Following a major trend in the industry, Labelexpo Europe in its 40th year included a significant panoply of presses and ancillary equipment suitable for flexible packaging, even though substrates and other consumables for this segment were missing entirely at the show. (There were some film suppliers but they came to Labelexpo mainly to project their films for use as face stocks in pressure-sensitive materials and to some extent for use in wraparound labels, IML and shrink packaging.)
Increasingly, label converters have been compelled to diversify into packaging, to offer their customers a combination of pressure-sensitive label stock, wraparound labels, IML, lids, custom mailing tubes, shrink sleeves, standup pouches, rolls of single- or multiple-layer flexible packaging, or folding carton boxes. And technology developments have been an enabling factor in this trend, as narrow- and mid-web presses and their converting and finishing extensions are converging on all levels. This has also made label production more accessible for companies who started as flexible packaging converters, and even for those whose core business is in commercial offset.
Labelexpo’s flagship trade fair has been able to keep exhibitor and visitor numbers fairly stable, even though both were slightly down this year. Almost a quarter of the 600 exhibitors were companies from Asia, including 85 from China, 20 from India, 16 from Japan, 12 each from Taiwan and Korea, and one from Malaysia, not counting the representatives at the stands of the European and American brands.
Many of these told us that they came to Brussels to target the Eastern European, Russian, African and Middle Eastern markets, rather than the industry’s largely saturated client base in Western Europe. Next to the flexo, offset and hybrid presses running at the stands of the large international brands but also at some of the Indian, Chinese, Turkish and other manufacturers’ booths, there were about 50 inkjet presses from 30 manufacturers at the show, as well as inkjet modules and print bars from more than 15 manufacturers.
Five misconceptions on the latest generation of label presses
- ‘The future is digital’ – Obviously, digital printing is replacing the other printing technologies in many areas. However, there are as many applications where digital will remain one mature set of technologies among other ones, side-by-side and in combination with flexo, offset, gravure, screen, intaglio and various embellishing techniques, which each have their specific characteristics and advantages in terms of quality, feel, productivity and economics. These are unlikely to disappear in the foreseeable future, and the Labelexpo organizers are quite right in observing the current “flexo fightback.” Opposing digital and analog as a sign of progress is a marketing bubble, that we can only hope will soon be something of the past.
- Hybrid presses – In the label industry, most of the larger narrow-web presses have a long history of integrating modules that combine the main flexo or offset units with rotary screen, gravure, and other technologies. They have now been complemented by inkjet modules and industrial engines based on inkjet or toner. Presses based entirely on digital units are being complimented, for instance, by flexo units for coating, varnishing or white inks. Same story for converting equipment. So, what’s new, and what is real? As virtually all presses use ‘hybrid’ technologies in one way or another, the ‘hybrid’ buzz word should soon be redundant as well. Without questioning at all the fabulous capabilities of these presses.
- In-line converting – Narrow- and mid-web presses have been at the forefront of integrating converting functionalities into printing presses. Diecutting and foiling are typical examples. Bobst’s Lemanic is an example of a press almost fully integrated into the final product processing line, where cigarette boxes can be printed, coated, embossed, die-cut, inspected, and directly conveyed into the cigarette packaging line. But again, there is no one-for-all solution, and many applications, for reasons of speed, quality, operator expertise or simple economics, require off-line converting and finishing. That’s why, also at Labelexpo, so many converting and finishing devices can be found, overtaking the number of presses there.
- On-press switching between labels and packaging – The claim of easy switching between label and packaging products on the same press hardly corresponds to market requirements. There is a clear trend of label converters venturing into folding carton or flexible packaging, and packaging converters adding adhesive labels, tubes, and pouches to their portfolio. For converters, the ability to offer both adhesive and wrap-around labels, or for commercial printers to add roll-to-roll to sheetfed label and packaging products, is a logical step, facilitated by more and more accessible technology developments.However, in most cases, they will dedicate their presses to specific job categories, and not switch between labels and packaging on the same machine! Typically, a converter working with a particular type of presses will buy another type of press to expand in a new type of business but will dedicate each press to either labels or pouches or shrink sleeves or flexible packaging, each based on their settings, technical requirements, and economics.
- Industry 4.0 readiness – Most press manufacturers claim to be ‘Industry 4.0 ready,’ but does this make much sense for a printing press? Artificial intelligence and robots may be useful at the interface between printing and finishing, and between finishing and processing, but for the actual printing process, they have no meaning. Color management and inspection systems may have some built-in autocorrection capabilities, but they will never tell me at which press speed and at which solvent concentration a particular color will reach its optimal hue.Robots may be used to load and unload the substrate, but at what cost?The only application of Industry 4.0 readiness that has any relevance is the interaction with customers’ packaging and processing workflows, such as linerless labels or IML that can be picked up and applied by a robot arm in the packaging process. Again, much marketing buzz in an industry which in reality is much more down-to-earth.
