ABSTRACT:
A method for adjusting the gamuts of a set of printers to match the gamuts across a population of printers using mass targets. The method involves printing color patches suitably positioned in the color gamut with CMYK separations and simultaneously actuating DMA targets to the level 2 controls of the printers using closed loop control algorithms. An extreme MIMO control algorithm is used to converge to the desired L*a*b* targets by adjusting mass targets to the printing system in an iterative fashion to maximize the common intersection gamut across the printers.
