1. Screen Printing: Screen printing is a popular method for custom T-shirt printing, especially for large orders. It involves creating a stencil (or screen) for each color in the design and then using a squeegee to push ink through the stencil onto the T-shirt. Screen printing is known for its durability and vibrant colors, making it suitable for simple designs with few colors.
2. Direct-to-Garment (DTG) Printing: DTG printing is a digital printing method that works similar to a traditional inkjet printer but on fabric. It's ideal for detailed designs, photographs, or designs with many colors, as it can achieve complex patterns and gradients. DTG printing is suitable for smaller orders or one-off prints.
3. Heat Transfer Printing: Heat transfer printing involves printing the design onto a special transfer paper using a printer and then transferring the design onto the T-shirt using heat and pressure from a heat press machine. This method is suitable for small orders or designs with multiple colors and intricate details. However, it may not be as durable as screen printing.
4. Vinyl Cutting and Heat Press: Vinyl cutting involves cutting designs out of colored vinyl sheets using a computer-controlled cutter. The cut vinyl is then heat-pressed onto the T-shirt. This method is commonly used for customizing sports jerseys or creating designs with solid colors and sharp lines.
5. Sublimation Printing: Sublimation printing involves transferring dye onto the T-shirt using heat and pressure. It works best on polyester fabrics and produces vibrant, all-over prints. Sublimation printing is suitable for designs that cover the entire T-shirt, such as photo prints or colorful patterns.
6. Embroidery: Embroidery involves stitching designs onto the T-shirt using specialized embroidery machines. This method is suitable for adding logos, monograms, or text to T-shirts and provides a textured and professional look. Embroidery is often used for customizing polo shirts or premium-quality garments.

When choosing a printing method for custom T-shirts, consider factors such as the complexity of the design, the desired quantity, the fabric of the T-shirts, and your budget. Additionally, work with a reputable printing service provider who can advise you on the best printing method for your specific needs and ensure high-quality results.
