1. Drupa 2012 Dr. Lanta's Thousands of Snow
At the Drupa 2012 exhibition, Landa Lanta from Israel exhibited roll-feeding paper and Zhangye digital nanoprinters in Hall 9, a total of six models. Since Landa first cooperated with Komori Press, it signed a technical license on April 27, 2012, and signed a cooperation agreement with Manroland on April 30, and launched it on May 2 with Heidelberg Press in Drupa 2012. Before signing the contract, except for KBA, the four major printing press manufacturing companies in the world are all small and medium-sized factories with relatively small production capacity. Among them, Ryobi cooperates with Gongyao to complete electronic imaging printing equipment. Because of the endorsement of the three major companies, many people went to the ninth hall to see the newly released Nanotechnology Nanographic printer of Landa Company after the news was leaked at the Drupa 2012 venue. If you want to say that the human-machine interface of these machines uses a huge touch screen, not only can you control the entire production on the screen, but also you can use a smart phone to do remote printer operation. It is very modern. If Dr. Benny Landa was developed in his own talent, then his performance tension is even more convincing. With the gorgeous lights and the hot field of singing and dancing performances, many audiences have simply integrated into this gorgeous In the performance show, an extremely successful Nanographic printing show known to the printing industry all over the world was formed. After returning to calm, it is faced with an important key issue in printing technology. Does it work? Can it create a market or create a different production path?
Dr. Lanta's advantage, he said that Nanographic technology is very environmentally friendly, as long as the water can be printed, this may be possible. The second point is the speed of a flat printing machine (A1 paper has 8000 to 12,000 sheets), the third point is that the cost will be lower than that of a lithographic printing machine, mainly because the ink layer is thin, all attached to the fiber surface, and there is no penetration so efficiency High, so as long as a small amount of ink is sufficient to print ink color performance. The fourth point, Landa masters inkjet and transfer technology, and shares it with many printing presses. These conditions are very attractive and good intentions, so many people are also very convinced and optimistic about Lanta's nanotechnology.
2. Dr. Lanta is connected with printing by Indigo
It is believed that a small number of readers know that Dr. Benny Landa announced the digital printing technology of electronic imaging liquid electronic ink at the 1993 IPEX Birmingham Printing Machinery Exhibition, and there were more than 200 in Indigo Copier technology at that time. Patent, but Indigo ’s technology is not in the printing machine or the transfer technology using the blanket, but the magnetic field induction imaging of electronic ink, and the ink must be 100% transferred from the imaging OPC (organic photoconductor) cylinder to the blanket, Then 100% of the blanket is transferred to paper or printing media at one time, so electronic ink is Indigo's most successful and key technology. Because many OPC imaging toners are transferred directly to the paper surface, but the electronic ink is designed for liquid heating and transfer, so heating it to 160 ° C on the blanket can keep the ink non-skinny and solidifying activity, transfer to the printing material It can be cured immediately because of no shaking and no heat. The printing ink received on the blanket due to the high temperature, but the moisture and a small amount of solvent quickly evaporate, so the printing ink is transferred to the paper surface and the media surface, it will not penetrate and there is capillary blooming, keep it very Good printing dots and line printing quality, no IR or UV to do forced curing. Under the application of these new technologies and inks, Indigo's initial quality has performed well, but there are still many operational difficulties that have not been resolved. One of them is printed on coated paper because it does not penetrate and is only posted on The surface of the ink can be wiped off with an eraser, so there was a joke at the time. It was Clinton ’s scandal in Ruwinsky ’s trainee. It is best to print the testimony with Indigo, because there is room for change. What we are more worried about today is that Landa Nanographic Printing Technology cannot print the same quality print samples as Indigo at the time, which is worrying and doubtful. Indigo's equipment was sold to HP in 2002, and the hardware and software could meet market demands. Does Landa still have such a model?
3. Will nano pigment technology be good and cheap?
It is understandable that Landa Nanographic technology has not reached the level of current lithographic printing in terms of speed and quality, because Nanographic uses the Kyocera Kyosera inkjet head at 600dpi to produce at a speed of 150 meters per minute (B19,000 sheets), then Only the 1200dpi output of the flat printing machine, the quality of the printer or a little lower is understandable, because such as Fuji Film JetPress 7200, JetPressF are variable dot 1200dpi, which can have CTP2400dpi output, which is comparable to understandable , But the speed of B2 is about 2800 ~ 3200 sheets per hour, and the printing circumference is 520mm. If this question of speed has been put in the evaluation position, the printing speed of 1200dpi can reach 150 meters per minute, perhaps 1.5 to 3 years. So Dr. Landa said: The quality will meet the ideal after 18 months; Komori President Komori said that the ideal quality can be achieved after 3 years.
However, the author suspects that it is very difficult to reach the end of the line with more than 100 lines in the 600dpi nozzle. It is difficult to reach the finished product of more than 100 lines. However, Landa's sample is an AM dot, not an FM dot. Therefore, it is not the biggest problem that the resolution is slightly worse on the sample, but the white streaks of the nozzle are blocked. In addition to the UV-cured ink, the ink head is not blocked when the ink head is not irradiated with UV light. Under the disturbance of temperature and wind, the ink is very easy to cure and hinder the smooth spraying of the nozzle. This is also a major reason why Fuji Film, Komori, Konica Minolta use UV spraying, and Landa Nanographic does not use UV curing technology. Will one day be improved to UV curing?
Dr. Benny Landa said: We use a 500-nanometer ink layer, which uses nano-pigments of 10 nano-meter diameter, so it will cost less than ordinary lithographic printing ink, which is a very attractive advantage. However, as long as the thickness of the printing ink is compared, the pigment for lithographic printing is about 1μ in particle size, and the printing ink layer is 2 to 3μm. If the layer is maintained at 40-50 nm, it is one-fiftieth of the lithographic ink layer, and the cost may be equal to that of lithographic printing. Today, Landa Nanographic must use an inkjet thickness of 500 nanometers, which is about one-fifth of the thickness of lithographic ink. It is easy to understand that there is no opportunity for lithographic printing at a considerable price, but there is no opportunity for cheaper.
4. Conclusion
Rather than pouring cold water on Landa ’s Nanographic technology, I have seen years of exhibition experience telling me to watch real guns, that is, loading paper rolls on the printer, and then introducing how the machine is easy to operate and how to produce quickly. Take out the beautifully printed products one by one from the printed end. This does not require gimmicks to cover up. This is hard work, not tricks. I have seen how many printing presses, and to print good things in the exhibition hall, it takes at least four or five days to install and adjust, and there are as many as six Nanographic machines, only one or two, and there is no printed product. The audience takes home. Some equipment was published four years ago, but the quality is still not satisfactory after four years. Landa introduced the technology to several famous lithographic printing presses, especially Komori Press has been developing two-track Landa machines for two years. The contract for technology transfer was only signed in 2012, and the Imprimia IS29 slips developed by Komori and Konica Minolta Both the sheet paper B2UV inkjet and the Imprimia IW20 roll-to-roll inkjet have good product displays, which shows that they do not want to waste R & D time and other inkjet technologies.
At least Dr. Benny Landa, Lanta, is very good at using the technology he transferred. This time the Nanographic long-length transfer tape has a buffer and evaporates water before printing on the media, so that the nano ink layer does not have too much fluidity. It has a shallow effect on the surface of the printed medium, otherwise the surface of the medium directly sprayed with the nozzle becomes a 100% general inkjet printer, and its nanotechnology is like most inkjets, everyone is a nano pigment. And Dr. Landa has not yet solved the technology of nozzle clogging on the ink head, which still has a long gap to enter practical production. After all, at the IPEX venue in 1993, I heard and saw Dr. Lanta's new equipment Yingzi, and after nearly 20 years later, he saw his gray hair and beard gestures on electronic media, and still actively advocating his new When technology leads the way in the future, I suddenly think that a prophet is sometimes very lonely, because Xeikon, which previously released high-speed printing of electronic imaging toner on the same stage, has changed the toner imaging to the same electronic ink imaging as Indigo in Drupa 2012. The Xeikon 8800 was published, and Dr. Lanta, who is also a prophet, is leading for nearly 20 years.
