US folding cartons and paperboard specialty firm Colbert Packaging has attained G7 Master stage in its manufacturing plants for reaching a graphic communications production environment.
The G7 Master level, conferred by a cross-platform global community Idealliance, is a benchmark for printing presses and proofing calibration in accordance with a common visual neutral grayscale appearance.
Colbert Packaging supports its clients with security inks and UV coatings, among others, for various packaging solutions.
Colbert Packaging president Jim Hamilton said: ""With G7 in effect in our facilities, we know that the branded packaging we produce for our customers will match any branded materials produced by their other G7-qualified suppliers."
A gray balance is a means to obtain a close visual match from the proof to press with an identical printed pattern irrespective of the technologies, presses and substrates in production.
Colbert Packaging vice-president of operations Bill Snyder said: "We print on a new Heidelberg offset press, a CPS flexographic press and various Mitsubishi, Mark Andy and Manroland presses.
"We use different types of paperboard, including SBS and recycled, as well as conventional, ultraviolet and soy-based inks, to produce custom folding cartons, rigid setup boxes, formed paper trays, labels, inserts and more."
