Adhesion
A basic requirement of any ink is that it adheres to the substrate upon which it is printed. With paper and board, this is really a problem. With non-absorbent substrates such as plastics and foils, it can be. Three very simple test methods have been established which give a very good assessment of ink adhesion- fingernail scratching, scotch tape test and wrinkling. The **fingernail test** is a very useful technique for foils, films and plastic, including polythene bottles and sheet plastics. The ink film is scratched with the nail and the ease or difficulty with which the ink is removed is a measure of the adhesion or the hardness of the ink film.
