UV ink uses UV irradiation to dry the ink and form a film. After light irradiation, the photosensitive material (monomer) in the ink receives the energy of ultraviolet light, excites and cross-links with the pigment.
UV ink is mostly used for the packaging of high-end products and the overall or partial gloss of fine prints. It can display visual effects such as raised, wrinkled, foamed, frosted, precious stones, refraction, and varnish, giving people a gorgeous, dignified and elegant appearance. Sensory impression.
UV inks dry quickly, and they typically dry in more than 10 seconds under standard UV energy. UV inks have excellent abrasion resistance, which can reach 15 million times, 5-6 times higher than that of general inks.
In use should pay attention to: the need to use a special ink roller and blanket; printing shop to maintain 22 ± 3 degrees Celsius; printing should always fully mix UV ink, always pay attention to water, ink balance; can not be mixed with other inks; ultraviolet irradiation to standard , to install reflectors; below 25 degrees Celsius dark storage, can not be stored for a long time; damage to the printing workers, the workshop pay attention to exhaust, the operator wear overalls, gloves, sunglasses; restrictions on the use of UV in the inner packaging of food ink.
The substrates using UV inks are creased when they are folded and are currently expensive.
2, temperature change color ink
Appearance discoloration morphology: colored at low temperatures, colorless at high temperatures. Available colors are red, rose, pink, vermilion, orange, yellow, yellow green, grass green, sky blue, turkish blue, blue, dark blue, black and so on.
Temperature interval setting: from -15 degrees Celsius to 75 degrees Celsius. Different temperature ranges can be set depending on the needs of various products. The general color change temperature setting range is from 2 degrees Celsius to 10 degrees Celsius, and the color density gradually decreases from low temperature to high temperature until it is nearly transparent.
3, photosensitive color ink
Appearance color change form: Photochromic ink printed products under the sun (ultraviolet) irradiation, due to ink absorb sunlight (ultraviolet) energy and produce color changes; lose sunlight (ultraviolet) irradiation, and return to the original color.
Basic four colors: colorless - red colorless - purple colorless - blue colorless - yellow
4, luminous ink
Luminous luminous pigments must absorb a variety of visible light in order to store light energy before they can automatically emit light in the dark and can be used indefinitely.
In use should pay attention to:
Need to use neutral or slightly alkaline transparent resin, mixed use;
To disperse the raw materials at high speed, it is best to use glass or ceramic containers for storage;
The length of storage depends on the amount of moisture content, should pay attention to moisture. Humidity is too high, easy to black or form a lump;
In order to reduce the precipitation of luminous powder, it is necessary to use high-viscosity resin, or add anti-settling agent, and stir evenly before use. Diluents can be used to adjust the viscosity, do not use heavy metal compounds as additives;
In order to improve the brightness and light-emitting time of the printed image, the printed background should be dominated by white or reflective colors;
Screen printing, in order to obtain better luminous effect, the mesh is best for 80-120 mesh;
The thickness of paint and ink is preferably not less than 100um, such as 130-150um, the best effect (this thickness can be achieved by 80 mesh screen printing twice);
The recommended amount of luminous powder is 10% to 60% of the total weight. The more the amount is, the better the luminous effect is. According to different printing materials, different types of transparent inks are selected. For example, the metal material for printing should be selected for the special metal ink, and the PVC material for printing should be PVC. Special ink, and the higher the transparency, the better the effect;
If you need to use water-based paints and inks, luminous powders must be wrapped with special microcapsules to provide durability.
5, LCD ink
The liquid crystal ink utilizes a temperature difference and the color exhibits a seven-color conversion.
6, scent ink
Scented inks use microencapsulation technology to wrap the fragrance and release it slowly in an open space. There are a variety of scent, such as rose, jasmine, strawberry, lemon, sandalwood, lavender, mint, camphor, etc., which can be selected according to your needs.
