approved artwork, ensuring that every product meets quality standards. The new system’s flexibil- ity and precision were particularly beneficial, given the complexity and variety of Winpak’s packaging solutions. This has revolutionised the way Winpak operates
– cutting inspection times and costs and raising product quality. It also improved Winpak’s opera- tional dynamics, customer relations and sustainabil- ity measures.
“It saved us thousands of dollars,” said Jim
Imburgia, director of innovation at Winpak. “We cut our deliveries in half.”

When it came to specifying a corona treatment supplier for FlexPak’s new laminator, Vetaphone was the preferred choice. The company now has three of its treaters onsite – two on the laminator and one on a blown film extruder. Used mainly for laminating 12-micron PET to 7-micron aluminium foil, FlexPak runs the line at 250m/min on predomi- nantly 600mm wide webs, although the Vetaphone system is actually a 1.3m VE1C-D 1420 treater with six ceramic electrodes with an iCorona 2UL 8kW generator. “Vetaphone treaters are easy to maintain,” he
added. “The way the electrode cartridge slides out and back in gives the operator easy access for cleaning – which we can do offline if we want to. It has better electrodes, heat transfer and cooling and has reduced our overall costs.”
Print inspection Canadian packaging specialist Winpak has used an inspection system from Baldwin to check the quality of its printed packaging. Winpak’s expertise spans flexible and rigid
packaging, lidding and machinery. Recently, the company recognised the intricate nature of packag- ing printing, especially when handling dense information for product labelling. A big challenge it confronted was that traditional manual inspection processes were time-consuming, prone to errors and increasingly untenable in a competitive market that demanded both perfection and affordability. This challenge was not unique to Winpak and is a common stumbling block in the packaging industry – where the margin for error is nil, and there is huge pressure to deliver flawlessly. Winpak invested in Baldwin’s Guardian OLP
offline proofing and inspection system, and its Guardian PQV 100% inspection system. This combination has helped it to conduct thorough inspections, whether comparing file-to-file before press runs or analysing press samples against

Inline inspection Isra Vision will present a number of inline inspec- tion solutions for printing and packaging at the Drupa event in Germany. The latest version of PrintStar Evo, its system for inspecting web material for flexible packaging, includes a new ‘static code reading’ function – mak- ing it possible to check the legibility of barcodes and QR codes. It reads the code and tells the operator whether it is legible – allowing appropri- ate action to be taken. Enhanced camera technology ensures better detection of typical printing errors such as splashes and spots, missing ink, register errors, streaks and drags as well as dirt. It still includes its ‘MultiView’ functions in which multiple camera banks simulta- neously carry out further inspection. This enables the detection of initially invisible production defects such as hazing, plus decorative varnish defects or cold sealing defects. Another highlight is DualStar, which can inspect unprinted web materials, such as films, as well as printed materials. This is of particular interest to the converting sector, which needs a single inspection system on machines such as laminators, rewinders or slitters. Thanks to 100% inline inspection, DualStar can boost quality and reduce costs. In addition, Epromi is a production management intelligence tool. It enables real-time monitoring of processes and inspection systems and in-depth analysis of the recorded production and inspection data.
