Abstract

This application discloses methods of preparing a work roll for applying a dulled gloss finish on a metal substrate surface. The resulting finish has a fairly uniform glossiness with a slightly matted appearance and with minimal directionality. The work rolls have an Ra value of from 0.2 to 0.4 μm and an Rz value of less than 3.0 μm. Methods of forming a dulled gloss finish on a metal substrate are also described herein.
