Polyester Screen Printing Mesh

Screen printing is a printing technique where a polyester mesh is used to
transfer ink onto a substrate, except in areas made impermeable to the ink by a
blocking stencil. A blade or squeegee is moved across the screen to fill the
open mesh apertures with ink, and a reverse stroke then causes the screen to
touch the substrate momentarily along a line of contact. This causes the ink to
wet the substrate and be pulled out of the mesh apertures as the screen springs
back after the blade has passed. One color is printed at a time, so several
screens can be used to produce a multicoloured image or design.
There are various terms used for what is essentially the same technique.
Traditionally the process was called screen printing or silkscreen printing
because silk was used in the process. It is also known as serigraphy, and
serigraph printing. Currently, synthetic threads are commonly used in the
screen printing process. The most popular mesh in general use is made of
polyester.
