Stereoscopic printing, eyeball market

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, the three-dimensional printing of three-dimensional objects to reproduce three-dimensional images of objects has become an important part of the special printing industry. Effect. These plastic cards are three-dimensional prints. Today, printers are using lenticular lens printing processes to obtain more complex products, ranging from labels, poster posters to packaging products, and even plastic cups. Although we do not see stereoscopic visual effects in the true sense, but only visual deception, the broad prospects for three-dimensional printing cannot be ignored.

"Eyeball" on the market

The principle of three-dimensional printing is to simulate the distance between two eyes, and shoot from different angles. The left and right pixels are recorded on the photosensitive material. When viewed, the left pixel 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. Three-dimensional printing can realistically reproduce objects with a strong sense of three-dimensionality. Product images are clear, rich layers, vivid image, profound artistic conception; three-dimensional printing manuscripts are often made of design or scenery, and the printed matter is generally selected for high-quality coated paper and high-temperature ink printing, so the gloss is good, bright colors, It is not easy to fade; the surface of the printed product is covered with a convex-convex mirror-like grating plate, and the three-dimensional effect of the panoramic picture can be directly viewed. From a physiological point of view, binocular parallax is the fundamental factor for people to obtain stereo vision. In everyday life, when people observe objects, the images of the objects seen by the left and right eyes will differ due to the perspective between the two eyes. , which is parallax, it gives people three-dimensionality.

Stereoscopic printing originates from three-dimensional image negatives. It adopts traditional optical principles of production and synthesis in photography and production, which imposes a great limitation on the application of three-dimensional photographs. Due to the expensive production equipment and complex operation of process technology, Due to high production costs and other reasons, three-dimensional printing cannot be promoted and popularized. Therefore, three-dimensional printing is also subject to unsatisfactory results such as long process flow in the pre-printing process, large accumulated errors between processes, reduced screen definition, and influencing the printing effect. 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 perfected and stabilized. Therefore, three-dimensional printing entered a new era, the digital era. The three-dimensional multi-image synthesis uses computer software and computer-to-plate (CTP) technology. After adopting the CTP plate-making equipment, the quality of the printing plate has been greatly improved. It is possible to accurately replicate fine dots and rich color levels. The CTP plate-making equipment is also convenient. Using FM screening and local screening. Thanks to the popularization of Heidelberg presses, the three-dimensional printing quality has undergone a qualitative leap, and it can be used on a large scale for commercial printing and packaging printing. Today, the range of three-dimensional printing applications is further expanded. The technology is used in packaging and decoration products, commercial advertising, science and education cartoons, postcards, New Year's cards, security labels, trademark tags, mouse trays, and various types of credit cards. The development time of three-dimensional printing in China is not short, but because it has not found a suitable market position, 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 distinctive “Chinese characteristics”. The business opportunities in the Chinese three-dimensional printing market are unlimited.

Soldiers and horses did not move, "technology" first

Technology needs innovation. 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, the three-dimensional printing companies in China generally lack the spirit of innovation. One is the lack of technological innovation; the other is the lack of product innovation. Many domestic printers lack understanding of new product development. As long as they have a job, they will not actively seek technological breakthroughs. They rarely work hard to develop new products. However, in foreign countries, printing methods such as fragrances and foamed gratings, which are still rare in China, have long been used in stereoscopic printing. In today's increasingly digitalized printing industry, three-dimensional printing companies should apply the latest technology to the field of three-dimensional printing, and they should dare to explore it. Only in this way can there be great development.

Technically, 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 stereoscopic printing. It can be said that professional software entering the market is also a major breakthrough in stereoscopic printing technology. It has become more convenient to convert ordinary pictures into manuscripts for three-dimensional printing. Some large-scale three-dimensional printing companies in China have begun to use them. Although there have been many professional production software, but overall, ordinary image software (such as Photoshop, etc.) is still very popular with three-dimensional printing companies. As for the reason why they do not want to use professional software, some professionals are unwilling to try because they fear that the software will not come from practice. The price factor also makes many of the three-dimensional printing companies, which have long been familiar with the application of common image software, are reluctant to switch to expensive professional software.

The innovation of printing equipment promotes the progress of three-dimensional printing. As the use 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 Ryobi have all introduced offset presses with this capability. The innovation of offset printing equipment has greatly promoted the development of three-dimensional printing, and printing can be realized directly on the raster. As a result, the production efficiency of three-dimensional printing has been greatly improved, and the accuracy of the product has been sufficiently ensured.

A variety of techniques coexist. At present, the level of three-dimensional printing production in China is uneven and various processes are adopted. The situation of three-dimensional printing companies is different, and the processes adopted are also different. However, the two main methods described above are mainly the direct printing on the raster and the printing on the paper and pasting on the grating, or pasting onto the plastic film and then pressing out the grating.

Increased environmental awareness. Regardless of whether it is used for stationery or food packaging or children's toys, the requirements for environmental protection should not be ignored. At present, the European and American markets already have relevant laws and regulations in these fields, and our country is constantly improving in this respect. If we still do not pay attention to environmental protection, we will inevitably restrict the domestic printing companies from accepting foreign orders. Environmental issues are almost all consumables in stereo printing, including grating materials, inks, papers, adhesives, and so on. To be non-toxic and harmless, you must choose superior materials, which increases the cost of production. Fortunately, most of the three-dimensional printing companies now recognize this trend, work on materials, and do environmental protection products to retain more business.

One-man show

There are many three-dimensional printing companies in Guangdong, Shanghai, and Jiangsu and Zhejiang. Many of these companies are joint ventures or wholly foreign-owned enterprises. In terms of business sources, especially for companies with a certain scale, foreign orders are the pillar businesses of the company. Obviously, for foreign companies or joint ventures, foreign exchange orders have their unique advantages. Such enterprises can easily rely on the resources of one foreign party to manage their external orders. At present, the application of three-dimensional printing in foreign countries is more extensive and the market is relatively mature. Many foreign companies have taken a fancy to the advantages of cheap labor and low production costs in China, and sent the three-dimensional printing business to China to greatly reduce production costs. . Generally speaking, the requirements for foreign orders are high, and the used materials such as grating materials and inks need to be imported. Even so, domestic three-dimensional printing companies can still bring a lot of benefits to foreign customers.

Some stereoscopic printing companies do not have their own printing equipment. After producing the film, they need to get other printing companies to print out the finished or semi-finished products. If they need to be pressed or die-cut, they will be brought back to press or die-cut. . Such a phenomenon of printing by "machine" is not accidental, but it is a common phenomenon in the field of three-dimensional printing. The reason is nothing more than the expensive printing equipment. The three-dimensional printing requires high precision. It is not the thicker coated paper that is printed on the machine or the cardboard is a thicker grating. The requirements for the performance of the printing press are very high, and the damage to the printing equipment is more serious. Generally, only some imported equipment is required. To be competent. However, the purchase cost of these imported equipment is extremely high, and most domestic three-dimensional printing companies have chosen to use "machine" printing in such a way.

At the same time, we should also see that stereoscopic printing also has a large market in China. In addition, the prepress technology and printing of stereoscopic printing are almost the same as ordinary printing, and ordinary printing plants can use it as a new investment project. Currently, While the cost of three-dimensional printing has been accepted by most printing companies, ordinary printing companies can increase their profits through this new investment project. In contrast, three-dimensional printing is easier to obtain profit than traditional printing.

Expand new space

Three-dimensional products are three-dimensional, animated, and three-dimensional maps, and the resulting changes are completely different from traditional flat printing. Because of its exquisite and novel features, three-dimensional products easily caught people's attention and impressed customers who were pursuing new vitality. These features can increase the added value of products, become an excellent means for customers to promote goods and improve market image, and novel advertising media. This kind of product has been popular in Europe and America for many years and has a great demand. At present, there are many kinds of three-dimensional printing application fields that can be developed on the market. Expanding the application of three-dimensional printing is also an important part of the development of three-dimensional printing.

Three-dimensional animation. Three-dimensional animation can be obtained through changing observation angles to obtain dynamic images. If the printed three-dimensional prints are called three-dimensional space prints, then the dynamic factors can be added to combine the three-dimensional sense and the animation to produce a new one. Four-dimensional space print. This stereoscopic print is more novel and has many applications at present.

Large format advertising. Three-dimensional printed lightbox advertisements are not common now, but many attempts have already been made. Because large-format advertising printing has high requirements for gratings, inks, etc., this application is not much in China, mainly because the production cost is too high. However, many people in the industry are still very optimistic about this application, because now the light box advertising market is fierce, advertisers must come up with some new and more attractive form of expression to attract customers. At present, the three-dimensional printing form is the best, and does not require expensive investment. As long as the technology is strictly controlled, it can produce beautiful three-dimensional prints. Therefore, in the near future, such a new form of promotional media will surely be favored by advertisers.

Anti-counterfeiting features. The imaging technology of three-dimensional printing itself is equivalent to using the optical encryption anti-counterfeiting method, and can not be copied as simple as ordinary prints. This technology can be applied to the anti-counterfeit labels of tobacco, alcohol, beverages, cosmetics, clothing, and medicines. Some experts boldly predicted that in the near future, three-dimensional printing trademarks will inevitably become the main anti-counterfeiting methods.

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 also constantly exploring and updating, improving the technological 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 companies are engaged in the development and research of three-dimensional printing technology, and use computer and other scientific and technological means to creatively develop new three-dimensional printing technologies. Three-dimensional printing equipment and three-dimensional printing products have been fully introduced to the market. This is a major innovation in the field of printing, and it is also an inevitable trend in the printing field. China's use of three-dimensional printing equipment production and production of three-dimensional graphics, three-dimensional anti-counterfeit trademark logo, three-dimensional rainbow materials, and other comprehensive
