UV curing enables reliable, faster and more consistent production of security printing with special inks.
In this application the purpose of the machine is to coat the letters and numbers of a licence plate with one colour. This is done in 3 layers: 2 layers of coloured ink and a clear top coat.
The ink supply is automated from the can into the roller coater.
The plates are pre-heated by IR and then pass under three roller coaters. After each roller coater is a flash-off zone and a UV-lamp.
The UV-lamps used are GEW’s model VCP with a maximum power of 200W/cm.
