Abstract
A digital roller mold manufacturing system for manufacture of exterior characteristic structures on a roller mold depends on an illuminator for generation and projection of a light source on a Digital Mirror Device (DMD) chip in which micro-mirrors are rotated a controllable angle for defining the light source as an optical image and projecting the optical image on first micro-lenses at which digital light energy is transformed from the optical image and transmitted to first optical fibers, second optical fibers via couplers, and second micro-lenses. Furthermore, the second micro-lenses focus the digital light energy as light spots which are received by a photo-resist layer externally covered on the roller for development of patterns with exterior characteristic structures on the roller mold because a control unit regulates rotations of the roller and horizontal shifts of second micro-lenses.
