  • Patent number: 6923853
    Abstract: A meltable ink which is solid at room temperature, which ink is suitable for use in an indirect printing process, in which printing process the ink is transferred, by the use of an inkjet printhead, to a transfer element, whereafter the ink is transferred to a receiving material under pressure from the transfer element, the ink having a composition such that it is pressure-transferable at a temperature between a bottom temperature limit and a top temperature limit, wherein the ink has a deformation energy of less than 20×105 Pa.s at a temperature equal to said top temperature limit.
    Type: Grant
    Filed: July 3, 2003
    Date of Patent: August 2, 2005
    Assignee: Oce Technologies, B.V.
    Inventors: Martinus Antonius Kremers, Maurice Hendrikus Hubertinus Thijssen, Berby Marga Gerarda Weitenauer
  • Patent number: 6905203
    Abstract: A method of printing a receiving material with hot melt ink using an intermediate element having a surface containing an elastomer with a surface tension in which the polar part thereof is less than or equal to 20 mN/m, wherein the receiving material is brought into contact with the intermediate element in such manner that the ink transfers from the intermediate element to the receiving material, and wherein the elastomer has a hardness of less than 80 Shore A, a thermal conductivity coefficient greater than 0.15 W/mK, and in absorption of less than 10%, and a tan? of less than 0.3.
    Type: Grant
