Abstract
The final-hardcopy operating facility, “target facility”, converts the content provider's original data file to a different color space to form a proofing data file. A proofing facility, which is distinct from the target facility, uses the proofing file to produce a visible proof for viewing by the content provider, customer etc. A common proofing file is applied to both preparing the proof and printing the final hardcopy. Because it is the target facility rather than the content provider or the proofing facility that prepares the proofing file, using maximum available knowledge about the printing equipment which will be used and its color characterization and other technical behavior, this approach gives maximum assurance that the final hardcopy will represent the proof as accurately as practical.
