UV Flexo Ink
Introduction
Although the viscosity of UV flexographic printing inks is lower than that of screen printing and offset printing inks, the addition of pigments will increase the viscosity, especially when the wetting, dispersion and stability of pigments are not handled well.
Features introduction
UV curing technology (including UV ink technology) is internationally known as "a new green industrial technology for the 21st century" for its excellent product performance, such as high efficiency, energy saving, no solvent emissions, and no environmental pollution. Conservation Service approved. The main characteristics of UV flexographic printing ink are as follows.
(1) Safe and reliable, no solvent emission, non-flammable, and no environmental pollution, it is suitable for packaging and printing products with high hygienic conditions such as food, beverages, tobacco and alcohol, and medicines. UV flexographic printing inks have been used in the field of foreign food packaging for many years without any problems.
(2) Good printability, high quality, no change in physical properties during the printing process, no solvent volatilization, stable viscosity, not easy to paste and stack, can be printed with higher viscosity, strong ink adhesion, high dot definition, tone reproduction Good performance, bright and bright ink color, firm adhesion, suitable for fine product printing.
(3) It can be cured instantly, with high production efficiency and wide application range. It has good adhesion on various printing carriers such as paper, aluminum foil and plastic. The product can be stacked immediately after printing without sticking.
(4) Excellent physical and chemical properties. The process of UV curing is a photochemical reaction process in which UV ink changes from a linear structure to a network structure, so it has many excellent physical and chemical properties such as water resistance, alcohol resistance, alcohol resistance, wear resistance, aging resistance, etc., which is beyond the reach of other inks. .
(5) The dosage is small. Since there is no solvent volatilization and high effective components, UV flexographic printing ink can be converted into an ink film nearly 100%, and the dosage is less than half of that of water-based ink or solvent-based ink, and the cleaning times of printing plates and anilox rollers can be greatly reduced.
Combining the above characteristics, UV flexographic printing ink has obvious advantages and development prospects from the perspective of environmental protection, quality, and technological development.
type
At present, in the domestic market, there are mainly the following types of UV flexographic printing inks to choose from.
(1) UV paper ink: fast curing speed, not easy to paste, high definition, bright color, bright and wear-resistant, good chemical stability, suitable for color fine product printing.
(2) UV polyolefin ink: suitable for printing on corona-treated PE, PVC, PET, BOPP plastic film and synthetic paper and other materials, with fast curing speed, firm adhesion, water resistance, wear resistance, and good printability.
(3) UV pearlescent ink: suitable for high-end packaging printing, with pearl luster and metallic luster, gorgeous texture, firm adhesion, and good printability. In addition to silver white, UV pearlescent inks also have a variety of colors and rainbow interference types.
(4) UV transparent ink: It is made of dyes or a mixture of dyes and pigments. It has strong transparency, bright colors and firm adhesion. It is suitable for printing materials such as vacuum aluminum plating, aluminum foil, silver cardboard, and laser paper. Get a hot stamp-like effect.
(5) UV varnish: mainly include paper UV varnish, polyolefin film UV varnish, matt UV varnish, hot stampable UV varnish and many other varieties, with fast curing speed, water resistance, resistance to Grinding, it can be varnished online or stand-alone.
