JDF as the basis of digital printing, as early as drupa2004 has been vigorously preached, and by the drupa2008, most of the suppliers products now supports JDF, Also can say. Printing digital has already kick off.
CTP technology as the important mark of digital prepress, after nearly 20 years of development has a greatly improved in the integration, speed, format, and precision degree. The company where the author as the first introduced CTP technology enterprises, after ten years of application of exploration and development, in the construction of a digital prepress production process has accumulated a certain experience, with the reader here share.
Prepress digital definition
What is this digital prepress? There are two layers of understanding.
One is the digital equipment: the traditional hard copy, layout, and other functions of the network, For example, no longer use traditional silver halide film cameras, but directly use digital camera to collect original. Instead of using traditional film composition, but directly on the computer with typesetting software. The digitization of single equipment is the basis of the whole production process.
Two is the process of Digital: with the digital workflow series each link (production instructions, file receive, file production, soft proofing, digital proofing, printing plate production, etc.) reduce data conversion and on-site personnel experience to participate in, to achieve paperless, automated production transfer. For example, the removal of paper production orders, imposition and color information with prepress automation process realized the link between the seamless transfer and docking.
On the basis of CTP Digital prepress printing.
Printing production mode in the traditional analog printing or printing simulation and digital printing hybrid can be simply summarized as physical carrier transitions + human tracking + storage and transportation mode, all the intermediate products, such as film, separations, the phototypesetting film, plate, proofs and raw materials are in form of physical carrier, relying on warehousing and transportation way to allocation and distribution. And all digital production mode can be summarized as digital information processing + mass storage + network transmission mode, in front of the finished products, print publication is completely in the digital mode of existence and control.
CTP technology as Prepress digital is an important symbol, in the production of plays a huge role, printing quality and production efficiency are compared with traditional CTF technique have greatly improved. CTP and digital work flow of data processing and exchange process from the scanning input, file processing, digital proofing, direct printing plate to the printing and so on. A complete CTP system, not just a plate making machine, but also the key is to establish the ideal digital workflow.
