Abstract
Aligning measurements taken by a second color measurement instrument with measurements taken by first color measurement instrument, wherein the first instrument has access to a first set of standards but not a second set of standards, and the second instrument has access to the second set of standards but not the first set of standards, includes using a third color measurement instrument to generate a profile that mathematically transforms a value measured on the second set of standards to a value measured on the first set of standards, wherein the third instrument has access to the first and second sets of standards, mathematically transforming measurements of the second set of standards taken by the second instrument into virtual measurements of the first set of standards, using the profile, and aligning the measurements taken by the second instrument to the measurements taken by the first instrument, using the virtual measurements.
