Color management cannot be achieved overnight

in recent years, color management has become a hot topic in the industry. More and more people realize that in order to get the best output effect in the digital workflow, each device in the workflow should keep the same color; In today's increasingly fierce market competition, color management has become a key factor for enterprises to retain customers. Truth color management can not only realize "what you see is what you get", but also improve efficiency, reduce costs, improve customer satisfaction and enhance the competitive advantage of enterprises. What stage is the current color management application in China? What are the problems in the application? How will it develop in the future? We interviewed several industry experts and asked them to talk about their views from different perspectives

domestic color management application is still in its infancy

prepress expert yinyoufang: color management technology is a high-tech that people in the industry are very concerned about and interested in. In recent years, it has indeed made new development and progress. Color management system is indeed a powerful auxiliary tool to realize "what you see is what you get". Whether color management is used in scanners, monitors, or digital proofing, people will find that it is very different to use it or not. The color management system provides an indispensable means for the prepress process, which can make the image processing personnel without enough experience make better products

lijiaxiang, Secretary General of the National Printing Standardization Conference: if printing enterprises want to enter the high-end printing market, they must adopt color management technology. Generally, the color management we refer to involves the whole process from scanning input, screen correction, digital proofing to printing. Some people abroad also divide the color management into three parts: input, display and output. Color management technology has been applied in China for more than 5 years. Since 1997, domestic insiders have begun to pay attention to color management, but the application of color management in China is still in its infancy. The application of color management in the domestic printing industry is not active, but passive. For example, color management has to be adopted when buying a scanner; After buying digital proofing, we have to use color management. Many people are at a loss about whether and how to make good use of color management

ZhangGuiLan, senior engineer of China Institute of Printing Science and technology: Yes, many enterprises do not take the initiative to realize that color management should be adopted, but because they buy scanners and the scanners themselves have color management. However, there are still many people who simply finish scanning with the scanner, and just make a little adjustment in Photoshop. There is no color management at all. The use of the monitor is also the same. It is often used immediately and never adjusted. Since 1998, the relevant professional media have introduced more knowledge of color management and published many articles, but there are not many printing enterprises that really implement color management

the stability of printing process is the premise of color management

lijiaxiang, Secretary General of the National Printing Standardization Committee: I have stressed on many occasions that if you want to really make good use of color management, you should not only have good software and hardware, but also the most important thing is that the printing process should be stable, that is, the stability of printing process is an important prerequisite for making good use of color management. It is necessary to stabilize and standardize the pressure, point increase, printing paper, ink and other conditions of the printing machine. Now some enterprises pay more attention to the evaluation of a color management system, but ignore how the color management system can be used in the day 3 Tensile strength( σ b) This problem is often used well in production. Some enterprises only pay attention to the installation and debugging of the system, but ignore how to make the system work more stably. Compared with foreign countries, the main gap between us and foreign countries is that the post printing process is unstable. In addition, there is a problem of consciousness. Many people don't know how to make good use of color management. Some enterprises don't know that the parameters of the profile need to be readjusted when the conditions of the printing machine or the printing equipment used, or even after the printing color sequence is changed. For a long time, domestic printing enterprises have been managing by experience. In order to realize color management and make good use of color management, they must jump out of experience management and realize standardization, digitization and standardization

the linearity of print sensor elements has reached a very high level. Former expert yinyoufang: color management technology is not a magic wand. Many people think that once they have a color management system, they can achieve "what they see is what they get" and easily make good products. However, the current color management system is indeed far from the requirements of the actual printing production. The color management system is not as flexible as people think. It is not that as long as the color management system is installed, it will be able to make good prints. Color management itself is a complex system engineering. It has many variable functions. It can not be completely "solved" by a few characteristic steps. The basic premise of color management is to have the basis of standardization. Without the standardization of each process, there should be no basis, and color management is difficult to be effective. The biggest problem in the application of color management in China with the continuous improvement of vehicle polyurethane material technology and process, abundant production capacity and gradual decline of cost is precisely that the printing is not standard, and it is common to see without measuring instruments based on experience and flesh eye. To do a good job in color management, besides the printing press should be in the best working state, the field density should be stable, and the raw materials should be stable, there should also be measuring means and tools such as ladder, color code, density meter, etc

ZhangGuiLan, senior engineer of China Institute of Printing Science and technology: some printing enterprises may know densitometers, but they lack understanding of spectrophotometer and other measuring instruments and will not use them. Some color measuring instrument suppliers also complain that the sales and promotion of their products in the printing industry is far less easy than that in the imaging industry. The photography and imaging industry has put color management as the current focus. In contrast, in the printing industry, which needs color management most, it is obvious that people do not pay enough attention to it

lijiaxiang, Secretary General of the National Printing Standardization Committee: the extent to which users can intervene in the color management system that domestic users are using cannot be ignored. It may not be expensive to buy a set of digital proofing software, but it may cost 70, 000 yuan to buy a set of related testing instruments, but measuring instruments are necessary. Users can't just buy software without measuring instruments

making good use of color management technology is a top priority

lijiaxiang, Secretary General of the National Printing Standardization Committee: how to make good use of color management technology is a top priority. Printing enterprises should pay more attention to how to stably apply color management technology and how to make good use of it. The work that needs to be done is far from as simple as introducing a scanner, buying a display or a digital proofing system. There is still a lot of work to be done and there is still a long way to go

prepress expert yinyoufang: the color management system is indeed developing with each passing day. The color management technology is constantly improving, and the software and hardware of color management are also constantly maturing. Now, we are glad to see that there are not only mature color management software, accurate color measurement instruments, but also perfect overall solutions in the market. Printing enterprises should not only strengthen the understanding of color management technology and care about the development of color management technology, but also dare to practice and actively adopt it. Based on the principle of "easy before difficult", it should be gradually implemented by stages and projects, and the mature should be used first, gradually improved, improved in practice and benefited from application. Professional and technical personnel engaged in color management should pay attention to overcoming impetuous emotions, devote themselves to research, do a solid job in standardization, standardization and digitization, seriously study the relevant knowledge of chromatics, and combine theory with junior high school

Zhang jialanhua, senior engineer of China Institute of Printing Science and technology: to promote (signing ceremony) the application of color management in China, we need to make joint efforts in many aspects. On the one hand, printing enterprises should deepen their understanding of color management technology; On the other hand, relevant suppliers should also go down to the printing enterprises to hold more on-site demonstration activities, so that users can witness the contrast effect of using and not using color management. Let users understand that although the price of a color measuring instrument is tens of thousands of yuan and the price of a set of color management software is not cheap, the benefits to enterprises after adopting color management technology may be hundreds of thousands of yuan, or even millions of yuan

lijiaxiang, Secretary General of the National Printing Standardization Committee: it is worth noting that at present, people in China are more concerned about the WYSIWYG problem of digital proofing in color management, and do not pay enough attention to the color management of scanners and monitors

prepress expert yinyoufang: that's true. Domestic color management is used more mature in the field of digital proofing, and the effect is obvious. But in general, the application of digital proofing is not popular, but digital proofing in gravure printing field in China is still used early and popular

lijiaxiang, Secretary General of the National Printing Standardization Committee: to make good use of color management, enterprises must also have corresponding talents and certain R & D capabilities. If enterprises do not have ready-made talents, they must rely on basic training. For enterprises, it is no problem who will train and where to train. The problem is how to retain trained employees and prevent brain drain

from the experts' talks, we can see that color management cannot be achieved overnight. To achieve the goal of color management and achieve the expected results, enterprises must be down-to-earth, do a solid job in data, standardization and standardization, and overcome the idea of being eager for quick success and instant benefit. To make good use of color management, in addition to the attention of enterprise leaders, there must also be corresponding talents. Relevant training for employees is required. Although the training may affect the immediate profits of the enterprise, it will certainly play a positive role in enhancing the future competitiveness of the enterprise. The application of digital technology in the printing industry is becoming more and more popular, and color management will be the general trend. We believe that with the maturity of color management software and hardware, the popularization of color management technology in China, and the joint efforts of many parties, we will be closer and closer to "what we see is what we get"
