    • Methods of making tiled articles and molds used to make retroreflective articles. The methods include forming a prism array on a master substrate and forming a replica of the master. A reference edge is formed on the replica, thereby reducing the size of the prism array, yet maintaining a lateral dimension of the replica to maintain ease of handling of the replica. The replica is copied and the reference edge on the copied tiles are exposed, such that the reference edge can be mated and secured face-to-face with a reference edge on other tiles in order to form a tiled article. The tiled article is used as a mold to produce retroreflective articles or can be further duplicated and mated to form larger tiled articles to be used as molds. Tiled articles used as molds and retroreflective articles produced from the molds are also disclosed.
    • 制造用于制造逆向反射制品的瓷砖制品和模具的方法。 这些方法包括在主基片上形成棱镜阵列并形成母版的复制品。 在复制品上形成参考边缘,由此减小棱镜阵列的尺寸,同时保持复制品的横向尺寸以保持复制品容易处理。 副本被复制并且复制的瓦片上的参考边缘被暴露,使得参考边缘可以与其他瓦片上的参考边缘面对面地配合和固定以形成平铺物品。 瓷砖制品用作制造逆向反射制品的模具,或者可以进一步复制和配合以形成更大的瓷砖制品以用作模具。 还公开了用作模具的瓷砖制品和由该模具制造的逆向反射制品。
