UV curable ink performance and application range

2018-08-28

UV ink is an energy-saving and environmentally friendly ink that can be hardened and adhered to UV light (ultraviolet) irradiation. It dries immediately after output, so the production lead time can be greatly shortened. It can be printed on various non-absorbent materials such as resin, glass, metal, etc. Rich ink series (soft, neutral, hard) can be used according to the purpose and material, from small accessories to large plates, architecture, and industrial design, all can make pattern printing and forming.

1. Low VOC (volatile organic compound) ozone-free ink

The pigment is directly attached to the material and cured after UV irradiation, so almost no VOC is generated. In addition, it does not use short-wavelength ultraviolet rays that generate ozone, so it is not only environmentally friendly, but also an environmentally friendly ink that takes the health burden of operators into consideration.

2. The curing method of UV ink

1. Use LED light source for UV irradiation to solve the problems of halogen lamps, such as: long idle time, high power consumption, large light source size, short service life, high heating temperature, etc.

2. Energy saving and long service life Compared with halogen lamps, the power consumption and heat generation of LEDs are greatly reduced when irradiated. Not only energy saving, but also the lifetime of the light bulb has been greatly improved, which is beneficial to reduce waste.

3. The calorific value is less, so the scope of use of materials is expanded. The heat generated by UV irradiation is less, such as acrylic board, PVC film, PET, etc., when the surface or shape is easily affected by heat and changes, it can also be used. There are high-color and detailed printed products.

3. Application scope of UV ink

The material has high applicability and a wide range of applications, such as: ink types suitable for gifts, promotional gifts, and boards, ink types suitable for printing on film or switches of touch panels, suitable for car body coatings and various packaging, etc. Ink type for surfacing or flex material.

requires attention:

1. White ink and transparent ink can be used together to have richer color performance. When using transparent materials, a layer of white ink can be printed on the bottom of the full-color pattern at the same time, which can have more vivid color performance.

2. If only colored ink is used, all colors will be transparent, and the original color cannot be reflected.

3. White × full-color ink, white ink can prevent light from passing through, and can present the vividness of the photo itself.

4. The relationship between UV ink and nozzle

1. Different nozzles correspond to different UV inks, and cannot be replaced at will, otherwise the nozzles will be blocked;

2. The quality of UV ink not only affects the quality of printing, but also affects the life of the nozzle;

3. Usually the shelf life of UV ink is 1 year, do not use expired ink, it is easy to block the nozzle.
