How do I Use a Radiometer to Check UV Cure?

When setting or checking for proper performance of UV equipment, wattage and belt speeds are only a reference point and can not be used in determining actual energy being produced. A radiometer should be used to obtain and document accurate readings for the purpose of lamp maintenance and settings for proper ink performances.
All equipment is NOT equal and will not always produce the same energy even when the same parameters are set. Degradation of lamps and reflectors will also have a tremendous effect on energy levels achieved. Therefore, reference only to wattage and belt speed could be misleading and actual reading of energy, in millijoules, must also be monitored. This can only be accomplished with the use of a radiometer. So if you own UV curing equipment, then you should also own a radiometer.
