Print buyers, agencies and marketers want to be able to make things “look the same,” regardless of where or how they’re printed. G7 is an improved method for matching color across multiple devices. It’s all about calibrating printing presses and proofing systems with the goal of repeatable, consistent color and images from proof to press, press to press and even facility to facility. The G7 specification is managed by IDEAlliance, and the biggest breakthrough is its emphasis on gray balance “target values” to monitor and control color.
The ‘G’ stands for the new calibrating Gray values and the ‘7’ for the core colors in our ISO printing rainbow: Cyan (C), Magenta (M), Yellow (Y), Black (K), Red (M+Y), Green (C+Y) and Blue (C+M).
For print buyers, G7 means that if you are working with two or three firms – say one in New Hampshire, one in Chicago and one in Texas – and all of them are G7 Masters, you can be more confident that the vibrant reds and yellows in your new marketing campaign will “visually match” across all three locations, regardless of whether it’s printed heatset web offset, sheetfed, inkjet or digital … and whether it’s a point-of-purchase display, brochure, self-mailer or packaging.
G7 has proven to be very adaptable and reliable across many printing processes, though I think you’ll find it most widely adopted in sheetfed shops right now. I can tell you that at Concord Litho, it’s getting us to color faster and more reliably on both our sheetfed and web presses, which is saving makeready time, reducing paper waste, and, best of all, making our customers happy. Three of our most color-conscious customers have raved about what their product looks like now compared to a year ago.
