DuPont has made a number of significant additions to its range of Digital Cromalin proofers including the A3 iG2 and A2 iG4. Both machines feature a double set of ink heads which the company claims increases output speeds without compromising quality.
Both machines also use an extended gamut CMYK ink set, which according to DuPont, enables the proofers to match over 90% of standard Pantone colours including some metallic finishes.
At standard resolution the iG4 outputs an A2 sheet in around 24 minutes, in high-speed mode employing both sets of print heads this is decreased to 16 minutes, while a high resolution page takes 38 minutes.
The two machines are fitted with a set of ink reservoirs, each of which contains enough ink to allow the proofers to carrying on running for a further eight hours even if the ink cassettes are empty. This ensures that the machines can be left running over night without the risk of them running dry.
Orders have been taken for both machines at Drupa although DuPont has yet to announce the names of any of its customers.
DuPont is also showing a thermal transfer proofer. The Cromalin Thermal Contract produces digital halftone proofs output on a transfer sheet which can then be laminated onto a wide range of printing stock.
