This article presents brief overview of the benefits of a color management system and the requirements to implement color management in a printing facility, as well as the answers to some commonly asked questions.

Before a color management system can even be considered, systematic process control must be in place. If your presses and operators are unable to print consistently, the whole effort will be a frustrating exercise in chasing your tail.

Papers and films should be inspected to ensure that they have the same print characteristics: whiteness, clarity, smoothness, hold-out, surface treatment, etc., based on your printing needs. Inks should have the same density, hue, color strength, and print performance criteria. Your suppliers should be able to document quality checks on their products. If you receive your plates from a trade shop, they should also be able to demonstrate that the plates are made the same way each time, with consistent relief and dot structure. If you make your plates in house, measure the plates you produce. Know what the dot size for your control targets should be on the plate and ensure that it measures the same every time.
At the press, operators should follow standard setup procedures. Blades should be inspected, pH and viscosity must be adjusted to meet specifications, anilox rolls must be cleaned thoroughly after each run to ensure that...
