US 11,685,181 B2 · Multilayer identification patches

Abstract

A multilayer identification patch comprises a reflective layer and a design layer on top of the reflective layer. The design layer comprises an opaque body and at least one identification symbol void (ISV) to allow light to reflect from a portion of the reflective layer via the ISV. The opaque body of the design layer comprises multiple layers of cured photopolymer ink. The multiple layers of cured photopolymer ink comprise an opaque layer of colored photopolymer ink. In one embodiment, the multiple layers of cured photopolymer ink in the opaque body of the design layer further comprise a layer of clear photopolymer ink under the opaque layer of colored photopolymer ink. Other embodiments are described and claimed.
