Screen printing is a versatile and highly customizable printing technique. It is ideal for a range of mediums, from fabrics to glass and wood, and it can be used to create a variety of color options. In addition, this method provides a heavy ink coverage that offers enhanced durability and is ideal for designs that require high levels of detail.
To start the process, a printer must prepare a screen for printing. This is done by coating the screen with emulsion and using a scoop coater to spread it evenly across the entire surface of the screen. Next, the printer must image the screen. This can be accomplished in a number of ways, with the most contemporary method consisting of transferring a stencil onto an acetate or Mylar film sheet and then exposing it to UV light. The emulsion in the area of the stencil that was exposed to the UV light hardens, leaving a stencil through which ink can be applied.
Once the stencil is created, a printer must wash the screen thoroughly. This is important, as a poorly washed screen will not produce an accurate or durable print. The most common way to wash a screen is with a spray hose, though some printers also use rubbing alcohol and other methods. After the screen is washed, it must be allowed to dry completely before it can be reused.
When the screen is ready to be printed, a printer will load it with a shirt or other item and place it on a platen (a platform that holds items to be printed). The printer will then clamp the screen down so it is secure. A rubber blade, known as a squeegee, will then be used to push ink through the open area of the stencil on the screen.
For multi-colored or layered prints, the printer will need to create separate screens for each color. Once the screen has been printed, the ink will need to be washed off with water to prevent the stencil from deteriorating. Inks and other additives can be used to ensure the colors remain vibrant and resistant to fading, cracking, and scratching.
