A tubular article that includes a compositional mixture of an elastomer, a pigment, and a energy beam absorber. The tubular article further includes indicia formed on an outer surface of the tubular article. The indicia is formed by expanding the tubular article from a relaxed state to an expanded state, marking the outer surface with a laser, and allowing the tubular article to cold shrink from the expanded state.
