Document Type and Number:
WIPO Patent Application WO/2007/135900
Kind Code:
A1
Abstract:
This invention provides a gravure engraving roll, which is improved in durability
over the conventional gravure engraving roll, on which a resin layer has been
exposed, and has prolonged service life, and a method for manufacturing the same.
The gravure engraving roll comprises a plate parent material, a resin layer provided
on the surface of the plate parent material, a gravure cell provided on the resin
layer, and a surface reinforcing covering layer provided so as to cover the surface
of the resin layer and gravure cell. Preferably, the surface reinforcing covering
layer is a DLC covering layer, a silicon dioxide covering layer, or a chromium
