Mesh-opening withstandard high-modulusmesh 150/380-34 PW

Engineered with the large format printer inmind

Finer, stronger threads and larger mesh openings With its reduced thread diameter – just 32 microns –SEFAR LFM has remarkably larger mesh openingsand hence an increased amount of open area whichoffers some outstanding characteristics:

• optimized mesh geometry• balanced, low elongation• strength for larger formats• modest loss of tension

Your Benefits

SEFAR LFM is the large format solution

Exceptional print qualityDue to its improved mesh geometry, SEFAR LFM will maximize print results whenusing process, translucent, and other sensitive inks. In addition, SEFAR LFM delivers

a more uniform ink deposit, finer color-value gradation, reduced risk of moiré, andsharp-edged fine lines and screen dots.

Getting to color on press quickly and increasing reproducibility on subsequent printruns is another quality feature of SEFAR LFM.

Minimal elongation and modest loss of tensionThe greater the mesh elongation, the greater the lossin thread count. SEFAR LFM elongates less thanexisting screen printing meshes, which helps tomaintain the thread count of the stretched mesh. Thatensures better image resolution, increased printquality, and less risk of moiré effects. Because thismesh is subject to considerably less relaxation intension, the same screen can be used more often and/or for longer print runs, which helps to reduce costs.

Longer stencil lifeSpecial Sefar surface treatment streamlines stencilproduction, improves adhesion of the stencil material,and results in lengthening screen life on press.

SEFAR PET 1500Economical and high-quality printing results for professional demands

SEFAR PET 1500 is the popular mesh for virtually every screen printing application -large and small-format graphics, CDs, decorative tile designs, printed glass, sportinggoods, textile printing, and other industrial tasks.

Product Features

A reliable mesh that meets industry demands

Manufactured under start-to-finish process control, SEFAR PET 1500 features a wideproduct range, excellent stretching and tensioning properties, improved stenciladhesion, and increased exposure latitude—optimal conditions for quality screenprinting results.

Wide product range

SEFAR PET 1500 is available in both white andyellow fabrics, ranging from very coarse to ultra-finein different witdths up to 4m—providing just the rightmesh specification for every screen printingapplication.

Excellent stretching properties

SEFAR PET 1500 can be stretched to hightensions, and will maintain tension longer. Tensionloss between stretching and printing is low, andtension will remain stable over subsequent printruns.

Innovative surface treatment improveswettability and stencil adhesion

SEFAR PET 1500's advanced surface treatmentprovides improved mesh wettability characteristicsthat are required for indirect films, capillary films,emulsions or combined applications. In addition, theunique surface of SEFAR PET 1500 contributes toimproved stencil adhesion properties.

Unbeatable undercutting protection

Manufactured using Sefar's proprietary mesh dyingprocess provides a yellow mesh that has lightundercutting prevention to ensure sharp, saw-toothfree reproductions. Extended exposure latitudecompensates for minor deviations in exposure time,illumination intensity and distance.

Your Benefits

The right mesh for your application

SEFAR PET 1500 is a versatile and reliable screen printing mesh that improves yourproductivity and mesh quality, while reducing costs associated with time andmaterials.

Wide product rangeSEFAR PET 1500 has an expansive range of meshspecifications, making it possible for the screen printerto find the best mesh for their application.

Valuable stretching characteristics The strength of SEFAR PET 1500 allows screenprinters to work with high tensions, and experiencefewer mesh failures during the stretching process.Higher tensions on press allow for lower off contact,which prolongs screen life and improves color-to-colorregistration accuracy.

Longer screen life Because SEFAR PET 1500 also exhibits excellentdimensional stability and holds tensions longer, the lifeof the screen in production is prolonged and meshconsumption is lowered.

Increased resolution of fine graphic elementsThe SEFAR PET 1500 proprietary mesh dying processhelps to increase the exposure latitude of stencilemulsions. Wider exposure latitudes make it possiblefor screen printers to more easily expose and printhigh line counts, halftone gradations, fine lines, small

text and other intricate graphic elements.

Improved mesh wettabililty and optimum stencilsurfaceSEFAR PET 1500's innovative mesh surfacetreatment provides improved wettability and moreuniform emulsion distribution, and therefore increasedproductivity!

In addition, the increased stencil adhesion propertiesfirmly retain screen dots and fine lines, considerablylengthening stencil life.

The mesh retains this excellent adhesioncharacteristic even after multiple uses. Because of itsuniformity of the surface treatment, a majorimprovement of the reproducability in print, whenchanging screens have been achieved.

SEFAR PME provides the greatest possibledimensional stability

In addition to improved warp and weft balance andlow elongation properties, SEFAR PME wasengineered to display increased dimensionalstability in both the warp and weft directions duringthe printing process to help improve imageprecision and registration over long print runs.

SEFAR PME requires shorter exposure time

The specially engineered yarn allows screensstretched with SEFAR PME to expose faster thanstandard polyester meshes while maintaining verygood resolution characteristics.

SEFAR PME is quality certified for precisionapplications

All Sefar screen printing meshes are manufacturedto ISO 9001 standards—a prerequisite for manyindustrial manufacturing operations.
