Abstract
A process for preparing a sign that includes the steps of providing a sheet of material; defining on a surface of the sheet a series of image-bearig areas and non-image-bearing areas; treating the surface of the sheet with an essentially solvent-free composition comprising a colorant and a polymeric binder to selectively deposit the composition on the non-image-bearing areas of the surface of the sheet; and fusing the composition to create a continuous polymer film on the non-image-bearing areas.
