  • Patent number: 8057031
    Abstract: A method of creating an image on a recording medium including a support having thereon a porous fusible layer, using an ink composition that is solid at room temperature and liquid at elevated temperature including the steps of generating droplets of the ink composition with an ink jet print head, transferring the droplets of the ink composition to the surface of the fusible layer, thermally treating the recording medium such that the ink transferred to fusible layer passes into the medium away from the surface of the fusible layer while the fusible layer remains substantially unfused, and when the ink has passed into the medium, treating the recording medium to fuse the fusible layer to become a protective overcoat. The present invention also pertains to a system for creating an image on a recording medium.

  • Patent number: 7976940
    Abstract: Coatings which are applied to a component have to be removed again in a complex way in certain regions, since a coating was not desired to be present in those regions. The subsequent removal of this layer adversely affects the component, for example its geometry. The method according to the invention for coating a component includes a masking which at least partially comprises a ceramic powder and can therefore easily be removed after the component has been coated.
