Short-wave high-performance drying
The NIR system technology offers optimal drying and curing solutions for virtually all types of coating. This applies to substrates both in sheet form and on a continuous web, including paper, cardboard, foil, textiles and sheet metal.
The technology developed by Adphos Digital Printing, located in Bruckmühl, Germany, is based on a special short-wave near-infrared (NIR) energy source. This energy source ensures a high degree of transparency, especially with thin papers and plastics. It can be focussed on the printed or coated sample and enables optimal and integrated air ventilation. This means the water or solvent vapour can be drawn off and expelled effectively.
This special drying technology is intended for use with a wide variety of high-performance coatings and therefore fills a current gap. It can be used at production speeds of up to 1,000 m/minute and is suitable for substrate temperatures below 80°C. Even working temperatures below 50°C are possible, such as would occur with thermal paper for example.
Coating consumption can be reduced by up to 50 percent and the dryer power consumption by as much as 70 percent. Furthermore, the NIR technology is characterised by the fact that open substrates are only slightly penetrated.
At drupa, on Stand A30 in Hall 5, Adphos will be demonstrating the dryer system live in inkjet printing on high-gloss paper or plastic cards, in printed electronics and with coating and high-performance design options.
