Features and uses

FUJIFILM RECORDING FILM for Digital Separation ETERNA-RDS 35mm Type 4791 (PET) is a black and white film intended for making archival black and white separations from color digital masters. This film is designed for a digital separation workflow using a film recorder. ETERNA-RDS offers a significant improvement over conventional non-specific separation film stock, producing finer detail, accurate gradation linearity, improved granularity and sharpness with reduced flare.

  1. 1. Exceptional image quality. Improved granularity, reduced flare and higher resolution deliver higher quality, sharper image structure.
  2. 2. Expanded latitude and linearity
  3. 3. Designed to run in either a D96 or D97 process. Photographic properties have been extensively retooled to yield enhanced linearity in both D96 and D97 processes, which simplifies calibration work.
  4. 4. Superior proven archival characteristics utilizing a PET base.


Super nano-structured Σ Grain Technology

Fujifilm has developed a technology that precisely controls the light-sensitive structure of the silver-halide grain to nanoscale, resulting in extremely fine grain. Photons generated by exposure to light are concentrated in the photosensitive nucleus via electron accumulators. The grain is designed with a precise electron accumulator structure that efficiently concentrates photons to form the latent image. The grain configuration is precisely engineered to a thickness that minimizes reflections, effectively limiting light scatter and boosting sharpness.
