UV inkjet printing technology and applications

Inkjet printing principle and ink jet system

The so-called "inkjet printing" is a non-contact, stress-free, unprinted copy-printing technology. It has the common features of unprinted digital printing and can be printed with variable variables.

The principle of inkjet printing is to first input the computer-stored graphic information into the inkjet printer, and then through a special device under the control of the computer, the nozzle sprays droplets of ink droplets on the surface of the substrate, according to the effect of the charge. The surface of the substrate is directly imaged and becomes the final printed product.

Inkjet printing can be divided into two types, continuous and on-demand, depending on the inkjet system. The so-called continuous inkjet printing (Continuous Inkjet / CIJ), whether imprinting or non-imprinting, is the continuous generation of ink droplets in a flowing manner, and then transferred to form an image through the deflection of the electric field, and finally the non-imprinted droplets are recycled or dispersion. Drop on Demand/DOD (Don't Need Print) produces ink droplets only in the printed area, so the cost is relatively low.

Types of ink

With the continuous application of industrial ink-jet printing technology, the ink printing market is constantly introducing new products that can be applied to various ink-jet printers. These inks have their own characteristics. At present, there are mainly four kinds of inks that are widely used, namely water-based, oil-based, solvent-based, and UV-curable UV inks.

Water-based printing inks are generally used in short-term display products in printing rooms because they are not weatherproof.

Oil-based inks are pigment systems based on substantially dry, low-volatile oils. They are only suitable for a limited base material, namely paper and board, and are ideally suited for packaging printing applications.

In comparison, solvent inks are relatively inexpensive and can be directly printed on non-paint base materials such as light boxes, body wraps, non-wovens, and paper, and therefore have a wide range of applications in picture printing. However, solvent inks have a high content of volatile organic compounds that can adversely affect the human environment.

What is a UV ink? UV is ultraviolet light, which is the wavelength of light required to cure the UV ink. UV-cured ink consists of different chemical components, so the ink can be instantly cured under UV light. UV ink has a higher color density and a wider color gamut and is suitable for various needs. Typical UV inks generally include the following chemical components: monomers, oligomers, pigments, image transfer agents, and additives.

Agfa: Anapurna Ink

Anapurna Ink is specially designed for Agfa's various:Anapurna inkjet printers designed for piezo-type UV inks with fast, stable cure and ease of use. Excellent jet effect, excellent adhesion, suitable for a wide range of printing materials, is the best choice for indoor and outdoor applications. Use: Anapurna ink, the image is clear and bright, long-lasting colors.

Compared to other digital inkjet printing systems, the Anapurna UV printing system has many advantages. One of the most significant advantages is that it is ready to use. Compared to aqueous and solvent inks, Anapurna inks can be applied to a wider range of flexible or rigid substrates. The durability of the UV-curing ink also eliminates the process of laminating the printing surface in the production process, which greatly improves the production efficiency.

: Safety and Environmental Protection of Anapurna Ink

: Anapurna ink has no VOC (Volatile Organic Compound) contamination. Anaplastna ink uses a low-toxicity component and is not irritating. Just follow the instructions to ensure safety and reliability. Now more and more users are beginning to pay attention to environmental protection and are very concerned about the VOC content of the production floor. Therefore: Anapurna ink is very attractive.

Agfa uses state-of-the-art pigments: Anapurna inks to ensure long-lasting images. At present, ink printing is being tested on different substrates under different weather conditions. Initial results show that the images printed by Anapurna are sustainable for at least two years in outdoor sun and rain.

Applicable materials

: Anapurna ink printing materials are almost unlimited, whether flexible media or rigid media are equally applicable, such as paper, vinyl, canvas, wood, glass, ceramics and so on. : Anapurna was used in Italy to repair the external walls of the Vatican church. The image was printed directly on the stone. The effect was excellent.

UV printing ink is rapidly developing into the mainstream of a new generation of platform digital printing presses: Anapurna ink and advanced: Anapurna wide industrial ink jet printer is a perfect match, allowing you to perform inkjet printing more reliably and efficiently. To take the lead and gain more profits.
