QuadTech heads for China Print

QuadTech will highlight its portfolio of press control technology for the commercial web-offset, packaging and newspaper printing sectors.at China Print 2013, taking place in Beijing, from May 14-18 May.

Randy Freeman, vice president and general manager of Packaging at QuadTech, says, “We are very excited to be taking part in China Print, as it is the major print exhibition for a region in which the prospects for growth are strong. In particular, the continued fast-pace growth of Chinese consumer purchasing power is benefiting the packaging converting industry.

“There has been a lot of investment in packaging and converting equipment that can deliver more complex packaging and label designs, and major brand owners seek an identical look for their products globally. As a result, print suppliers must deliver identical results throughout the print run and from one print run to the next. Therefore, QuadTech has developed solutions for on-the-fly spectral colour measurement, register control and inspection on a range of substrates, removing manual input of the print quality control process.”

Quadtech says that, for packaging printers, the new Color Quality Solution simplifies colour preparation in packaging printing. This provides a standard spectral color measurement throughout the ink dispensing and printing stages. It includes in-line spectral data obtained from QuadTech’s SpectralCam, ink formulation data from X-Rite and ink dispensing technology from huber group or other ink dispensing system suppliers.

Also for the package printer, QuadTech says its Color Measurement System with SpectralCam HD enables continuous, in-line monitoring of virtually all web-fed package materials with QuadTech’s patent-pending web stabiliser technology. It captures images at 2500dpi, allowing defects to be pinpointed and remedied without production stoppages. The company says the QuadTech Inspection System inspects the entire substrate width 100 per cent of the time throughout the entire press run with the Golden Template Comparison. Every printed copy is compared to the Golden Template, which is a chosen printed copy as close to the original artwork as possible, resulting in a fixed and repeatable quality standard.

The company continues that its Color Control System with Instrument Flight and SpectralCam ensures uniform colour over the entire print run, including the delicate gray and overprints. Its spectral-based sensor gathers colorimetric and densitometric data across a fast-moving web from a continuous colour bar. This data is used to calculate to Lab and densitometric values and then analysed by System Brunner’s enhanced Instrument Flight plus Lab for accuracy in colour control and gray balance.

QuadTech has added its Digital Ink System to the portfolio for web offset printers as well as its color, register and inspection controls. The system replaces conventional ink fountains with computer-controlled ink injectors. This ensures the precise volume of ink required in each control zone is consistently present, at all press speeds, resulting in accurate density control across the printed image.

Also for the newspaper portfolio, QuadTech has added automated, on-the-fly water control management to the Color Control and Web Inspection System with AccuCam. This automatically adjusts ink and water levels at full press speed to reduce the occurrence of common newspaper printing problems such as scumming (catch up), creasing, transposed plates, plate crack-outs, and tramlines.
