Three-dimensional printing
In the 1990s, video technology entered the era of three-dimensional photo, and human visual experience entered a three-dimensional field.
Stereoscopic printing is the development of stereo photography and is the crystallization of the exploration of stereoscopic display technology. It simulates the distance between two eyes of human beings. It shoots from different angles, records the left and right pixels on the photosensitive material, the left eye sees the right pixel, and the right eye sees the left pixel. According to this principle, the printing production process is called stereo printing.
The three-dimensional printing equipment and three-dimensional printing products have been fully introduced to the market, which is a major innovation in the printing field and an inevitable development trend in the printing field. The three-dimensional printing equipment has been able to produce a full range of products such as stereoscopic graphics, three-dimensional anti-counterfeiting labels, and three-dimensional rainbow materials. The three-dimensional anti-counterfeiting logo has excellent characteristics, and the three-dimensional rainbow material has a colorful and colorful world.
At present, three-dimensional printing is widely used in enterprise product packaging and decoration, trademark identification and anti-counterfeiting, product advertisement pictures, advertising posters, art decoration, museum exhibition window display panels, and human landscapes. Natural scenery pictures, stationery, 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, and the three-dimensional pictures 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 UV curing technology began in the 1960s and was used by German Wood Company for the curing of coating layers on wood surfaces. The world's first use of UV lithography was in the United States, and the British company was successfully used in 1970. Compared to traditional lithography, UV printing is a young and new technology, but it has become a very important printing technology.
In general, UV curing is a method of irradiating a photosensitive compound (ink) with a UV light source, so that the "photoinitiator" contained in the compound is stimulated by UV light, and is made in a very short time (less than 1 second). The "Polymer" contained therein produces a "radiation cure" of the glue cure. In the national display, it is also classified as "Electronic Beam Curing", which is called UV/EBCuring.
The lithographic UV printing is based on a lithographic architecture, using UV inks and UV light sources. Of course, some very important matching conditions are required to complete. In addition to printing, UV glazing for printing of transparent plastic film materials is one of the widely used glazing methods on the market.
JDF
JDF is an 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 targets all printing areas including e-commerce in the printing industry and information management systems in the printing industry. JDF has become one of the core elements of the CIP4 standard and is controlled by the CIP4 organization.
The two design goals of JDF include:
First, the exchange of information between different applications or systems for serving a complete print job;
Second, it faces the entire graphics field, including: consumables, design, and graphic creativity. Print on demand and e-commerce for each process.
JDF is an XML-based data exchange format that has the advantages of XML format - extensibility, so JDF is highly scalable and can adapt to new demands in the future. JDF can be flexibly adapted to each user's process.
Because JDF is a vendor-independent standard, it helps vendors develop their own applications. It provides users with a comprehensive, flexible solution that connects isolated systems in a print job into a complete user job service.
Biological ink
American scientists have long been working on a protein molecule called bacteriophagous: by illuminating its protein, it triggers a photochemical reaction cycle. The principle is that the photochemical reaction ring carries protons along the channel that surrounds the cell membrane. The purple color of this cell membrane is derived from the bacteriophage component called "retina". The amine acid in the cell membrane channel is firmly bound to the "retina". The "retina" in the dissolved state does not bind to the amine acid, and is pale yellow.
By alternately irradiating the two molecules of laser light of different wavelengths onto the protein molecule, the protein molecule can be converted between the purple structure and the yellow structure. It is this habit that stimulates the research and utilization of the rhodopsin. The film of the rhodopsin can also change its color according to the conversion of the external electric field. In conventional rhodopsin, low contrast color changes from purple to blue are formed under different electric fields. However, the rhodopsin structure produced by a certain mutant will change from blue to pale yellow under the action of a strong electric field. This protein film is sandwiched between transparent plates combined with a large number of electrodes to form a display plate. Applying the appropriate voltage to different parts of the film "writes" a page of the document or "places" an image on the display panel.
Like the ink on the paper, the image on the Violet display can also be seen under normal light, and the protein film also offers the advantage of high contrast.
Eicography
Eicography is a non-printing digital printing technology based on the principle of electrocoagulation. It is called "next generation" printing technology by many people in the industry. It is an inkjet method and electrophotography in the field of on-demand printing. The technical supplement of the way. Currently, prototypes using this technology are still under development.
The study of "Eicography" began with Canadian A. Castegnier, who was originally involved in the photographic development business. In 1971, A.Castegnier used the bubbles generated by the electro-decomposition reaction between the electrodes of yin and yang. It is believed that the gelatin layer can form a kind of gravure ink hole, which can be printed on plain paper by filling the ink in the ink hole (U.S. Patent 3,752,746) . But in fact, the occurrence of bubbles is very stable, and the experiment cannot proceed as expected.
However, A.Castegnier's research on this discovery did not stop there. In 1981, Eicorsy was founded and devoted to related research. It was not until 1984 that A. Castegnier produced the basic idea of Eicography, which used synthetic resin colloids to initiate electrochemical agglomeration between electrodes to form an image (U.S. Patent 4,555,320). Since then, Eicography has seen significant improvements in printing speed, quality and multicolorization.
At the NEXPO show in June 1996, Eicorsy collaborated with Japan's Toyo Ink Co., Ltd. to publish Eicography technology; at the IPEX show in 1998, the Model 200 Eicography press was on display, which is capable of 200 feet for full color variable data. At a speed of /min, 200dpi prints were produced; at the DRUPA show in 2000, they exhibited an Eico 400 Digital Press with a resolution of 400 dpi and a printing speed of 400 ft/min. Currently, the two companies are still improving the Elco400.
In the past printing process, the ink did not produce any chemical changes from the beginning to the end of the printing process; but in "Eicography", the ink uses the electrochemical resin solidification principle, based on the data signal and the current intensity between the yin and yang electrodes. , generate corresponding size dots to form an image. The principle of electrocoagulation is based on the chemical reaction between the functional group of the water-soluble resin and the trivalent iron ion on the surface of the metal anode.
The main features of "Eicography" that are still under further research and improvement are as follows:
First, the use of water-based inks, the environment is less polluted
Second, the printing speed is high and can reach 4 million feet per minute.
Third, it can achieve a resolution of 400dpi
Fourth, 256-step tones can be reproduced during the printing process.
EVA hot melt adhesive
EVA hot melt adhesive is a solid, fusible polymer that does not require solvent and does not contain moisture. The main component consists of basic resin, tackifier, plasticizer, filler, antioxidant and viscosity adjustment. The EVA hot melt adhesive is solid at normal temperature, and the colloid after heating and melting is a light brown translucent liquid.
EVA hot melt adhesive has the following characteristics: light brown:
First, the hot melt adhesive is a 100% solid at normal temperature. When heated to a certain temperature, it becomes a liquid, and once cooled 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 cure 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 rubber layer has both flexibility and hardness.
Third, there is re-adhesion. After it is cooled and solidified on the adherend, it can be reheated and melted and reused.
Fourth, it is easy to use. As long as the EVA hot melt adhesive is heated and melted into a liquid, it can be applied to the adherend, and after pressing and cooling for a few seconds, the need for complete curing can be achieved.
EVA series hot melt adhesive is green adhesive, non-toxic and solvent-free. Since its successful development in the country in the 1970s, it has formed a series of products for packaging, positioning, speaker-specific, bookbinding and refrigerator heat sealing. Products have been widely used in bookbinding, all kinds of packaging, home appliances without device assembly and positioning, cigarette packaging and filters, material composite, hot melt glazing.
Free Flow Digital Workflow Integration Software
The so-called digital workflow (Digital Workflow) refers to a set of processing procedures composed of digital hardware and software, so that the product-by-product processing process runs smoothly from beginning to end. 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 in the industry have proposed the concept of Free Flow digital workflow integration software. It refers to the integration of various software applications in a digital workflow into a software package with free-flowing open features. The integrated software comes with industry-standard workflow technology and an open interface that enables the hardware and software chosen by the enterprise to be integrated. The software is used on any manufacturer's equipment to make the entire management process from start to finish in one go.
Flexible folding system (Flexifold) system
The folding system is an important part of the finishing system and an indispensable step in processing the sheet into a printer. In the past, the folding system was 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 it is also independent in processing data. With the development of digital technology and workflow management in the printing industry, the folding system is required to have highly flexible adjustability, enabling pre-press, printing, post-press processing data sharing and real-time data feedback, thus creating a flexible folding system ( The new concept of Flexifold). The flexible folding system has many advanced features, such as equipped with built-in batch counter and total counter, arbitrarily adjustable folding speed, various production information for current machining jobs, built-in fault diagnosis system, and advanced microprocessor processing. The utility model can provide single-page and multi-page detection, and has a memory system for paper jamming of the paper feeding machine, the folding board and the receiving table, and can realize various non-standard folding, and the folding board can be steplessly adjusted and changed. Since the folding adjustment can be automatically performed only by the prepress setting or by simply pressing the button, the preparation time before folding is almost eliminated, so that the efficiency of the folding processing system is greatly improved.
Ultra-efficient processing complex (SEO)
In order to win more space and create greater profits in today's highly competitive printing industry, printing companies have been striving to acquire advanced equipment, improve production processes, reduce processing costs and increase corporate profits, but often overlook other aspects, bottlenecks. The effect causes cost and improves corporate profits, but often ignores other aspects. The bottleneck effect has caused the overall development of the company to be slow. To this end, in recent years, industry experts have proposed a new concept of the Super Effective Organization.
Faced with the powerful impact of Internet technology, printing companies must fully understand the essence of the printing industry as a processing enterprise, and should focus more on how to reduce costs, increase printing value-added and integrate various forms of services, without Then it is focused on how to improve the quality of printed matter. In fact, in recent years, the printing quality problems of most enterprises have been paid great attention to and solved. Now, printing companies should regard themselves as the same processing complex as other processing enterprises, with ultra-efficient processing as their own development. The goal, not to overemphasize the particularity of the printing industry. The shift to the SEO concept will focus the future changes in the printing industry on the improvement of the process, thus truly transforming our printing industry and achieving the goal of ultra-efficient machining.
Combined Ink Technology (HIT)
Hybrid lnk Technology refers to mixing a traditional printing ink with a sufficient amount of UV material to form a combined ink. After printing the combined ink, the printed ink layer is thoroughly dried by UV drying, followed by UV coating. A new type of technology that produces a very uniform, high-gloss surface for the final print.
When the UV varnish coating is applied to a conventional printing ink layer, the coating adhesion is not good and the gloss of the print is caused by the great difference in chemical composition between the UV coating and the conventional ink and the low compatibility between the two. Degree drops. The combined ink technology was developed for this defect.
The advantage of the combined ink technology is that the combined ink use latitude is large, and in general it is similar to the printing suitability of the conventional ink. Therefore, the printing quality such as dot gain, color registration and printing contrast is almost the same as that of the conventional ink, and it is better than simply using the UV ink. Compared with the traditional ink printing plus glazing technology, the drying time is reduced, the printing speed is increased, and the full on-line UV coating can be realized.
The combined ink technology can be applied to conventional printing presses. Conventional printing ink rolls and blankets can be used for printing. No special ink rolls and blankets required for UV ink printing are required, and special dampening solution is not required for printing.
Print Simulation Trainer (PSL)
The Print Simulator (PSL) is a computer system that simulates the actual operation of a press, just like a flight simulator that simulates the flight conditions of an aircraft.
The Print Simulator can simulate lithographic, flexographic or gravure printing processes, and trainers can use programming to schedule the desired printing failures, providing students with hands-on opportunities for each press's operations, reducing the actual Downtime during operation on the press and wasted supplies. The print simulation trainer is a dual simulation system that can perform print control simulation on the one hand and print production simulation on the other.
The Print Simulator provides a complete set of print quality control tools, including inspection registers and scanning densitometers with increased dot counts. It is useful for print operators to understand the printing process control parameters such as temperature required for drying, ink viscosity, pH, ink blistering, and even to reflect incorrect ink metering, dirty or broken anilox rolls and squeegees. The influence of web tension and printing speed on printing.
Print simulation trainers help printers train skilled print operators in less time. At the same time, it can also be used in part as an operator's print skill assessment. At the same time, it can also be used in part as an operator's print skill assessment. The application of the printed simulation trainer is shifting the training content from subjective description to hands-on operation, and has a wide range of promotional applications.
Optical positioning high precision die cutting system
At the heart of the optical positioning high-precision die-cutting system is an optical sensor and a dynamic die-cutting system called Way Block. Way Block uses a set of servo micro-motion drives. When the die-cut position is about 13 mm, the optical sensor can read the pre-printed positioning marks on the die-cut parts and send a series of signals to the Way Block servo drive motor. The command 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 die-cutting part is oriented in the X direction (left or right). One end of the paper is held by a set of rolling rollers to move in micrometers, and the Y direction (in or out) is moved by linear bearings. The Way Block can also rotate in a limited plane. The required adjustment amount of the die-cutting part is calculated by the 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 machine is capable of die-cutting prints in a different way than in the past. It is compact in design and can be die-cut for paper, plastic or corrugated paper. It can be cut very accurately and at high speed even without alignment rules. Get the desired print pattern.
Networked printing production
Networked printing production refers to the continuous production system from the acceptance of the order until the completion of the transaction. The core is to perform real-time calculation and control of each processing link (including processing equipment) of the printing, to ensure the successful completion of the printing.
This system generates an electronic folder containing all important production parameters for each new print. At the print 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, the printing is 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 and complete Subsequent print preparation, format proofing, and CTP output are all ready for work. The production plan produced by the workstation also includes the CIP3 data for folding, cutting and binding processing, which is then transferred to the corresponding processing equipment via the interface.
Through networked printing production, the non-working time of printing production can be greatly shortened. However, whether the entire printing production process is smooth or not, the key is whether the generated production operation data can be continuously transmitted back and updated through the data control interface, so that the dynamic random calculation of the printing activity can be realized.
Sleeve type belt flattening system
Generally, when a simple deflectable curved flattening roller is used, the paper strip is easily deformed in the lateral direction by the determined curved curved surface which has been formed, and even the paper is generated due to excessive tensile deformation. With a central tear, especially ultra-wide, ultra-thin paper tape. The sleeve-type belt flattening system with controllable deformation is not affected by the change of the tension of the paper strip itself during the process of flattening the pleating of the paper strip, and does not change the original tension distribution of the paper strip, thereby maintaining The tension value that has been set during tape operation is constant.
During the tape printing process, the tape enters from the compressed area of the rubber sleeve surface and then gradually enters the stretched area. Since the flattening process of the paper tape is attached to the surface of the sleeve, it is gradually completed by the deformation of the surface of the sleeve, so that excessive deformation of the paper strip in the lateral direction is not caused. The flattening roller eliminates wrinkles by applying an axial flattening force to the paper strip, but the flattening force is derived from the surface deformation of the rubber sleeve, and the degree of deformation is passed through the shaft of the rubber sleeve. The controllable adjustment of the ring is obtained. By continuously adjusting the inclination of the collar, the degree of deformation of the deformable sleeve can be adjusted to compensate for the deformation of the tape due to changing the running conditions of the tape.
