Embodiment 1

[0042]In this embodiment, the printing process is as follows, a gravure roll 1, the gravure roll 1 is immersed in the printing ink storage tank 6 to continuously coat the ink, the gravure roll 1 after the ink is dipped Use the scraper 2 to scrape off excess ink, and the ink pattern on the gravure roller 1 is transferred to the surface of the printing rubber roller 3, and the printing rubber roller 3 prints the ink pattern on its surface on the steel plate 7, and the other side of the steel plate is provided with a Support roller 4.

Embodiment 2

[0044] In this embodiment, the printing process is as follows, a gravure roll 1, the gravure roll 1 is immersed in the printing ink storage tank 6 to continuously coat the ink, the gravure roll 1 after the ink is dipped Use the scraper 2 to scrape off the excess ink, the ink pattern on the gravure roller 1 is transferred to the surface of the printing rubber roller 3, and the printing rubber roller 3 prints the ink pattern on its surface on the steel plate 7, and the support of the steel plate 7 is on the plane On the support transmission belt 5, on the other side of the printing rubber roller 3, a cleaning roller 9 is arranged, and the cleaning roller 9 is immersed in the washing tank 8 and is continuously cleaned. Another doctor blade 2 is arranged on the printing rubber roller 3 .

[0045] In the steel plate printing process of the present invention, if the ink printing lines are not clear, a cleaning roller can be added at the position of the printing rubber roller.

[0053] Through research, the direction of the researchers of the present invention, the preferred solvent ratio, adopts the ratio of common type solvent: slow-drying solvent=1:1.

[0054] Under the condition that described ink of the present invention has been proportioned, preferred printing conditions are as follows:

[0055] (1) Drying temperature: 180 degrees;

[0056] (2) SP value (surface tension) above 13;

[0057] (3) The continuous coating and printing process speed for steel coils can reach 15-40 m / min, and the printing process speed for single steel plates can reach 5-20 m / min.

Abstract

The present invention is printed metal plate with intaglio offset transfer printed patterns and its making process. On the surface of coated steel sheet, patterns are first printed with ink fitting the surface coating of steel sheet and through intaglio offset printing, and high temperature cured paint or UV cured paint is then roller coated to the surface of the patterns. The printed metal plate has high decorating effect. Compared with available technology, the present invention has the advantages of environment friendship and low cost.

Description

technical field [0001] The invention belongs to the field of color printed metal plates used for housings of household appliances, interior and exterior decoration of buildings, etc., and particularly relates to a steel plate suitable for various bending, impacting, stretching and other sheet metal processing after indirect printing with gravure rubber rollers and a manufacturing method thereof. Background technique [0002] At present, colored metal plates used in the market for housings of household appliances and interior and exterior decoration of buildings, such as refrigerator shells, refrigerator side panels, microwave oven shells, air conditioner shells, washing machine shells, etc., generally use colored pre-painted steel plates and colored laminated steel plates. [0003] The color pre-coated steel plate adopts the following structure: the base material is made of steel plates such as cold-rolled plate, electro-galvanized plate, hot-dip galvanized plate, galvanized ...
