The answer is yes, we can screen print on plastics. However, there are some important considerations to keep in mind before attempting this process. It is very important:
Firstly, not all plastics are created equal. Some plastics have a smooth surface that may be difficult for ink to adhere to, while others may have a textured or uneven surface that could affect the clarity of the printed design. It’s important to test different types of plastic beforehand to see which ones work best with your chosen ink and process.
Second, it’s crucial to properly prepare the surface of the plastic before screen printing. This includes cleaning and possibly treating the surface with a primer or adhesion promoter to ensure that the ink will adhere properly. If the plastic has any oils or residue on it, this can also affect how well the ink adheres and may result in a design that easily chips or peels off.
In addition, when screen printing on plastics, you’ll need to use specialized inks that are designed specifically for this purpose. These inks often contain additives that help with adhesion and durability on plastic surfaces. Make sure to carefully read the instructions and recommendations for use of these inks to achieve the best results.
