Abstract: A method includes applying a transferrable material to an outer surface of a casting plate to form a pattern on the outer surface of the casting plate. After applying of the transferrable material, a composite material is applied to the outer surface of the casting plate to form an inflatable membrane. The composite material covers at least a portion of the pattern and includes a florescent material and a pigment material. The inflatable membrane is cured to allow removal of the inflatable membrane from the casting plate. The inflatable membrane has an inner surface having the pattern detectable upon receiving of light causing the fluorescing material to emit florescent light.
