Abstract:
An image is printed on a medium by means of an electrographic device using an ink composition comprising heat activated inks, without substantial activation of the inks during the process of printing the image onto the medium. A molecular sieve added to the ink composition assists activation control. The image is transferred from the medium to the object on which the image is to permanently appear by applying sufficient heat and pressure to the medium to activate and permanently transfer the inks from the medium to an object.
Abstract:
An image is printed on a medium by means of a computer-driven printer (6) using an ink composition comprising heat-activated dye solids, without activating the dye solids during the process of printing onto the medium. The image is transferred from the medium to the object (8) on which the image is to permanently appear by applying heat and pressure to the medium to activate the dye and transfer the image to the object (8). The liquid form of the ink composition uses a liquid carrier and an emulsifying enforcing agent which has an affinity for the dye. The emulsifying enforcing agent shields the heat-activated dye both prior to, and during, the printing process.
Abstract:
An image is permanently transferred to a substrate having a cotton component, or other component which is absorbent or porous, from a medium printed with the image by a computer driven printer. A polymer surface preparation material and an ink are transferred by the printer to the medium from a ribbon or ink composition containing the ink and the surface preparation material, without activating the surface preparation material. The image is transferred from the medium to the substrate by applying sufficient heat and pressure to the medium to transfer the ink and the surface preparation material, with the surface preparation material bonding the ink to the substrate.
