Digital Mold Texturing Methods, Materials, and Substrates

摘要

Commercialized methods, materials, and systems for texturing mold surfaces are presented.rnA first step involves generating a graphic file of a desired texture pattern. The graphics file is subsequently output to material deposition equipment such as an ink jet printer, which is configured to print using an acid- resistant UV-curable ink.rnThe acid etch resist ink is formulated to provide optimal properties for ink jet printing, while also providing good adhesion to metal surface and excellent acid-etch resistance to various types of acids.rnThe acid-etch resist ink is printed onto a sheet of coated film that allows the acid-etch resist to be transferred to a mold surface, after which the mold surface is etched in an acid bath.
