Abstract
Methods, materials, and systems for texturizing mold surfaces is disclosed. In one method and system of the invention, a first step involves generating a graphics file of a desired texture pattern. The graphics file is subsequently output to an ink jet printer, which is configured to print using an acid-etch resist ink. The acid-etch resist ink is formulated to provide optimal properties for ink-jet printing, while also providing excellent acid-etch resist and superior handling properties. The acid-etch resist ink is printed onto a sheet of a carrier substrate that allows the acid-etch resist to be transferred to a mold surface, after which the mold surface is etched with a strong acid.
