• Antihalation — Serving to prevent, reduce, or eliminate the formation of a parasitic halo around highly illuminated points on a photographic or radiographic image. In a technical sense, it refers to special films or light-absorbing layers applied to the film base to prevent the internal reflection of rays back through the emulsion.
• Flattening — The act of flattening and its direct result; the geometric or mechanical transformation of a three-dimensional body through which it becomes flat, plane, or squashed under the influence of pressure, rolling, or percussion forces. In the field of digital graphics, it represents the irreversible process of merging superimposed transparent layers into a single unified two-dimensional matrix.
