Ink-Substrate Interactions...

So the question becomes, how to optimize ink-substrate performance during printing while meeting all customer requirements for the end use of a product. For example, Barton explains, there are food-level inks that have to be edible if they come in contact with the product to prevent toxins from leaching into the food. By the same token, he says, inks and materials used to create a box of fish sticks or the label on a bottle of wine destined for the ice bucket will have different requirements than those used to create a cereal box, based on color-fastness and moisture-resistance.
