Development trend of proofing market - digital proofing has become the best alternative to traditional proofing.
at present, with the rise of CTP (computer to plate computer direct plate making) wave in the global printing industry, the digital printing era has come, and CTP technology has become an inevitable development trend of prepress industry. In recent years, great changes have taken place in the printing service market. The increasing number of work orders in the market, the reduction of the number of prints per order, and the shortening of printing time require that the traditional proofing methods face more severe challenges. The traditional lengthy Proofing processes such as film making and sample drying are difficult to meet the increasing printing needs of modern times. Manual operation and chemical proofing are not only time-consuming and expensive, but also the printing color is in an unstable state. The actual printing and printing colors often differ greatly. How to print the most documents in the shortest time? How to use the most advanced technology or method to improve or replace the traditional proofing? Digital proofing, a new best solution to replace traditional proofing, has attracted more and more attention. Digital proofing: it is inevitable to replace traditional proofing. What is digital proofing? Compared with traditional proofing, what are the advantages of digital proofing? What is the difference between them? As we know, digital proofing came after the emergence of large-scale electronic composition systems. With the growing maturity of image digitization technology, proofing also began to develop in the direction of digital. The so-called digital proofing is a kind of proofing technology that directly outputs the electronic manuscript after digital processing in electronic publishing. It directly refers to the output proofing of the force value at the moment when the sample is completely broken and separated by using a large format printer in digital mode, and replaces the traditional lengthy Proofing processes such as film making and sample drying. Compared with traditional proofing, digital proofing has the following advantages: first, in terms of quality effect, it mainly depends on the stability of color and the reliability of objective analysis. Because traditional proofing uses manual inking and pressure adjustment, the effect is very unstable. If the same set of films are proofed separately, the printing effect is often different. Digital proofing is automatic imaging and can be very stable. Of course, if the equipment is of poor quality, such as the ink head is often blocked, it will also cause unstable factors. Traditional proofing is reliable because it uses the same film as printing. If digital proofing can use the same set of data processed by RIP for proofing and plate making, it will be more reliable. Because in the whole process, except for human factors, the most likely difference in operation is rip operation. Secondly, in terms of cost-effectiveness, it mainly depends on the investment cost and income. In this respect, the traditional proofing is inferior to the digital proofing. Because if two sets of folio four-color proofing are completed within one hour based on the same production capacity, the investment in traditional equipment requires four sets of typewriters, supporting plate printing and printing equipment, plus the required staff and large factory buildings, the investment amount is about 2million yuan. The investment in digital proofing will not exceed 1.5 million yuan at most, and the additional labor is close to zero. In general, the return on investment of digital proofing can be much higher than that of traditional proofing. Finally, in terms of efficiency performance, it mainly depends on production speed, multiple simulation capabilities and multiple format capabilities. The imaging speed of digital proofing is fast. Ordinary printers on the market can complete a high-quality folio layout within 20 minutes, while traditional proofing generally takes 30-40 minutes. The color gamut expressed by most digital proofing machines (that is, the full range of colors that can be expressed by a device) is richer than that of ink. The rich color gamut and good color management software enable digital proofing to simulate not only the effect of printed matter, but also other production effects, such as silk printing, digital printing, inkjet posters, and even the performance under high-speed rotary printing machines, It can better meet the needs of increasingly diversified output in the market. The complete digital proofing system can not only simulate the color effect of an output medium, but also automatically adjust the color of the image in the file according to the needs of different outputs, so that the operator does not need to modify it, and truly achieve an automated workflow. All these can not be done by traditional proofing. Common tools supporting digital proofing although digital proofing has many advantages, it is inseparable from specific software and hardware support. With the rapid development of digital printing technology, major companies have launched their own technologies and equipment to meet the needs of different environments, especially the large format printer products necessary for digital proofing. In the domestic printer market, there are many types of printers available, but there are not many products that really meet the unique needs of the digital proofing business. This is because printing should not only achieve high speed, but also ensure the high quality of the output picture, and achieve the organic unity of speed and quality. In the current large format printer market, the most typical is HP Designjet 5000 large format printer series of HP company. In terms of speed, thanks to the more advanced jet ex, he added that press technology (the number of nozzles on each print head reached 512) and the revolutionary 25mm wide print head were the first professional large format printer with production speed. In terms of color, this series of printers adopt six color ink (cmykcm) and color layering technology to realize real and practical six color ink printing and 1200dpi printing. This comprehensive and substantial improvement in speed and quality has broken the "inertia law" that the speed and quality of large format printing can not be improved at the same time for a long time, and realized the real "speed and quality" omnipotence. In terms of software, it is necessary to mention RIP software, which is only about 60% of the current comprehensive self-sufficiency rate in China's new chemical materials market. Now there are many RIP software on the market, but few can be customized to achieve digital. Now take the "easy proofing rip" software of Jinhao electronic systems Co., Ltd. as an example. This software is an OEM product of harlequin rip based on postscript language level 3 standard, with built-in ICC Color management system, Ensure that the digital proofing sample realizes the true reproduction of printing ink color simulation. Therefore, before choosing a digital proofing system, you should clarify your requirements, and then choose a digital proofing system of different levels or prices. Application prospect of digital proofing with the advent of the era of computer plate making and the development of related equipment, digital proofing will further threaten the status of traditional proofing. Because the digital proofing scheme eliminates the influence of human and other external factors, it greatly improves the stability of proofing output; And greatly shorten the proofing process; At the same time, because the proofing works can be modified digitally, the proofing cost is greatly reduced. This scheme has successfully solved many problems in the traditional proofing, such as long production cycle, unstable proofing, high cost and so on, and triggered a new revolution in the printing field. At present, digital proofing has been widely used in the United States, Japan and other developed countries. However, due to the limitations of many conditions, digital proofing has not been fully popularized in China. However, some users have begun to use digital proofing, and they pursue speed, stability and cost-effectiveness. Especially for high-end users, although the above three advantages can not fully meet them, color quality is their most important requirement. It is precisely because of the strict requirements of these users that digital proofing, as a new technology, is gradually popularized, which is of great significance to improve prepress efficiency and customer satisfaction. It can be said that digital proofing has a broad market application prospect. There will be more and more cases of using digital proofing instead of traditional proofing, especially in the publishing and advertising industries, where the demand for digital proofing will be greater. Therefore, digital proofing instead of traditional proofing will become a new development trend of proofing market
