Traditional Screen Printing
Traditional screen printing, also known as silk screen printing, is a widely used method for applying designs, including numbers, onto various surfaces, including jerseys. The process involves creating a stencil, typically made of a fine mesh screen stretched tightly over a frame.
Areas of the stencil that are not intended to be printed are blocked off, allowing ink to pass through only the desired areas onto the fabric.
Materials Needed To Print Numbers Through Traditional Method
- Screens: Fine mesh screens made of silk or polyester are commonly used. The mesh count depends on the level of detail in the design.
- Squeegees: These are tools used to force the ink through the screen and onto the fabric. They come in various sizes to accommodate different screen sizes and ink types.
- Inks: Screen printing inks come in various formulations, including water-based, plastisol, and discharge inks. The choice of ink depends on the fabric type and desired outcome.
- Emulsion: Emulsion is used to create the stencil on the screen. It is applied to the screen and exposed to UV light through a film positive containing the desired design.
- Film Positive: A film positive is a transparent sheet with the design printed on it. It serves as a stencil when exposed to UV light during the emulsion process.
- Exposure Unit: An exposure unit is used to expose the emulsion-coated screen to UV light, transferring the design onto the screen.
Step-by-Step Process To Do Perfectly
- Preparation: Stretch the screen tightly over the frame and coat it evenly with emulsion. Allow the emulsion to dry completely.
- Film Positive Preparation: Print the desired design onto a transparent film positive using a printer or have it professionally produced.
- Exposure: Place the film positively onto the emulsion-coated screen and expose it to UV light in an exposure unit. The UV light cures the emulsion except where blocked by the design on the film positive.
- Washing Out: Wash out the uncured emulsion using water, leaving behind the stencil on the screen.
- Printing: Place the screen onto the jersey and apply ink to the top of the screen. Pull the squeegee across the screen, forcing the ink through the stencil and onto the fabric.
- Curing: Once the ink is applied, cure it using heat to ensure durability and wash resistance.
