Printing Process
  1. Screen Printing
    1. How it works
      1. A screen is made from a piece of porous, finely woven fabric (polyester/ nylon) streched over a wooden of aluminium frame.
        1. A stencil is used which blocks off areas of the screen with a non-permeable material.
          1. Stencil is a negative of the image to be printed, so the open spaces are where the ink wil appear.
          2. Advantages
            1. Stencils are easy to produce using Photo-emulsion technique.
              1. Versatile- can print on virtually any surface
                1. Economic for short, hand-produced runs.
                2. Disadvantages
                  1. Difficult to achieve fine details (photographic screens able to produce fine detail)
                    1. Prints require long drying time.
                    2. Materials used
                      1. Paper
                        1. Boards

                                            2. Digital Printing (think of laser printing)
                                              1. How it works
                                                1. Use laser guided electrostatic energy to transfer tone powder obnto paper in the form of text and images.
