Abstract

The invention discloses an endless printing device for a metal plate and a printing method. The printing device comprises a transfer roll (20), a scraper (30), an engraving printing roll (40), and a supporting roller (50). The transfer roll rotates at a speed identical to the linear velocity of a printed article (1). A forming groove (21) in which intaglio printing patterns are formed on the surface is formed so that ink or paint is supplied to the forming groove. The scraper removes the paint remained on the surface of the transfer roll except for the forming groove. Emboss units (41) which are in a line-contact with the transfer roll are formed intermittently on the engraving type printing roll in a circumferential direction, and intaglio units (42) of a predetermined depth are formed between the emboss units. The paint inside the forming groove is transferred on the emboss units so that the printed article is printed. The supporting roller is installed to face the engraving printing roll while the printed article (1) is arranged between the supporting roll and the engraving printing roll, thereby supporting the printed article (1).

Description

technical field [0001] The present invention relates to a continuous printing device and printing method for metal plates. [0002] In particular, it relates to improving the structure of the printing rubber roller to prevent ink (or paint) from transferring to the non-transfer surface of the printing rubber roller, thereby improving the printing quality and significantly reducing the amount of ink (or paint) and detergent used A continuous printing device and printing method for a metal plate. Background technique [0003] Metal sheets, represented by steel sheets, coated steel sheets or aluminum sheets, and aluminum alloy sheets, have both advantages of high strength and easy processing. Therefore, after various processing, they are widely used in household appliances, automotive parts, building materials, etc. . [0004] Surface treatment is carried out in order to prevent corrosion of such sheet metal processed products and to obtain a good appearance. [0005] surfac...
