recipes associate the device independent target color with respective final first and second multidimensional device dependent color space representations of the target color.
