摘要： A textured work roll can impart a desired texture on a metal substrate, such as an aluminum or aluminum alloy sheet. The textured work roll can be used for applying a gloss finish on the metal substrate. The textured work roll can be textured by grinding the work roll to form a ground work roll; electro-discharge texturing the work roll to form an electro-discharge textured work roll; and polishing the work roll to form a polished work roll. The polished work can have an Ra value between 0.30 μm and 0.70 μm. The polished work roll can be used to apply the gloss finish on the metal substrate.
