  • Publication number: 20100212523
    Abstract: A printed item contact member 54 according to the present invention includes: a base material 50; a fixing layer 52 that is formed on the surface of the base material 50 and substantially spherical particles 51 are fixed thereto; and a remarkably thin low-surface-tension coating layer 53 that covers the surface of the fixing layer 52 having the substantially spherical particles 51 fixed thereto and that exhibits release properties with respect to a printed item. The printed item contact member exhibits high ink repellency while maintaining the micro-uneven surface structure and is free from adhesion of yarn waste or dust to the member during cleaning, and therefore can be suitably used as, for example, a member for printing device in contact with the surface of printing paper.

  • Publication number: 20100024670
    Abstract: An object is to provide a printing apparatus or the like that improves printing accuracy when a carriage moves back and forth for printing. A block 51 on a block surface plate is mounted on the block surface plate at a predetermined location. On the other hand, a substrate 54 on a print surface plate is mounted at a location corresponding to the location of the block 51, that is, a location where a picture transfer is desirably received from a blanket cylinder 13. In the present invention, the arrangement of sliders 52 and 40 for the block carriage 50 and a printing carriage 7 to reciprocate along two rails 30 in the block carriage 50 and that in the printing carriage 7 are the same. With such an arrangement, at the same location immediately below the blanket cylinder 13 on the same track 30, even when the straightness of the rail 30 is not sufficient, the block 51 and the glass substrate 54 take the same position at the location, and thus print misalignment can be prevented.
