The method for forming a retroreflective sheeting includes providing a first layer and forming a prism array on the first layer. A second layer is applied to the prism array. The first thermoplastic layer is welded to the second thermoplastic layer, while applying a die having a plurality of cells with multi-course, hatched patterned perimeters to the layers to dislocate a portion of the prism array, thereby allowing the first layer to be bonded to the second layer at the portion.
