A label foil is disclosed that is suitable for in-mold labeling, has a high stiffness, is well suited for cutting and is recyclable. Two short symbols are sampled in a signal received from the transmitter. The illumination beam and the shaped highlight beam are combined and provided to an imaging device that generates the image using the combined beam. The first and second data structures may view the other’s data structures using formatting from the other channel. The method may further include transitioning at least one of the power supply units based on such determining steps.
