Recommended mesh count for printing:
Electronics(PCB): 36-140mesh/cm(91-355mesh/inch)
Glass: 77-120mesh/cm (196-305mesh/inch)
Ceramic: 32-140mesh/cm (80-355mesh/inch)
CD/DVD: 140-165mesh/cm (355-420mesh/inch)
Applique: 77-120mesh/cm (196-305mesh/inch)
Packaging: 100-140mesh/cm (255-355mesh/inch)
Metal (signs): 100-140mesh/cm (255-355mesh/inch)
Plastic (PVC/PET/PC): 100-140mesh/cm (255-355mesh/inch)
Dyeing: 20-53mesh/cm (50-135mesh/inch)

The following should be considered when choosing a mesh:

1. Mesh count
Mesh count is simply stated the number of threads of screen mesh in a given inch(or cm). Different meshes yield different results and the variety allows the printer to control factors such as amount of ink deposited.

2. Thread diameter
Diameter of the thread of which the mesh fabric is made. Thread diameter has an influence on ink volume and mesh tension together with mesh count. Different thread diameters for same mesh count produce different precision of picture.

3. Mesh opening (or aperture)
Distance between two threads. It's important to relate mesh opening, cause if the ink granule has a larger diameter than mesh opening, it will block the hole in printing. Normally mesh opening should be 3-4times of the largest diameter of ink granule.

4. Thickness (mesh thickness)
S type is very thin, mainly used in high definition and even printing stock, such as DVD.
T type is the medium, is most widely used, from fabric to PCB.
HD type is thick one, mainly used on gross printing stock, such as carpet.

5. Colour
Normally are yellow and white. White thread reflects the blue ray of light in exposal, yellow thread absorbs it. So yellow mesh needs a longer exposal and produces a better picture.

6. Weave: normally Plain Weave and Twill Weave. Plain Weave allows a larger mesh opening, having a larger contacting area with printing stock, produces a better ink value. That��s why plain weave is the most used.

7. Maximum Tension (N): the maximum tension when mesh is stretched, mesh will break or deform when tension is larger than this value. It varies regarding stretching machine and size.

8. Material:
Normally three:
Polyester Mesh (PET): Good dimensional stability, high tension, low elongation, good weather resistance, allows a lower ink value than Nylon Mesh. Suitable for process printing.
Nylon Mesh (PA): High rebound resilience, excellent abradability, some alkali resistance, high mechanical strength, allows a higher ink volume. High elongation, low dimensional stability, easy to be affected by weather and temperature, not suitable for process printing.
Stainless Steel Mesh: High tension and strength, good dimensional stability, low elongation and rebound resilience, easy to break and get loose. Suitable for process printing. Expensive.Polyester mesh is the most used one.
