Patent ID: 8547613

Claim:
A method for compensating for print engine change to maintain color consistency in a document reproduction system, the method comprising: storing a fleet destination profile in a digital front end (DFE) of a cascaded color management system, said fleet destination profile having been constructed using a gray component replacement (GCR) strategy optimized for a given print engine of a document reproduction device; determining an amount of change in an output quality of said print engine; and in response to said amount of change being above a predetermined threshold: retrieving said fleet destination profile from said DFE which contains a L*a*b* to CMYK profile LUT; creating a 3-to-4 L*a*b* to CMYK profile LUT; concatenating said 3-to-4 L*a*b* to CMYK profile LUT with a fleet printer model to obtain GCR constrained 4-to-4 CMYK to CMYK profile LUT; generating CMYK values using said GCR constrained 4-to-4 CMYK to CMYK profile LUT; and providing said generated CMYK values to said print engine to maintain color consistency in said document reproduction device.
