The powder shaker is an essential component that enhances the heat transfer process. It works by evenly dispersing a fine powder, such as sublimation powder or flocking fibers, onto the printed design. The powder adheres to the ink on the fabric, enhancing the visual appeal and providing additional texture, depth, or special effects to the print. The powder shaker ensures a uniform distribution of the powder, preventing clumping or uneven application, resulting in consistent and professional-looking prints.
