Diamond Proof Premium Quality Proofing Media

From proof to proof, Mitsubishi Imaging Diamond Proof media performs consistently and rivals the best in the industry. That’s not surprising since Mitsubishi pioneered specialty inkjet papers more than 30 years ago and has over 100 years of experience in the paper business.

Mitsubishi’s unique engineering process has made Mitsubishi Diamond Proof media the right choice to provide graphic arts professionals the consistent quality proofing results they demand. As a premium proofing media, the base layer of the Diamond Proof papers has extra dimensional stability, enabling the papers to absorb the heavier ink lay-down of today’s wide format printers.

Diamond Proof media comes in a complete assortment of substrates and coatings for varying proofing applications and is perfectly matched and designed for today’s inkjet printers. Our newest Contract Proofing Papers conform to the latest printing standards such as GRACoL, SWOP and FOGRA. ICC profiles for our media have been developed and are available with key third-party printer partners.
