High precision Screen Printing Mesh

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.

The screen printing mesh professionals use

SEFAR PET 1500 the most comprehensive range of screen printing mesh for an efficient and reproducible stencil production. It meets all the requirements for detail reproduction, homogeneity of face printing, print run consistency and registration accuracy in multi-color printing. The special SEFAR PET 1500 surface treatment aims to improve adhesion, good wettability and good antistatic properties. These features allow a high quality and efficient processing of all commercially available screen printing systems.

• Unsurpassed UV-light undercutting protection of yellow mesh
• Adhesion and preparation optimized mesh surface
• Reproducible mesh relaxation
• Good ink and paste release behaviour
• Good antistatic behavior thanks to Sefar antistatic treatment
• Wide standard range with high availability

YOUR BENEFITS

Screen / stencil maker benefit

• Sharp-edged reproduction of the artwork on the stencil
• Finest detail reproduction
• Homogeneous coating
• Easy capillary film application
• The tension drop is stable and low
• Process and product reliability
• Adhesive passes good through the mesh, therefore less problem in bonding the mesh to the frame
• Reduced susceptibility of dust
• Reduction of retouching time
• Optimizing of storage management
• Short delivery time
• High reliability ensures continuous production

Printer benefit

High reproducibility

Best edge definition in print

Extended screen life

High quality image reproduction

Better color to color reproduction

Good reproducibility of fine details

Uniform ink application

Maintaining of tightest color shade tolerances

Error-free and clean printing

Reduction of waste in the print process

Ensured continual delivery of stencils

Unlimited options of ink/paste film thickness

Eliminates mesh degreasing:

Degreasing remains unnecessary No =Cost savings =Less environmental burden

SEFAR PET 1500: uniform wetting Test:

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
• Printing on a black background This highly magnified picture shows clearly the difference of the ink deposit
• Mesh without surface treatment: uneven ink deposit, the background is partly visible

Polyamide Mesh

Info sheet

Nylon fabrics were the first monofilament synthetic fibres to be used for manufacturing screen printing meshes.Info sheet

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.
