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.
The UV system BLK®-6 was developed 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 and production safety with reduced operating costs.
