Flexographic Printing Ink Formula
Flexographic printing inks are available in various colors and formulations, including process colors (CMYK) and Pantone spot colors. The choice of ink depends on the printing requirements, substrate characteristics, and specific printing conditions. flexographic printing ink formulation has specific characteristics that make them suitable for this printing process:
- Quick Drying: Like web offset printing inks, flexographic inks are designed to dry quickly to accommodate the high-speed printing process.
- Low Viscosity: Flexo inks have a lower viscosity, which helps in transferring the ink to the printing plate and then onto the substrate smoothly. The low viscosity also allows for efficient ink flow in the press.
- Water-Based or Solvent-Based Formulations: Flexographic inks are available in both water-based and solvent-based formulations. Water-based inks are more environmentally friendly and are commonly used for food packaging. Solvent-based inks offer excellent print quality and adhesion to various substrates but may have more significant environmental and health considerations.
- Good Adhesion: Flexographic inks are formulated to adhere well to a variety of substrates, including plastic films, paper, and metal foils. Proper adhesion ensures that the printed images are durable and do not peel off easily.
- Resistance to Abrasion and Chemicals: Flexo inks are designed to withstand abrasion and exposure to various chemicals to maintain print quality and readability on packaging materials.
- Compatibility with Anilox Rollers: Flexographic printing uses anilox rollers to transfer ink to the printing plate. Flexo inks need to be compatible with these rollers and ensure consistent ink distribution.
- Color Consistency: Flexographic inks are formulated to achieve accurate and consistent color reproduction, which is essential for brand consistency and attractive packaging.
- Low Odor: Some flexographic inks are designed to have low odor, which is especially important when printing on materials like food packaging.
In the making of Flexographic printing ink there are many factors involved but one of the most important of these is surface tension. Inks naturally want to flow to the higher dyne level. Proper surface tension configuration allows the most ink possible to be transferred to the substrate and ensures a full and even wet out.
