The BLK®-6 is a newly developed UV drying system designed for web-fed printing. When compared to conventional UV systems, remarkable progress has been made in drying performance of the BLK®-6 without having to increase the UV lamp output. This means greater productivity with reduced operating costs.
The intelligent IPS control system governs all functions and components of the UV system. BLK®-6 UV systems are equipped, as a standard, with a UV online sensor. This has made it possible for the first time to measure the UV radiated power of a UV system online. Compared to conventional UV systems, the process reliability has been increased considerably with this new feature.
The BLK®-6 boasts of extremely high efficiency. Instead of the previous three BLK®-2 type units with 200 W/cm, the same excellent drying results can now be achieved with just two of our new BLK®-6 units with 180 W/cm. Operating costs have been considerably reduced thanks to the significant reduction in energy consumption.
In comparison to thermal drying, UV technology offers economical and technical advantages for newspaper printing, especially in the area of small and mid-sized print runs: Through the low heat input on the paper web there’s no corrugation in UV printing, as well as no fan-out effects. The instantaneous curing of inks prevents the set-off of ink on idle rollers, folders, transportation belts and mailroom equipment. UV systems are compact in size and are associated with significantly lower investment costs than heatset dryers.
