Jvanick is correct. Check out the attached pic to see the difference.
Understand though -- opacity in plastisol is primarily gained through STRONG pigment loading. That is white, yellow, blue-shade green, etc. Increasing the level of highly saturated pigments - clean, but weak - like reflex blue (marine) or flou's really do not increase opacity. So in this example, the white percentage is still less than 1% of the total (although darn near tripled from original).
Wilflex ready for use Super Flou's are built differently at the plant. They do not use the standard Epic Mixing Base, but rather a base that is special to their flou formulations. This base is not available for sale - if I recall, it can only be processed on the specialized equipment at the factory.
