Which of the following methods uses a screen to block out areas where color should not appear?

Screen printing is the method that utilizes a screen to block out areas where color should not appear. In this process, a stencil is made on a mesh screen, allowing ink to pass through only in the desired areas to create the printed design. This technique is widely used in various fields, including textiles and wall coverings, because it allows for precise control over the application of colors and patterns. By using different screens for each color, designers can layer multiple hues to achieve a complex design while ensuring that color is applied only where intended.

Other methods, such as yarn dyeing and transfer printing, do not utilize a screen to block out non-color areas. Yarn dyeing involves coloring the yarn before it is woven into fabric, which does not require masking; instead, it relies on the inherent properties of the dye interacting with the fibers. Transfer printing involves transferring a printed design from a substrate onto a material, often requiring the applied heat to activate the ink, but it also does not utilize a screen to achieve a blocked effect. Drawstring printing is not a recognized method in the context of color application and does not relate to blocking areas where color should not appear.
