What Is Screen Printing and How Does It Work?

Screen printing is the oldest and most established method of printing designs onto fabric. It is the default method for large uniform orders, branded merchandise and band T-shirts, and for good reason. At scale, no other method produces as consistent a result at as low a unit cost.

How It Works

Each colour in a design requires a separate stencil (called a screen). The screen is a fine mesh stretched over a frame. The stencil blocks ink from passing through the mesh except where the design element appears.

The screen is positioned over the garment. A thick, opaque ink (called plastisol) is poured at one end of the screen. A squeegee is drawn across the screen under pressure, pushing the ink through the open areas of the mesh and onto the fabric below.

After printing, the ink is passed under a heat curer (usually a conveyor dryer at around 160 degrees Celsius). The heat fuses the plastisol permanently into the fabric fibres.

A five-colour design requires five screens, five ink mixing steps, five pass-throughs on the press and five separate cure runs.

Pros

  • Vivid, opaque colour. Plastisol ink sits on top of the fabric with high opacity. White on black is sharp and solid.
  • Durable. Correctly cured screen print ink lasts 100 plus wash cycles.
  • Low unit cost at volume. Once screens are made, printing speed is fast. At 100 plus units the unit price drops below most other methods.
  • Consistent. Every unit in the run looks identical. Digital methods have minor colour variation.

Cons

  • Setup cost per colour. Each screen costs money to produce. A one-colour job at 10 units may cost less than 5 units with a five-colour job.
  • Minimum order quantity. Setup cost per colour makes very small orders uneconomical.
  • No photographic gradients. Fine gradients and photographs do not reproduce well through a mesh. Halftone dots can simulate gradient effects, but it is a skilled process.
  • Colour change cost. Each colour requires a separate ink mix. Pantone matching for brand colours adds cost.
