Perforated retroreflective film

A retroreflective particle comprising:

• a) a film having a first side and a second side;
• b) a first array of retroreflective cube-corner elements attached to the first side of the film;
• and
• c) a second array of retroreflective cube-corner elements attached to the second side of the film.

A method for forming a retroreflective structure, comprising:

• a) providing a film having a first side and a second side;
• b) attaching a first array of retroreflective cube-corner elements to the first side of the film;
• and
• c) perforating the array of retroreflective cube-corner elements and the film to remove a portion of the retroreflective cube-corner elements and the film to form an array of apertures through the retroreflective structure.

A transflector comprising:

• a) a film;
• b) an array of retroreflective cube-corner elements attached to a first side of the film;
• c) an array of apertures through the retroreflective structure within the array of retroreflective cube-corner elements, the apertures formed by removing a portion of the film and the elements;
• and
• d) a printed sheet attached to a second side of the film.

A retroreflective structure comprising:

• a) a film;
• b) an array of retroreflective cube-corner elements attached to the film;
• c) an array of apertures through the retroreflective structure within the array of retroreflective cube-corner elements;
• and
• d) a plurality of beads within the array of apertures.

A retroreflective structure comprising:
