When selecting t-shirts for custom printing, several quality criteria should be considered to ensure that the final product is durable, comfortable, and visually appealing. Here are the key factors:

1. Fabric Type

• Cotton: Soft, breathable, and comfortable; the most popular choice for custom prints. Look for high-quality cotton like combed cotton or ring-spun cotton for a smoother texture and longer durability.

• Polyester: More durable and moisture-wicking; commonly used for performance or sportswear. It holds color well but may feel less soft than cotton.

• Cotton-Polyester Blends: Combines the best of both worlds with a soft feel and enhanced durability. Popular for everyday wear.

• Tri-blend: A mix of cotton, polyester, and rayon for a super-soft feel and vintage look. It offers a more fitted style but may be less durable over time.

2. Fabric Weight

• Lightweight: Around 4-5 oz per square yard. Great for warmer climates or layering.

• Midweight: 5-6 oz. A versatile option that works for most people and climates.

• Heavyweight: Over 6 oz. Provides a more premium feel and is excellent for colder weather or high-quality prints.

3. Fit and Cut

• Standard Fit: Traditional and relaxed fit, typically worn by most people.

• Slim Fit: More modern, with a tighter cut around the body.

• Unisex: Available in a style that suits all genders.

• V-Neck, Crew Neck, or Scoop Neck: Depending on customer preference for neckline style.

4. Color

• Solid Colors: Easier to print on and generally more versatile.

• Heathered/Patterned Colors: These offer a unique texture and style but can be harder to print on due to the blended nature of the fabric.

• Dyeing Quality: Ensure the color is consistent, does not fade quickly, and does not affect the print quality.

5. Print Surface

• Smoothness: A smooth, flat surface ensures high-quality prints. Textured or uneven surfaces can cause distortion in the design.

• Pre-treatment: Some fabrics may require pre-treatment before printing to enhance print adhesion and longevity.

6. Durability

• Stitching and Seams: Strong, even stitching ensures the t-shirt won’t fall apart after a few wears. Reinforced seams at stress points (like the shoulders and sides) are a plus.

• Print Durability: Make sure the fabric holds the print well without fading or cracking over time. Choose t-shirts that work well with your printing method, whether screen printing, heat transfer, or direct-to-garment (DTG).

7. Shrinkage

• High-quality t-shirts should be pre-shrunk to prevent size changes after washing. If the shirt isn’t pre-shrunk, make sure it’s noted for accurate sizing information.

8. Eco-friendliness

• Organic Cotton: Grown without harmful chemicals, great for sustainable and eco-conscious customers.

• Recycled Materials: Some brands offer shirts made from recycled fabrics like plastic bottles or other waste materials.

9. Brand Reputation

• Choose brands known for their consistency and high-quality products, such as Gildan, Bella+Canvas, American Apparel, or Next Level Apparel.

By considering these quality criteria, you can ensure that your custom-printed t-shirts are comfortable, durable, and present your design in the best light.
