  • Method and device for manufacturing pellets of hot-melt ink
    Patent number: 7252280
    Abstract: A method for manufacturing pellets of hot-melt ink which includes the steps of filling molten ink into a mold cavity defined by a first die and a second die of a mold, allowing the ink to cool down and solidify in the mold cavity, and heating at least one of the first and second dies for re-melting the surface of the ink pellet to facilitate its removal from the mold cavity.
    Type: Grant
    Filed: August 20, 2003
    Date of Patent: August 7, 2007
    Assignee: OCE-Technologies B.V.

  • Ink composition for a meltable ink and a method of printing a substrate with such an ink composition
    Patent number: 6471758
    Abstract: An ink composition for a meltable ink usable in a printing device in which ink drops are ejected from ink ducts, which comprises agents which reversibly cross-link the ink, the said agents containing a gelling agent. When an ink drop which has been transferred to a substrate passes over into a gel during the cooling process, the consequence is that the viscosity of the melted ink drop increases greatly so that the drops become relatively immobile. In this way the ink drops are prevented from uncontrollably flowing into the paper. As a result, inks of this kind are suitable for use on both porous and smooth substrates. In addition, these inks have been found suitable for use in a printing device in which printed substrates are subjected to thermal after-treatment.
