Improve ink absorption ability:
The color inkjet paper coating needs to quickly absorb water from the ink, and silica sol can effectively accomplish this task due to its porous nanostructure. This feature not only speeds up the drying of the ink, but also prevents the ink from spreading on the surface of the paper, thus ensuring printing clarity.
Enhanced color performance:
The core of print quality lies in color reproduction and saturation. Due to its high transparency, silica sol can reduce the scattering of light in the coating and improve the purity and brightness of the color. Experiments show that the color reproduction of color inkjet paper using silica sol coating is about 20% better than that of traditional materials.
Improve print clarity:
The smoothness of the paper surface microstructure directly affects the printing resolution. The silica sol particles in the coating can fill the tiny pores on the surface of the paper, making the ink distribution more even and thus achieving higher printing clarity.
Enhance the durability of the coating:
Silica sol has excellent mechanical properties and can significantly improve the wear resistance and water resistance of color inkjet paper coating. Paper coated with silica sol can maintain excellent print quality even in humid environments.
