Digital printing techniques are too different in terms of their characteristics (e.g. surface tension). For this reason, TroFilms GmbH, a medium-sized and globally operating specialist for high-quality special lamination films for the graphics and industrial lamination industry, located in Georgensgmünd in central Franconia, Germany, together with project manager Torsten Uhlig from Torsten Uhlig Solutions, Porta Westfalica, Germany, have initiated a comprehensive study to be able to make concrete statements on which film types are best suited for which digital printing process.

For this purpose, print samples were created in five distinct digital printing techniques on the basis of a coloured test forme with different surface coverings, which were then laminated with six selected thermal foils.

The film types were three qualities from the TroProtect series (scratch-resistant matt films) and three qualities from the TroTemptation series (scratch-resistant soft matt film), all from TroFilms.

The printed sheets laminated in this way were then analysed using various laboratory test series. All the sheets were then tested under the same conditions using folding tests, embossing tests and tests to determine the compound adhesion.

One and the same paper was used, namely the substrate LuxoArt 150 g/m2 from Papyrus.

The sheets were printed in the processes:

  • Dry toner: Here the toner particles are transferred from the photoconductor drum to the substrate and lie "loose" on the substrate. Only through the fusing roller (heat) are they fused with the substrate. The toner particles have a size of D50 = 8 μm. From 5 - 13 μm particle size can therefore be called relatively large particles.
  • Liquid toner: Here the toner particles are first dispersed in liquid. They are transferred indirectly to the substrate via a blanket cylinder ("offset printing" principle). Otherwise... [Click Here]
 

Covid-19 - Designer publishes production data for disposable face masks

In order to counteract the current supply bottleneck in face masks for the population, designer Alexander Dort has developed a simple face mask that can be produced in large quantities very quickly by packaging printers, converters or owners of a cutting plotter.

The demand for face masks is currently enormous due to the worldwide COVID-19 pandemic. However, the availability of such masks is limited. As a result, masks are now often produced manually by workshops, tailors and volunteer workers. However, the production capacities and speeds for this are very limited. On the other hand, many industrial production systems in the packaging industry are currently at halt due to the pandemic. This gave packaging designer Alexander Dort the idea to use the enormous production capacities of the worldwide printing and packaging industry to produce simple face masks in large quantities. He designed this in such a way that theoretically every printing company and every converter that has a simple die-cutter in 3B format or also owners of cutting plotters can produce such masks from folding carton or film. In the simplest case, printing is not even necess... [read more]

Wagner Prestige Labels reduces waste and ramps up capacity with Durst Tau 330 RSC E investment

Brixen, Italy / Sydney, Australia – 30.03.2020 – Durst, manufacturer of advanced digital printing and production technologies, has solved waste and digital capacity issues for family business Wagner Prestige Labels with the installation of a Tau 330 RSC E inkjet label production press.

Wagner’s choice of Durst’s RSC technology was driven by speed, quality and environmental considerations. “We decided to ramp up digital color capacity to the highest we could, and the Durst Tau 330 RSC E came up trumps,” said John Galea, Managing Director of Wagner Prestige Labels, of Wetherill Park, Sydney, Australia. “In only six months it has really proved itself, to the point that digital is now between 30 and 35% of our business. The quality of the labels is right up there with flexo and letterpress.

“Another important benefit is that waste is greatly reduced, with the threaded meterage on the Durst  Tau 330 RSC E even being able to be drawn back and printed. Waste is a big issue for label printers, especially with multiple versions, so anything we can do to reduce it is good for the environment.”

The Durst Tau 33... [read more]

DSM expands textured coating resin range with highly functional sandy-feel resin

Royal DSM, a global science-based company in Nutrition, Health and Sustainable Living, today announced the release of Skins® Sandy, the newest addition to its Skins® range of haptic coating resins. Like the other Skins® resins, Sandy will enable brand owners and convertors to differentiate their products by adding an extra layer of sensory experience. Specifically, the new resin will enable print and packaging manufacturers to add sand-like textures to a wide range of materials, including food packaging.

Tactile elements in print and packaging are increasingly used to differentiate brands, by providing a sensory experience that reflects their products. DSM’s Skins® coating resins range aims to meet this need by enabling different textures in a range of print and packaging materials. Skins® Sandy will offer sandy-feel textures ranging from fine to coarse and is particularly suitable for overprint varnishes, paper & board, and flexible packaging. In particular, its broad food contact compliance will open new possibilities for textured food packaging. It will be compatible with a wide range of printing processes, including flexographic and gravure.

Skins® Sandy will make it easier for coating formulators and converters to deliver sandy textures. Unlike many sandy-feel coating resins on the market, Skins® Sandy delivers the desired sandpaper texture in ... [read more]
