DiamondTopTM 1C

Flexibility is just part of the package.

High marks from high graphics users. That’s the word on our DiamondTop 1C. This remarkable product enables high print gloss and rich ink density. No matter the type of corrugating or printing equipment, customers rave about its superior runnability and convertibility. Featuring a light clay coating, it’s even post-printable in many cases without the aid of dryers. Yet it’s still suitable for the graphic demands of preprint applications. Now, that’s what you call flexibility.
