Case study – Steurs’ 360-degree approach broadens flexo

Steurs’ R&D leads to S-Dot innovation

Steurs flexo prepress bureau

Steurs’ Graphic Solutions, a flexo prepress provider can look back a long way — 70 years, to 1949, when the two Steurs brothers started what has become one of Belgium’s leading packaging prepress houses. The backward look will be a short one because all eyes at the Antwerp-based business are firmly fixed on the present and the future — ‘on continuing to create solutions for today and tomorrow,’ as the company’s tagline has it.

Those solutions have to do a lot in today’s packaging market, says general manager Dirk Cantens. “We work across all three processes — gravure, offset and flexo — and the full spectrum of packaging materials: metal, plastic, folding cartons, glass, and foil. Not only are we operating in a constantly changing sector, but one where every brand, printer, and converter has its own needs. Every environment is different.” He adds, however, that there are some challenges that all these players face. “To stand out, packaging has to make an impact. We call it ‘getting to the heart’ of the consumer. And the impact is a combination of things — color, image quality and, of course, creativity.”

R&D makes the difference in impact

Steurs offers its clients all three, positioning itself as a 360-degree service provider of prepress, premedia, and creative design. Since 2014 a further string to the Steurs bow has been the R&D department tasked with solutions development. Explains Cantens, “R&D is critical to our philosophy, which is that to be a serious prepress partner, you have to be able to innovate — to develop tailor-made solutions to customers’ challenges. The department works closely with our sales and production managers, and is almost always at the table when we’re talking to brands and converters. We believe we’re the only prepress supplier in our region that does this.”

So how does the approach work on a typical project? After the initial briefing, R&D creates a project plan to establish the steps needed to develop and implement the proposed solution: custom testing on the press, followed by in-depth analysis. Next, Steurs engineers the screening and or color management solutions — branded as S-dot and S-color respectively — needed to deliver the project and submits recommendations to the customer. After sign-off, the solutions are implemented into the workflow.

In-house creative and prepress broaden flexo’s appeal

S-dot was among the first products of Steurs’ R&D investment and illustrated the thinking behind the decision to set up the department. The initial objective, Cantens explains, was to broaden the appeal of flexo to brands and converters. “It’s accepted that flexo has advantages over offset and gravure — lower cost, greater flexibility as regards substrates, and shorter lead times — and these are all important to brands and their printers. But in the past, doubts about print quality and consistency outweighed them — things like lower densities and flexo edges.

“That changed when Flexcel NX arrived on the scene, and in the last decade, flexo has come on leaps and bounds. So we decided to make NX the platform for a new strategy to promote flexo as an alternative to the other processes, and made it a priority for R&D to develop solutions for high-quality flexo to increase its quality and stability.”

He describes S-dot as a group of screening technologies that Steurs applies to Flexcel NX to control ink transfer and dot gain either locally — in specific image areas — or across the plate. “This means we can print variable densities of the same color on the same plate, reproducing higher densities for solid colors while reducing dot gain in screened areas. There’s no edge on barcodes, and text is sharper. Whatever the substrate, we can guarantee these results. Today, more and more brands are convinced of flexo’s benefits, quality concerns have faded, and they’re willing to consider moving products across.”

“We simply show them”

Asked how Steurs makes a case for flexo to brands and converters, Cantens’ reply is concise, “We simply show them. We have an increasing number of successful projects in our portfolio, and these show what’s possible — the faster time-to-market, the lower costs, and so on.”

Steurs won a gold award at the inaugural Kodak Global Flexo Innovations Award

Steurs can also show prospective customers an expanding awards cabinet, home to a Benelux Packaging Innovation Award (for S-dot), and a gold award in 2018’s inaugural Kodak Global Flexo Innovation Awards. The entry, printed CMYK on high-shrink PET-G material, was a joint project between Steurs and printer Helios Packaging, with whom Steurs has worked since 2016. The relationship came about when Helios — predominantly a gravure producer of shrink sleeves — decided to focus 100% on flexo.

This radical change in strategy was driven by three new customer requirements: shorter lead-times, shorter runs, and greater cost-efficiency. “It was a bold decision by Helios,” says Cantens, “but one based on a clear understanding of how the market is changing, particularly the retail sector where most of Helios’ business is. It was made with eyes on the future.” Approaching Steurs was a natural next move, and the last three years have seen steady progress in testing and fine-tuning new S-dot technology, including extending its application to shrink-foil.

The result is a growing number of brands looking seriously at flexo as an alternative to gravure and offset. “We don’t need to sell aggressively,” says Cantens. “Usually, the samples speak for themselves, and all that the brands ask of us is that the flexo result is equal to, or better than, gravure and that the design doesn’t have to change.” He acknowledges that there remains a lingering perception that quality is an issue, but says it’s fading with every successful gravure-to-flexo conversion. “Each day, we’re proving the opposite.”

The impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South Asia is always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.
