The so-called digital workflow refers to the integration of the various processes and links of publishing and printing production through the computer and its network to form a digital integrated publishing system that includes pre-press, printing, post-press processing and process control and management of all-digital production operations. With digital production control information, the three sub-processes of pre-press, printing and post-press processing in printing production are connected to integrate into an inseparable system.
The digital workflow uses digital printing process worksheets instead of traditional process worksheets to carry out the transmission, control and management of information in the production process, digital proofing, direct plate making,digital PrintingInstead of traditional production operations, the digital graphics and text information to be printed are completely and accurately transferred between the processes, and finally processed into printed products, which greatly improves product quality, reduces process links, reduces time redundancy, and ensures product quality Efficient, stable and consistent.
The digital workflow includes two types of information: graphic information and print production control information flow, and not only digitalization from two aspects of information, but also an integrated production environment. Therefore, the digital workflow is to integrate various control information in the pre-press processing, printing, and post-press processing processes into the computer management, and use the digital control information flow to connect the entire printing production process into one. For example, after the printing unit receives the graphic manuscript, format, and production requirements provided by the customer, it determines the appropriate replication process route and corresponding replication processing equipment according to the basic characteristics of the printed product and the customer's requirements.
In the pre-press processing stage, after the full-page imposition, the information about the folding, cutting, binding, registration rule line and so on of the printed matter has been determined. After RIP processing, the record information of each printing plate is obtained. On the one hand, this information is used for the recording and output of film or printing plate. On the one hand, it can be used for the basic ink control data of each ink area of the printing machine during the subsequent process printing, and thus obtain the ink volume control data information without the need for the printing plate scanning. In the printing process, when debugging the printing press, you can use the registration rule lines and position data that have been generated in the pre-press stage to perform multi-color overprint adjustment, and at the same time, you can use the obtained ink volume adjustment data to perform the ink area of the printing press. The adjustment of the amount of ink without having to repeat the test printing, so that the printing machine quickly enters the official printing state, which saves materials and shortens the time spent. In the post-press processing stage, you can call the folding hands, cutting and other information that have been generated in the pre-press stage to pre-adjust the folding machine, cutting machine, and binding machine, so that various equipment can quickly enter the working state for post-press processing and production , And finally get the printed product.
Therefore, the digital workflow is to compress the information seen by human eyes into the printing space in a data way, and control these data through the computer to achieve the control of the printing process, so as to achieve accurate and reliable, highly integrated production process, so that the printing process Errors in the process are reduced to a lower level, waste is reduced to a greater extent, and production efficiency is improved.
