How to improve the adhesion of UV universal printer?

To enhance the UV printer adhesion, you can try the following methods:

1. Opt for high-adhesion UV inks: Choose UV inks that specifically enhance adhesion. These inks have stronger adhesive properties, making them more suitable for adhering to various materials.

2. Optimize the selection and use of UV lamps: Ensure the use of UV lamps that are compatible with the UV inks to achieve the best curing effect. UV lamps that are suitable can provide enough UV energy to fully react and fix the chemicals in the ink onto the material.

3. Adjust printing parameters: By adjusting parameters such as printing speed, layer thickness, and printing temperature, you can optimize the printing process for better adhesion. Proper parameter settings ensure even ink distribution on the material and thorough curing.

4. Use primers or coatings: Apply a layer of primer or adhesion promoter to the material surface before printing. These coatings can fill in minor imperfections on the material surface and improve the adhesion of UV ink.

5. For materials that are difficult to adhere to, use suitable surface treatment techniques such as sanding, sandblasting, or chemical treatment to improve surface roughness and wettability, thereby enhancing the adhesion of UV ink.

By selecting appropriate UV inks, optimizing the use of UV lamps, adjusting printing parameters, using primers or coatings, and performing material surface treatment, you can enhance the adhesion of UV printers, ensuring that the printed output adheres more securely to the materials.
