What Ink Types Are Suitable for Computerized Flexo Printing Slotting Machines?

1. What Are the Common Ink Types Used in Flexo Printing Slotting Machines?

The most commonly used inks in flexo printing slotting machines include water-based inks, solvent-based inks, UV-curable inks, and LED-UV inks. Each type offers unique benefits depending on the substrate, printing speed, and drying requirements.

2. Why Are Water-Based Inks Popular for Flexo Printing Slotting?

Water-based inks are favored for their eco-friendliness, fast drying times, and compatibility with various substrates like paper and corrugated board. They generally produce vibrant prints and are suitable for food packaging when compliance is met.

3. How Do UV and LED-UV Inks Improve Flexo Printing Efficiency?

UV and LED-UV inks cure instantly when exposed to UV light, significantly speeding up production and reducing ink absorption into substrates. These inks provide high-quality, durable images and are ideal for non-porous materials.

4. Are Solvent-Based Inks Still Relevant for Computerized Flexo Slotting Machines?

Yes. Solvent-based inks offer excellent adhesion, vibrant colors, and resistance to environmental factors. While less eco-friendly, they are still preferred for specialized packaging requiring chemical resistance and flexibility.

5. How Should Ink Selection Be Matched with Specific Slotting Machine Requirements?

Ink must be chosen based on the machine's drying system, substrate type, and desired print quality. Slotting machines with computerized flexo units typically require inks that dry quickly and maintain sharp edges during die-cutting slots, making UV and water-based inks preferred options.
