Energy cured inks and coatings have been used for many years to print food packages but because the technology is still perceived as new and chemically complicated, it has been the burden of the formulator to fully prove its suitability for the end product. Much work has been carried out to ensure the efficient curing of the system but many times trace impurities or residuals have caused the product to fail. The problem of impurities is not unique to energy cured systems but the high degree of testing required has always made us aware of these impurities, which can also exist in conventionally dried systems. With today's increased environmental awareness, new or pending legislation and improved analytical techniques, it becomes the requirement of the ink formulator to fully know his raw materials and the process of conversion.
