*A Must to prevent your ink from smearing

Rub a small amount of Micro Glaze on the front and back for your printed photo or artwork to protect it. Quite often if you use an Ink Jet or Bubble Jet printer to print your photo and then use one of these products (resin, epoxy, diamond glaze or glossy accents.) your ink will smear. Micro Glaze prevents this from happening.
