Epson DirectPlate Aluminum Questions
1. How do these plates work?
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.
2. What is the highest resolution these plates will support?
The Epson Stylus Pro 7900 CTP system supports up to 175 lpi
