Screen printing is also called serigraphy or silk screen printing. Many artists use screen printing for large formats. One advantage is that you can print on different kinds of substrates as canvas, plastic, or wood.
Screen printing is a printing technique based on the fact that color, using a squeegee, is pressed through a thin fabric that is clamped in a frame. Templates cover those portions of the fabric that will not let go through color. You make the template like this:
- The original is copied to a transparent film.
- The fabric in the frame is prepared with a photosensitive emulsion.
- The film is superimposed on and illuminated with ultraviolet light.
- The emulsion is flushed with water in the fields where color will come through.
You can only print one color at a time, but by printing new layers of color on the same paper, the final image can have infinite many colors, either created with grids or with full color.
