Screen printing is a popular and versatile printing technique that involves transferring ink onto various materials using a mesh screen. It has a rich history, originated in China around the 10th century and quickly spread to other parts of Asia, Europe, and the Middle East. Initially, silk fabric was used as the screen material; hence, the name "silk printing." However, modern variations now employ synthetic meshes like polyester.
Screen printing involves several essential steps. First, a stencil or template is created by blocking out areas on the screen mesh that should not be printed. The screen is then placed on top of the material to be printed, such as fabric, paper, plastic, or metal. Ink is poured onto the screen and evenly spread across the stencil using a squeegee or rubber blade. The ink passes through the unblocked portions of the screen onto the material beneath, creating the desired design or pattern.
