A transferring layer on a transfer cylinder improves separability for facilitating complete transfer of ink from the transferring layer onto the material to be printed. This separability arises from the inclusion of a fluorine compound or a silicone compound in the transferring layer. In order to prevent incomplete transfer of ink from an intaglio printing plate to this transferring layer of the transfer cylinder, the printing speed of the transfer cylinder relative to the plate is controlled, and at the same time the viscosity of the ink is kept in a certain range. The use of a screen mesh is eliminated, thus preventing various problems associated with its use. A fine pattern of thick film can thus be printed with accuracy on various materials including fragile materials and those with surface irregularities. |
