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°.
