What's considered good mesh tension?Updated 3 hours ago
Good mesh tension is at least 20 newtons. Static frames will lose tension over time.There is nothing we can do about that. At a certain point, the mesh tension will be too low to create a good print. At that point, you can either recycle the aluminum frame and buy new screens or stack a bunch together on a pallet and ship out to get remeshed. You would pay to have them restretched and pay to have them shipped back. It’s a long process. Better mesh tension is closer to 25 newtons. Using frames like the ECO Frames makes re-meshing screens simple and easy to do in-house. If a panel gets too low in tension, pop it out and put in a new one. In 12 hours, you can degrease and get the screen ready for production. The best way to maintain high mesh tension is to use roller frames. While they have great mesh tension, you need to have a good knowledge about the frames because there is a maintenance barrier. To read the tension on the screens, you need a screen tension meter.
Proper screen tension is essential for sharp prints, accurate registration, and consistent results. As a general guideline, 20 newtons (N/cm) is considered the minimum tension for quality printing, while 25 N/cm or higher is ideal for most applications.
Traditional static frames naturally lose tension over time, and unfortunately there's no way to prevent it completely. As the mesh relaxes, print quality and registration can suffer. When a screen no longer holds adequate tension, you have a few options: replace it with a new screen, send the frame out to be re-meshed, or, if you're using a retension-able frame system, simply install a new mesh panel.
ECO Frames make replacing worn mesh quick and affordable by allowing you to swap out mesh panels in-house instead of replacing the entire frame or waiting for a re-meshing service. In 12 hours, you can degrease and get the screen ready for production.
For shops that demand the highest level of print consistency, roller frames are considered the gold standard. They allow you to re-tension the mesh as it relaxes over time, helping maintain excellent registration and extending the life of the screen. While they require a greater upfront investment and a bit more maintenance knowledge, they provide unmatched control over screen tension and print quality.
To accurately measure screen tension, use a tension meter (tensiometer). Regularly checking your screens will help you identify when tension has dropped below acceptable levels, allowing you to maintain consistent, high-quality prints throughout your production runs.
