摘要
A master tool and a method of using a master tool for forming a sheeting are described where the sheeting has a composite image that floats above or below the sheeting. The master tool includes a first sheeting have a first array of microlenses and a photopolymerized first material layer adjacent to the first array of microlenses. The photopolymerized material is polymerized upon exposure to conditions resulting in simultaneous absorption of two or more photons. The first sheeting includes polymerized structured areas in the first material layer. At least some of the structured areas have a portion shape in common with at least some of the other structured areas and each structured area is associated with one of the first array of microlenses.
