Shenzhen Jinjia Ink specializes in the production of glass UV ink, they only produce UV ink, and it is more professional to do glass UV ink!

Shenzhen Jinjia Ink Company has production!

UR84 series UV glass ink generally does not need to add thinner, nor does it need to add any waterproof additives, and there is no limit to the use of pot life. If the viscosity is high due to low temperature, UVT-002 diluent within 10% can be added to adjust.

The curing of UV inks depends on the level of UV energy, black and blue inks dry more slowly and require higher UV energy, yellow and red, transparent varnish is easy to cure and requires less energy. In order to ensure the full curing of dark ink and the excessive curing of light ink, the principle of printing light ink first and printing light ink after printing should be followed.

UV energy according to different colors, UV varnish only needs 600MJ energy, black ink needs about 1000MJ energy to cure. 80w cm medium pressure mercury lamp 10-15cm lamp distance 6-10 seconds cure.

Generally, the coding on the glass is a UV glass inkjet printer, which uses UV anti-scratch ink, and has good adhesion for logo cleaning.

The glass UV printer is to transfer the pattern that needs to be printed to the computer, and after a series of processing, it is printed on the printed object through the UV printer, and the printed material is required to be flat, such as glass, tile, wood board, leather and acrylic. The UV ink used dries immediately to meet the requirements of fast shipment.

Glass UV printer refers to:

1. Printing glass flat material.

2. It can also be called glass printer, UV printer, universal printer, etc.

Glass UV printer is a digital inkjet printer that prints patterns on glass products.

The models include Heshun 1610UV printer, Heshun 2513UV printer, Heshun 2030UV printer and so on.

UV metallic inks are light-curing inks that can be printed directly onto metal surfaces, including surface-treated metal substrates and surface-finished metals, and not metallic or metallic effect inks in the ink.

When purchasing UV ink, it is necessary to "check the face and look at the color". UV ink is sensitive to ultraviolet light, and if the UV ink continues to be exposed to ultraviolet light (such as sunlight and fluorescent lamps) after construction, the UV ink will continue to react and turn yellow, which is the defect of UV ink itself. For conventional UV inks, it cannot be fundamentally improved for the time being, but the degree of yellowing of UV inks of different manufacturers is not the same, unless specific non-yellowing or extra-white UV inks are used.

For the discoloration of the UV ink after varnishing, the main reason is the problem of the ink. There are some pigments in the ink, such as light blue, which is a blue acid lake pigment, which is an insoluble pigment pigment formed by organic dye triphenylmethane dyed on the physique pigment such as aluminum hydroxide, ** low, the hue is distinct, but its light resistance, solvent resistance and alkali resistance are poor, and the red phase is easy to be dissolved, weakened or disappeared when encountering alcohols and other solvents or alkalis. These pigments are feasible if used in book inks (the surface is no longer varnished after printing), but if they are used in color box inks, they are very dangerous, because most color boxes are post-processed.

The detection method is to drop a drop of bottom oil and ink on the surface of the ink, and see if the ink changes color after 1 hour, which is very obvious.

For printed paper, if the ink is discolored, you can use forced ink drying, such as drying or leaving it for a little more time to solve, or use a neutral base coat, solvent-free UV ink, solvent-free book UV oil.

ink and other methods to reduce the tendency of the ink to change color. When we want to buy in the ink, we also have to "taste" to evaluate the smell of UV ink has two indicators, one is the smell in the construction process, which is mainly the residual solvent in UV ink, under normal circumstances, the amount of residual solvent is less than 2%, under special circumstances, such as cigarette pack UV ink requirements are less than, but in today's soaring oil, many businesses have added a large number of solvents, such as alcohol and toluene, etc., in order to reduce the cost of UV ink, the highest can reach 25%, This is not conducive to the long-term development of UV ink and environmental protection.

Another indicator to evaluate the smell of UV ink is the residual smell of UV ink after construction, which can not disappear after a long time of general time, the main thing is that the UV ink is not properly selected, and some chemicals with a large but cheap smell are used, which is difficult to fundamentally improve, mainly the cost and the problem of choosing the right material.

More importantly, the purchase of UV ink is the first to be evaluated, and the purchase of UV ink should be evaluated from the brand and cost performance of the ink. Many ink multi-grade merchants are uneven, and you may buy high-quality products without comparison, or the ink products are not authentic. We also have to consider the problem of transportation cost while purchasing UV ink, so it is very important to choose a reasonable and trustworthy ink supplier.

UV ink: there is a rigid UV ink, there is a neutral UV ink, there is a flexible UV ink.

UV (ultraviolet curing) ink refers to the use of ultraviolet light of different wavelengths and energies to polymerize the monomers in the ink binding material into polymers under ultraviolet irradiation, so that the ink is film-forming and drying. UV inks are also inks, and as inks, they must have bright colors (except in special cases), good printability, and suitable curing and drying rates. At the same time, it has good adhesion, and has the characteristics of wear resistance, corrosion resistance, weather resistance and so on.
