Digital minilabs can facilitate the enhancement of prints from colour negative films as well as printing from digital cameras and a wide range of digital storage media.A number of printing technologies have been considered for digital photofinishing including ink jet, thermal dye transfer (D2T2), electrophotography and AgX technology. In the last couple of years a number of photofinishing solutions, based on these technologies, have appeared in the market place.The expectations of the consumer are that the digital photos will match those produced from colour negative film using AgX technology. The different output technologies will be considered and contrasted to AgX output.
