A Cost Efficient, Global Solution for Flexographic UV Printing

In a first part, this paper analyses technical and economical advantages and drawbacks of standard
flexographic printing practices using thermal drying of ink solvents or UV-curing of solventless inks technologies. In a second part, it proposes a technically efficient and cost effective global solution for flexographic printing implying an advanced gas phase ultra-thin primer coating of the filmic substrates fully suitable for printing with UV curable inks and a specifically designed Gas Seal Kit around the UV lamps which allows improved polymerisation of inks under variable oxygen concentrations in the reaction zone.
