Because polyester mesh is best for high quality screen printing…
However screen printers need to do extensive R&D to unearth solution for their problems. However, to solve the registration miss–match problem, Polyester mesh is now being widely used. Polyester also has different grades. Polyester mesh is available in wide range from 6 mesh/cm to 180 Mesh/cm and various widths, in both white and yellow colours.
At excessive tension levels, the thread reaches to its plastic deformation point, and the screen will be stiff with no longer capacity to hold tension. However, it has been outshined by a new development in thread technology (High Module), which enables to bear the high tension with Low-Elongation for better and consistent print quality.
Polyester mesh is the preferred choice of the high end industries. i.e. electronics industry (PCB, membrane switches mfrs), CD printing, graphic printing, automotive decals, ceramic decals, tiles, glass, industrial labels, textile industry (garments and apparels, tag printing), Package Printing …even for halftone and fine printing like small micro letters, logos in a visiting card.
• High tensile and dyed fabric
• Low elongation
• No deformation of fabric
• Fast & good tensioning
• Quick lifting off fabric after squeegee lifts
• Fast ink release, Easy peel off
• Special fabric surface.
• Good Dimension stability
• Faster stabilisation
• Good durability
• Good resistance to acids & alkalis
• No water absorption
Ink savings: Low elongation means savings in ink, if it is used as per the specifications, instructions and right advice from suppliers.
Less consumption: It retains set tension level, print after print and job after job. This way, minimal distortion enables printers to obtain the most consistent results even after long printing runs. It not only improves productivity but also help reduce rejections.
High tension: Can be stretched to high tensions and maintain tension longer. Tension loss between stretching and printing is low and tension will remain stable over subsequent print runs. Higher tensions on press allow for lower off contact, which prolongs screen life and improves colour-to-colour registration accuracy. It also increases production speed.
Special Surface Treatment: Innovative mesh surface treatment provides improved wet ability and more uniform emulsion distribution. This treatment also ensure strong Adhesion: The mesh has an excellent screen making capabilities with outstanding resolution, resulting in a powerful adhesion to the photosensitive emulsion and tremendously increases the life of the mesh. The increased stencil adhesion properties firmly retain screen dots and fine lines, considerably lengthening stencil life.
• Less choke up, less ghost image
• Easy to clean (after washing)
• Easy ink flow
• Consistent result
• Makes screen strong
• Preferred for good reproduction of minute details, sharp results
• Good for registration accuracy
• Good for high speed printing
• Increase in quality of job, improved registration due to stable tension
• Squeegee movement: silky and smooth
• High emulsion adhesion
• Stable printing dimensional accuracy
• Faster turnaround time from the screen room to the pressroom (Less tension change over time after tensioning)
