Ink is an important material used for packaging materials printing, it will be printed through the pattern, text performance on the substrate ink, including the main components and auxiliary components, they are evenly mixed and repeatedly rolled into a viscous gelatinous fluid. Ink is used in the printing process to form the graphic information material, so the role of ink in printing is not trivial, it directly determines the printed image of the tone, color, clarity and so on. In printing we need to understand the composition of ink and ink classification.
Laser cleaning is a new type of environmentally friendly cleaning methods, it can not only remove metal surface oxides, but also able to remove non-metallic workpieces, such as ceramics, plastics, etc., but also able to remove dust on the surface of the workpiece, oil, floating rust, coatings, etc., and will not hurt the workpiece itself.
It is not easy to modify the ink after it dries. Since the ink is printed on corrugated paper, if you use chemical reagents to wipe it off, the surface of the corrugated paper will be wet and wrinkled. If you use adhesive tape to remove the corrugated paper for reprinting, the layer of paper on the surface of the corrugated paper will also be glued off, damaging the corrugated paper. If there are a large number of printing errors that can't be corrected, you can only throw them away, which is undoubtedly a waste of money. Laser cleaning, on the other hand, can quickly clean the printing ink from the corrugated paper without harming the surface of the corrugated paper, making the corrugated paper ready for secondary use.
