Smartmesh from Murakami is one of the best production tools you can use in screen printing. It is essential to consistent printing and non stop production.  After all, the last thing that makes your screen print product is the mesh that prints it. The better the mesh the better the print. 
Properties:
Excellent registration Quality – Precision woven with proprietary threads and manufacturing methods to assure you of the highest quality mesh possible.
Balanced warp and weft threads yield balanced stress/strain curves and helps create a mesh that withstands multiple forces that occur during the print process.
Smartmesh is a low elongation mesh – it also resists accumulated elongation as the print progresses and the forces of the squeegee warms up the mesh.
Woven with precise square openings which helps control moire.
Mesh above 280 threads per inch is surface treated to improve ink flow and more complete ink transfer to the substrate.
High retained tension properties helps Smartmesh avoid losing excessive amounts of tension common on inferior mesh.  Static stretch and glue frames retain workable tensions for a longer printable screen life.
