Prepress Technology Innovation Performance (4)

The second is that the publishing or design personnel of the client transfer the various elements of the above-mentioned final product to the prepress staff with their own files. After the prepress staff performs a series of related graphic and text processing according to the publishing and printing requirements, the final digitization is formed. Print pages, convert them to Postscript PDF files, or provide digital proofs to the customer after RIP interpretation. Check and confirm. The confirmed documents finally output the printing plate or screening film through the output device. At the same time, the ink preset parameters and the post-printing are output through the CIP3CIP4 software. Processing parameters for printing and finishing workers.
At present, this kind of pre-press digital network connection uses the Internet or satellite communication equipment to exchange data directly with long-distance communication. The increasingly mature soft proofing technology also makes it easier for related parties to communicate with each other, and is easy to find errors. , Corrected in time; various professional software and digital platforms also make the maximum degree of optimization of both page content and control information, so that the experience of associated parties can be shared to the greatest degree, effectively ensuring the realization of higher reliability.
2. Based on the quality of the color management system to improve reliability <br> The quality of modern printing products depends mainly on the color management system of the printing company's technical level and control accuracy. As the key to the modern prepress technology, the color management system not only inherits the advantages of traditional color control, but also adopts an all-digital way to simplify the control of complex color reproduction so as to obtain the “what you see is what you get” result.
At present, domestic application of color management systems to improve the reliability of printing quality requires the establishment of stable printing process benchmarks, printing process control systems, digital soft proofing and digital hard proofing and other technical parameters, especially digital soft proofing, digital hard proofing and actual The consistency of printing samples. In addition, it is necessary to solve the current differences of views and opinions on color proofing purposes. For example, some people think that color proofs should allow customers to understand the ideal state of the final print. Some people think that the proofs should be consistent with the originals being separated, and others think that the proofs should be It is an accurate reproduction of the original image art. However, from the point of view of the printing profession, the purpose of color proofing should be to provide an accurate reproduction of the final print, reflecting the requirements for the reproduction of the image art under certain limited printing conditions.
The color management system describes and controls the color difference and color gamut by means of numbers. It not only eliminates the color error between proofs and prints, but also maintains the color consistency between the proofs and the prints. It can also be digitally controlled for various printing methods. Matching enables prepress operators to use the same format of text and graphics data to produce products with different printing methods, and to enable the product to be consistent with the proofs in terms of color, level, and clarity, and to satisfy the check and correction of all elements on the page. Requirements, but also to maintain a high degree of reliability. Representatives of such systems are color management systems such as GMG, EFI, and X-Rite.
3. Time and cost reliability improvement based on digital production process <br> In the development of marketization and personalization of information dissemination and publishing, how to shorten the time from manuscripts to readers and reduce the cost of printed matter is increasingly important. The digital production process can not only adapt to the production process and methods of popular products, but also adapt to the on-demand printing of the user's production processes and methods, and can also minimize the cost of the product.
Digital production process and its seamless connection with CIP3CIP4, JDF, and even upstream content providers' electronic publishing systems and data systems, has established a set of the most effective methods for the detailed control of various operations of printed products, and can provide users with the least number of prints. The “1” can be used to create a “universal”, diversified production model. Printed materials can also be designed and organized according to user preferences and personality.
The content and marketing of printed products can also be done directly on the Internet. The digital production process adopts a completely digital and clustered control method, which minimizes the subjective factors of the operators, and reduces or eliminates the influence of various factors in graphic transmission, plate making, printing, and post-press processing, thereby effectively improving The reliability of printing production time and cost.
Prepress technology has moved from a single advanced hardware-driven era to a software-led era based on advanced hardware. The soft and hard integration of pre-press and digital technology is creating a new era of advanced digital technologies for printing industry applications, such as printing product planning, process design, process and quality control, printing and post-press processing optimization, systematic solution and cluster control.
How China's printing companies scientifically apply advanced prepress technology to achieve advanced equipment application optimization, printing process innovation and management model changes has become the key to the construction of the core competitiveness of printing companies, but also print companies to fully understand and master new technologies, new The characteristics and laws of technology and new materials, and the best way to achieve modern digital leading production and management of resource integration.
