Closed-loop scanner measures and corrects key quality criteria

DCOS Sweden AB’s fourth generation CRC4 multi-function scanner launched during drupa will be featured on NR1 Trykk’s new manroland UNISET press scheduled for installation later this year in Biri, Norway.

“We could see the advantages of one closed-loop scanner that measures and immediately corrects the key quality criteria – colour-to-colour register, density, dot gain, fan-out and print defects,” explains Olav Engum, project director at NR1 Trykk. “The CRC4 scanner will be integrated with the manroland PECOM control system on the four tower, one-folder UNISET press. A simple concept that uses densitometry instead of colour measurement, the technology offers excellent performance yet is highly cost effective. With the aid of a motorised profile bar, the intelligent scanner swipes the entire web width to pick up online data. The collected inspection data also detects paper toning (scumming) and web wrinkles.

“Developed for high-speed newspaper production, the CRC4 uses high intensity LEDs for better contrast and the scanner’s compact design makes it possible to mount on an unsupported web between idle rollers,” says Mattias Andersson, managing director of DCOS. “With lower upfront equipment costs and the efficiencies gained during production, the CRC4 offers exceptional cost benefits.”

“NR1 Trykk has worked with DCOS on a number of projects so we’re confident with DCOS’ capabilities and exceptional management of its various technologies,” concludes NR1 Trykk’s technical manager Sven K. Johansen.
