Abstract:
1. A method of converting a first recipe using a first colorant set to a second recipe using a second colorant set in a digital color proofer system wherein a recipe is a data file defining a color and including at least a set of colorant values of a colorant set, comprising the steps of: converting the first recipe into a CIE_Lab (Commission Internationale de l'Éclairage L*a*b*) estimate for the digital color proofer system using a first model and a first database comprising at least one page defined as an array of data points containing at least one first recipe; converting the CIE_Lab estimate into the second recipe in the digital color proofer system using a second model and a second database wherein the second database comprises at least one page defined as a second array of data points with a determined center of the second array and surface points from the second database wherein at least one second recipe corresponds to the first recipe; selecting a second recipe having a maximum accuracy estimate from the at least one second recipe in the second database; and providing the second recipe and the accuracy estimate to a user and storing the second recipe and the accuracy estimate.
