How To Measure Screen Tension With and Without a Tension Meter

Proper screen tension is key to clean, consistent, high-quality prints. Loose screens cause issues like poor registration, ink spatter, and the need for more squeegee pressure. Tighter tension gives brighter prints with less effort. Most mesh can handle 25 Newtons or more. Although it’s suggested to use a proper device to measure tension, there are ways to measure this with and without a device.

How to Measure Tension Without A Tension Meter

It's recommended to use a tension meter for the most accurate measurements. However, these manual checks can help you identify if the tension is significantly off.

• Sound Test: Gently tap the center of the mesh. A tight, snare drum–like sound means the tension is good. A dull, bass-like sound indicates low tension and that the mesh isn’t stretched tightly enough. Try tapping near the center and corners—uneven tension is a silent killer.
• Visual and Tactile Assessment: Examine the screen for wrinkles, loose spots, or uneven tension. The mesh should feel tight and consistent when touched. Prints that look fuzzy or edges that aren't clean are often a tension issue. Ink flooding or “ghosting” around letters also points to tension loss.
• Push Test: This can be done with a credit card or even a squeegee. Push down slightly in the middle of the mesh. If it sags more than 1/8" (3 mm), it's likely too loose. A tight screen barely flexes when pushed.

How to Measure Tension With A Tension Meter

Using a Tension Meter will give the most accurate results to dial in your screen tension. There are many devices on the market to choose from, but understanding the importance of one is crucial when selecting a device.

To test screen tension with a tension meter for screen printing, lay the screen down on the frame with the print side facing up, place the meter on the screen's print side, and measure the amount it gives under its own weight. Ensure the screen is flat and level, and measure across both the warp (vertical) and weft (horizontal) directions, checking multiple points to ensure uniformity. 

When using roller frames, which are intentionally soft in the corners and edges and hold tension in the print areas, metal or aluminum frames will also hold tension in the print area, as well as the corners and edges.

Key Tips for Measuring Screen Tension:

• Clean Screens First – Dirt or residue can affect readings.
  
  
• Use Bidirectional Meters – Higher-end meters measure both directions at once.
  
  
• Calibrate Often – Regular calibration keeps readings accurate.
  
  

Check Regularly – Tension drops over time, especially after reclaiming or heavy use. Don’t leave screens in direct sunlight or extreme heat—heat warps frames and loosens mesh.
