Coating show promises innovations as companies begin to re-invest
GERMANY
Split second curing process has been developed
A
T THE upcoming European Coatings Show Hönle will present its solutions and systems for applications in the curing and drying process of UV reactive coatings and varnishes. Hönle has developed curing systems for coating, finishing and varnishing of web-like substrates and 3D objects. The curing process occurs in a split second and provides excellent printing results as well as high quality and robust surface finishing of various materials. This UV technology with its additional developments has been finding its way into various industries in increasing volume; particularly high quality coatings that are usually cured with inert technology. In the inert process, the oxygen (O2) in the irradiated area is displaced by an inert gas (usually nitrogen). With inert UV curing, a significantly lower proportion of photo initiator within the UV ink and varnish is required. Inert UV curing increases printing efficiency and saves energy, because less lamp power is required than in an oxygenated atmosphere. This is also an advantage for printing on temperature-sensitive substrates. At the European Coatings Show Hönle will display an inerted UV curing system for the finishing of films and prints.
Hönle: Inert UV
ideal for curing temperature sensitive substrates. The high radiation intensity leads to substantial improvements when curing colours, varnishes, coatings, adhesives and sealants.
In addition to its UV curing systems Hönle will exhibit its curing chamber, the UVACube 2000, along with its approved UV measuring systems; UV Meter and UV Scan. The UV Scan was developed together with tesa and allows a simple and reliable analysis of the UV dose in the production process.
With a maximum power of 34kW, the power output of the EPS gives a 10 percent higher UV yield for the equivalent conventional transformer. The use of a Hönle EPS together with high-quality lamps and optimized reflector geometry leads to higher efficiency at a lower energy consumption.

Twin coater to be installed next month
P
RINT COMPANY Offset Druk from Rzeszow, Poland recently placed an order with KBA for a six-colour Rapida 106 in a twin- coater configuration. The press is to be installed in April and will lend a significant boost to the production capacity currently offered by two half-format presses from another manufacturer. At the same time, the Rapida 106 will enable the company to tackle new and creative finishing solutions.
UV-LED is another important further development of UV technology. At the European Coatings Show 2011 Hönle will show its LED power line. This is a high-speed array for a pinning and curing process with printing applications as well as for the curing of adhesives and sealants. The curing of coatings and varnishes with UV-LED is still a future technology. Nevertheless the commodity and coating compound manufacturers are developing more and more products to react to market requirements.
PureUV
Another high-performance dryer is the Hönle-developed PureUV. This design prevents direct irradiation onto the substrate. The unwanted infrared energy is carefully filtered out by the patented reflector geometry. The result is highly effective irradiation with a low temperature emission –

Offset Druk has plans for expansion into the packaging sector, coupled with the opportunities to offer new finishing technologies. However, Proprietor Adam Motyka needed to invest in a high-performance medium format press. The chosen Rapida press boasts a host of technical features that are still far from commonplace among users in Poland. Adam Motyka says: “From the technical point of view, this is the most up-to-date press on the market in its class, in my opinion, and offers us techniques that are only available in this form from KBA. Our decision to invest in this technology will enable us to bring its potential to the Polish market and to satisfy the demand for high-quality packaging.” The Rapida 106 is to be installed in a new production hall at Offset Druk. It is engineered for production speeds up to 18,000 sph, and can handle substrates from 0.06 to 1.2mm thickness thanks to the integration of dedicated board handling equipment. The preparations for packaging applications also include raising the press on a 450mm plinth. The long list of high-tech features includes the side lay-free infeed DriveTronic SIS, DriveTronic SPC for simultaneous plate changing, register-true plate mounting with Plate Ident, automatic washing systems for the inking units, plate cylinders and blankets, a fully automatic coating supply and cleaning system for the coating towers, ErgoTronic ACR for automatic register corrections, automatic suction ring positioning, automatic non-stop pile changing at the delivery, DensiTronic professional and QualiTronic professional for sheet inspection and inline density control, as a basis for the highest levels of productivity to be experienced in this format class.
