UV ink market forecast The use of UV curing inks and coatings began in the 1970s, currently in the printing industry occupies a large market share, including in lithography, flexographic printing, letterpress printing and other fields of application. It is predicted that by 2005, the market for UV-curable inks will rise from $ 1.1 billion in 2001 to $ 1.5 billion. In the United States, the use of UV inks and coatings for the printing industry output value of about 1.5 to 200 million US dollars per year, the amount of ink and paint roughly the same. Of course, the growth rate depends on the development of the branch market, the annual growth rate range of 4% to 20%, the majority of the company's growth rate of up to 7% to 12%, in some areas, such as inkjet printing, Printing and flexo and other fields, due to the current market share is low, so the growth rate is relatively large, can reach 20%.
For the time being, roll packaging accounts for the largest market share, it can be applied UV curing ink to direct mail, business forms, folding cartons and credit card production. Narrow Flexo has been widely used in UV inks and coatings. In the packaging and printing, whether it is offset or flexo field, the application of UV ink and coatings is a growing trend. Energy curing products are entering every corner of the market, with great economic significance. Electron beam EB curing accounts for about 30 million to 50 million US dollars, accounting for almost 13% of the total energy curing market.
Compared with the UV curing and drying system, EB equipment is relatively expensive and covers an area of ​​relatively large, so the growth rate is relatively slow, although the price of equipment has been a certain decline, but the use of chemical raw materials are still more expensive. Functional ink refers to the ink to add some ingredients, so that the ink with optical properties, electronic properties, physical properties, biochemical properties and substrate surface decoration performance.
These functional inks were the most developed in the 1980s. However, to the 90's, the market downturn, many products disappeared. One of the most important reason is that with the color, color function of the pigment cost is too high. In the 80's, ink manufacturers developed a lot of functional ink. Recently, in addition to the surface processing decorative functional ink, the mirror metal, UV light color ink and other high-priced functional ink are put into practical application. Molding, transfer and other surface processing and decoration mostly use functional ink. In accordance with the use of surface decoration, functional ink can be divided into the following categories.
Functional ink with physical effect 1. Optical ink A. UV light color ink with optical function of the functional ink, the most representative is the ultraviolet light color ink.
The ink in the sun or general lighting, only white. If the ultraviolet light, it will send a bright fluorescent color. The ink is added to the inorganic fluorescent material, can show green, yellow, orange, red, pink, blue, white and other different fluorescent colors. It uses inorganic fluorescence The latest screen printing ink Optical effects Ultraviolet light luminescence, UV light shielding, liquid crystal display Electronically insulated, conductive, EL, electromagnetic heat, temperature foaming, temperature display, infrared radiation, molding, inlay molding stress Frosting, logo, scraping ink, adhesive, transfer ink, spices ink drug corrosion, screen printing stripping biochemical effects of antibacterial, anti-halo absorption, adsorption, reaction water absorption, inkjet printing, oxidative corrosion pigments, fillers Of the processing of decorative imitation corrosion, mirror coating, prism film three-dimensional, glossy thick ink layer, embossed printing, Braille printed fine lines forming crystal lines, high and low lines, crack lines functional ink physical chemical surface decoration, functional Classification materials and equipment for ink Screen printing materials as color-developing materials, according to use, the fluorescent material dispersed into the appropriate adhesive, and make it ink.
Compared with ordinary fluorescent ink, this ink has heat resistance, solvent resistance, light resistance, chemical resistance and so on. When printing, it is best to use 100 to 200 mesh screen. The standard color is green, yellow, orange, red, pink, purple, blue, white, other mixed colors from a variety of ink from the deployment. The light source for ink coloring is an ultraviolet light source. UV light color ink for display parts, fabric, logo, security, automotive dashboard and so on.
Storage light (luminous ink) The use of light storage pigment luminous ink, the absorption of sunlight and light energy stored in the ink, and then release the ink in the accumulation of light energy, send light to light in the dark light. The previous light-emitting ink luminescence time up to 20 ~ 30min. Recently, the newly developed light-emitting ink luminescence brightness and luminescence time is 8 to 10 times the previous storage ink, the color of green, red, blue light color. In order to improve the brightness of the residual bright light, the ratio of the addition amount of the storage pigment to the addition of the resin is 1: 1. The thickness of the ink layer can be thickened, and the screen printing using 100 to 180 mesh is most suitable.
(EL light-emitting ink) EL (electroluminescence), an inorganic phosphor / induced electron layer sandwiched between the electrodes, and an AC voltage is applied to change the electric field of the phosphor to emit fluorescence. The base material of the light-emitting surface is a transparent conductive film-vapor-deposited polyester film. The fluorescent ink is printed on the surface of the vapor deposition and emits light through the fluorescent ink. EL phosphors are affected by humidity and the brightness will become weak, so to prevent moisture from penetrating into the inside. Generally use microencapsulated fluorescent substances, binder resin, with a wet barrier layer of the role of good water resistance. Insulating ink, is the natural resin powder dispersed in the ink, a good insulation effect, can print 2 layers, 3 layers of ink.
Reverse electrode using conductive ink, the general use of carbon paste, but the use of silver when the light emitting area. In the vapor deposition layer surface printing linear circuit generally use silver paste. Protection layer to have a good insulation, water resistance. Printing UV-curable insulating inks can form a tough film. Can be laminated protective film. Power is generally 80 ~ 120VAC / 400Hz. High voltage, high frequency can improve the brightness. But will reduce the life of EL lamps. In addition, high temperature, too wet will reduce the life of EL lamps. EL lamp, it is best to use liquid crystal display of UV lamp. Other forms of light can also be used as needed.
2. Electronic role A. Silver ink In the circuit printing, the general use of silver paste ink. Printing of the substance In most cases, the use of polyester. The fine silver powder is dispersed into the binder of the polyester resin and becomes the silver paste ink. As the physical properties of ink, firmness, tortuous, electronic impedance values, these physical properties are very important. Electronic resistance is generally 10 Note that the ink surface of the film dry bad, the electronic impedance will increase dramatically.
It is preferable to use a far-infrared dryer to dry at 120 to 130 ° C. In the high humidity environment, will cause the silver paste ink circuit in the movement of silver particles, short circuit phenomenon. In order to prevent the movement of silver particles, an insulating ink is printed on the silver paste circuit as a protective layer, or a paste is mixed with silver paste.
B. Carbon paste (electrode paste) The filler used in the carbon paste is black carbon, acetylene black carbon, graphite and so on, according to the type, particle diameter, impedance value changes. Most of the carbon paste used in the membrane switch is printed on the polyester material. The carbon paste is an evaporative drying ink.
C. Insulating Ink To prevent the movement of silver paste particles, to prevent short circuit between circuits, and to prevent contamination, use insulating ink. Insulating inks are solvent-based inks and UV-curable inks. The former is based on vinyl resin, polyester resin as the material of the ink; the latter is a good ink film thickness, improve the insulation resistance, to prevent the ink particles moving UV ink.
3. Stress The stress effect of the ink with sandblasting treatment with the cover ink. In addition to sandblasting part of the ink to cover the process, sandblasting treatment, with warm water stripping cover part. The part that is not covered forms the desired pattern. Blasting ink used for blasting is thick and elastic, easy to peel, is a flexible UV elastic ink. This kind of ink is often used in the decoration of glass tableware and stainless steel cutlery.
Antirust masking ink is characterized by UV curing resin internal stress is very high and joined the stripping agent, so the adhesion is very low, very easy to peel. When stripping the printed film, it can not stop or break in the middle of peeling, otherwise it will form a very tough layer. This ink is suitable for the coating part of the cover, the protection of the surface of the material, the temporary protection of the printing surface, can also replace the use of protective film.
Second, the functional ink with the function of the chemical ink used as information recording media used in the CD plate surface printing or writing worksheet 1 inorganic fluorescent material characteristics of the general particle diameter red, green and blue light wavelength ink. Is a high viscosity ink, with good transparency and softness. The use of such ink printing screen size can not exceed 150 mesh. The use of thick wire mesh or coated photoresist can increase the thickness of the printing ink layer.
3. Braille Braille UV Ink Braille Braille UV ink is ink for printing Braille books. Braille printing using metal mask plate or thick film sensitive glue straight between the plate. Braille dot must have a height of 0.3 to 0.5mm, abrasion resistance, good surface strength, good touch and transparency. When printing, braille can not have bubbles, dotted dot diameter can not be expanded and have a certain height of the ink layer. Requirements printing ink must have a high viscosity and the appropriate thixotropy, good defoaming.
4. Partial glazing in the graphics part of the substrate, in order to impose glazing, the use of printing UV varnish way, this way is called the graphics partial glazing.
Mainly in the advertising, brochures are used. Recently, the printing company introduced the manual used in this type of printing for the most, due to glazing, extinction contrast contrast, to give people a special emphasis on the feeling. Will print the text of the text part of the light, give people a photo with the same sense of reality. In the offset printing, in order to highlight some of the text effects, but also the use of UV polishing process.
5. Natural formation of fine lines is not just printed graphics, UV ink curing drying process, UV ink itself also formed irregular fine lines.
A. coral-like lines to form coral-like lines of ink, ink printing in the same time the ink blistering, the bubbles gathered together, irregular continuous accumulation of parts and no bubbles smooth part of the formation of coral-like lines, it can be said to be instant The formation of three-dimensional sense of the beautiful coral texture materials and equipment screen printing with the directory and other text. UV ink (RCD ink) developed in accordance with this purpose and made it printable. RCD media used in the UV ink is hydrophilic polymer monomer by adding a binder, and then into the hydrophilic particulate powder, dye adsorbent made of ink. Application of screen printing method, the ink printed on the CD-R surface, and then UV light curing process. After you can print ink, can also be used water pen, oil pen to write. Write penetration phenomenon rarely, dry quickly.
Third, the surface processing decorative ink with a functional ink UV ink has a good surface hardness, ink layer thickness is very good, but also has the characteristics of gloss, abrasion resistance. Evaporation of dry ink does not produce this surface finishing effect. In order to obtain this kind of surface finishing effect, UV ink is used in most cases. The ink can achieve matte effect, imitation metal corrosion effect, molded strip effect, extinction effect, according to the different filler in the ink and produce different effects. The filler has various types such as urethane foam, silica and so on.
1. Prism ink Prism ink is the polyester holographic film made of very small particles as a color of the material into the ink made of printing after the prism effect, can be similar to the effect of diamond brightness. In the prismatic ink, need to mix 5% to 15% of the holographic film fine particles. Printing prism inks on black substrates; or printing prism inks above the transparent film, and printing black on the back of the transparent film gives a good coloring effect.
2. Thick ink layer UV ink thick ink layer UV ink is transparent road. This ink is UV ink. Due to the different mesh size, coral-like pattern ripple size is also different. Low mesh screen pattern ripple on the large; high mesh screen pattern ripple on the small. Screen printing, in 30s through the ultraviolet light irradiation. In the gold cardboard, silver card paper on the use of this ink effect is very good.
B. Crystalline lines The lines of the ink are heating the reactive ink. In this ink, a blocker is added, and the surface curing rate is different from the internal curing speed to form a crystal grain. Mainly used for glass, metal surface crystal lines processing decoration process. The ink is a UV-curable ink.
C. wrinkle lines in the substrate on the printing of corrugated lines of UV ink, first through the low light ultraviolet radiation, resulting in surface curing and ink within the semi-cured state. As the surface of the UV ink curing shrinkage, resulting in concave and concave pattern of the lines. Then, through the ultraviolet light exposure, so that UV ink (external and internal) curing, you can achieve contraction of the wrinkles.
The future of functional ink screen printing has two major advantages: First, you can print in a variety of shapes of substrates; the second is to print a thick ink layer. These advantages make the functional ink display its application characteristics in the applicable screen printing range.
To effectively use these advantages, the production of high-precision products, to adapt to new requirements, to achieve more special processing technology. You can also use a variety of functional ink combination, showing a new graphics. In short, must continue to follow the requirements of the market to develop a new functional ink.
