1. Product Profile
●    The latest model BK-898 silica inkjet adsorbent has been adopted advanced production technology to achieve stable quality. It features large pore volume and low iron contents, with super absorbent and color reducibility, which allows good ink absorption performance, fast speed drying , high color saturation, distinct gradations and good print quality.

2. Application principle
●    BK - 898 silica inkjet adsorbent is the adsorption material in color ink substrate surface coating, its coating carries on color ink. When printing, after ink is sprayed onto the paper through the ink head, the moisture is absorbed immediately and permeates into coating. At the same time, the silica adsorbent inside the coating can quickly absorb the moisture in order to ensure that no dye diffusion and color mixture happens so that the ink droplet and edge will be smooth and clear. Finally vivid image effect with high resolution and bright colors can be achieved.
