Tension of your mesh is measured in “Newtons”, or more particularly, Newtons per centimeter. To measure tension, industrial filter mesh a weighted Tension Meter is rested on the fabric and the deflection (how much the fabric “gives”) is denoted by number. For instance, 25 Newtons is a good tension for garment printing.
To find out the tension of a particular screen, lay the display on a flat surface with the print facet (mesh facet) up. Looking at the screen from the highest (the slim aspect), place the meter in the center of the display screen so as to see the face of the meter. The needle will level to the number that will correspond to the tension of the mesh from aspect to side.
Now, transfer to the facet of the display (lengthy side) and place the meter so you can see the face. This can let you know the tension of the mesh from top to bottom. The ideal tension will likely be within the 25. As much as the 35 Newton vary. There are special high tension mesh products accessible, however for garment printing, I personally feel these higher tensions are a little bit of overkill and pointless. And, high tension mesh could be very difficult to make use of when printing by hand on a guide press.
As a rule of thumb:
– 25 Newton mesh will provide you with an excellent tension for industrial filter mesh all types of printing
– 15-20 is acceptable
– 10 Newtons and beneath, your screen needs to be re-stretched
A tension meter will value approximately $500.00 and it’s not a required product if you end up first getting began, however ought to be on your want listing. If you happen to choose to use retensionable frames, a tension meter is absolutely needed to achieve proper mesh tension during the stretching process.
Low Tension
So what’s the massive deal about having screens with correct tension? There are two issues that may happen when you utilize screens with too gentle mesh. These are (1) fabric wave, and (2) mesh release.
Fabric wave means, as you apply strain and pull or push the squeegee throughout the display and shirt, a small wave of display mesh could type in entrance of the squeegee blade. On the underside aspect of the screen, this wave of fabric may fill with ink as it passes over the image, and then smear ink onto the garment when the squeegee reaches the sting of the graphic.
The more frequent problem is mesh launch. Printing with the preferred methodology of off contact, the one place the display physically comes into contact with the garment is along the sharp edge of the squeegee blade. In case your display screen mesh is too tender, coustic mesh the mesh won’t release from the garment as you pull or push the squeegee across the image. When the mesh does release, usually when you lift the screen, the ink on the shirt will strive to carry onto the display screen mesh, inflicting a rough end to your print.
On a multi-shade job, soft mesh will follow the earlier colors on the shirt, and the ink picked up will start to build up on the backs of your subsequent screens. Briefly order, your prints will start to seem muddy around the edges and where colours touch within your picture.
When printing dark garments, poor display tension can be doubly troublesome. The ink from the white underbase print is pulled up with the display screen, and then flash cured into that position. My greatest analogy is seeing a thousand little mountain peaks standing up on the shirt. Under a microscope, the surface would look just like the Alps. When colours are printed on high, the print feels very tough, or worse, lots of of tiny white specks present throughout the print area where the white underbase peeks by means of the colours.
To recap, when a print feels rough, it is almost always caused by a screen with poor tension. (I get this phone call from display screen printers all the time!) A tight display provides you with a crisp, sharp picture.

And on a handbook press, a tight screen will trigger far much less printing fatigue throughout the process.
