3D printing In the 1990s, video technology entered the era of three-dimensional photo, and human visual experience entered a three-dimensional field. Three-dimensional printing is the development of three-dimensional photography and the crystallization of the exploration of three-dimensional display technology. It simulates the distance between human eyes, shoots from different angles, records the left and right pixels on the photosensitive material, the left pixel sees the right pixel, and the right eye sees the left pixel. The printing production process based on this principle is generally called stereo printing. Three-dimensional printing equipment and three-dimensional printing products are fully marketed, which is a major innovation in the printing field and an inevitable development trend in the printing field. With the use of three-dimensional printing equipment, we have been able to produce all-round products such as three-dimensional graphics, three-dimensional anti-counterfeiting signs, and three-dimensional rainbow materials. The three-dimensional anti-counterfeit signs have wonderful characteristics, and the three-dimensional rainbow materials have a colorful world. At present, three-dimensional printing is widely used in enterprise product packaging and decoration, trademark logo anti-counterfeiting, merchandise advertising pictures, advertising posters, art decoration, museum exhibition window display panels, cultural landscape. Natural scenery pictures, cultural goods, tourist souvenirs, commemorative tickets, postcards, various greeting cards, business cards, signs, etc., in the field of flat printing, three-dimensional printing can be involved. The three-dimensional printed products are novel and beautiful, with realistic shapes and multi-layered three-dimensional pictures, which are deeply loved by people. UV printing UV printing refers to printing with UV ink, which is widely used in offset printing, screen printing and flexo printing. UV curing is a key technology in UV printing. Industrial application of UV curing technology began in the 1960s, the German wood company used it for curing the coating layer on the wood surface. The world's first use of UV lithography was in the United States, and the British company was successfully used in 1970. Compared with traditional lithography, UV printing is a young and new technology, but it has become a very important printing technology. Generally speaking, UV curing is to irradiate a photosensitive compound (ink) with a UV light source, so that the "photoinitiator" contained in the compound is stimulated by UV light, and it is used in a very short time (less than 1 second). The "Polymer" contained therein produces the "Radiation Curing Technology" for glue curing. On the national display, it is also classified as "Electronic Beam Curing" (Electronic Beam Curing), which is collectively called UV / EBCuring. Lithographic UV printing is based on the structure of lithographic printing, using UV ink and UV light source. Of course, it needs some very important matching conditions to complete. In addition to printing, UV varnishing for printing on transparent plastic film materials is also one of the varnishing methods widely used in the market. JDF JDF is the abbreviation of Job Definition Format. JDF is not a product, but a data format. It was initiated and developed by Adobe, Agfa, Heidelberg and Man Roland, and it plays an important role in the digital workflow. JDF is aimed at all printing fields including e-commerce in the printing industry and information management systems in the printing industry. JDF has become one of the core contents of the CIP4 standard and accepts the control of the CIP4 organization. Two design goals of JDF include: First, it is used to exchange information between different applications or systems serving a complete printing job; Second, facing the entire graphic field, including: consumables, design, graphic creativity. Print on demand and e-commerce for various processes. JDF is an XML-based data exchange format, which has the advantage of XML format-scalability, so JDF is highly extensible and can adapt to new requirements in the future. JDF can be flexibly adjusted according to each user's process. Because JDF is a vendor-independent standard, it is beneficial for vendors to develop their own related applications. It provides users with a comprehensive and flexible solution that can connect isolated systems in printing work to serve complete user operations. Bio-ink American scientists have long been working on a protein molecule called bacteriorhodopsin: illuminating its protein can trigger a photochemical reaction circle. Its principle: the photochemical reaction circle transports protons along the channel around the cell membrane. The purple color of this cell membrane is derived from the bacteriorhodopsin component called "retina". The amino acid in the cell membrane channel is firmly bound to the "retina". The "retina" in the dissolved state does not bind to amino acids and is pale yellow. Two sets of lasers with different wavelengths are used to irradiate this protein molecule alternately, so that the protein molecule can be converted between the purple structure and the yellow structure. It is this habit that inspired people's research and utilization of rhodopsin. The rhodopsin film can also change its color according to the conversion of an external electric field. In conventional bacteriorhodopsin, under the action of different electric fields, a low-contrast color change from purple to blue will be formed. However, the rhodopsin structure produced by a certain mutant bacteria will change from blue to light yellow under the action of a strong electric field. By sandwiching this protein film in a transparent plate combined with a large number of electrodes, a display plate can be made. Applying appropriate voltage to different parts of the film can "write" a page of a document or "place" an image on the display panel. Like the ink on paper, the image on the bacteriorhodopsin display can also be seen under ordinary light, and the protein film also provides the advantage of high contrast. Eicography Eicography is a plateless digital printing technology based on the principle of electrocoagulation. It is called the "next generation" printing technology by many people in the industry. It is an existing inkjet method and electrophotography in the field of on-demand printing. Technical supplements. Currently, prototypes using this technology are still under development. The research on "Eicography" began with A. Castegnier, a Canadian who was originally engaged in the development of photographs. In 1971, A. Castegnier used the air bubbles between the positive and negative electrodes due to the electrolysis reaction, thinking that the gelatin layer could form some kind of gravure inked hole, as long as the inked hole was filled with ink, it could be printed on ordinary paper (US Patent 3,752,746) . But in fact, the occurrence of bubbles can be stabilized, and the experiment cannot proceed smoothly as expected. However, A. Castegnier's research on this discovery did not stop there. Instead, Eicorsy was founded in 1981, and he devoted himself to related research and development. It was not until 1984 that A. Castegnier produced the basic idea of ​​Eicography, that is, the use of synthetic resin colloids to induce electrochemical aggregation between electrodes to form images (US Patent 4,555,320). Since then, Eicography has greatly improved printing speed, quality, and multicolor. At the NEXPO exhibition in June 1996, Eicorsy and Japan Toyo Ink Co. announced the technology of Eicography; at the 1998 IPEX exhibition, the Model 200 Eicography press was exhibited. This device can change the full-color variable data to 200 feet. The speed of 200dpi is used to produce 200dpi prints; at the DRUPA exhibition in 2000, they exhibited the Eico 400 Digital Press with a resolution of 400dpi, and the printing speed was 400 feet / minute. Currently, the two companies are still improving the Elco400. In the past printing process, the ink will not produce any chemical changes from the beginning to the end of the printing process; but in "Eicography", the ink uses the principle of electrochemical resin coagulation, according to the data signal and the current intensity between the positive and negative electrodes , Generate dots of corresponding size to form an image. The principle of electrocoagulation is based on the chemical reaction generated between the functional groups of the water-soluble resin and trivalent iron ions on the surface of the metal anode. The main features of "Eicography", which are still being further researched and improved, are as follows: First, the use of water-based inks has little environmental pollution. Second, the printing speed is high, which can reach 4 million feet per minute. Third, the resolution of 400dpi can be reached. Fourth, 256 steps can be reproduced during the printing process. EVA hot melt adhesive EVA hot melt adhesive is a solid meltable polymer that does not require solvents and does not contain moisture. The main components are composed of basic resin, tackifier, plasticizer, filler, antioxidant and viscosity adjustment. EVA hot melt adhesive is solid at room temperature, and the colloid after heating and melting is light brown translucent liquid. EVA hot melt adhesive is light brown with the following characteristics: First, the hot melt adhesive is 100% solid at room temperature. When heated to a certain temperature, it becomes a liquid, and once cooled to below the melting point, it quickly becomes a solid. It has a melting point of 800 ° C, a release point of 7-13 seconds, a solidification point of 7-14 seconds, and a cooling point of 2-3 minutes. Second, it has the characteristics of fast curing, low pollution and strong adhesion. The adhesive layer has both a certain flexibility and a certain hardness. Third, there is re-stickiness. After brushing and solidifying on the adherend, it can be reheated and melted, and then used again. Fourth, easy to use. As long as the EVA hot melt adhesive is heated and melted into a liquid, it can be painted on the adherend, and after being pressed and cooled for a few seconds, it can be fully cured. EVA series hot melt adhesive is green adhesive, non-toxic and solvent-free. Since its successful development in China in the 1970s, it has formed a series of products for packaging, positioning, speakers, book binding and refrigerator heat sealing. Products have been widely used in book binding, various types of packaging, appliance-free assembly and positioning of home appliances, cigarette packaging and filters, material compounding, hot melt glazing, etc. Free Flow digital workflow integration software The so-called digital work flow (Digital Workflow) refers to a set of processing programs composed of digital hardware and software, so that the product-by-product processing process is smooth and smooth from start to finish. In recent years, the printing industry has made some achievements in hardware construction, but there are still problems in how to make the software equipped with each hardware compatible with each other and form an open system. Therefore, people of insight in the industry put forward the concept of Free Flow digital workflow integration software. It refers to the integration of various software applications in the digital workflow into a software package with free flow and open features. The integrated software has industry-standard workflow technology and an open interface, which can integrate the hardware and software selected by the enterprise. The software can be used on any manufacturer's equipment to enable the entire management process from the beginning to the completion of Printing and Living in one go. Flexifold system The folding system is an important link in the post-press processing system, and is an indispensable step in processing printed sheets into a printer. In the past, most folding systems were equipped with different folding equipment according to the determined folding width and folding requirements. Generally, printing companies must be equipped with multiple folding equipment of different specifications to meet the various requirements of post-press processing. And these post-press processing is independent of the pre-press and printing processes, and also runs independently in terms of processing data. With the development of digital technology and workflow management in the printing industry, the folding system is required to be highly flexible and adjustable, which can achieve pre-press, printing, and post-press processing data sharing and instant data feedback, thus creating a flexible folding system ( Flexifold). The flexible folding system has many advanced features, such as equipped with built-in batch counter and total counter, the folding speed can be adjusted arbitrarily, equipped with various production information of current processing jobs, equipped with built-in fault diagnosis system, equipped with advanced micro-processing The device can provide single-page and multi-page detection, and has a memory system for paper jams in the paper feeder, folding plate and take-up table. It can realize a variety of non-standard folding. Since only the pre-press setting or just pressing the button can automatically adjust the folding, almost no preparation time before folding, so greatly improve the efficiency of the folding processing system. Super Efficient Processing Complex (SEO) In order to win greater living space and create greater profits in today's fiercely competitive printing industry, printing companies have been working hard to purchase advanced equipment, improve production processes, reduce processing costs and increase corporate profits, but often overlook other aspects, bottlenecks The effect causes costs and increases corporate profits, but often overlooks other aspects. The bottleneck effect causes the overall development of the enterprise to be slow. To this end, in recent years, industry experts have proposed a new concept of Super Effective Organization. In the face of the powerful impact of Internet technology, printing companies must fully understand the nature of the printing industry as a processing enterprise, and should focus more on how to reduce costs, increase printing added value, and integrate various forms of services. Then simply focus on how to improve the printing quality of printed matter. In fact, in recent years, the printing quality problems of most enterprises have been well valued and resolved. Now printing companies should consider themselves as the same processing union as other processing enterprises, and take ultra-efficient processing as their own development. The goal should not overemphasize the particularity of the printing industry. The change to the SEO concept will make the future changes in the entire printing industry focus on the improvement of the processing process, thereby truly changing our printing industry and achieving the goal of ultra-efficient processing. Combined ink technology (HIT) Hybrid ink technology (Hybrid lnk Technology) refers to mixing traditional printing ink with a sufficient amount of UV material to form a combined ink, and after the combined ink is printed, the printed ink layer is completely dried by UV drying first, and then UV glazing A new technology of processing to make the final printed product obtain a very uniform high-gloss surface. When applying UV coatings to traditional printing ink layers, due to the great difference in chemical composition and low compatibility between UV coatings and traditional inks, poor coating adhesion and gloss of printed products The degree drops. The combination ink technology was developed for this kind of defect. The advantage of the combination ink technology is that the combination ink uses a large tolerance, and in general it is similar to the printing suitability of traditional inks. Therefore, in terms of printing quality such as dot gain, color registration and printing contrast, it is almost the same as traditional ink, which is better than simply using UV ink. Compared with the traditional ink printing and glazing technology, the drying time is reduced, the printing speed is increased, and fully online UV coating can be achieved. Print Simulation Trainer (PSL) The Print Simulation Trainer (PSL) is a computer system that simulates the actual operation of a printing machine, just like a flight simulator that simulates the flight conditions of an aircraft. The printing simulation trainer can simulate the lithographic, flexographic or gravure printing process. The training teacher can use programming to arrange the desired printing failures, providing students with hands-on practical opportunities for each printing machine operation, thereby reducing the actual Downtime during operation on the printing press and waste of consumables. The printing simulation trainer is a dual simulation system that can perform printing control simulation on the one hand and print production simulation on the other hand. The printing simulation trainer can provide a full set of tools for printing quality control, including scanning register and scanning density meter with enlarged dots. It is very useful for printing operators to understand the printing process control parameters such as temperature, ink viscosity, PH value, and ink blistering required for drying, and can even reflect incorrect ink metering, unclean or damaged anilox rollers and doctor blades. The influence of web tension and printing speed on printing. The printing simulation trainer helps printing enterprises train skilled printing operators in a shorter time. At the same time, it can also be used in part to evaluate the operator's printing skills. At the same time, it can also be used in part to evaluate the operator's printing skills. The application of the printed simulation training device is shifting the training content from subjective description to hands-on operation practice, which has wide application value. Optical positioning high precision die cutting system The core of the optical positioning high-precision die-cutting system is a set of optical sensors and a dynamic die-cutting system called Way Block. Way Block uses a set of servo micro-drive devices. When there is still about 13 mm from the die cutting position, the optical sensor can read the pre-printed positioning marks on the die cutting piece and send a series of Way Block servo drive motors. The instruction indicates the amount of movement required for accurate positioning, and drives the moving paper to the preset position determined by the optical reading device. The X-direction (left or right) positioning of the die-cutting parts adopts a set of rolling rollers to grasp the end of the paper and move in micrometers. The Y-direction (advance or retreat) movement moves through the linear bearing. The amount of adjustment required for die-cutting parts is calculated through software, and the plane three-dimensional adjustment is performed on the adjustment platform to ensure that the die-cutting equipment can still work at a speed of 180 times / minute. This latest die-cutting equipment can die-cut printed matter in a different way from the past. The design is exquisite. It can die-cut paper, plastic or corrugated paper. Even if there is no alignment rule, it can die-cut very accurately and at high speed Print the desired print pattern. Networked printing production Networked printing production refers to the continuous production system from accepting orders to handing over. The core is to perform real-time calculation and control of every processing link (including processing equipment) of printing, to ensure the successful completion of printing. This system generates an electronic folder containing all important production parameters for each new printing job. On the printing production console, once the relevant data including the production plan deadline, requirements and enterprise production capacity are received, a dynamically changing workflow list can be automatically generated to guide the entire printing production process. After being carefully planned and delivered to the prepress department, the operator calls up the corresponding printing list, puts the relevant printing production data (such as images, logos, etc.) into the database, and can automatically generate the production folder to complete Subsequent work preparation for proofing data proofing, format proofing and CTP output. The production plan generated by the workstation also includes CIP3 data for folding, cutting and binding processing, and then transmitted to the corresponding processing equipment through the interface. Through networked printing production, the non-working time of printing production can be greatly shortened. But whether the entire printing production process is smooth, the key lies in whether the generated production operation data can be continuously transmitted and updated through the data control interface, so that the dynamic random calculation of printing activity can be realized. Sleeve material flattening system Generally, when using a simple flexibly deformable curve flattening roller, the paper belt is easy to produce tensile deformation while flattening in the horizontal direction through its defined curved arc surface, even if the tensile deformation is too large. The tearing phenomenon in the center of the tape, especially the ultra-wide and ultra-thin paper tape. The sleeve-type flattening system with controllable deformation will not be affected by the change of the tension of the tape itself during the process of flattening and depleting the tape, so it will not change the original tension distribution of the tape, thus maintaining The tension value that has been set while the tape is running is constant. In the printing process of paper tape, the paper tape enters from the compression area on the surface of the rubber sleeve, and then gradually enters the stretching area. Since the flattening process of the paper tape is attached to the surface of the sleeve and gradually completed by the deformation of the surface of the sleeve, it will not cause excessive deformation in the lateral direction of the paper tape. The flattening roller exerts an axial flattening force on the paper tape to eliminate wrinkles, but the magnitude of this flattening force comes from the surface deformation of the rubber sleeve, and the degree of deformation is through the two ends of the rubber sleeve. Controlled adjustment of the ring. By continuously adjusting the inclination of the collar, the degree of deformation of the deformable sleeve can be adjusted, thereby compensating for the deformation of the paper tape caused by changing the running conditions of the paper tape.
