You gain a significant competitive edge when your workflow is efficient and replicable — especially when it comes to meeting color expectations from proof to print. The G7 Methodology from Idealliance is a global specification for CMYK process, that is used to consistently hit clients’ color targets. ISO estimates more than 50,000 printers worldwide implement and maintain G7 based workflows. In fact, G7 is a required certification by many leading print buyers.
The name G7 stands for “Gray”, plus the 7 colors of primary and secondary solid ink values: Cyan, Magenta, Yellow, Black (CMYK), and Red, Green, and Blue (RGB). It controls two aspects, tonality and gray balance, in order to define a shared visual appearance for printed grays. By controlling these elements, printers can more precisely control production colors. Additional benefits of implementing the G7 methodology include a significant time and cost savings because it brings all systems and processes in control with repeatable, predictable results — meaning less wastage of material, less approval cycles, less color-matching time needed for press set-ups, and many more benefits.
Over the past several years, I have been involved in optimization and calibration of various printing processes across different plants with varying complexities. For example, substrates covering paper, board, plastic films with different structures, printing technologies covering offset, flexo, gravure, digital printing and ink types covering solvent-based, water-based, UV inks etc. It’s good to see in practice how G7 provides consistent visual appearance across these multiple complex printing conditions with a common set of aims, while offering the flexibility through different compliance levels.
G7 calibration is also an easy-to-manage established starting point, so any four-color print condition can be easily calibrated to ensure consistent output, whether or not you use additional color management. The characterized reference printing conditions (CRPCs) of ISO-PAS 15339 are globally recognized and all based on G7, which simplifies communication and reproduction of color content across the entire supply chain from print buyer, designer, prepress to print production.
When you attend G7 Training to become certified, or when you have a certified G7 Expert or G7 Professional on your team, you can then move to become an Idealliance Qualified Master Facility, which will allow you to actively manage your production, align your supply chain, and take advantage of the globally recognized benefits of G7 status as a leading print facility, opening up additional opportunities to serve major brands around the world.
