1. Not suitable for printing on rough materials. Oil based inks have poor adsorption and are prone to powdering during cutting, making it difficult to achieve clear printing results when the surface of the printing material is rough or porous.
2. Vibrant colors and high saturation. Due to the use of organic or inorganic pigments in oil-based inks, the color is bright, the saturation is high, and it is not easy to fade.
3. The drying speed is slow. The drying speed of oily ink is slower compared to other inks, and it is usually necessary to accelerate the drying process to shorten the time.
4. There are certain requirements for the material. Due to the fluidity of oily ink, there are certain requirements for the material's absorption and wetting properties, otherwise it is difficult to adhere and dry.
