Abstract
Systems and methods are provided for thermal sublimation imaging and more generally thermal pressing through a continuous or intermittent feed-through thermal pressing system. Cutting assemblies may be configured to cut, connect, advance, and/or align transfer media. The transfer media may have images created using inks, dyes, or the like that are configured to be sublimated into a substrate material within a sublimation assembly. The substrate may be interposed between upper and lower transfer media to allow for dual-side imaging via thermal sublimation. A thermal sublimation chamber may include a pre-confinement zone to reduce ghosting, a preheat zone, a thermal saturation zone to effectuate sublimation and image transfer, and/or a post-sublimation cooling zone to reduce ghosting. A post-sublimation collection system may separate transfer media from substrate(s).
