Abstract
Compositions and methods for producing colored replicas are described. A method includes: combining a polymerizable varnish and a dye to form a composition, wherein the dye is substantially dissolved in the composition; and replicating a surface topography with the composition. The compositions and methods provide advantages in that surface topography is replicated in a color tinted polymer matrix with enhanced overall cost effectiveness.
