Screen printing is a printing technique that involves pushing ink through a stenciled mesh screen to create a printed design. It is widely used for printing on various substrates, including fabric and paper, and is known for its versatility and vibrant results. The process typically involves placing a mesh screen over the material, applying ink, and using a squeegee to push the ink through the screen. This method is popular in the textile industry for creating custom designs and is valued for its ability to produce high-quality prints.
