In recent years, many printing companies have been struggling to meet customer demand for increasingly higher quality, lower cost, and shorter delivery time. The proofing process more likely to be desired for cost efficiency because the process itself does not directly contribute to profits. Direct digital color proofing (DDCP) is a technique used to directly generate color proofs from digital data. It was introduced over 25 years ago and has since been refined. Many types of devices were developed though, the press type proof is still remaining. This paper describes the characteristics and transition of DDCP from sublimation dye transfer printer to inkjet printing, and so on, and color management problems.
