These benefits are derived from the elimination of film and the on-press efficiencies stemming from improved quality plates. Frances Cicogna, packaging segment marketing manager for Agfa, points out a major difference between the current state of CtP for flexo vs. CtP for offset.

Computer-to-flexo uses a digital mask in which film that is pre-applied to the plate is imaged―the plate is then exposed and processed conventionally.
