What’s mean Screen printing?
Screen printing 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 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 prior to the invention of polyester mesh. 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. There are also different types of mesh size which will determine the outcome and look of the finished design on the material.
Screen printing may be the oldest and most practical printing technique dating back to ancient times. There are hypotheses that silk screen printing’s origins started in China at least the 12 century B.C. when silk began to be produced there. Silk printing may have originated not far from the Mediterranean Sea between Mesopotamia and Phoenicia according to available historical facts.
There are a number of archeological finds and historical studies that indicate that the Phoenicians found a way to reproduce patterns on fabrics using techniques uncommon to those used today.
Human Hair Stencils Advance Screen Printing
However, they can be credited with pioneering a system of image duplication by using stamps to reproduce simple patterns. The method was later improved in Japan to a printmaking technique that created sharp-edged images using a stencil and a porous fabric, known as screen printing, or serigraphy. The Japanese used simple stencils which were glued onto a screen made of human hair that was stretched over a wooden frame.
Screen Printing Improved During The Middle Ages
This printing technique was then further improved throughout the Middle Ages and became widespread in Europe. The screen printing process that we know of today emerged in the early 1900s when a man from Manchester, England, Samuel Simon, received a patent for using a silk screen fabric as a printing screen. Another first in screen printing history. Simon patented this process of printing through a silk screen, which guaranteed a higher tensile strength and better size stability. Simon’s process also used rubber blades, or squeegees, to push the ink through the screen which is still used today. The invention was coined the term silk screen printing.
War Brings Screen Printing To America
It was not until the First World War that screen printing took off in America. The process was used for printing flags and banners. The use of photographic stencils at this time made the process more versatile and encouraged wide-spread use. The actual use of silk for screens was discontinued in the mid-1940s during the Second World War because of its use in the war effort. Since then a polyester material has been used for the screen mesh and other improvements have been made in the presses, inks, and chemicals used. Otherwise the same basic screen printing process patented by Simon is still used today.
