A method for making a device link ( 90 ) for a color management system, with an associated imaging apparatus ( 20 ), wherein the device link specifies a transformation of digital-image colorant combinations to imaging-apparatus colorant combinations. The device link converts the digital image ( 70 ) to a modified digital image ( 100 ) represented using the imaging-apparatus colorant combinations, thereby allowing the imaging apparatus to produce an output image ( 170 ) having output-image colors matching reference-image colors at corresponding physical locations in a reference image ( 80 ). The method includes establishing an association between selected digital-image colorant combinations and reference-image colors, determining for each associated measured reference-image color a suitable imaging-apparatus colorant combination that will produce the reference-image color when rendered by the imaging apparatus, extending the transformation to all other digital-image colorant combinations by means of a mathematical interpolation, and encoding and encapsulating the transformation in a digital form as a device link.
