Technological change leads the development of printing technology, high-tech printing process and ink technology inventory

With the improvement of people's requirements for commodity packaging and appearance, many companies have higher and higher requirements for appearance and packaging printing technology. To enhance the beauty and grade of printed matter through fine processing is an important means to realize the value-added of printed matter. Advanced printing technology can make the packaging of goods more lifelike, more attractive to consumers, but also improve production efficiency. Almost every technological innovation in the past can bring the printing industry to a new level, so with the passage of time, what new markets or hot technologies are worth paying attention to in today's printing industry? Let's take stock of them one by one.

nano-printing

In the printing industry, the ability to express details is one of the important criteria for judging the quality of printed products, which provides the potential application of nanotechnology. At Drupa 2012, Landa has shown us the most eye-catching new digital printing technology of the time. According to Landa, the nano printing machine integrates the characteristics of digital printing flexibility and traditional offset printing efficiency and economy, which can not only achieve high production efficiency, but also seamlessly connect with the existing working environment of printing companies. With the development of science, from the fields of biomedicine to information technology, the size of the components used is shrinking and the complexity is increasing, and these requirements encourage scientists to strive towards the direction of nanoprinting technology with high resolution and high throughput. A few days ago, scientists at the Technical University of Denmark announced an important new nano technology, which can produce a resolution of up to 127,000, marking a new breakthrough in laser printing resolution, which can not only save the data that can not be seen by the naked eye, but also can be used to prevent fraud and product fraud.

UV-LED curing technology

The speed and quality of printing ink curing significantly determine the final printing effect. The growing share of the current UV ink in the global printing market has also LED to the development of its supporting products, such as UV-LED light source curing equipment for curing UV ink. Uv-led curing is considered to be an environmentally friendly green technology, also known as 3e technology, that is, energy saving (energy), environmental protection (environment), economy (economy), it combines the respective advantages of printing technology and UV curing technology, both printing technology in the use and operation of convenience, and UV curing technology in the economy Technical and technical advantages. Weitai Group, a well-known domestic printing press R & D and manufacturer, has designed and developed a variety of targeted UV-LED light curing material formulations by adjusting the interaction of photoinitiator, chemical formula and light source. The new UV-LED light source curing system developed by the company not only inherits the characteristics of the traditional water-cooled UV system with a wide spectrum, a wide range of ink adaptation, fast speed and low energy consumption, but also makes special use of patented methods to increase the sealing of the light-emitting chip, which can enhance the characteristics of water vapor resistance and instantaneous high current resistance, and makes a major breakthrough in increasing the service life of the chip. The wide application of UV-LED printing technology marks the printing industry into a new era of efficiency and environmental protection.

Biodegradable ink

With the rising voice of green environmental protection, sustainable development has attracted much attention in the packaging industry, and its importance has become increasingly prominent. The printing and ink market, which is closely related to the packaging industry, is also paying more attention to environmental protection and sustainable development. Therefore, a new generation of environmentally friendly inks and printing processes continue to emerge. ClimaPrint, an organic biodegradable ink made by Indian ink manufacturer EnNatura, is one of the most representative products. Biodegradable plastics can be degraded through the action of microorganisms and integrated into the natural material circulation system. Gravure inks used in printing are widely used, which are basically composed of three components: colorant, coloring material and additive. Biodegradable resin is added to the above components to become biodegradable gravure inks. Printed matter with bionon-degradable gravure ink, even if placed in an environment conducive to biodegradation, will not appear shape change, weight reduction and so on. It can be predicted that in the near future, it will enter an era of using continuous recycling materials in ink.

Waterless offset printing

Waterless offset printing is an offset printing process that does not use water or a wetting system. The printing and packaging industry has always been cautious about waterless printing. However, in the past two years, the waterless offset printing process has made great progress through the collaboration between press manufacturers, paper and ink manufacturers. Waterless offset printing uses silicone rubber coated plates, special inks, and temperature-controlled presses to print more substrates, including paper and a variety of non-absorbent substrates, more simply and efficiently. Due to the participation of water in ordinary offset printing, the printing process will bring a lot of printing faults due to water, such as deinking roller, no ink, slow drying, incomplete printing dot, insufficient ink color is not bright, small luster, conjunctival strength, etc., and waterless offset printing because there is no water, the printing will not curl, and the printing waste and waste in operation are also significantly reduced. And the printing products printed with waterless offset printing ink have the advantages of bright color, large gloss, fast drying, complete dot and so on. At present, waterless offset printing has been more mature in thin film printing.
