Ink curing 
Mains voltage variation causes problems with the curing of inks used by today’s generation of digital printers. These large UV light cured printers are susceptible to low mains voltage which can cause the lamps to not be at their correct output.
The result is the ink is not dried properly, leading to smudging. Leading manufacturers now recommend or specify Claude Lyons series TS Voltage Stabilisers which have provided a complete solution. .
