ABSTRACT:
A method and apparatus are provided for applying swatches to a continuously traveling web, which is usually preprinted, and which is severed into sheets of a predetermined repeat length. When going from one size of repeat length to another size of repeat length, swatch-applying cylinders are profiled to match the cylinder velocity to the web velocity during a swatch application over a first portion of a revolution of the swatch cylinder and then the rotational velocity is changed substantially during a sync recovery portion of the cylinder's revolution. Preferably, the adhesive, which is applied to the web to adhere the swatches, is by an adhesive cylinder which is similarly provided with a matching velocity portion of a revolution and a sync recovery portion at a different velocity. The cutting operation is preferably by a knife cylinder which is also similarly profiled. Registration of the swatch to the web is achieved by sensing registration marks on the web and then by phasing the cylinders by shifting their angular position of the cylinder and the swatches thereon so that they are precisely placed on the web. In the preferred embodiment, color cards are made with many rows of color chip swatches with each row being applied at each of a long line of swatch-applying stations, e.g., up to 16 stations and rows.
