Printing color management and print production optimization
P can be set, the purpose is to ensure that the network can be recorded on film on the right. 6) traditional printing down the standardization process, the traditional printing down the standardization process, embodied in the center of gravity of the plate is printed for the concept, high-quality, high efficiency standard production plate burning to improve the efficiency of the entire printing great contribution. Printing Down standardization process, including: maintaining a clean plate burning dust-free workshop and humidity meet the requirements to ensure that Shai Banji stable performance, to master the correct exposure and development time, use of various testing tools. 7) CTP CTP plate making the standardization of the printing plate to shorten the production cycle, improve the printing efficiency. Compared with the traditional plate-making process, CTP with the timely high quality network, and can be copied tone level range and so on. CTP plate should refer to the traditional printing down the standardization process parameters, to establish a good digital production environment.  Digital hit stick is the use of standardized digital proofing digital printing proofs directly output the original process,[link widoczny dla zalogowanych], the main purpose is to achieve customer's signature look like like. Therefore, the printing companies generally qualified customer satisfaction as a coarse quasi-proofing. But this subjective evaluation of non-professional inevitably lead to many problems. For example, when print color proofs effect can not be achieved, the customer will have a conflict between enterprises. When the print match with the proof, because no quantitative measure of corporate standard proofs, the proofs can not guarantee the quality of the next. To address these issues, printing companies must be able to develop standards for digital proofing documents, the standardized digital proofing. Including the standardization of digital proofing to choose their own digital printers and supporting paper and ink to print the data to achieve data collection for the hungry analog digital proofer color gamut printing, digital proofing system of regular inspections and maintenance. 9) The standardization of the printing press. _ Purpose of standardized printing presses and printed materials to find the best match to determine the maximum printing density and dot gain characteristics of ink, this process must be done through a series of tests. Parts of the printing press set should be based on the manufacturer's instructions for printing, including ink rollers and water rollers set the amount of compression set printing blankets, printing plates and blanket bag lining the accuracy, press enter paper, cleaning and lubrication devices, delivery systems and collection of paper chromatography paper, cleaning and lubrication equipment. On this basis, the performance matching materials and printing to determine the optimal state of the printing press, and digitization. i China Packaging 2006/42/EC. Including optimization of the production process optimization and optimization of the color ink preset control two aspects of the restoration process. (1) optimize the pre-set ink ink pre-setting refers to the determination of the default printer ink. Ink pre-set in three ways: human experience in setting, plate scan settings, ink directly from the prepress part of the default data. Human experience in setting the accuracy, efficiency depends mainly on print production personnel, and standardization of data more difficult and the formation of experience take longer. Plate scanning setting is through the plate scanner, yellow, magenta, blue, black four-color plates in the scanning and analysis of graphic information, access the default ink data storage device or network through the default data passed to the printer control center, ultimately reflected on the press. The accuracy and efficiency depends on the accuracy of the scanner plate, scanning speed and data transfer speed. The third method is generated directly from the prepress part of the default data ink,[link widoczny dla zalogowanych], the ink preset data generating system is digital workflow, digital workflow in the default data to PPF (PrintPro-ductionFormat) file transfer via memory or network to press the control center, and ultimately reflected in the press, shown in Figure 3. Comparison of three methods, the third method is faster, more stable, easier implementation and standardization of data, to better optimize the printing production process. (2) to optimize color reproduction process control optimization in Figure 3 pre-set ink color reduction process control is through a number of online printing printing quality monitoring system for real-time image acquisition and analysis,[link widoczny dla zalogowanych], and the results fed back to the pre-press and printing aspects of the console , timely correction. Optimization of color reproduction process control is mainly to establish an effective control system for automatic color reproduction, prepress and printing in a bridge of communication between the structures and improve the effective operation of press time.
