Variable data lithography apparatus and method
Patent Name Variable Data Lithography Printing Equipment and Methods Patent Applicant Gary Teng Ganghui Principal Applicant Address Massachusetts Inventor Gary Teng Ganghui Application (Patent) No. 03805880.4 Date of Application 2003.05.28 Certification Date Approval Notice Number 1642738 Validation Notice Date 2005.07 .20 Specification CD-ROM D0529 Main classification number B41C1/10 Classification number B41C1/10 Division Original application number Priority item 2002.6.4 US 10/162,345 Abstract A variable-data lithographic printing apparatus comprising sensitization around a printing cylinder Layer coating apparatus, exposure source, developing apparatus (optionally), inking apparatus, transfer system (optionally), and cleaning apparatus (optionally). During the printing operation, each surface area of ​​the rotating drum is continuously subjected to cycles of coating, imagewise exposure, development (optionally), inking, printing of inks onto the receiving media, and (optionally) printing. If a photosensitive layer developed using ink and/or fountain solution is used, the developing device can be omitted. In an alternative design, the drum may be replaced with a continuous supply of ribbon with a lithographic substrate surface. In another alternative design, the drum and coating device may be replaced by a continuous supply of pre-sensitized ribbon containing a photosensitive layer on the substrate. Slavs 1, a variable data lithographic printing apparatus comprising: (a) a printing cylinder; (b) a coating device for depositing a photosensitive layer on the surface of the cylinder, wherein the photosensitive layer is exposed to actinic light The radiation is able to harden, and the affinity or the estrangement developed by the photosensitive layer for the at least one printing liquid is essentially the opposite of the affinity or the alienation that the surface of the cylinder is exposed to the printing liquid. The at least one printing liquid is selected from the group consisting of an ink and a blocking fluid used as an ink, and (c) an exposure apparatus for exposing the photosensitive layer on the surface of the drum with actinic radiation according to digital imaging information. Thereby forming a hardened zone in the exposed area, forming a non-hardened zone in the non-exposed area; and (d) an inking device for applying ink or fountain solution and ink to the surface of the drum; (e) wherein The devices (b) to (d) are mounted near the surface of the drum, and are arranged in order along the drum surface in the drum rotation direction; each one-way during the printing operation, each device (b) to (d) is printed on the design Within the width, passed by the device Complete design features on the surface region of the drum.
