I have been asked by one of my customers if it is possible to convert their press to LED UV instead of conventional UV lamps. Has anyone used the new LED UV systems and how does it compare to the conventional UV systems? What are the pro's and con's? I have done some research and this is what I have come up with; Conventional UV; High power consumption High heat output Wider range of UV light 200 - 400nm wavelength High press speeds Requires external cooling, air or water. Lamp life about 1000 hours Wide range of ink's, varnish's and coating's Creates ozone Hazardous light output, must be shielded Must protect wiring, seals etc. LED UV: Less power consumption Less heat output Narrow wavelength 395 nm +/- 5% Press speeds - unknown No external cooling required Lamp life 20000 -50000 hours Limited ink's, varnish and coating's No ozone Less hazardous light output Is conventional UV more forgiving than LED UV? How much of a cost savings is there to the LED UV system if you have to purchase specialized inks for the LED UV costing as much as 20% more than conventional inks? Which do you like better, conventional UV or LED UV?
