The Difference Between UV Ink And Ordinary Ink In Box Packaging
Under the trend of pursuing environmental protection, the packaging box printing industry has also begun to use more environmentally friendly inks. Although the cost has increased, in response to the call for low-carbon environmental protection, UV inks are still accepted and widely used by everyone, so it is compared with ordinary inks.
In comparison, what are the main advantages of UV inks?
Fast Drying And Excellent Performance
Under UV light irradiation, UV ink can be completely dried and cured in only 1/10 second to a few seconds, and the speed is breakneck. It can be dried during the transfer of online printing to ensure that post-processing can be performed immediately after printing, which is conducive to the post-processing procedures and saves the cycle of finished products.
Besides, since the UV ink only dries under the irradiation of ultraviolet light, the ink’s performance can remain stable during the printing process or even in the ink fountain for a long time, and there will be no skinning on the ink roller.
Save Energy And Comply With Environmental Protection
Compared with any ink except natural evaporation drying ink, it saves energy and is less wasteful. Compared with traditional inks, the polymerization and drying of UV inks are more thorough. After curing, the solid content of the ink is close to 100%, without any evaporation or solvent contaminants.
The ink film is 100% cured and almost free of VOCs, that is, during the curing process. In other words, it will not emit or emit minimal volatile organic compounds and will not cause environmental pollution. It makes the air in the printing environment fresher, has a low odor, is beneficial to environmental protection and employees’ health, has no pollution to the environment, and complies with environmental protection. The requirement of green printing is environmentally friendly ink. The ink has a high flash point, is not easy to burn, saves heat energy, and is safe to use.
The Equipment Occupies A Small Area
Compared with thermal drying, the drying device occupies less area. Printing can be streamlined, saving the workforce and economical. What preparations should be made for ordinary printing machines to use UV ink? In the case of the same dry film thickness, the printing area is large. Besides, the printed matter has good color stability and high brightness.
The Ink Particles Are Small And Can Print Delicate Patterns
UV inks can provide bright and bright colors to ensure good gloss and bright colors; due to the firm, fast-drying, and cross-linking of the printed ink layer, such an ink layer has high abrasion chemical resistance. Therefore, UV inks can be used for printing on outer packaging that requires wear resistance.
The Printing Adaptability Is Strong, And The Printing Range Is Wide
UV ink can meet the needs of various substrates. The range is vast, such as paper printing, plastic printing, tape measure printing, printed circuit boards, chrome plate printing, electronic parts printing, metal surface printing, aluminum foil surface printing, etc. In terms of printing methods, UV ink can be applied to various printing methods such as letterpress, gravure, screen, and offset.
