【摘要】 当今,随着计算机、网络技术等数字化技术的发展,印刷生产技术与工艺已开始从传统的模拟或模数混合工艺向数字化生产工艺变革。数码打样已经凸现出了许多传统打样所不及的技术优势,并将在一定时期内逐渐替代传统的机械打样方式。但是,无论是传统打样还是数码打样,样张的传送很大程度上没有实质性的变革,它们在流通上仍存在一定的问题。然而,随着世界经济全球化的发展,印刷企业根据业务拓展的需求,客户遍布全国乃至全球,这样提供及时有效的服务也越来越重要,因此,印刷业朝着远距离快速跟踪作业以及简化客户签样的方向发展。为了进一步减少时间,缩短与客户的距离,远程数码打样也逐渐提上了日程。 本论文首先阐述了远程数码打样的意义、原理、组成及特点,并提出了远程数码打样的色彩管理解决方案;然后,通过实验说明了本地数码打样的输出过程,包括创建反映印刷工艺特性ICC Profile、数码打样机基本线性化及数码打样机线性化、创建反映数码打样机纸张、墨水特性的ICC Profile等等;在实现本地数码打样输出的基础上,基于Best Remoteproof建立和实现了远程数码打样,包括创建本地校样和远端校样;并且分析了色差数据以及解决方法,实现了两台远程数码打样机之间的色彩一致性;最后,通过建立远程数码打样的RSA数字签名方案,保证了网络传输数据的安全性以及数字签名的有效性。更多还原

【Abstract】 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.更多还原
