Which technique is most commonly used in porous printing methods?

Screen printing is the technique most commonly used in porous printing methods because it relies on a mesh screen to transfer ink onto the substrate. This method works effectively with porous materials such as textiles, paper, and cardboard, allowing ink to penetrate the surface and adhere well. The process involves creating a stencil on the mesh, where ink can pass through only in the designated areas, making it ideal for producing vibrant designs on fabrics and other absorbent surfaces.

This method is particularly popular in the production of t-shirts, posters, and promotional materials due to its versatility, ability to produce bold colors, and capacity for handling multiple designs at once. It is also favored for its low setup costs and the ease with which small production runs can be executed, solidifying its position as a staple in both commercial and artistic applications.
