  • Printing process
    Patent number: 8235517
    Abstract: The invention relates to an ink jet printing process which comprises the steps of i) applying a radiation-curable primer to a substrate to form a layer of primer, ii) ink jet printing a radiation-curable ink onto the primer layer, and iii) curing the primer and the ink, wherein the viscosity of the primer increases rapidly after application to the substrate.
    Type: Grant

  • Ink-jet printing process and ink
    Patent number: 8002884
    Abstract: The invention relates to a process of ink jet printing a radiation-curable ink from a printer having a de-wetting faceplate onto a substrate in which the ink is such that it has an advancing contact angle on the substrate of no more than 22° and a receding contact angle on the faceplate, after a period of contact of one month, of greater than 28° . The invention also provides a radiation-curable ink for use in an ink jet printer having a de-wetting faceplate, the ink having a receding contact angle on a material having a surface energy in the range of 16 to 20 dyne/cm of greater than 28° after a period of contact of one month and having an advancing contact angle on a substrate having a surface energy of less than 30 dyne/cm of no more than 22°.
