ABSTRACT:
A process for enrobing a core, such as a tablet core, uses a coating that is made of a patterned film having portions that are visually distinct (e.g, differently colored) from one another and having a transition line segment between these visually distinct portions. At least a portion of an outer surface of the core is covered with the film, such that the transition line segment forms a substantially continuous transition line on the coating and such that a film seam is formed which is different from the transition line. Alternatively, the coating is formed from two such patterned films, in which case the outer surface of the core is covered with the two films such that the two transition line segments cooperate to form a substantially continuous transition line on the coating and a film seam is formed which is different from the transition line. Prior to covering the outer surface of the core, the two films may be oriented such that the resulting enrobed core has a bi-colored coating with two visually distinct portions each lying on opposite sides of the transition line of the coating. The two films may also be oriented such that the resulting enrobed core has four alternately arranged colored portions, two of which are of a first color and the other two of which are of a second color, thereby resulting in a “checkerboard” effect.
