Sefar are manufactures of a wide range of high-quality precision, Polyamide and Polyester mesh for screen printing, as well as pre-coated mesh (SEFAR PCF) for printing on CDs and DVDs.
Polyester is now the most widely used screen-printing mesh as it fulfils a wide range of criteria. As a high modulus mesh, polyester can be highly stretched and still hold its tension. Sefar mesh is available in an extremely wide choice of mesh numbers and thread diameters, suitable for printing fine line art and half-tone images. Our polyester products range from the universal SEFAR PET 1000, the new SEFAR PET 1500 (soon to replace pet1000) to SEFAR PET 1000 OSC (designed for optimal results with UV inks).
We also offer SEFAR VARIO, a specially developed
for the automotive industry to print car rear windscreens.
SEFAR PET 1000
SEFAR PET 1000 is the most popular mesh on the market as it is high quality, very reliable and economical
Excellent process reliability because of high reproducibility and durability
Very Good anti-static properties
Wide product range
Excellent Mechanical and chemical resistance
High tensile strength
Minimal loss of tension
Equal elongation in warp and weft
Reduced minimum snap-off distance
Excellent protection against under-cutting
SEFAR PET 1500 (NEW)
SEFAR PET 1500 Is a high-quality, economical screen printing mesh, which has a special surface treatment giving the following benefits:
Eliminates mesh degreasing:
Degreasing remains unnecessary No =Cost savings =Less environmental burden
SEFAR PET 1500: uniform wetting
Rinsing with a dyed water shows clearly the difference in the wetting behaviour
Of the mesh
Mesh without surface treatment: gives uneven wetting
Tape Test: An adhesive tape is fixed across the stencil Mesh without Surface treatment, parts of the emulsion are remaining on the tape
SEFAR PET 1500: No emulsion on adhesive tape Improved adhesion of stencil material Optimal retaining of screen dots and fine lines Considerable prolongation of stencil life
Improved printing results
Even and constant ink deposit
High-quality printing results
Homogeneous ink deposit

Nylon fabrics were the first monofilament synthetic fibres to be used for manufacturing screen printing meshes.
Nylon fabrics are extremely strong, which makes them very suitable for printing abrasive substrates like ceramic and reflective/fluorescent inks. The high elasticity of this fabric makes it easier to print onto uneven substrates e.g. Packaging, 3-D objects. The polyamide range which includes SEFAR PA 1000 - an elastic nylon mesh for use on uneven substrates, and SEFAR PA 2000 - an even more abrasive resistant fabric for extremely very long print
runs. The excellent properties of both fabrics make them suitable for the printing of 3-D objects and ceramics.
