  • Patent number: 8042463
    Abstract: The invention discloses a varnish coating device that utilizes an ordinary conventional digital stencil printing apparatus, such that anyone can easily apply a uniform film of a viscous coating onto a predetermined area of, for instance, covers and surfaces of printed products. The invention functions as a varnish coating device, in place of a drum unit, when a varnish coating unit is mounted on a mounting section of a printing apparatus main body. The varnish coating unit has: a coating roller that coats the surface of printed paper with a transparent varnish liquid and feeds out the paper; a supply device having a doctor roller that forms a liquid pool on the coating roller and that supplies varnish liquid to form a coating in a predetermined thickness over a predetermined area of the surface of the coating roller; a cradle that detachably supports a varnish container; and a pumping device.

  • Patent number: 7963220
    Abstract: A stencil printing apparatus in which the generation of discharge sheet peeling problems and defects such as creasing and tear of the stencil base sheet can be prevented while printing on a coated sheet. When a printing sheet set in a sheet-feed device is indicated by input via a sheet-type input device as a coated sheet, or when a printing sheet set in a sheet-feed device is automatically detected by a sheet-type detection device as a coated sheet, a control device judges on the basis of a detected signal from the base-sheet type detection device whether or not the stencil base sheet type set in the platemaking apparatus is for coated sheet printing, and permits platemaking start if the stencil base sheet is for coated sheet printing and issues a warning without permitting platemaking start if the stencil base sheet is for non-coated sheet printing.
