BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a printing press and a printing method, and more particularly, to a printing press and a printing method with high dimensional accuracy, which can be applied to image formation required for the manufacture of electrical parts and the like.

The offset printing technique and the printing machine which are currently widely used are the blanket main body 33 which adhered the blanket 32 to the printing plate 31 to which ink K was apply | coated as shown in FIG. Is pressed to rotate, the ink K of the pixel portion is transferred to the blanket 32, and the blanket body 33 is pressed to the surface of the printed object 34 to rotate and the ink K of the pixel portion of the blanket 32 is rotated. Is transferred onto the printed object 34 to form an image on the printed object 34.

In this printing mechanism, as shown in FIG. 17, the blanket main body 33 and the flat printing plate 31 or the printed object 34 form a few millimeter band-shaped contact surface called a nip, and this nip Transfer of ink K is performed. And an image is formed on the to-be-printed object 34 as a collection of images transferred to this band-shaped nip.

At this time, the shake at the time of movement of the blanket main body 34 generates the position shake of the nip, resulting in distorting the finally transferred image G as shown in FIG. At this time, as the printing plate 31 becomes large, the blanket main body 33 becomes heavy and large, so that the distortion of the image G due to the shaking of the blanket main body 33 becomes remarkable, and when the large printing machine of high dimensional accuracy is produced, It is an obstacle.

In the present invention, the ink is not only a liquid containing a pigment or a dye for coloring, but also a functional resin such as a resin or a paste, such as a resin which is transferred to a predetermined shape using a printing technique. Include.

In addition, there is a pad printing (Fig. 19) as a printing method that does not use the blanket body in the offset printing method. The pad printing is a printing method in which the ink K is transferred to the printed object 34 using a rubber pad 35. Even if the printed object 34 has irregularities, printing is possible. There is a limit to making it bigger. In addition, since the pad 35 is generally spherical, the dimensional accuracy of an image that can be formed on the printed object 34 is remarkably poor. In addition, the outer circumferential portion of the pad 35, which is a root spherical body, is inclined with respect to the printing plate 31 and the printed object 34, is brought into contact with the printed object 34, and deformed so as to be in close contact with the printed object by pressing. Therefore, distortion or blurring tends to occur in the image of the outer peripheral portion. Therefore, as illustrated in FIG. 20, when the image G formed of dots aligned at the same pitch formed on the printing plate 31 is transferred to the printed object 34 by pad printing, as shown in FIG. The image with blurry dots is transferred.
