Screen Printing: For Boldness & Bulk
The Workhorse of Customization
Screen printing involves creating a stencil (or "screen") and pushing ink through it onto the cotton fabric. Each color in your design requires a separate screen, making it ideal for designs with a limited number of solid colors.
- Best For: Simple logos, text, and bold graphics with 1-4 solid colors.
- Key Advantage: Extremely cost-effective for large quantity orders (1,000+ pieces).
- The Result: A thick, vibrant, and highly durable print that sits on top of the fabric.
DTG Printing: For Detail & Full Color
The Artist's Choice
Direct-to-Garment (DTG) printing works like a standard inkjet printer, applying water-based inks directly onto the cotton. This allows for an unlimited number of colors and incredible detail, as the ink is absorbed by the fabric fibers.
- Best For: Photorealistic images, complex illustrations, gradients, and intricate, multi-color designs.
- Key Advantage: No setup fees per color, making it great for smaller runs with complex art.
- The Result: A soft, breathable print that is integrated into the fabric, with no raised texture.
Heat Transfer: For Versatility & Vibrancy
The Versatile Solution
This method involves printing your design onto a special transfer paper, which is then applied to the cotton bag using heat and pressure. It's a highly versatile technique that combines the vibrancy of DTG with some of the durability of screen printing.
- Best For: Designs that need to be exceptionally vibrant, especially on dark-colored bags.
- Key Advantage: Excellent color saturation and the ability to reproduce fine details consistently across a large batch.
- The Result: A smooth, slightly glossy finish that sits on top of the fabric.
