The Development History of Temperature Varying Ink
Thermal ink, a magical material that can change color with temperature, has a development history full of innovation and breakthroughs. From its initial laboratory discovery to its widespread application today, thermochromic ink has gone through a long and exciting journey. The story of thermal ink began in the mid-20th century. Some chemists accidentally discovered in the laboratory that certain compounds change color when heated. This phenomenon has aroused strong interest among scientists,...
Introduction to Color Changing Materials
Color changing materials and special materials are special chemical raw materials that play a role in anti-counterfeiting or special functions. They are widely used in industries such as tobacco and alcohol, pharmaceuticals, cosmetics, daily chemical products, textiles, and adhesive trademarks. They are also used for anti-counterfeiting packaging of famous brand products such as certificates, receipts, passports, mobile phones, computers, children's toys, and baby products. These materials...
CCL、 Fulingt and Tecnau build new factories, and two important industry mergers and acquisitions
Fulingt will build a factory in Salvi, India Flint Group announced that it will build a brand new manufacturing plant in Salvi, Baroda, Gujarat, India. This new factory covering an area of 9000 square meters will mainly produce water-based inks and coatings to meet the demand of the local paper and cardboard packaging market, while also producing energy curing inks to serve the label and narrow web rotary printing industries. This expansion is an important step for Flint Group to continue to...
The globally leading materials technology company "Innovative Ink" has announced the successful development of a revolutionary color changing ink, which is expected to bring about significant changes in various fields such as anti-counterfeiting, packaging design, and fashion industry. This color changing ink called "ChromaShift" can present completely different colors under different light, temperature, or angles, adding a unique visual dynamic effect to the product. The core technology of...
A new type of material called "thermal ink" has sparked a craze in the packaging and printing industry. This ink can change color according to temperature changes, as if possessing "magic", adding fun and interactivity to product packaging, while also bringing new solutions to anti-counterfeiting and security fields. The secret of temperature sensitive ink lies in the thermal sensitive material it contains. These materials are highly sensitive to temperature changes, and when the temperature...
Fluorescent ink is one of the more widely used inks in ticket printing, and its main component is fluorescent pigment. Fluorescent pigments are functional luminescent pigments. The difference from ordinary pigments is that when external light (including ultraviolet light) is irradiated, it can absorb a certain form of energy, and excite photons to release the absorbed energy in low visible form, thus producing different Fluorescence of the hue. The combination of different color lights forms an...
China has been producing ink for a long time. The predecessor of ink was pine ink. China uses pine smoke, glue (mainly cowhide glue, which plays a role in bonding cigarette ash), and water to make black ink. Started as a writing tool and later used in the woodblock printing industry. Ink developed rapidly in the early stages of China, but after the Middle Ages, it remained stagnant and satisfied with traditional secret formulas, lacking creativity. At that time, wooden printing in Europe was...
UV fluorescent ink classification
UV fluorescent inks can be printed by various methods such as screen printing, gravure printing, embossing, offset printing, and flexographic printing. With the development of screen printing technology and equipment, screen printing has become an ideal printing method for fluorescent ink in recent years. The screen printed fluorescent ink prints can form uniform ink film layers, which is necessary for good gloss, stability and weatherability. Since the particle size of the photoluminescent...
Introduction to anti-forgery ink
Anti-forgery ink can be divided into embossed, gravure, screen printing, offset printing, and water-based flexographic ink according to printing forms. Anti-forgery ink can be divided into paper ink, printing iron ink, news paper ink, plastic ink, etc. according to different substrates. Magnetic anti-forgery ink uses magnetic substances as pigments, such as iron oxide and cobalt doped iron oxide. The characteristics of these anti-forgery inks are achieved by implementing different external...
Smell feast, opening up a new sensory experience for printed materials
The secret of fragrant ink lies in the microcapsule technology contained within it. These microcapsules are made from natural or synthetic fragrances, with a diameter of only a few micrometers, and can encapsulate fragrance molecules inside. During the printing process, microcapsules are evenly distributed in the ink and firmly attached to the surface of the paper. When readers touch or rub printed materials, microcapsules rupture, releasing fragrance and creating a unique sensory experience....
Fluorescent screen printing ink
In the history and growth of the screen printing industry, many technological innovations have emerged that have made a significant contribution to the industry. These include the use of knife stencils, the use of ready-to-use screen inks, the standardization of photographic printing plates, the creation of screen printing international associations, the generation of mechanical printing, the spread of information technology required by screen printers, and fluorescence Ink development and so...
The main components of ink and the functions of each additive
Printing ink is a paste-like colloid composed of color materials, binders, fillers and other ingredients evenly mixed. As a viscous fluid, ink has different properties due to different varieties, such as thick and thin, viscosity, fast drying and slow drying, etc. Therefore, a correct understanding and understanding of the role of ink components in ink is of great significance for accurately adjusting ink characteristics, meeting the creativity of various printing conditions, and improving...
Guide you to learn about Anti-forgery ink！
Anti-forgery ink printing ink is an important part of Anti-forgery ink technology. Anti counterfeiting ink refers to ink with Anti-forgery ink function, which is composed of colorants, binders, and ink additives. It is a special printing ink made by adding special Anti-forgery ink materials to the ink binders and processing them through special processes. The reason why it can prevent counterfeiting is that it uses pigments and binders with special functions in ink to prevent...
How to choose the type of dispersant？
1. Selection of dispersant An excellent dispersant should meet the following requirements: good dispersion performance, prevent aggregation of filler particles, proper compatibility with resin and filler, good thermal stability, fluidity during molding and processing Good; Does not cause color drift; Does not affect the performance of the product; Non-toxic, inexpensive. The amount of dispersant is generally 5% of the mass of the masterbatch. 2. Types of dispersants (1) Fatty acids, aliphatic...
The world's first "phase change ink" can achieve passive temperature control
Science and Technology Daily, Beijing, March 28th (Reporter Zhang Jiaxin) - Researchers at the University of Melbourne in Australia have developed the world's first "phase change ink" that can change the heating and cooling methods of houses and cars. It can achieve complex "passive climate" control and has great potential to help reduce energy consumption and global greenhouse gas emissions. The research was published in the latest issue of the Royal Society of Chemistry's Journal of Materials...
