When There's No Cure

According to Midlik, one of the largest markets for UV flexo printing is flexible packaging—especially printing on film substrates. "We tell our flexo film converters to constantly measure dyne levels. UV flexo inks require that the dyne level of the film measure 44 at a minimum. We also recommend that converters install a corona, or a flame treater in-line, to ensure that dyne levels match the required levels."
