Polyester Printing Mesh for Graphic and Digital Printing

Sept. 27, 2011 - PRLog -- General Introduction


Screen printing is a printing technique that uses a woven mesh (screen mesh)  to support an ink-blocking stencil. The attached stencil forms open areas of mesh that transfer ink as a sharp-edged image onto a substrate. A roller or squeegee is moved across the screen stencil, forcing or pumping ink past the threads of the woven mesh in the open areas.

Screen printing is also a stencil method of print making in which a design is imposed on a screen of silk or other fine mesh, with blank areas coated with an impermeable substance, and ink is forced through the mesh onto the printing surface. It is also known as silk screening or serigraphy.

Printing Material (Fiber Characteristics Chart)

Traditionally silk mesh was used for screen-printing, hence the name silk screening. Currently synthetic threads are commonly used in the screen printing process the most popular mesh in general use is made of polyester. There are special use mesh materials of nylon and stainless steel available to the screen printer

Fabric Construction

Fiber Type---is an important factor when choosing a fabric suitable for your application. Common considerations are working temperature, abrasion and chemical compability, which may include the PH range of your application.



Mesh Count---is the numbder of threads per inch in the direction of warp and weft of the fabric. The mesh count is identical in both warp and weft direction for Share Filtration's woven mesh.



Thread Diameter---is specified as the diameter of the thread in microns; Yarn sizes in both warp and weft directions are the same.



Mesh Opening---is the size or space between threads. The mesh opening is the result of the combination of the mesh count and yarn size. Mesh opening will determine the size or amount of material that will pass through the fabric


Introduction:
Polyester Screen Printing Mesh Fabric is one of the most advanced high-tech screen mesh products in 1990s for screen printing.

With high quality raw material of polyester yarn, advanced weaving machines from Swiss, well-educated workersl, Share Filtration produces and supplies superior quality polyester and polyamide bolting cloth for screen printing. We also have the most advanced testing instruments and technicians well trained to guarantee a reliable quality.

Monofilament Polyester Screen Printing Mesh(Low-elongation) Features:

Low-Elongation Monofilament Polyester Screen printing mesh is what we are producing now in a wide range of mesh counts(from 10T to 165T), and Share Filtration's polyester printing mesh offers significant advantages over the traditional monofilament polyester printing mesh:


Faster tensioning without damage to the threads
Improved fabric strength
Faster tension stabilization
Higher tension threshold and breaking point
Less tension loss during the stretching process
Faster turnaround time from the screen room to the pressroom
Improved registration due to stable tension
Faster Print Speeds

Screen Printing Mesh Applications:
CD/DVD Printing, Ceramic Decorating, Graphic Screen Printing (Glass Containers, Labels,Large Format UV Graphic, Small Format UV Graphic, Solvent Graphics, Tubes and Cartridges), Package Printing, Printed Electronics, Printing on Glass, Solar Cell Printing, Textile Printing, Tableware.


This could also help you trouble shoot if you run into problems with your print quality- you can look here to see if you are using the right mesh count. Here it is.
