White ink formulation is made particularly difficult as a high pigmentation level is needed to ensure a white ink has sufficiently high opacity. Furthermore, this has to be achieved while maintaining all other ink properties including: viscosity, surface tension, particle size, cure speed, adhesion range, flexibility, jetting reliability and drop formation / break-off.

We developed several WHITE formulation targetting different substates:

  • outstanding over-printability
  • jetting reliability
  • high opacity
  • available as rigid or flexible
  • excellent adhesion to difficult substrates
