  • Patent number: 9321255
    Abstract: A printing method wherein when pressing a printing blanket made from an elastic material which becomes thinner towards the tip thereof, is pressed against an original plate for printing, to which ink has been applied, the descending speed is set to a minimum when the tip of the printing blanket comes into contact with the original plate for printing, and as the pressing progresses, the descending speed is increased. Similarly, when the printing blanket is pressed against the surface to be printed, the descending speed is set to a minimum when the tip of the printing bracket comes into contact with the surface to be printed and as the pressing progresses, the descending speed is increased.

  • Publication number: 20140333484
    Abstract: This antenna (10) has an underlying print layer (2) which is upon the surface of a material (1) to be printed in a predetermined antenna pattern, and an electro-less plating layer (3) applied to the surface of the underlying print layer (2). The underlying print layer (2) is formed from an ink (2a) and a metallic powder (2b).

  • Publication number: 20130042772
    Abstract: To provide a printing blanket that enables good and rapid printing on a nonlinear printing surface (e.g., a doughnut-shaped outer surface). A printing blanket 10 is ring-shaped in plan view and includes an attachment surface 1, an inward facing surface 2, an outward facing surface 3, the inward and outward facing surfaces 2 and 3 being protruding surfaces, and ridge lines 4 which smoothly connect the inward facing surface 2 and the outward facing surface and which are substantially arc-shaped in section. A circle connecting the ridge lines 4 serves as a pitch circle 5 having a curvature radius P5. The printing blanket is suitable for printing on a steering wheel 20 having a pitch circle 8 having a curvature radius P8 which substantially coincides with the curvature radius P5.
