Screen printing is a method of printing in which ink is pushed through a stencil or mesh screen onto a substrate such as fabric, paper or metal. The stencil or screen is created by blocking off certain areas of the screen to create the desired image or design. The ink is then pushed through the open areas of the screen onto the substrate. It is a popular method for printing t-shirts, posters and other items in large quantities or digital cameras, which are used to create a printed image. This is in contrast to traditional printing methods such as offset printing, in which a printing plate is used to transfer ink to paper. Digital printing is often used for short-run printing, such as for brochures or business cards and can also be used for on-demand printing such as for printing photos or personalized products. Some examples of digital printing technology include inkjet and laser printing.
