In the 1990s, image technology entered the era of three-dimensional photo, and human visual experience entered a three-dimensional field. In the field of printing, three-dimensional reproduction of stereoscopic image printing of objects - three-dimensional printing, has become an important content in the special printing industry, such as some of our cute little cards, tilting cards or moving cards before and after will see all kinds of wonderful Effect. These plastic cards are three-dimensional prints. Today, printers are using raster lens printing to acquire more complex products, ranging from labels and posters to packaging products and even plastic cups. Although we are not seeing the stereoscopic effect in the true sense, it is only a visual deception, but the broad development prospects of three-dimensional printing cannot be ignored.
Market on the "eyeball"
The principle of three-dimensional printing is to simulate the distance between two eyes of a person. When shooting from different angles, the left and right pixels are recorded on the photosensitive material. When viewing, the left eye sees the left pixel and the right eye sees the right pixel. The printed matter produced according to this principle is For three-dimensional printing products. Stereoscopic printing can reproduce objects realistically and has a strong three-dimensional effect. The product image is clear, the layer is rich, the image is realistic, and the artistic conception is deep; the original of the three-dimensional printing is often formed by the design or the scene, and the printed matter is generally selected as high-quality coated paper and high-temperature ink printing, so the gloss is good and the color is bright. It is not easy to fade; the surface of the printed product is covered with a lenticular lenticular grating plate, which can directly view the stereoscopic effect of the panoramic image. From the physiological point of view, the parallax of the two eyes is the fundamental factor for people to obtain stereoscopic vision. In daily life, when people observe an object, the image of the object seen by the left and right eyes will be different due to the angle of view between the two eyes. , that is, parallax, it gives people a three-dimensional sense.
The three-dimensional printing is derived from the three-dimensional image negative film. It adopts the traditional optical principle of production and synthesis in shooting and production, which makes the stereo photo have great limitations in application, and because the production equipment is expensive, the process technology is complicated. Due to the high production cost and the like, stereoscopic printing cannot be promoted and popularized. Therefore, stereo printing is also subject to long process flow in the prepress printing process, large cumulative error between processes, reduced image sharpness, and adverse effects such as printing effects. influences.
In the 1980s, due to the development of digital technology, the development of three-dimensional printing was promoted, and the production technology was increasingly perfect and stable. Three-dimensional printing thus entered a new era, the digital age. The three-dimensional multi-image synthesis uses computer software and computer direct plate making (CTP) technology. After using CTP plate making equipment, the quality of the printing plate has been greatly improved, and the fine mesh points and rich color levels can be accurately reproduced, and the CTP plate making equipment is also convenient. FM network and local screening are used. Moreover, due to the popularity of Heidelberg printing presses, the quality of three-dimensional printing has made a qualitative leap, and it can be used for commercial printing and packaging printing on a large scale. Nowadays, the application range of three-dimensional printing has been further expanded. The technology is applied to packaging and decoration products, commercial advertisements, science and education cartoons, postcards, Chinese New Year films, anti-counterfeiting marks, trademark tags, mouse trays, and various credit cards. The development time of three-dimensional printing in China is not short, but since it has not found a suitable market positioning, the application is not very extensive. However, with the development of related technologies and the growth of market demand, the domestic three-dimensional printing industry is developing rapidly and has formed a distinct "Chinese characteristic". The business opportunities in China's three-dimensional printing market are unlimited.
The soldiers and horses have not moved, "technology" first
Technology needs to be innovated. In recent years, the domestic three-dimensional printing market has been greatly developed and a number of well-known enterprises have emerged. However, on the whole, domestic three-dimensional printing enterprises generally lack innovation spirit. First, lack of technological innovation; first, lack of product innovation. Many domestic printing companies have insufficient understanding of new product development. As long as they have a job at hand, they will not actively seek technical breakthroughs, and rarely work hard to develop new products. Different from foreign countries, the printing methods such as fragrance and foaming grating which are rare in China have already been widely used in three-dimensional printing. Today, printing companies are becoming more and more digital. Stereo printing companies should apply the latest technology to the field of three-dimensional printing. They should dare to explore, so that there will be great development.
In terms of technology, professional software enters and popular image software is popular. Nowadays, related software for three-dimensional printing has been continuously introduced and has already entered the Chinese market. Professional software such as 3D4U has been well known in the field of three-dimensional printing. It can be said that the entry of professional software into the market is also a major breakthrough in the three-dimensional printing technology, and it becomes more convenient to convert ordinary pictures into three-dimensional printed originals. Some large-scale three-dimensional printing enterprises in China have already begun to use. Although there have been many professional production software, in general, ordinary image software (such as Photoshop, etc.) is still very popular among three-dimensional printing companies. As for the reason for not being willing to use professional software, some professionals are not willing to try because they are worried that the software is not from practice. The price factor has also made many stereoscopic printing companies, which have long been familiar with the application of ordinary image software, reluctant to switch to expensive professional software.
The innovation of printing equipment has promoted the advancement of three-dimensional printing. As the application of UV technology continues to mature, many equipment manufacturers have introduced various types of UV offset presses. At the same time, printing plastic sheets with offset presses is no longer a problem. Heidelberg, Manroland, KBA, Komori, and Liyoubi have already launched offset presses with this function. The innovation of offset printing equipment has greatly promoted the development of three-dimensional printing, and the printing on the grating is realized directly. Thereby, the production efficiency of the three-dimensional printing is greatly improved, and the product precision is sufficiently guaranteed.
A variety of processes coexist. At present, the level of three-dimensional printing production in China is uneven, and various processes are used. The situation of three-dimensional printing enterprises is different, and the processes adopted are also different. However, it is mainly the two methods described in the previous section, that is, printing directly on the grating and printing on the paper first and then pasting on the grating, or pasting on the plastic film and then pressing out the grating.
Environmental awareness is strengthened. Stereoscopic printing, whether used on stationery or in food packaging or children's toys, should not be ignored. At present, the European and American markets have already had relevant laws and regulations in these fields, and China is constantly improving in this respect. If you still do not pay attention to environmental protection, it will inevitably limit domestic printing companies to accept foreign orders to a certain extent. Environmental issues almost all of the consumables in stereo printing, including grating materials, inks, paper, adhesives, and more. To be non-toxic and harmless, you must choose the best materials, which increases the production cost. Fortunately, most of today's three-dimensional printing companies have recognized this trend, working on materials and making environmentally friendly products to retain more business.
One-man show of the foreign single
Three-dimensional printing companies are mostly in Guangdong, Shanghai and Jiangsu and Zhejiang provinces. Many of these companies are joint ventures or wholly foreign-owned enterprises. In terms of business sources, especially for companies with a certain size, the foreign orders are the pillar business of the enterprise. Obviously, for foreign companies or joint ventures, the foreign orders have their unique advantages. Such enterprises can easily rely on the resources of foreign investors to operate foreign orders. At present, foreign countries have more extensive applications for three-dimensional printing, and the market is relatively mature. Many foreign companies have taken advantage of China's cheap labor and low production costs, and sent three-dimensional printing business to China to greatly reduce production costs. . Generally, the requirements for external orders are relatively high, and the materials used for grating materials and inks need to be imported. Even so, domestic three-dimensional printing enterprises can still bring many benefits to foreign customers.
Some three-dimensional printing companies do not have their own printing equipment. After making the film, they need to get other printing factories to print the finished or semi-finished products. If they need to press or die-cut, then take back the press or die-cut. . Such a phenomenon of "machine" printing is not accidental, but a phenomenon that is common in the field of three-dimensional printing. The reason is nothing more than the expensive printing equipment. The accuracy of three-dimensional printing is high. The thicker coated paper or cardboard is a thicker grating. The performance requirements of the printing press are very high, and the damage to the printing equipment is serious. Generally, there are only some imported equipment. Can be competent. However, the cost of purchasing these imported equipment is extremely high, and most domestic three-dimensional printing companies have chosen to use "machine" printing.
At the same time, we should also see that three-dimensional printing also has a large market in China. In addition, the prepress technology and printing of three-dimensional printing are almost the same as ordinary printing. Ordinary printing companies can use it as a new investment project. Currently, In the case that the cost of three-dimensional printing has been accepted by most printers, ordinary printing companies can increase their profits through this new investment project. Relatively speaking, stereo printing is more profitable than traditional printing.
Expand new space
The three-dimensional products have three kinds of three-dimensional, animated, and different-variation pictures, and the resulting change effect is completely different from the traditional flat printing. Stereoscopic products easily capture people's attention because of their exquisite and novel features, and they are impressed by those who pursue new vitality. These special features enhance the added value of products, become an excellent means for customers to promote goods and improve the market image and novel advertising media. This product has been popular in Europe and America for many years, and the demand is very large. There are a variety of three-dimensional printing applications that can be developed on the market. Expanding the application field of three-dimensional printing is also an important part of developing three-dimensional printing.
Three-dimensional cartoon. The stereoscopic animation can obtain a dynamic picture by changing the viewing angle. If the printed three-dimensional print is called a three-dimensional space print, and then the dynamic factors are added, the three-dimensional sense and the animation can be combined to produce a new one. Four-dimensional space prints. This kind of three-dimensional print is more novel and has many applications.
Large format advertising. Stereo-printed lightbox ads are not common now, but there have been many attempts. Due to the high requirements for large-format advertising printing on gratings and inks, this application is not much in China, mainly due to the high production cost. However, many people in the industry are still very optimistic about this application, because now the competition in the light box advertising market is fierce, advertisers must come up with some novel and more tempting expressions to attract customers. At present, the three-dimensional printing is the best form of expression, and does not require expensive costs. As long as it is technically strictly controlled, it can produce beautiful three-dimensional prints. Therefore, in the near future, such an updated form of publicity media will certainly be favored by advertisers.
Anti-counterfeiting function. The imaging technology of the three-dimensional printing itself is equivalent to the optical encryption anti-counterfeiting method, and can not be as simple as the ordinary printed matter, and can be applied to the anti-counterfeiting label of tobacco, alcohol, beverage, cosmetics, clothing, medicine and the like. Some experts have boldly predicted that in the near future, three-dimensional printing trademarks will inevitably become the main anti-counterfeiting method.
For three-dimensional printing, its added value is several times higher than that of flat printing, and the market prospect is broad. At the same time, the three-dimensional printing technology is constantly exploring and updating the process, and its purpose is to enable the three-dimensional printing to be effectively developed in the printing industry in China. In China, many printing manufacturers are engaged in the development and research of three-dimensional printing technology, using computer and other scientific and technological means to creatively develop new three-dimensional printing technology. Three-dimensional printing equipment and three-dimensional printing products have been fully introduced to the market, which is a major innovation in the field of printing, and is also an inevitable development trend in the printing field. China's three-dimensional printing equipment produced by three-dimensional printing equipment, three-dimensional anti-counterfeit trademark logo, three-dimensional rainbow materials and other comprehensive products, its stereoscopic image effect has reached the world's leading level. The three-dimensional printed products are novel, beautiful, realistic and multi-layered. The three-dimensional picture is deeply loved by people. It is a high-tech project with wide application, rich profits and broad prospects.
