1. A method of making an identification card comprising the steps of:
providing a card substrate including first and second surfaces, the card substrate being generally shaped to include at least a plurality of substrate portions that are divided from one another by a fold line so that at least two portions can overly one another in a final card construction, the first surface having a heat activated substrate adhesive, with an activation temperature, and the second surface having a heat activated colorant adhesive that comprises a polymer suitable for adhering with colorant and for increasing abrasion resistance of second surface of the card, wherein at least one portion of the substrate is opaque; printing colorant on the colorant adhesive of at least two of the plurality of substrate portions on the second surface side, of at least one of the first and second said substrate surfaces, the colorant providing identification information of an individual, the printing including a step of adhering the colorant to the colorant adhesive by applying heat and pressure to the colorant as applied to the colorant adhesive, the applied heat being below the activation temperature of the substrate adhesive but of a level that softens the colorant adhesive for driving the colorant into the softened colorant adhesive while advancing the card substrate through a printing device; folding a first portion of the card substrate with respect to a second portion of the card substrate along the fold line so as to overly one another with the substrate adhesive of at least one portion being inward and located between folded substrate portions, wherein at least one of the first and second portions as folded is the opaque portion; and laminating the folded sections together in a heat/pressure laminator by heating the substrate adhesive above its activation temperature and applying pressure to secure the first and second portions of the card together. |
