Bands were discussed in the last column and Ranges are discussed in this one. Together, these topics account for a large portion of EIT’s customer “education” efforts. Consistent UV measurements start with a radiometer with the correct band and range for your application. Are we talking the same language in the context of UV curing? Dynamic Exposure: continuously moving or … [Read more...] about Home Hone on the Range

Understanding Glass Transition Temperature: Part 3
In the last two installments of Professor’s Corner, the concept of the glass transition temperature (Tg) was introduced and discussed.1, 2 That discussion continues as we look at the structural and compositional factors that influence the Tg – factors such as polymer backbone rigidity, morphology, cross-link density and pendant side-group length, shape and polarity. Since the … [Read more...] about Understanding Glass Transition Temperature: Part 3
What Can You Do with Electron Beam?
Food packaging and flooring, shrink-wrap and sterilization, cold seal adhesives and so much more – electron beam (EB) is a versatile technology used in a multitude of applications with potential yet untapped.1-3 The key reason for this versatility is electron beam’s ability to break chemical bonds without the assistance of an initiator and under ambient conditions. While EB is … [Read more...] about What Can You Do with Electron Beam?
Food Packaging-Compliant Inks and Set-Off Migration
By Julie Cross and Marina Santos, Domino Printing Sciences Abstract The challenges associated with migration when working with low-viscosity inkjet systems for food packaging applications are well understood in the industry. We will discuss the terms “low migration” and “food packaging-compliant” and then will review a migration study completed with a food packaging-compliant … [Read more...] about Food Packaging-Compliant Inks and Set-Off Migration
