Study On The Construction Of Digital Workflow Based On Publication Printing

At Drupa 2004, the digital workflow integrated with digitization, ingration and automation became the focus of the exhibition once more, it also predicted the development direction of printing industry in the future. In the future days, the automatic technicology based on CIM and PPF/JDF supported by international standard will be the mainstream of the digital workflow, and the current of digitization can't be stopped. Publication printing has a special position in the printing industry, it's different in the flexibility and complexity of folding compared with newspaper printing and commercial printing, to publication printing, the most important thing is folding. So study on the construction of digital workflow based on publication printing is very important, and the most important thing is imposing.The paper is the study on the construction of CTP digital workflow based on publication printing. It includes four points. First it introduces the digital workflow of printing industry, includes it's origion, key technology related to it such as PS/PDF , CIP3/CIP4, PPF/JDF, the main commercial workflow and how to construct a workflow; Than it brings forward the construction scheme of CTP workflow; The third is the application of standard digital workflow; The last, and the most important thing of the thesis, is the study about folding, it gives some template, which simplifies folding technology, and gives the formula to calculate crawling, which can control the precision of folding exactly.The thesis will provide scitific reference and basis to realize successful transformation of publication printing. The study of folding and crawling, can improves the product quality and efficiency greatly. The paper is valuble to construct an excellent, smooth and efficient digital workflow based on publication printing.
