Methods and apparatus, including computer program products, for recommendations based on adoption curve. The output circuit is used for outputting a supply of main power source. Preferably, the transfer film web is moved only when the color pattern is being printed and when it is otherwise necessary to prevent the film web from being worn through as the black pattern is printed. The second segment has a profile sufficiently high such that, when the second segment cycles through the upper cycle portion, at least one section of the second segment extends above the plane defined by the tops of the first and second rollers to engage and at least partially lift the article for directional transition. Typically, the equalization process is computationally expensive.
