    Abstract: The present invention discloses a process and device for preparing laser PVC. The device includes an upper transmission roller, a support mechanism, a spraying mechanism, an impurity removal mechanism, and a lower transmission roller; the upper transmission roller is disposed above the lower transmission roller, and the two are configured to implement delivery of a PVC film at a station for preparing a laser layer by spraying; the support mechanism is disposed between the upper transmission roller and the lower transmission roller and is in contact with a back surface of the PVC film, and the spraying mechanism is disposed opposite to the support mechanism; and a curing mechanism is disposed in a fitting manner at the coating position; and the impurity removal mechanism is disposed at a front end of the spraying mechanism.

    Abstract: Systems and methods in which dot-like portions of a material (e.g., a viscous material such as a solder paste) are printed or otherwise transferred onto an intermediate substrate at a first printing unit, the intermediate substrate having the dot-like portions of material printed thereon is transferred to a second printing unit, and the dot-like portions of material are transferred from the intermediate substrate to a final substrate at the second printing unit. Optionally, the first printing unit includes a coating system that creates a uniform layer of the material on a donor substrate, and the material is transferred in the individual dot-like portions from the donor substrate onto the intermediate substrate at the first printing unit. Each of the first and second printing units may employ a variety of printing or other transfer technologies. The system may also include material curing and imaging units to aid in the overall process.

    Abstract: A system and method for applying an overcoat to a printed image on a substrate generally includes a radiative source that transmits electromagnetic radiation within a predefined wavelength range to the printed image on the substrate to be absorbed by the printed image and heat the printed image to a predetermined temperature range, a depositing device that deposits an overcoating powder onto the heated printed image, the overcoating powder having a melting point within the predetermined range such that upon deposition thereof, the overcoating powder adheres and/or melts onto the heated printed image, and a residual powder removing device that removes any residual overcoating powder not adhered to the printed image or the substrate.
