A film label comprising a film layer with printed material on the front or back surface, where the back surface may be covered with an overprint coating. The overprint coating protects any reverse-printed material, and may be colored or patterned, or both. One exemplary pattern is achieved by alternating coating weights to create a series of lands (i.e., raised areas) and groove (i.e., lower areas). The grooves help move entrapped air and gasses from the back side of the label, and may help water in a water-based adhesive wick away. The pattern can be a series of sinusoidal waves, curves, straight lines, or a variety of other patterns. The coating may also be used on opaque labels to assist in drying the label adhesive.
