Both methods are great. Dye sublimation and custom screen printing are both durable and long-lasting. However, which method is better for you depends on some factors like your requirements and budget. For example, dye sublimation is better for smaller projects. It is preferable to use polyester material and is quite beneficial when you need several colors in a print. On the other hand, screen printing is better for larger projects. It is cost-effective. Many ink types can be used to give vibrant effects. Screen printing is suitable for many fabrics other than cotton.
