Since DigiPrime® 4462 is an offline primer, we recommend Flexo or Reverse gravure when applying the primer on the substrate. Wet coat weight to apply may vary, but is typically between 0.9 to 1.3 GSM wet. Refresh with corona discharge may be beneficial for synthetic films. Though coat weight is low, special care should be taken when drying the wet primer film (drying conditions) as well as rewinding and storing the primed reels prior to printing.
