Mesh-opening with SEFAR LFM 150/380-32 PW
Mesh-opening with standard high-modulus mesh 150/380-34 PW
With its reduced thread diameter – just 32 microns – SEFAR LFM has remarkably larger mesh openings and hence an increased amount of open area which offers some outstanding characteristics:
optimized mesh geometry
balanced, low elongation
strength for larger formats
modest loss of tension
Due to its improved mesh geometry, SEFAR LFM will maximize print results when using process, translucent, and other sensitive inks. In addition, SEFAR LFM delivers a more uniform ink deposit, finer color-value gradation, reduced risk of moiré, and sharp-edged fine lines and screen dots.
Getting to color on press quickly and increasing reproducibility on subsequent print runs is another quality feature of SEFAR LFM.

The greater the mesh elongation, the greater the loss in thread count. SEFAR LFM elongates less than existing screen printing meshes, which helps to maintain the thread count of the stretched mesh. That ensures better image resolution, increased print quality, and less risk of moiré effects. Because this mesh is subject to considerably less relaxation in tension, the same screen can be used more often and/or for longer print runs, which helps to reduce costs.
Special Sefar surface treatment streamlines stencil production, improves adhesion of the stencil material, and results in lengthening screen life on press.
