| Nowadays, with the development of digital technology such as computer, network etc. the technology of printing production is developing from traditional simulation and modulus technics to digital technics. A great many technic advantages of digital proof have appeared to which traditional proof is inferior, and will gradually substitute for traditional machine proof some day. However, neither traditional nor digital proof is constitutionally changed on the transmission of proof. There are still some problems on their circulation. Nevertheless, with the development of global economy, clients of printing enterprises spread all over the country and the whole world. It is crucial for us to offer timely and effective services. Therefore, printing industry is developing towards remote and rapidly tracing jobs and simplification of clients' proof signatures. To reduce more time and shorten the distance between enterprises and clients, remote digital proof is gradually taken on the calendar.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. |
