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.

The design of the modern electronic device, except for must has multiple functions, but it also trend to achieve slightness, thinness, shortness and smallness in outer appearance. In order to seek such a trend, the components disposed in the electronic device must be reduced in volume correspondingly, and the connectors used therein also must be reduced in volume without exception. For example, the USB connector has developed a mini USB connector, and the digital video signal transmission interface evolves from a digital video interface to a high definition multi-media interface having a smaller volume and a faster transmission speed.
