A viewer from Kansas asks:
"Are there air pollution concerns from the use UV printing inks?
What are they?
How does one measure pollutant output?"

greatly reduce VOC emissions.
A good source of technical
information on UV and electron-beam cured inks is RadTech
International. Radtech's Web site is at
I assume the question re. pollutant output refers to the process used to
calculate emissions. Typically, each state has procedures that must be
used to estimate emissions for purposes of determining the need for a
permit and for annual reporting. Recommended contacts in Kansas include:
