    • A roll to roll microreplication apparatus is described. This apparatus forms a microreplicated article including a web having first and second opposed surfaces. The apparatus includes a first patterned roll, first nip roll and first coating die; the first coating die is disposed adjacent the web substrate first side and the web substrate is disposed between the first patterned roll and first nip roll. The first nip roll touches the web substrate second side and the first patterned roll touches the web substrate first side. The apparatus includes, a second patterned roll, second nip roll and second coating die, the second coating die is disposed adjacent the web substrate second side and the web substrate is disposed between the second patterned roll and second nip roll. The second nip roll touches the web substrate first side and the second patterned roll touches the web substrate second side. A drive assembly is configured to rotate the first patterned roll and the second patterned roll such that the first and second rolls maintain a continuous registration within 100 micrometers. Methods of making a microreplicated article are also disclosed.

    • A sheeting and a method of forming a sheeting from a master tool are described where the sheeting has a composite image that floats above or below the sheeting. The method includes providing a first sheeting comprising a first array of microlenses and a photopolymerizable first material layer adjacent to the first array of microlenses. Another step is exposing the first sheeting to a radiation source to form a master tool comprising a plurality of polymerized first structured areas in the first material layer, wherein at least some of the first structured areas include a portion shape in common with at least some of the first structured areas and wherein each first structured area is associated with one of the first array of microlenses. Yet another step is replicating the plurality of first structured areas using a substance that conforms to the plurality of structured areas to form a second material layer having a plurality of replicated structured areas.
    • 描述了从主工具形成片材的片材和方法,其中片材具有漂浮在片材上方或下方的复合图像。 该方法包括提供包括第一微透镜阵列的第一片材​​和与第一阵列微透镜相邻的可光聚合的第一材料层。 另一步骤是将第一片材暴露于辐射源以形成包含第一材料层中多个聚合的第一结构化区域的主工具,其中至少一些第一结构化区域包括与至少一些 所述第一结构化区域和其中每个第一结构区域与所述第一阵列的微透镜中的一个相关联。 另一步骤是使用符合多个结构化区域的物质来复制多个第一结构化区域,以形成具有多个复制结构区域的第二材料层。
