Aqueous coating

Aqueous coating is a liquid finish, primarily composed of water and resins, applied to the surface of printed materials before drying. It serves as a protective barrier against scuffs, moisture, and fingerprints while enhancing the visual appearance of the ink layer. Unlike solvent-based alternatives, aqueous systems use water as the primary carrier, offering a lower volatile organic compound (VOC) profile and reduced odor during production.

In business card production, this coating is often used to achieve a uniform gloss or matte texture. It can be applied as a top coat over CMYK inks to increase color density and provide a smooth tactile feel. While it does not offer the same high-gloss contrast as spot UV or the texture of lamination, aqueous coating provides a cost-effective, all-over finish that stabilizes the surface for further processing or shipping.
