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.

Nowdays,the infrared camera in our country can export video signal and digital image signal. The video signal can display on the screen through the general grab card, but the digital one can not be inputted into computer without special image grab card. In this paper, an infrared image grab card and the correlative program driver are designed based on the analysis of the universe technology.
