Coating material applying method and coating material applying apparatus for applying a coating material to surfaces of prints, and a printing machine having the coating material applying apparatus
A coating material applying apparatus according to this invention includes a guide board, a droplet spray nozzle head, and an ultraviolet light emitting device. The guide board has numerous suction bores formed in a surface thereof and connected to a vacuum pump. The droplet spray nozzle head is disposed opposite the guide board, and has numerous droplet spray nozzles. The nozzles spray ultraviolet-curable varnish to printing paper transported toward a paper discharge station. The ultraviolet light emitting device is disposed opposite the guide board, and adjacent and downstream of the droplet spray nozzle head with respect to a direction of paper transport, for emitting ultraviolet light to the printing paper having the ultraviolet-curable varnish applied thereto.
