Screen printing, also known as silk screening, is one of the oldest and most versatile printing techniques. It involves pushing ink through a stencil (or mesh screen) to create designs on a variety of materials. This method is widely used for creating custom apparel, signage, and promotional products, offering durable and vibrant results.

Printing:
Place the screen on the substrate (e.g., fabric or paper).
Apply ink and use a squeegee to press it through the screen onto the surface.
Curing:
Heat-set the ink to ensure durability and adherence.
Finishing:
Perform additional steps like folding, cutting, or packaging as required.
