Reflection: the current situation of color management in China's printing industry

printing is a very wonderful discipline: it has a long history and is all inclusive. However, different people have different opinions about it: some people mention that printing will still stay in the period of manual mimeograph, but more and more people are aware that printing is a cutting-edge discipline that integrates "light", "electricity", "machinery", "chemical industry", computers and other high-tech digital equipment; At the same time, as a traditional manufacturing industry, it also needs a good reserve of marketing and management knowledge in order to finally achieve high-quality products recognized by the market

prepress processing has always been recognized as a link with high technical content in the production process of the printing industry, and it is also the key to the control and management of the printing workshop. However, recognition is a level, including many professionals engaged in printing (here mainly refers to the process and technical personnel in the production line), and few people can really know prepress knowledge like the palm of their hand. In particular, color management in printing is a broad and profound knowledge, which runs through the whole process of printing production and covers almost all basic disciplines of science and engineering, namely 1 As a person who studies printing in a scientific class, he will have a vague understanding of chromatics if he does not take it as his main direction of attack. And now the printing education in our country generally puts the mechanical subject in the first place, so this kind of technical process in line with digital equipment has not received the corresponding attention from the beginning of talent training, and it is not difficult to imagine with the development of technology

but speaking of it, many printing enterprises may not feel uncomfortable because of the lack of "color management". It is generally believed that as long as the machine rotates, there will be product output, and it seems that the corresponding buyers can be contacted regardless of the quality. Earn more for good products and less for bad ones. Of course, we are not unaware of the market's desire for high-quality products, but we are either unwilling to invest in human and material resources, or we are not sure about the direction of our efforts. Therefore, it is not surprising that "color management", which is praised by domestic and foreign experts as "at the core of the entire management and control chain of Indian enterprises", is not recognized by the public, or even known by the public

the core idea of this technology can be simply summarized as follows: finally realize or try to realize "color is independent of equipment", that is, the relevant data of printing images obtained on one equipment can be correspondingly restored on another machine and equipment, throughout the whole process of printing production. There is another simple description in chromatics, namely "objectivity of color"

an ideal color management process can be summarized as follows: 1 Determine the color performance characteristics of the display: some color management systems preset the display color profiles provided by various manufacturers to form a comprehensive internal preset file profile library, which can be called when determining the color characteristics of the display. 2. Calibrate the display. Adjust the white dot and other display characteristics of the display to meet your output requirements. For example, if it is output to the printing medium, the white dot of the display can be calibrated to the color temperature of the printing paper. 3. Determine the characteristics of the scanner or other input devices. If the color management system provides an it8 sample, it can be scanned or photographed. Then compare the obtained color value with the standard color value, and record all the difference information as the profile file of the scanner for scanning. 4. The color management system converts the scanning results into the color space of the display. 5. Determine the characteristics of color printing and output equipment. That is, select a color feature description file for the color printer, printing conditions and other output devices supported by the color management system. 6. The color management system uses the overview documents of the display and printing machine to change colors. Some systems allow "soft proofing" on the screen (that is, CMYK color on the screen)

the current situation of color management application in China has a feeling of "being too high and too low". Although basically every printing industry summit Management Forum will arrange a special report on it, even more than one, the appeals of experts seem to be drowned in the sea in practice. There are countless foreign manufacturers specializing in color management. However, in China, except for founder, which is relatively well-known, others have not been widely used in production practice. That is, the enterprise has introduced the whole management system with a huge amount of money. What is the result

it is reported that only a few well-known printing enterprises such as Yachang and Caihong adopt color management in Chinese enterprises. Although other top ranked businesses in China will also be very interested in this, even if they buy color management equipment, they often just catch up with the tide or do something that makes people feel worried after listening. For example, an enterprise spent a lot of money to buy a set of the most advanced prepress processing equipment, but in addition to the digital proofing machine, including a full set of color management system and other instruments are basically in an unopened state. The reason is that no one can use it

as a process technology that has been widely used in the production line abroad, our gap is more than a little bit? Although the equipment manufacturer will also help us to familiarize ourselves with the whole process, we often only get familiar with the equipment in the end! Here is another talent issue. Because such topics are already cutting-edge technologies and require quite good and solid basic theories of science and engineering, based on this, we should also place more hope on Colleges and universities and scientific research institutions. As colleges and universities with strength, foundation and training of cutting-edge personnel, should they highlight their own characteristics, comply with the requirements of the times, and quickly respond to the real market, so as to design the discipline proportion more reasonably. Just think: if such talents are not cultivated in Colleges and universities, do we have to turn around and rely on the efforts of technical secondary schools or technical schools? It is precisely from these starting points that we can better complete the comprehensive three-dimensional printing talent training task

therefore, it is obvious that domestic market development, continuous renewal of ideas, and abundant talent supply are the "first three axes" to achieve a leap in color management. Therefore, the key to producing a good one is to link the good and bad local cleavage. Although it will not shake the direction of the printing industry, it will have a far-reaching impact on the time spent in the whole process

of course, even if everything goes well, this process may still be relatively long, because it takes time to update ideas and cultivate more people. After the new generation of printers enter the society, they can only start from the good application of large powerful manufacturers from point to area, and then promote it. Fortunately, the final effect of color management in this process is beyond doubt, because the path taken by developed countries has fully proved its importance and great significance for printing. "Only when advantages appear can talents emerge" is the core concept of social development. With the continuous progress of society, the advantages of this technology will become increasingly prominent. Now our only question is: who can be one step faster to master this technology and win a broader future
