Color management part 2--press fingerprinting

3. Applying the profiling data to modify the output from calibrated and profiled color proofers, filmsetters, and platesetters (separating, screening, distorting, etc.).

The shear number of ink/substrate/press combinations in package printing makes the term "fingerprinting" somewhat of a misnomer—there's no such thing as only one possible fingerprint per press. That's where averages are often used as a compromise and a place where some standards can help. For example, for years the commercial printing world has characterized a whole body of installed presses running to SWOP specifications under some generic sets of data.
