Abstract:

UV-cured inks are one of the fastest growing segments in the printing ink industry today. They have gained acceptance for use in lithographic and flexographic printing, as well as screen-printing. The use of carbon black in UV cured ink presents some interesting challenges:

  • Since carbon black absorbs UV radiation, it interferes with the cross-linking of the resin system in UV inks, thus requiring the addition of more photo initiators or higher energy for cure.
  • Black UV inks tend to build viscosity upon storage, in some cases even to the point of premature curing in the ink container.
  • MOGUL E, a powdered carbon black, and BLACK PEARLS E, a pelleted carbon black, are specifically designed to meet the demanding challenges of UV inks.
  • Cure energy, viscosity stability, color characteristics and dispersion are explained in detail in the attached brochure (pdf).
