It uses a woven mesh to support an ink-blocking stencil. The attached stencil has open areas of mesh that transfer ink. As a squeegee is moved across the screen stencil, ink is forced through the mesh openings, creating an image on the apparel. Silk screen printing allows up to 4 colours, and the 4 colours will come together to form a complete picture with a range of colours.

Advantages of Silkscreen:

• Most cost-efficient printing method for bulk quantity. Once a silk mesh template is created, the template will be reused and the only additional cost incurred is the ink required, making it cost efficient.
• Durable – vibrant and opaque finishing that can withstand many washes

Limitations of Silkscreen:

• Expensive for small orders
• Every color of printing requires a new screen. Therefore, every color of printing adds on to the start-up costs. Therefore, can get very expensive for complex design printing with many colors.

This method is most advantageous when:

• Your order quantity is high
• You have a tight deadline and need the apparel ASAP
• Design contains less than 4 solid colours

Cost of silk screen printing depends on:

• Number of colours
• Size of print
• Number of print positions
• Quantity of the order
