What is Screen Printing?

#Screenprinting is a printing technique whereby a 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.

Screen printing is also a stencil method of print making in which a design is imposed on a screen of polyester or other fine mesh, with blank areas coated with an impermeable substance.

Ink is forced into the mesh openings by the fill blade or squeegee and by wetting the substrate, transferred onto the printing surface during the squeegee stroke.

As the screen rebounds away from the substrate the ink remains on the substrate. It is also known as silk-screen, screen, serigraphy, and serigraph printing.

One color is printed at a time, so several screens can be used to produce a multicolored image or design.

La #serigrafía es una técnica de impresión empleada en el método de reproducción de documentos e imágenes sobre cualquier material, y consiste en transferir una tinta a través de una malla tensada en un marco.

El paso de la tinta se bloquea en las áreas donde no habrá imagen mediante una emulsión o barniz, quedando libre la zona donde pasará la tinta.

El sistema de impresión es repetitivo, esto es, una vez que el primer modelo se ha logrado, la impresión puede ser repetida cientos y hasta miles de veces sin perder resolución.
