6 differences between offset and flexo ink

Flexographic (flexo) and offset inks are different in several ways:

1. Composition: Flexo inks are typically composed of water-based, solvent-based, or UV-curable systems, while offset inks are usually oil-based.

2. Viscosity: Flexo inks are more fluid than offset inks, which are thicker and have a higher viscosity.

3. Drying time: Flexo inks dry more quickly than offset inks, which can take longer to dry and can require the use of special drying equipment.

4. Substrates: Flexo inks are designed for use on a wide range of substrates, including flexible packaging materials, labels, and corrugated board. Offset inks are typically used on paper-based substrates such as coated paper, newsprint, and uncoated paper.

5. Color saturation: Flexo inks have higher color saturation and can produce brighter colors than offset inks, which can be useful for creating eye-catching designs on packaging materials.

6. Printing process: Flexo printing uses a flexible printing plate that is wrapped around a printing cylinder, while offset printing uses a flat printing plate that transfers ink to a rubber blanket before being applied to the substrate.

Overall, the choice between flexo and offset inks will depend on the specific printing application and substrate being used.
