What is a Good Tension for Screen Printing?

Achieving the correct mesh tension is fundamental to successful screen printing. It directly impacts print quality, registration accuracy, and the overall longevity of your screens. Generally, a "good" tension for screen printing falls within the range of 18-25 Newtons per centimeter (N/cm). However, the ideal tension can vary based on several factors.

Here's a breakdown of key considerations:

• Mesh Count: Higher mesh counts (for finer detail) usually require slightly higher tension than lower mesh counts (for thicker inks or block images).
• Screen Size: Larger screens may need slightly higher tension to maintain even distribution across the frame.
• Mesh Fabric: Polyester meshes are generally more stable and can hold higher tensions compared to nylon.
• Frame Type: High-quality, rigid frames are essential for holding tension effectively without warping.

While 18-25 N/cm serves as a good guideline, it's essential to consult your mesh supplier's recommendations and use a tension meter to accurately measure your screen tension. Too low of a tension can lead to blurry prints and poor registration, while overly tight mesh can cause premature mesh failure or screen damage. Maintaining consistent tension across all your screens is also vital for repeatable and accurate results.
