This process involves forming a composite consisting of a fluorescent dyed positive epoxy replica of a portion of a type band coated with a vapor-deposited metal layer and covered with clear epoxy. This enables observation of the profile of a specific character or portion of a type band during various process and stages without destruction of the band. Referring to the figures, the procedure for making the composite is as follows: 1. Creating the negative. As seen in Figs. 1 and 2, a negative 10 of the character of type band 11 to be observed is cast using a room temperature vulcanizing rubber molding compound 12. 2. Creating the positive. Negative 10 is cast in fluorescent dyed epoxy 13 to make positive replica 14 of the character being investigated. (See Figs. 3 and 4.) 3. Metallization of replica 14.
