In the current printing industry, I am afraid that the "digital" is the most talked about. No matter whether it is a domestic or foreign professional journal, the numbers are reserved for each period. Now a complete printing company will not be separated from the digital existence, like the color desktop publishing technology, the operation control system on the printing machine wait has been the basic technology of modern printing. Recently, digital printing, CTP technology, digital asset management, cross-media publishing, etc. have continued to emerge. It can be said that, in all traditional industries, no industry can absorb advanced digital technologies faster than the printing industry and integrate more quickly. To the information technology, this phenomenon and the printing industry are also related to the information industry.
Although information technology has been used on a large scale in the printing industry, no one company can justify their digitalization. Just as each unit has a computer, each computer configuration is very high, but these machines are used to do database management or just manuscript input, the informationization of the program is very different. In addition, the digitalization of the printing industry is also a rather vague concept. Under the current technology and conditions, how can we keep up with the trend of digitalization? Most printing companies still do not have a specific concept. As for planning, there is no way to talk about it. Now. Let us take a look at the degree to which the digitalization of the printing industry can be achieved.
Digital printing equipment
Not too long ago, we could also see that some of the records of the album “made entirely by the use of a color desktop publishing system†attracted the interest of some readers and thought that this was a better place than other magazines, and it was not known that the DIP technology was earlier than the end of the 1980s. It began to be implemented in the printing industry. This bid farewell to "lead-and-fire" and ushered in the "optical and electrical" pre-press technology revolution - the emergence of a fundamental change in the pattern of pre-press production. Since DPT production is particularly convenient and time-saving, it is more than sufficient for a person to produce a magazine, and the investment is lower than with simulation. Almost all prepress production units have invested in this new technology. The pre-press department that does not use this technology is probably only printing some special requirements such as printing money.
The computer-to-plate (CTP) process that continued with the DTP revolution is a new wave of digitization. Imagine if a device could replace a laser image-setter, a developer, a plate-making machine, eliminate a film, and save the imposition, a few people would be able to complete the work that would have previously been done by dozens of people, and would be very competitive. At present, CTP has been better promoted in newspaper printing, but commercial printing has not been satisfactory. This is related to the fact that the overall domestic environment has not yet reached the level of matching. The first is that CTP plates can be produced by the second rubber plant except for the others. The rest are imported, and the price is high. Second, the overall production process (including digital proofing, digital asset management, etc.) is not supported, and we must give full play to the production capacity of CTP. The entire process should be quantified and integrated. Unfortunately, domestic printing companies have first-class production equipment, but they are far from the foreign companies in software construction. This is similar to the love relationship in Taiwan. Taiwan had more than 60 CTPs in 2001, but only one or two made money. Except for the fact that buyers of CTP equipment are almost all commercial printers, the production process is not matched and CTP is not used. Production capacity is also an important reason.
Looking further ahead, digital printing can almost replace the CTP process. Not long ago, the world's major printing press manufacturer Heidelberg expects that the digital printing business will be as much as the offset printing business after 7 years. Digital printing has advantages that other printing cannot match in on-demand printing, variable data printing, distribution, etc. It solves the problems of fast turnaround time, different printing versions, customized content, and personalization.
For example, variable data printing, which cannot be solved in conventional printing, can be easily implemented in digital printing, and the image or text on each page can continuously change in one printing. In addition, on-demand printing is suitable for publications that require frequent updates and prints with many pictures inserted, such as slightly modified manuals, meeting documents, charts, and so on.
The digital presses currently dominated by Xerox DocuTech already accounted for 85% of the on-demand print jobs previously produced on compact presses and copiers in the United States, and this trend is beginning to shift to color digital presses. Digital printing technology also ensures that the reprinted print has the same effect as the first edition. A single document can be printed simultaneously in several locations. This will reduce storage and shipping costs. For example, a company can create a new product catalogue at the headquarters. , And then send the documents to the local branch offices can be printed locally.
However, digital printing still encounters many problems. Expensive prices and incomplete technology have made many printing companies daunted. This is one of the main reasons why digital printing has lagged behind CTP. Although digital printing equipment has become a hot topic in recent years, most of them are still in the experimental and trial phase. Although digital presses that can be put into production have been on the market for a long time, by the end of 2000, the number of installations in the world had not exceeded 1,500. However, many experts are optimistic that some of the new digital printing devices introduced in the near future will push digital printing faster.
Digital production process
The digitalization of production processes is the most concerned part of the current foreign printing community.
The CIP3 Association is an international collaboration organization consisting of nearly 40 major companies in the printing, publishing and paper processing industries. It encompasses almost all the famous businesses in the printing industry. CIP3 covers the entire printing process and specifies a standard format for machine-readable information. These formats allow all machines to read and understand data regardless of platform or source. Its goal is to form a truly open and independent printing production environment. All work-related data is input at one time and in different ways by different professionals in a uniquely understandable format and then output as a whole. The goal of CIP3 is to replace the currently isolated control system with complete terminal-to-terminal automation. This can lead to fewer errors, faster cycles, tighter cost controls, and more accurate knowledge of what is happening in the factory.
Now the CIP3 association and the JDF association have merged into the CIP4 association. The future goal of the association is to achieve complete automation before printing, printing, and postpress. For example, after-printing binding equipment is provided in the format of the Print Production Format (PPF) according to the prepress process. The information can be processed directly. In addition, adjusting and setting up the production process, managing customers and production data, and importing the Internet according to orders and production conditions are the goals of the association.
Color management is another important part of the digital process of printing. There are many factors that cause color deviation in printing, and the big difference between the final printing product and the customer's expectations has always been a problem that has plagued the printing industry.
In order to deal with the problem of color more conveniently, the color management system (Color Manage System) came into being. This is the concept proposed by Kodak Company. The ICC color profile is the main axis. Through the device's color gamut description file, the actual color gamut of the text output is standardized. When different devices use the same color gamut management file, the color management system will coordinate their work in the common color gamut space and use the same color in overlapping gamuts as much as possible, although this will still cause some color information to be lost. The color management system is still the best color solution at present.
However, many experts believe that the core of the digital process is in cross-media publishing and unified collaboration.
The HTML that is usually used for web page production is to extract content from the tag, so that readers can see that the content of the XML that the author wants to express retains the skeleton and content of the tag. HTML can be used as an XML web page output module, and XML and different modules constitute different database processing systems. Today's World-Wide-Web is nothing more than an information network. XML can put a messy, improvised HTML data on the Internet and put a data structure on it, attach the global information network to the label and Defined as a World-Wide-Database. XML will eventually realize the interaction between all computers, database exchange and so on.
Thanks to XML tags and custom features, cross-media publishing is possible. Just like building an XML library, first build a library (the library is the DAM digital asset management) management module. This module is used to search for all the book's title tags, or author tags, and then from the content tag. Give the entire book. If you have a PDF module, you get a PDF eBook.
Imagine a newspaper's asset management system using XML as the data format in the workflow. The journalist sends the data in XML format to the database. The editor uses the editing module to find the desired article using the group tab via the “Summary†tab. Modules make layouts, while site editors use the same editing module to edit and then use HTML modules to create web pages. Different applications of the same data (re-purpose) can be achieved. The domestic Founder company has been committed to the development of digital asset management, and its cross-media publishing system has been used.
