Process Control Primer

Author: Joseph Marin

Printers have always had to deal with issues such as “Why is the color so inconsistent on these printed sheets?” and “The color on the press sheet doesn’t match the proof.” However, the only way to reproduce color more accurately and consistently is by applying process controls.

Process controls is the means by which you define a consistent and repeatable process by controlling variables through measurement and documentation in order to deliver the best possible quality product. To help you do this, the chapters in this Process Controls Primer break down the various production steps so you may analyze your production workflow and identify problem areas and their causes. By making the processes, tools, and measurements defined here a part of your workflow, you will gain more control of the entire color reproduction process. Sections include: • Introduction to process control • What you should know about color • Guidelines for print • Benchmarking your scanner • Color separation • Consistency in proofing • Consistency in CTP • Consistency on press • Bringing it all together
