If they don't see it at first, teach 'em about investigating special causes when a number penetrates a control limit in order to improve the process. If it's right, printers will grab it and run with it! Would that save time and materials and make for happier customers? What do you think?

Then I thought about all the times, when I was a printing CEO, that a publisher had demanded a credit for quality because the ad agency was beating him for a credit or "make good." Suppose I handed the customer a spreadsheet with all the numbers from all the samples from their job from such a system and let them see the process capability, the oscillations within the control limits and maybe an instance of a special cause where we shut the press down to investigate.
