Sublimation printing involves using heat to transfer dye onto fabric like polyester. It provides brighter colors and smoother transitions than inkjet printing, with the dye becoming permanently embedded in the fabric. However, sublimation printing is slower than inkjet due to the two-step heat transfer process, making labor costs higher. It can also be prone to creasing or wrinkling the fabric during printing, ruining the print. Newer printer designs that feed fabric and paper together are helping to address these issues.
