A Screen-printing machine, on the other hand, is vastly different. In essence, it is a form of stenciling. It is an actual mesh screen where your artwork is chemically transposed onto the screen. Ink is then physically pushed through the mesh, in the form of a design. Each screen only uses one ink color, therefore many customers typically limit their artwork to less than three colors to avoid added screen costs. Screen-printing inks can be water-based, but the most commonly used are called plastisol, which give a plastic-like feel.  Screen-printing is still widely used, but it is most well served for specific purposes and mass quantities.  If your t-shirt artwork is very simple, and multi-color photos or details are not important for your purpose, then screen-printing may be a more reasonable choice for you.
