Abstract
A thin film-forming apparatus includes: an anilox roll having a large number of ink cells, an ink supply device for charging ink into the ink cells of the anilox roll, a printing roll having a projection which contacts the anilox roll is transferred and transferring the ink in the ink cells of the anilox roll is transferred to the projection, and a printing table for holding a material to be printed and bringing the material into contact with the projection of the printing roll so as to transfer the ink on the projection of the printing roll to a surface of the material. A first driving device is provided for rotating the anilox roll, a second driving device is provided for rotating the printing roll independently of the anilox roll, and a control device is provided for controlling the first and second driving devices so that the difference in the rotational speeds between the anilox roll and the printing roll is within a predetermined range. The anilox roll and the printing roll are driven independently of each other by the control device so that the difference in the rotational speeds between the anilox roll and the printing roll is within a predetermined range. The apparatus is …
