Crystallina is made of an iridescent translucent mylar flake that is suspended in a clear plastisol ink base. The clear base has a much lower loading of flakes so there is a greater amount of clear base. This allows the under color to show through when this ink is overprinted. Because of the nature of the flake, it gives the overprinted color a shinny, sparkly, rich look. Crystallina is very similar to glitter.
