The present invention provides apparatus, systems and methods in which a pulse heater is used to apply dyes to a receiver in a rotary heating processing equipment. The pulse heater is first applied to a belt and is then removed from the belt, creating a dissipating heat. A sandwiched receiver comprising of two dyed donor papers is then subjected to the dissipating heat off the belt and also subjected to a constant heat generated from a drum to cause a phase change of the dyes within the donor papers to phase change from a solid to a gas, so the receiver can absorb and capture the phase changed dyes for a more saturated and brilliant finish.

L'invention fournit un appareil, des systèmes et des procédés qui utilisent un dispositif de chauffage pulsé pour appliquer des colorants sur un récepteur dans un équipement de traitement chauffant rotatif. Le dispositif de chauffage pulsé est tout d'abord appliqué à une courroie puis retiré de la courroie, créant une chaleur de dissipation. Un dispositif de réception enserré comprenant deux papiers donneurs colorés est ensuite soumis à la chaleur se dissipant à partir de la courroie puis soumis à une chaleur constante produite par un tambour pour provoquer un changement de phase des colorants des papiers donneurs et passer d'une phase solide à une phase gazeuse, de sorte que le dispositif de réception peut absorber et capturer les colorants ayant changé de phase et fournir un fini plus saturé et plus brillant.
