What is Screen Printing?
The most durable and cost-effective printing method for bulk custom apparel, creating vibrant designs that last 50+ washes.
What is Screen Printing?
Screen printing is a printing technique that pushes ink through a mesh screen onto fabric using a rubber squeegee. The screen contains a stencil created through photographic exposure, allowing ink to transfer only in the design areas. Each color requires a separate screen, making it ideal for simple, bold designs with limited colors.
The process creates thick, vibrant ink deposits that penetrate deep into fabric fibers, resulting in designs that last 50-100+ washes without cracking or fading. This durability makes screen printing the preferred method for bulk custom apparel, team uniforms, and promotional merchandise.
Originally developed in ancient China and Japan, modern screen printing emerged in the early 20th century and revolutionized commercial textile printing. Today, it remains the most cost-effective method for orders of 50+ pieces, with costs dropping to $2-3 per shirt for bulk quantities.
How Screen Printing Works
Step 1: Screen Preparation
The process begins with selecting the appropriate mesh screen. Polyester mesh is most common, though nylon and stainless steel are used for specialized applications. Different mesh counts are chosen based on design complexity:
- 60-86 mesh: Thick inks, bold designs, athletic numbers
- 110-156 mesh: Standard text and logos
- 200-305 mesh: Fine details and thin inks
Step 2: Stencil Creation
The mesh is coated with photosensitive emulsion using a scoop coater. This light-reactive coating remains liquid until exposed to ultraviolet light in the 350-420 nanometer spectrum. A transparent film with the design is placed over the coated screen, and the assembly is exposed to UV light for 13-14 minutes.
The light hardens the emulsion in exposed areas while leaving design areas (covered by the film) in liquid form. Pressurized water then washes away the unhardened emulsion, creating clean openings that match the design shape.
Step 3: Ink Application
During printing, the screen is positioned over the garment with ink placed on top. A floodbar first fills the mesh openings with ink. The squeegee then moves downward, contacting the fabric while pushing toward the rear of the screen. This action uses capillary action to pump ink through the mesh openings onto the fabric in controlled amounts.
Step 4: Curing
The final step involves curing the ink to create a permanent bond. Plastisol ink cures at 320°F (160°C) for standard formulations or 270°F (132°C) for low-cure variants. Flash drying occurs at 180-220°F for 7-12 seconds between color layers. Proper temperature ensures the plasticizer evaporates and the ink forms a durable, flexible film.
Screen Printing Ink Types
| Ink Type | Cure Temperature | Durability | Best For |
|---|---|---|---|
| Plastisol | 320°F (160°C) | 50-100+ washes | Cotton, blends, bulk orders |
| Low-Cure Plastisol | 270°F (132°C) | 40-80 washes | Polyester, athletic wear |
| Water-Based | 300-320°F | 30-60 washes | Soft hand-feel, eco-friendly |
| Discharge | 320°F + Steam | 50+ washes | Dark garments, vintage look |
Plastisol: The Industry Standard
Plastisol remains the most popular screen printing ink because it doesn't dry in the screen, has excellent opacity, and creates vibrant colors on both light and dark fabrics. The thick consistency allows for precise application and consistent results across large print runs.
For popular cotton blanks like the Gildan 5000, plastisol provides optimal adhesion and durability. The ink chemically bonds with cotton fibers during the curing process, creating a permanent, wash-resistant design.
Screen Printing Advantages
Bulk Cost Efficiency
Costs drop to $2-3 per shirt for orders of 50+. Setup fees are amortized across the entire order, making large runs extremely economical.
Maximum Durability
Designs last 50-100+ washes without cracking, fading, or peeling. Superior to DTG and heat transfer for long-term use.
Vibrant Colors
Thick ink deposits create bold, opaque colors that pop on both light and dark fabrics. Excellent color matching capabilities.
High-Volume Production
Once set up, screens can print hundreds of garments per hour. T-Shirt Elephant's six-color presses handle up to 10,000 shirts daily.
Best Applications for Screen Printing
Screen printing excels in specific scenarios where its strengths align with project requirements:
- Team uniforms and jerseys: Durability essential for repeated washing and wear
- Employee apparel: Consistent branding across large organizations
- Event merchandise: Cost-effective for promotional giveaways
- Retail apparel: Professional finish for commercial sale
- School spirit wear: Bold designs with long-lasting appeal
Popular brands like Gildan and Comfort Colors are specifically designed to work well with screen printing inks, ensuring optimal results for custom apparel projects.
