A heat press machine is a piece of equipment used to apply vinyl, screen printed transfers, and other types of transfers to apparel. A heat press works by using a set time, temperature, and pressure to apply the transfers. First, we take a blank shirt and place a transfer down onto the shirt. Then, we close the heat press and it is transferred onto the shirt with heat and pressure. This allows the vinyl to actually melt a little into the fabric of the shirt. In comparison to screen-printing, apparel that is heat pressed will typically appear sharper and more vibrant, but does not hold up quite as long as a well-cured screen print. Credit
