ABSTRACT:
Apparatus and methods for exposing multilayered thermal imaging media to eliminate "cloud" or "woodgrain" artifacts by proper optimization of the exposing radiation angle of incidence. The exposure angle of incidence is large enough so that all rays with high reflectance loss are paired with equally many with low reflectance loss to increase printing efficiency.
