Introducing the Hirano Kiss Reverse Gravure. Thus, the gravure reverse method is using the kiss touch style transfer. In comparison to the direct method, this method stresses the substrate less and results in a good coating surface. Therefore, the Reverse Gravure uses kiss transfer. Consequently, the substrate side conditions will affect the output. In conclusion, this is not for high-speed coating.

A gravure coater is a kind of roll coater, in which the resin is applied to an engraved roll. Typically, a blade scrapes the resin off, leaving an appropriate amount in the engraved cells, and the remaining resin in the cells is then transferred to the substrate to form a film.
There are many distinct types of this method, depending on the roll configuration, transfer method, and blade structure.
All these types are widely used as they are mostly suitable for thin coating, while easily accommodating high speed and high versatility.
Various patterns of combinations are available other than those described below.

Hirano Kiss Reverse Gravure Features:

A method in which transfer in the gravure reverse method is done using the kiss touch style. In comparison to the direct method, this method stresses the substrate less and results in a good coating surface. As it uses kiss transfer, it is likely to be affected by the substrate side conditions, and it is not well suited for high speed coating.

Low coating amount, low viscosity resin applications, good coating surface, and good coating quality. Thus, a reference range of application coating speed:1~100m/minViscosity:1~500mPa･sCoating amount:1~100μm･Wet. Use examples: Optical functional materials, release agent coating, etc.
