Gravure Inks
Gravure inks are specially formulated for gravure printing, a high-speed printing process commonly used for large-volume production such as magazines, packaging, wallpapers, and decorative laminates. These inks are typically low-viscosity so they can easily fill the engraved cells on gravure cylinders and transfer smoothly onto substrates. Gravure inks offer excellent color consistency, fine detail reproduction, and strong adhesion on materials like plastic films, foil, and paper. They also dry quickly, making them suitable for fast production lines.
Solvent-Based Inks
Solvent-based inks use organic solvents to dissolve pigments or resins, allowing the ink to adhere well to non-porous surfaces. They are widely used in packaging, labels, flexible films, and outdoor printing due to their strong durability and resistance to moisture, chemicals, and abrasion. These inks dry quickly as the solvent evaporates, ensuring efficient printing operations. However, solvent inks require proper ventilation and environmental controls due to solvent emissions.
Water-Based Inks
Water-based inks use water as the primary carrier instead of chemical solvents, making them more environmentally friendly and safer for workers. They are commonly used in paper packaging, corrugated boxes, and food packaging applications. Water-based inks produce less odor and reduce harmful emissions while still delivering good color performance and print quality. Advances in technology have improved their adhesion and drying speed, making them increasingly popular for sustainable printing solutions.
Flexo Inks
Flexographic (flexo) inks are designed for flexographic printing, which uses flexible relief plates to print on various materials such as plastic, paper, metallic films, and labels. Flexo inks can be water-based, solvent-based, or UV-curable, depending on the application. They are valued for their fast drying speed, versatility, and ability to print on both absorbent and non-absorbent surfaces. Flexo printing is widely used in packaging industries due to its efficiency and ability to handle large print volumes.
