Abstract
A business document contains a removable decal. The decal has a plastic substrate overlaid with a reflective coating including an aluminum coating and glass beads. A toner receptor coating overlies the reflective coating. A fine screen pattern is printed on the toner coating and which pattern may include jagged lines or closely spaced dots. Variable and non-variable information is then printed on the toner receptive coating. In the event of use of a solvent to alter the printed information on the decal, the fine printed screen pattern is likewise disrupted and evidences alteration of the decal.
