Selected FAQ

Q:
How do these plates work?
A:
In conventional aluminum plates, the aluminum surface is the water-attracting layer. The water sits on top the aluminum, and therefore conventional aluminum plates require a relatively small amount of water to reach proper wetting for the printing process.



Epson DirectPlate Aluminum plates have a unique structure. The top hydrophilic layer serves as the water accepting layer. This layer is relatively thick and water penetrable. Therefore, when the wetting process starts, the water first saturates the hydrophilic layer, and then covers the surface. As a result it requires longer time and more water to obtain a properly wetted surface, than that required of a conventional aluminum plate.



Like polyester plates, Epson DirectPlate-aluminum plates require more water and longer wetting process before ink is applied to the plate.
