For those print buyers wanting consistency in their product 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.  The G7 specification is managed by IDEAlliance. The G7 emphasis is monitoring gray balance target values in order to control color. 

At McCormick Armstrong we have both the sheet fed and web presses certified.  It gets us to color faster with greater reliability.  This saves make-ready time, reduces paper waste and, best of all, makes our customers happy with a higher quality product.

Customers benefit because they’re getting the very best color management available. G7 Master Printers have to prove that they can match proof, plates and press sheets to Idea Alliance.  G7 Master Printers don’t just rely on the human eye to adjust color.

By using G7, you are measuring color with spectrodensitometers, which provide accurate numbers of where you are printing. On our M600 Web, the press itself is monitoring Solid Ink Density, midtone dot gain, and gray balance as it is printing.  Not only does our M600 monitor these numbers; it is adjusting the ink as the press runs. No pressman in the world can see and adjust color on the fly this efficiently. Color has always been subjective, so why rely solely on human eyes when we at McCormick Armstrong have the latest equipment capable of measuring color so accurately?

The long and the short of it is you are getting the best color management system that is out today, better proof / press matches, faster make-readies, more consistent press runs, and job portability from printer to printer. Best of all peace of mind, because any printer that will go to all the trouble to get G7 certified will print a higher quality product day in and day out!!!!
