摘要：
In one embodiment of the invention, a master tool is disclosed including a top plate, a plurality of buttons, and a releasable locking mechanism. The top plate has an array of openings and a top side with a background patterned surface. The plurality of buttons are in the array of openings and configured to be repositioned to selectively orient their orientable patterned surface into a different orientation with respect to the background patterned surface. The releasable locking mechanism releasably locks the position of the plurality of buttons within the array of openings to hold the selected orientation of each orientable patterned surface with respect to the background patterned surface to provide a top surface pattern. The top surface pattern of the master tooling may be transferred to form a surface pattern into retro-reflective sheeting during its manufacture.
