The exhibitors at InPrint

Ahead of the Inprint show itself, taking place on November 14-16, 2017, at the Munich Trade Fair Centre in Germany, some of the 145 exhibitors have revealed their plans for the show.

GEW’s release of ultra-wide UV video (Hall A6, Stand 455)

GEW has released a new video to illustrate how wide-web converters can benefit from GEW’s fully air-cooled NUVA2 UV systems. The NUVA2 lamphead is available in widths of up to 2.50m and boasts particularly fast switch-on and cool-down cycles achieving considerable electricity and time savings. It addresses the specific requirements of converters who need to coat substrates in extreme widths.

Likora in Germany upgraded the final varnishing station on one of its gravure printing lines with the new UV-curing system replacing an older system. To this purpose the company integrated three GEW-made 240cm-wide NUVA2 UV lampheads with Rhino power supply. The three UV lampheads are positioned vertically one after the other to achieve the maximum UV-curing effect. The UV system is mounted in a custom designed aluminium frame that integrates a retractable cooling panel and water-cooled quartz window to prevent the heat transfer onto the substrate.

The configuration is now able to print and varnish substrates up to 2350mm wide with speeds up to 120m/min and mainly produces finish foils intended for wrapping and laminating on wood-based materials.

Polar UV infrared reductions in UV curing systems (Hall A6 Stand 228)

The POLAR-UV Bridge reflectors are provided with special mirrors that fully reflect the UV-radiation but absorb infrared radiation. Thereby, the infrared radiation is directed into the reflector body. Due to cooling air or cooling water (optional), the reflector body is now so cooled that the thermal energy is removed and the reflector itself emits no heat radiation.

In conjunction with UV-BULB Design and the optional Heat-EX system, this results in the optimal reduction of direct IR radiation or indirect heat conduction to the substrate. As a result, material distortion, material damage and crack avoidance can be achieved to a considerable extent, with, at the same time, enormously high UV doses of 3000mJ per cm².

Inkjet technology on the runway (Hall A6 Stand 428)

Fujifilm has extended its full cooperation for the production of dresses by Yuima Nakazato, the first official Japanese guest designer to take part in the Paris Haute Couture Collection since Hanae Mori 12 years ago. Fujifilm Inkjet Technology made a contribution to the production of the outfits that shine with a bright yet mysterious aurora-like light. The dresses were heavily featured in international fashion magazines, winning a favourable reception.

In 2009, Yuima Nakazato launched the brand Yuima Nakazato and has since then continued to show creations that make skilful use of hologram light effects. This most recent creation looks as if small countless coloured folded paper cranes have flocked together, responding to the surrounding light by emitting their own shimmering colours. These creations are built from shaped cells (units) and use holographic material, which was completed through six years of research with a hologram manufacturer. Images are printed on the material using Fujifilm’s Acuity Select 20 wide-format UV inkjet printer, together with the company’s high-elongation Uvijet KV ink.

To create a single unit, an A5-sized piece of printed material is finely cut using a cutting plotter. Each individual unit is carefully folded into shape, just like origami. More than 1000 of these units, folded by approximately 100 staff, are combined and assembled to match the model’s figure. In this way, without using a loom, fabric, or any stitching, a single Yuima Nakazato dress is created.

The new liquid diaphragm pump series from Gardner Denver (Hall A6 Stand 744)

Gardner Denver will present pump solutions targeted at manufacturers of industrial inkjet printers such as its liquid diaphragm pump series 6410 and 6311 Thomas. Both pumps stand out for their uniform volume flow and compatibility with chemically aggressive media, enabling them to run uninterrupted for longer periods with print quality and high printing speeds. Manufacturers of large format, label, textile, marking and coding or even ceramic tile printers can adapt the diaphragm pumps to specific needs, as the pumps support inks with different viscosities and particles, additive and solvent proportions and types.

The diaphragm pump 6410 is designed for the even transfer of inks in the range of 600ml/min. It transfers inks free of bubbles with minimal pressure pulses. The pump is particularly robust and resistant to chemically aggressive media. The platform 6410 is also available with one or two heads, which ensures manufacturers maximum flexibility when designing their products. Depending on client requirements, there are pump components in various materials such as EPDM, PTFE or FFKM.

The diaphragm pump 6311, on the other hand, was developed for flow rates in the range of 200ml/min and pressures up to four bar. Its liquid throughput can be controlled in a linear way and even at higher pressures the pump offers excellent reliability and durability. The diaphragm pump 6311 is also compatible with chemically aggressive printing agents and enables tailored solutions depending on the client’s requirements.

Both new platforms extend the wide range of liquid diaphragm pumps offered by Thomas by Gardner Denver. Above all, they are targeted to manufacturers of digital inkjet printing systems and support both continuous inkjet (CIJ) and the drop-on-demand (DOD) principle. CIJ printers are used primarily for labelling or coding surfaces such as bottles, cans, cables or food packaging. DOD inkjet printers are used for applications such as large format, textile and label printing, but also printing on wood and ceramics.
