Direct Gravure Coater
Direct Reverse Gravure Coater

The method here involves, with a gravure roll having a finely processed surface and a backup roll for transferring coating liquid to a base material, scraping away excess coating liquid adhering to the raised areas of the gravure roll to decrease the amount of coating liquid remaining in the recessed areas, and transferring the coating liquid to the base material. Coating thickness control depends on the type and depth of engraving on the gravure roll surface. A change in the coating thickness requires you to have several types of gravure rolls with different engraving configurations.

Features

Can be used for both direct and reverse coating.
The coating thickness is easily controllable simply by changing the types of rolls.
Compatible with a variety of base materials
The coating thickness ranges from 3 to 50 µm (wet).
