Abstract
A rotary pad printing system comprises a compressible pad wheel (), one or more inkjet or other image applicator heads (), optional treatment stations (), a shaft encoder (), a control unit (), and an image source (). The image applicator heads apply an image to the wheel and the treatment stations can supply treatments such as heat, gas, light, overcoats, and undercoats. The image is then transferred to a receiving surface (). An optional cleaning station () cleans the rotary pad prior to application of the next or a continuous image. Each image can be different and can be applied to a moving surface. Since the rotary pad can continuously receive updated image information, the area printed can range from a single pixel to an image of indefinite length. In an alternative embodiment, a domed pad is used. In another alternative embodiment, a flexible belt () is used instead of a rotary wheel. In another alternative embodiment, a segmented pad () is used.
