Description

  The present invention relates to a method and an apparatus for adjusting a varnish supply amount of a coater apparatus for applying a varnish to a printed paper surface.

  Varnish coating is used to give a high-quality feel to printed matter and to protect the printed surface. The film thickness of the varnish is important for this high-quality feeling, and when the film thickness of the varnish is thick, it can be felt as a high-quality printed matter. In addition, a thin film is required for the varnish coating on the printed material such as an intaglio printed material or a relief printed material that expresses unevenness on the printed material so as not to impair these advantages.

  Thus, in the varnish coating, the film thickness of the varnish is very important. Thus, in the roller type coater apparatus, it is already known from Patent Document 1 and the like that the supply amount of varnish can be controlled by changing the rotation speed of the original roller, and thereby the coating thickness of the varnish can be adjusted. Yes.
