Abstract: As the needs of digital printing process as well as the high speed of printing, quick and personalized development make the CTP technology widely. In order to solve the problem that using CTP technology press intermediate transfer status to reproduce is not ideal, through research for printing the image histogram best reproduction methods and halftoning copy results. Collect CTP printing proofs from Zhejiang daily, Yingtian, Xinhua three companies, india through the experimental analysis by studying, measuring and mapping tone reproduction curve. Analysis on the image element tone reproduction. Analyzing the image histogram replication factors put forward to plate technology by printing the image histogram replication method and considerations. It can help improve the CTP quality image histogram reproduction.

Keywords：CTP; print quality; tone reproduction
