Title:
PRINTING APPARATUS AND PRINTING METHOD
Document Type and Number:
Japanese Patent JP2011112871
Kind Code:
A
Abstract:

To provide an offset printing apparatus in which ink-repellent particles are adhered to a plate forming member to form a plate, and in which the ink-repellent particles are reused while preventing the ink-repellent particles from being deformed, damaged, or lost, thus preventing waste of the ink-repellent particles as the plate forming material, and reducing the printing cost.

A printing apparatus includes: the plate forming member 1 that forms a rewritable plate; a latent image forming means; a projection forming means 4 configured to selectively adhere the ink-repellent particles to the portion of a surface of the plate forming body where a latent image is formed in order to form a projection; a recording material supply means 5; an intermediate transfer member for transferring a recording material; a pressing means configured to press the recording material on a surface of the intermediate transfer member during the transfer of the recording material to a recording medium; and a conveying means for conveying the recording medium. The printing apparatus further includes: a particle storage means for storing the ink-repellent particles; and a particle washing means for washing at least some of removed ink-repellent particles. At least some of the ink-repellent particles removed from the plate forming member and washed are filled into the particle storage means.
