Firstly this paper dissertates the significance, principle, workflow and characteristics of remote digital proof. Moreover, it puts forward the color management scheme of remote digital proof. And then, through experiments, it describes the process of native digital proof, including setting up ICC Profile which reflects printing characteristics, basic linearization and digital proofer's linearization, setting up ICC Profile which reflects characteristics of digital proofer's paper and ink, and so on. On the basis of that, the process of remote digital proof is set up and realized, including setting up original proof and remote proof. Besides, the chromatism and resolvent is analysised. The color consistency between the two digital proofers is realized. Finally, by setting up RSA digital signature of remote digital proof, the security of network transmission and validity of digital signature is assured.

With the development of computer and network technology, there are more and more applications of digital contents which are easy to be copied, modified and spread. Because of these features, the digital contents are also always under the risk to be filched, juggled, accessed without authorization and illegally distributed. The digital contents can hardly be protected effectively in the network environment due to its large-scale disordered distribution, which has hindered the development of the applications based on the digital contents.
