Screen Printing or Silk Screening

Screen Printing Screen printing or silk screening is a printing technique particularly suited for flat or relatively flat surfaces. The heart of the process involves a fine mesh or screen that is tightly stretched around a rigid frame. The areas that are not to be printed are masked out on the screen. To create the print, the framed screen is positioned over the item to be printed along with a dollop of thick ink. A squeegee is then used to press the ink through the screen. The masked areas prevent ink from passing through, but the unmasked areas allow the ink to be imprinted on the material. The final step is to send the item on a conveyor belt through a heat-tunnel. This curing process ensures that the inks dry quickly so that they materials can be stacked or packaged. Properly cured inks will remain on the printed substrate even under harsh conditions. If more colors are desired in the final design, the process is repeated with different screens. Therefore, a design that requires four different colors would require four different screens. The screens are usually placed on a rotary press which allows the different color prints to be properly aligned or registered with each other. Some screen-printers have fully automatic presses that do not require any manual labor other than set-up and loading/unloading. There are a variety of ways that the screen can be masked. The most straightforward way is to apply masking fluid directly on the screen. This technique is suitable for simple one or two color graphics but is ineffective for more complex prints. For multicolor jobs, screen-printers often use photosensitive emulsions to create the masked areas. First, the design is created on a clear piece of plastic film. Meanwhile, a photosensitive coating is applied to the entire surface of the screen and then dried. The film is placed on the prepared screen and they are exposed to bright light. After a period of time, the exposed areas can be washed off the screen with water which makes the screen ready to print.
