In the printing industry, the fluidity of ink and the surface properties after coating are of great significance. Silicone oil, as an efficient additive, plays a dual crucial role of lubrication and anti-adhesion in it, significantly improving the printing quality and efficiency. 
Firstly, silicone oil, with its extremely low surface tension and excellent lubricity, acts as a "lubricant" within the ink. During high-speed printing processes, especially in rotary offset printing and intaglio printing, ink containing a small amount of silicone oil can effectively reduce its internal friction, thereby improving its fluidity and transferability. This enables the ink to be transferred more uniformly and smoothly from the printing plate or screen roller to the substrate, reducing ink smearing, wrinkling, and other phenomena during the printing process, and ensuring the uniformity of ink color and high clarity of the printed products. 
Secondly, the core function of silicone oil lies in its outstanding anti-adhesion (anti-re-sticking) effect. When printed materials, especially large solid areas or those using UV (ultraviolet) curing ink, are stacked or rolled up for storage, the un-dried ink layers are prone to stick to each other due to pressure and heat, resulting in damage to the graphics. After the ink dries, the silicone oil migrates to the surface of the ink film, forming a thin and smooth isolation layer. This layer significantly reduces the stickiness of the ink film surface, enabling the printed materials to effectively avoid sticking even when immediately stacked, ensuring the smooth progress of post-printing processing and the perfect appearance of the finished products. 
In conclusion, silicon oil, with its unique lubricating and anti-adhesive properties, not only optimizes the stability of the printing process but also ensures the quality of the final product. It is one of the indispensable functional additives in modern high-performance ink formulations.
