Flexographic ink solvents: Classification, properties, and usgae tiptips

Flexo printing ink (flexographic printing ink) is one of the popular printing technologies in the packaging industry, especially for materials such as woven PP. However, for the ink to work effectively on materials such as woven PP, the use of ink solvent is very important. Solvents help the ink to easily adhere, dry quickly and produce high quality products. In this article, we will learn about Flexo printing ink solvents when printing on woven PP.

What is Flexo printing ink solvent?

Flexo printing ink solvents are liquids used to dilute or adjust the viscosity of the ink, helping the ink to easily transfer to the surface of the material without affecting the quality of the print. Solvents help the ink to dry easily, save time and optimize production efficiency.

The role of solvents in Flexo printing ink (woven PP printing)

Adjusting viscosity: Flexo printing ink has a fairly thick viscosity, so solvents are used to adjust the viscosity of the ink to suit the printing speed and surface properties of woven PP.

Adhesion: Woven PP is a slippery material, so solvents help improve the adhesion of ink to the material surface, ensuring clear and sharp print quality.

Quick drying: Using the right solvent helps the ink dry quickly, prevents smudging, and helps improve production efficiency.

Reducing evaporation: Solvents also help reduce evaporation of ink, helping the ink adhere longer to the woven PP surface without fading or losing durability.

Common solvents in Flexo printing ink on woven PP

In the process of mixing Flexo printing ink, there are some commonly used solvents depending on the requirements and characteristics of the printing ink and woven PP material:

Isopropyl Alcohol (IPA): This is a common solvent, helping the ink dry quickly and has good solubility. IPA is often used to dilute the ink and clean the printing machine.

Water solvent: In the case of Flexo printing ink using a water-based ink system, water solvent will be used to adjust the viscosity and help the ink adhere to the woven PP without affecting the color of the ink.

Solvent-based ink: Solvents such as xylene, toluene are often used in solvent-based Flexo printing ink. These solvents help the ink to easily coat the surface and have high durability.

How to choose the right Flexo ink solvent for woven PP

Consider the material properties: Woven PP has a smooth surface and is difficult to adhere to, so it is necessary to choose a solvent that helps the ink adhere well and dry quickly.

Check compatibility: Make sure the solvent you choose does not damage the material of the woven PP, avoiding the ink being smudged or uneven in color.

Choose a solvent with high stability: For the printing process to be stable and effective, the solvent needs to be stable for a long time, helping to maintain the quality of the print over a long period of time.

Benefits of using Flexo ink solvents properly

Increase production efficiency: Solvents help the ink to be easily applied to woven PP materials, minimizing waiting time and increasing productivity.

Reduce costs: Using solvents properly will help save ink, reduce costs for the production process while still ensuring print quality.

Improve print quality: Mixing solvents properly will help the ink adhere evenly, dry faster and be sharper, thereby improving print quality.

Conclusion

Flexo printing ink mixing solvent (woven PP printing) plays an important role in ensuring the quality and efficiency of the printing process. Choosing the right type of solvent helps adjust viscosity, improve adhesion and dry ink quickly, thereby improving print quality and production productivity. Pay attention to choosing the right solvent for each type of ink and the requirements of each printed product to achieve optimal efficiency.
