ON-PRESS CONTROLS

AVT
Hall 3, Stand B69
Advanced Vision Technology (AVT) is launching a new range of products at Drupa, including a new on-press, inline spectral measurement system SpectraLab. Also new is the PrintVision/Argus Elite system for packaging applications and the RightSeal system for cold-seal monitoring. The company aims to "redefine" commercial web offset inspection with its PrintVision/Neptune setup which continuously inspects both sides of the web.

DCOS
Hall 16, Stand D59
Swedish on-press controls manufacturer DCOS will highlight the latest addition to its offering: online closed loop density control. This system will be officially launched at the show. The company says market price will be around 50% of conventional systems, targeting newspaper printers and developed for coldset printing. Measurement, it says, will be in micro mark dots, rather than image based and it will be available standalone or as integrated part of DCOS control system package.

KBA
Hall 16, Stands C47 1 & 2
KBA will showcase new features including the new KBA QualiTronic Mark Plus inline sheet single marking system and inline colour control on the RAPIDA 75E.

Ryobi
Hall 17, Stand C1-1 & C1-2
Ryobi’s PQS will be demonstrated, which the company says provides a new way to monitor ink density during the print run, using a CCD camera mounted in the delivery section to take a digital image to measure the density of the colour bar on the printed sheet. Any correction values needed to match target densities are calculated and fed back into the system. Ryobi PQS is also able to detect print defects, alerting the operator to problems and tabbing the necessary sheets in the delivery stack for easy identification.

Presstek
Hall 4, Stand B3
The company will highlight a new quality control and print inspection system on the 75DI. This added function ensures there are no issues during the run that cause excessive waste or re-runs due to quality issues. The inspection system not only reads the colour bar on each sheet, adjusting colour on the fly, but also checks each sheet for print defects, providing feedback to the controller and ensuring consistently high quality from one sheet to the next and from job to job.
