In one embodiment, a secure substrate provides a print-ready surface for printing scratch- off products and eliminates the need to print lower security layers for protecting against attempts to view hidden indicia information. In one embodiment, a secure substrate comprises applying micro-perforations to a dyed substrate that meets a predefined transmission optical density to resist an attempt toreduce the opacity of the dyed substrate by de-lamination. In another embodiment, a secure substrate comprises applying a lower opacity layer and a lower background layer on a substrate to provide a secure substrate that meets a predefined transmission optical density. In another embodiment, a secure substrate comprises applying a lower opacity layer on a substrate, applying a reflective coating,and applying a lower background layer over the reflective coating to provide a secure substrate that meets a predefined transmission optical density.
