Screen printers are professionals who use a technique called screen printing to create designs on various surfaces, such as fabric, paper, and plastic. This process involves pushing ink through a mesh screen that has a stencil of the desired design. Screen printing is popular for making custom t-shirts, posters, and other promotional items. The screen printing process can be done manually or with the help of machines. Screen printers often work in shops or studios, where they prepare screens, mix inks, and operate printing equipment. This method is valued for its ability to produce vibrant colors and durable prints, making it a favorite in the apparel and advertising industries.
