Abstract
An automated method for proofing a page for color discriminability problems includes converting a first color of a first object appearing on the page and a second color of a second object appearing on the page to a perceptually uniform color space. The method includes identifying a difference between the first color and the second color in the perceptually uniform color space. The method includes comparing the difference to a threshold to determine if the first color and the second color are discriminable.
Claims36
An automated method for proofing a page for color discriminability problems, the method comprising:
- converting a first color of a first object appearing on the page and a second color of a second object appearing on the page to a perceptually uniform color space;
- identifying a difference between the first color and the second color in the perceptually uniform color space;
- and
- comparing the difference to a threshold to determine if the first color and the second color are discriminable.
A system for automatically identifying color discriminability problems of objects appearing on a page, the system comprising:
- a memory for storing the page;
- and
- a processor coupled to the memory for converting a first color associated with a first object on the page and a second color associated with a second object on the page to a perceptually uniform color space, and identifying whether the first color and the second colors are discriminable based on a difference between the first and the second color in the perceptually uniform color space.
A system for proofing a page for color discriminability problems, the page including a first object and a second object, the system comprising:
- means for converting a first color associated with the first object and a second color associated with the second object to a perceptually uniform color space;
- means for identifying a difference between the first color and the second color in the perceptually uniform color space;
- and
- means for determining whether the difference is greater than a threshold, thereby indicating that the first color and the second color are discriminable.
A computer-readable medium having computer-executable instructions for performing a method of identifying color discriminability problems of objects appearing on a page to be printed, comprising:
- identifying a first color associated with a first object appearing on the page;
- identifying a second color associated with a second object appearing on the page;
- converting the first and the second colors to a perceptually uniform color space;
- and
- determining whether the first color and the second color are discriminable based on a difference between the first and the second colors in the perceptually uniform color space.
