Furthermore, rapid silk screen printing is highly versatile, as it can be used on a wide range of materials and surfaces.
The Process of Rapid Silk Screen Printing
The process of rapid silk screen printing involves several steps that ensure accurate and precise prints. The first step is to create the stencil by coating the screen with a light-sensitive emulsion and exposing it to UV light with a design transparency. This hardens the emulsion in the desired areas and leaves the rest soft and washable.
Preparing the Screen
Before applying the emulsion, the screen needs to be properly prepared. This involves cleaning it thoroughly to remove any dust or residue that may affect the print quality. Once the screen is clean, it can be coated with the emulsion using a scoop coater. The emulsion should be applied evenly and with the appropriate thickness for optimal results.
Exposing the Screen
Once the emulsion is applied, it is time to expose the screen to UV light. This is done by placing the screen on a light table or using a specialized exposure unit. The design transparency is placed on top of the screen, and the UV light is turned on for the required exposure time. The light hardens the emulsion in the exposed areas, creating the stencil for printing.
Washing Out the Unexposed Emulsion
After the screen is exposed, it needs to be washed out to remove the unexposed emulsion. This can be done using a pressure washer or a gentle stream of water. Care must be taken not to wash away the hardened areas of the stencil. Once the unexposed emulsion is washed out, the screen is ready for printing.
Applying the Ink
With the screen prepared, it is time to apply the ink. A squeegee is used to push the ink through the open areas of the stencil and onto the substrate. The squeegee is held at a 45-degree angle and moved across the screen with even pressure. This ensures that the ink is evenly distributed and results in a clean and crisp print.
Drying and Curing the Print
After the ink is applied, the print needs to dry and cure. This can be done through air drying or using a heat source, such as a conveyor dryer or a heat press. Proper drying and curing are crucial to ensure that the print adheres well to the substrate and maintains its color and durability over time.
