Fluorescent ink As a Unique Ink , Primarily used in anti-counterfeiting and packaging Print Regions (such as employed in bank notes, bank checks, stamps, card, and sophisticated smoke, oil, pharmaceuticals, cosmetics and other name brand safety products and packaging and printing, and so forth.), by gravure printing, offset printing, flexo printing technique, and so on.. But in current years in research and improvement with the fluorescent ink is a lot more comprehensive, thorough and complete, and constantly created for precision screen printing of fluorescent ink, fluorescent ink so that the screen printing application is a lot more comprehensive, such as the show window for printing , decal, bumper protection gear, industrial insurance, equipment, body and Outside marketing , Posters, magazine covers, invitations, and other cloth regular. Specifically in the outdoor and indoor Advertisement The silk screen printing, because printing with normal ink, fluorescent ink printing can not match the benefits of their network in India and those advertisements increasingly well-known application. As the fluorescent ink is a unique ink, the use of technology and there are some differences among the basic ink, as a result, must be familiar with its attributes and different printability can print out the fine print goods.
Fluorescent ink is frequently referred to as hidden-colour ink is to UV (200 ~ 400nm), and so forth. issued below the visible light irradiation (400 ~ 800nm) of the unique ink. The principal components of fluorescent ink fluorescent Yen (dye) material, which is the functional light-emitting paints, pigments and the common distinction is that when the external light (which includes UV) irradiation, with certain forms of power, not transformed into heat energy, but photons to visible light energy absorbed kind of release, resulting in various hues of the fluorescence phenomenon. Uncommon shade combine to type diverse bright colors, and when the light green fluorescent protein to cease light, the light phenomena will disappear. This is at times invisible ink or infrared light in the UV luminescence, because of its convertible and hidden characteristics, and colour copier can not be replicated on the precise characteristics of their application is becoming increasingly popular. Fluorescent ink is the use of fluorescent pigments by adding a particular percentage of resin binders, fillers, stabilizers, and drying, grinding or 3 roll ink Grinding machine Processed. Fluorescent pigment is the main raw material manufacturing fluorescent ink, UV light exposure can be excited and show colour. According to their molecular structure can be divided into inorganic and organic fluorescent pigments fluorescent pigments, inorganic fluorescent pigment fluorescent pigment, also identified as ultraviolet light, which is produced of metal (zinc, chromium, and so forth.) or rare earth oxide and sulfide trace with the active agent by calcine, colored or light-colored, rendered in different colors beneath ultraviolet light. Its stability is great, but challenging to disperse in the oil medium, water resistance is poor, the plate has some put on and corrosion. Organic fluorescent pigment, also identified as daylight fluorescent pigments, mainly synthetic resin containing fluorescent dye solid answer, is a fluorescent dye (fluorescent) to be dispersed in a transparent, brittle resin vector produced of, the date of irradiation, the emission is distinct from the ordinary colour higher-brightness visible light, accompanied by the acceptable amount of blended or non-fluorescent pigments, accessible in different colors of fluorescent paint. Traits of organic fluorescent pigment is easily synthesized, dispersed in the oily medium is excellent, but most of sunlight excitation, the existing majority of undesirable stability. In addition, uncommon earth fluorescence complex, it has ready a simple, simple to refine, the dispersion in the oily medium, soluble, colorless in visible light, ultraviolet excitation green fluorescent protein fluorescence showed strong outcomes, and stability of the several positive aspects, but costly, and because of rare earth fluorescence complex organic fluorescent ink viscosity is tiny, simply caused in the printing resulting emulsion floating dirty or ink roller inking, specially in a colorless, transparent ink, need to have typical checks to stop leakage arising as deinking printed phenomenon, for that reason, this kind of fluorescent ink is generally not suitable for lithography.
Ink or paint through the reflected light to display color, but the typical ink colors and the reflection characteristics of fluorescent inks of distinct colors. Fluorescent ink can convert short wavelength light superposed on development and fluorescence wavelengths of light, via the conversion and stacking to kind a unique brightness and visibility fluorescent colors. If the red fluorescent red with some reflection, and the other colors (green, blue and purple) into the red as the red comes out of the wavelength, as is the internal radiation from objects out of colors, the use of fluorescent ink printing obtainable 4 instances ordinary ink brightness and visibility. Fluorescent ink in the dim light, such as dusk and dawn, it is really bright.
Fluorescent ink manufacturing method calls for the production and printing of a particular remedy approach. We know that fluorescent particles will make a variety of light and special clean colors such as yellow, orange, red, crystal red, green and blue and so on. In a dark environment, the fluorescent ink will send the light. The crucial is to have the effect of this special colour ink includes pigments that can absorb ultraviolet energy and convert that power into longer wavelengths of visible light.
