Solvent-based inks are printing inks that use a solvent as the primary carrier for the color pigments. These inks are known for their durability and resistance to water and fading, making them suitable for outdoor applications. They are commonly used in large-format printing, signage, and packaging. The solvent in these inks evaporates during the drying process, leaving behind the pigment on the surface. While solvent-based inks offer vibrant colors and excellent adhesion, they can emit volatile organic compounds (VOCs), which may pose environmental and health concerns. Proper ventilation and safety measures are essential when using these inks.
