Retroreflective sheeting and a method for making the same includes a plurality of open-faced cube-corner surfaces formed from a substantially rigid material to keep the cube-corner surfaces from flexing. An optical coating is formed on the surfaces, and a fill layer is attached to at least a portion of the optical coating. A plurality of voids form the open-faced cube-corner surfaces.

Durable, open-faced retroreflective prismatic construction

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 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.

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.

A continuous process for producing printed patterns on retroreflective material is disclosed, wherein a partially cured pattern is printed on a roll of film and partially cured cube-corner prisms are bonded to the film over the printed matter thereby encapsulating the printed matter to protect the printed matter from the environment.

A method and apparatus for forming 'seamless' retroreflective sheeting is described. At least two mold surfaces are used, each having alternate areas of arrays of prism recesses and spaces. In a first step, prisms are formed in one of the mold surfaces and applied to a base film or web. Next, prisms are formed on the second mold surface and applied to the spaced areas left in the first step.

A method and apparatus for forming retroreflective sheeting with improved daytime whiteness performance is described in which air spheres are encapsulated into the prism structure when the prism base body is laminated to the prisms in a mold.
