We’ll discuss techniques, materials, and tips for achieving professional results that stand the test of time.
Understanding Custom Silk Screen Printing on Shirts:
The process of printing using a mesh stencil (screen) to transfer ink onto a substrate (often fabric) is called silk screen printing, serigraphy, or silkscreening. To achieve accurate colour arrangement and vivid printing, a separate screen is needed for each colour in the design. Silk screen printing on shirts is widely favored for its durability, versatility, and ability to create intricate designs with opaque colors.
The Process of Custom Silk Screen Printing on Shirts:
Design Selection and Preparation:
- Design Creation: The silk screen printing process begins with selecting or creating a design suitable for printing on shirts. Designs can range from simple logos and text to intricate illustrations and graphics. Making or altering designs to fit individual needs is a common application of digital design tools.
- Color Separation: For multi-color designs, each color in the design is separated into individual layers using design software. This creates separate screens for each color in the final print.
Screen Preparation:
- Screen Coating: Screens are coated with a light-sensitive emulsion, which is then exposed to UV light through a film positive of the design. This process creates a stencil (or “screen”) of the design on the screen.
- Screen Exposure: The screen is exposed to UV light, causing the emulsion to harden and create a stencil of the design on the screen. If you wipe away the parts of the screen that the film positive washed away, you’ll be left with the design stencil on the other side.
Shirt Preparation:
- Before printing, the shirts must be prepared by ensuring they are clean, flat, and properly aligned on the printing platen. Any wrinkles or imperfections can affect the quality of the print.
Ink Preparation:
- Ink Mixing: The design’s colour parameters dictate how the ink is blended. To make sure the colours come out right, people commonly utilise Pantone colour matching programmes.
- Ink Application: Ink is applied to the screen using a squeegee, which is then pulled across the screen to transfer the ink through the stencil onto the shirt. Each color in the design requires a separate screen and printing pass.
Printing Process:
- Silk Screen Printing: Once the screens are prepared and the shirts are aligned, the printing process begins. Each color in the design is printed sequentially, with the shirt passing under each screen for ink application.
- Ink Curing: After printing, the shirts are cured using heat to ensure the ink bonds with the fabric and becomes durable. This is typically done using a conveyor dryer or heat press machine.
Quality Control:
- Inspection: Each printed shirt undergoes thorough inspection to check for defects, irregularities, and print quality issues. Any misprints or imperfections are identified and corrected before final inspection.
Finishing Touches:
- Folding and Packaging: Once quality control is complete, the printed shirts are folded, labeled, and packaged according to customer specifications. Additional finishing touches, such as tagging or bagging, may be added for retail-ready presentation.
Advantages of Custom Silk Screen Printing on Shirts:
- Vibrant Colors: Silk screen printing offers vibrant, opaque prints with excellent color saturation and clarity.
- Durability: Silk screen printed designs are durable and long-lasting, able to withstand repeated washings and wear.
- Versatility: Silk screen printing can be applied to various fabric types, including cotton, polyester, blends, and even dark-colored garments.
- Cost-Effectiveness: Silk screen printing is cost-effective for bulk orders, with lower per-unit costs for higher quantities.
