Latest Technology Development
In today's highly respected short-run printing and on-demand printing, inkjet printing, as a printing technology that can realize variable data printing, is getting more and more attention, and inkjet printing technology continues to mature. More and more manufacturers have released their innovative inkjet printing technology, and even have tried to put it into application.
1. New technology of inkjet printing on demand
On-demand inkjet printing technology is slower than continuous inkjet printing technology, but it has the advantages of better quality and wider application fields. At the same time, the technology is perfect and mature, and the printing speed is steadily increasing. The recognition of printing technology continues to improve.
FUJIFILMDimatix exhibited new technologies including ShapedPiezoSiliconMEMS technology, a piezoelectric drop-on-demand inkjet printhead and a single paper path inkjet printing equipment prototype. Among them, ShapedPiezoSiliconMEMS technology has intellectual property rights, which is a kind of high-precision printing on the surface of various substrates such as flexible substrates, plastics, glass, metals, silicon, and thin films. It provides unlimited opportunities for the expansion of inkjet printing technology to "beyond printing", which is applied to high-speed, low-cost manufacturing technologies such as RFID, flat panel displays, and circuit boards. It is undoubtedly a hot spot for drupa2008.
It is also worth noting that Kodak introduced the Versamark VL2000, its first high-speed on-demand inkjet printer in history. The new Versamark VL2000 maintains the same speed as the existing Versamark VT3000, while the color image quality has been greatly improved.
2. New technology of continuous inkjet printing
Continuous inkjet printing technology is widely used as a high-speed digital printing equipment. It is widely used in digital printing equipment. There will be many new exhibits on drupa2008. Hewlett-Packard has launched its Latex printing technology and the first printer to use the technology in response to rising international environmental protection equipment. The core of the technology is the use of its new environmentally friendly Water-based Latex ink, which has excellent water solubility, odorless, safe, non-toxic and harmless; and high image quality, which can be maintained for 3 years without fading without film coating, suitable for outdoor use Print business.
Kodak will also exhibit its newly developed Stream inkjet printing technology and its concept machine at drupa2008. Stream is a continuous inkjet printing technology that uses a new concept of "thermalpinch-off". At the same time, 10 to 60nm particles are added to the ink. The ink has unique drying performance, faster speed and more excellent Although the print quality cannot be immediately applied to industrial applications, it represents the future trend of Kodak inkjet printing technology.
3. Inkski and Stream inkjet printing technology debut
In the latest product release article above, we have a detailed understanding of Kodak Stream inkjet technology. As a new inkjet technology, Kodak's Stream is considered by most customers to be the most promising, because it is suitable for both short- and long-form printing, and Inkski is a technology that will soon be put into commercial application .
Both Stream and Inksk use inkjet methods that are different from mainstream technologies on the market, but they have in common that they want to achieve higher linear speeds with a single printhead. It is understood that most current inkjet devices use multiple print heads for production. On Drupa, Kodak exhibited a device with a speed of 2.5 meters per second (500 feet per minute). After using Stream technology, its speed is expected to become faster. Inkski claims that its print head can work at a speed of 10-20 meters per second, claiming that their company has proven this concept and will launch its own concept print head and printing machine in the next year and four to five years .
Other suppliers in the industry are also full of expectations for this technology, and hope to see printing machines with Inkski printheads on the market soon.
Inca's Baxter believes that it is not time to eliminate piezoelectric drop-on-demand inkjet technology. Piezo technology may be impacted by new technologies, but it will never be replaced.
Because the speed of the new print head can reach ten times that of existing products, Baxter summarizes the development of inkjet technology in the past few years.
He said: "Since we launched Eagle44, the world's first and fastest flatbed printer in April 2001, we have successfully increased its output to the original model (Onset). 25 times. To some extent, the development speed of inkjet technology has exceeded the famous Moore's rate. Moore's law was proposed by Gordon Moore, one of the founders of Intel, whose content is : The number of transistors that can be accommodated on the integrated circuit will double every 18 months, and the performance will also double. If measured from the perspective of cost performance, then the current inkjet technology has been 10 times higher than before Times. "
With the improvement of the entire printing system and the improvement of supporting tools, the speed of the print head will be further improved. In addition to speed, today's inkjet technology is working hard to find breakthroughs in other production factors-powerful functions, barrier-free operation and printing flexibility on a variety of substrates.
4. CrystalPoint technology
CrystalPoint technology is a "new printing technology" developed by Océ, which combines the advantages of toner and inkjet technology, can produce monochrome and color waterproof documents, suitable for large-format printing.
The CrystalPoint process uses microsphere toner, which is called TonerPearls by Océ, and this toner can be converted into a gel. The toner glue is then accurately printed on the paper surface by inkjet, including recycled paper and non-coated paper. The printing effect is half-light, and the image will not change when it meets water.
Océ also stated that CrystalPoint technology is a product with a "completely sustainable concept" because TonerPearls colloidal toner used in this technology is printed by inkjet and does not produce ozone or odor. In addition, the semi-gloss finishing used by this equipment can also compensate for the small needs of paper glazing.
Among them, the Océ ColorWave600 large-format digital printing machine launched by Océ on Drupa is the first device to adopt this new technology. The machine focuses on two customer groups: one is CAD in the fields of construction, engineering and civil engineering Design and printing, the first is the printing of retail posters and store promotions.
The latest field of application
The traditional view is that inkjet printing is not very suitable. Even now many printing companies believe that inkjet printing only occupies the market in two application areas: large format printing and low resolution address printing. However, there are two other newly developed application areas that have received considerable attention from printers-hybrid printing and bill printing.
1. Mixed printing brings flexibility to newspapers
The first application is the combination of inkjet and offset printing, which can be called hybrid printing. For this purpose, the inkjet print head can be installed on an offset or flexo printing machine. Therefore, printing plants can print variable content on traditional analog printers. Inkjet technology brings the required speed and resolution, so that when a traditional printing machine prints variable content, it is not necessary to reduce the speed of the machine.
This method is most suitable for direct mail, forms and lottery printing. At this drupa exhibition, the combination of inkjet and offset printing technology was demonstrated. The content of inkjet printing changed 100%, and its quality was no different from that of offset printing. To this end, the application of mixed printing enters a whole new space.
It is reported that Kodak recently cooperated with Manroland to integrate Kodak's inkjet head on the offset newspaper rotary. This innovation has brought new possibilities to the newspaper media, and has made many contemporary people feel that old and inflexible newspapers have gained new vitality. The flexibility of adding variable data to newspapers provides opportunities for newspapers and media owners.
Printing plants can protect existing equipment investment through hybrid printing, which can extend their press life and application range.
2. Transaction bill printing can display brand characteristics
The second important trend is of great interest to computing centers and transaction bill printing service providers: inkjet technology replaces the method of reprinting on previously pre-printed color prints, thus providing an economic possibility, that is, all The content can be printed on unprinted paper in real time in one process. Therefore, pre-printed paper inventory is eliminated. In addition, there is no longer the risk of scrapping preprints due to outdated content. According to foreign investigations, 30% of the paper pre-printed with offset printing and stored in the warehouse must be disposed of for this reason.
The Transpromo market provides a good example of inkjet printing systems. Targeted advertising information is integrated in the transaction bill file, so companies can improve their customers ’communications.
Transpromo was a widely discussed topic at the Drupa exhibition, and the field showed a trend of expanding color printing growth. Brand-name product managers are keen on color, and inkjet printing can replicate unique spot colors.
