For decades, printers’ approach to color management has been highly subjective. A proof is examined in a light box, compared to a press sheet, color keys are adjusted, and that was it.
In some cases, that works fine, but it can introduce errors and result in a job that may not be repeatable. For example, a job that needs to be reprinted may need to precisely match the first run.
If a different operator handles the second run, any variation can result in an unacceptable job.
What’s needed is to change color printing from a subjective “craft” process to an objective “manufacturing” process.
