What Defines Accuracy?

The idea behind G7 Neutral Print Density Color Control Methodology is: If our workflow is calibrated to neutral, any file we send through the process will come out neutral and accurate to the file. In Figure 2, I would remove the color cast in these images, but our job is to give the file's creator an accurate reproduction of their file. The constant questions challenging printers are: "Which one is accurate?" "Are my printing presses or prepress procedures adding the cast?" "Is the client's file yellow cast or blue cast?"

Print A in Figure 3 is correct to the client's file, printed with no cast added by the printer. I know this because the G7 Gray Bars prove the press is producing neutral results. Print B shows an example of a color cast to blue. If the client submitted a file with a blue cast, I would print it with a blue cast if my printing workflow prints to neutral. As stated previously, the definition of accuracy is printing to "neutral print densities."

Don Hutcheson, a top industry consultant, applied this definition to the most useful and accurate print methodologies in the world: G7. When a printer understands this simple concept, their print control world quickly becomes manageable. Also, you will not spend late nights at the press trying to understand why you can't match intended color targets. Remember this: The more confidence you have in your ability to accurately represent the original, the more profitable graphic reproduction becomes. Printing to G7 Neutral Print Densities provides this tool.
