Coated steel sheet manufacturing apparatus using inkjet printing

Abstract

A coated steel sheet manufacturing apparatus using inkjet printing is disclosed. The coated steel sheet manufacturing apparatus, according to one embodiment of the present invention, comprises a printing device for printing on a surface of a steel sheet by using inkjet printing, wherein the printing device comprises: a plurality of ink heads arranged in the progressing direction of the steel sheetat a printing area; and a plurality of curing devices arranged at the rear of each ink head (the progressing direction of the steel sheet) so as to cure ink droplets dropped on the steel sheet.

Description

technical field [0001] The present invention relates to a manufacturing device of a coated steel plate, and more specifically, to a manufacturing device of a coated steel plate using inkjet printing. Background technique [0002] The steel plate with pattern printed on the surface can be divided into printing steel plate using screen, printing steel plate using roller printing and printing steel plate using pattern transfer paper. For screen printing stencils, a batch type process utilizes a printing process on sheets rather than coils, and roll printing stencils is performed by dipping ink or paint onto a roller etched with a printing pattern. The method of coating, the method of transferring the transfer paper printed with the pattern to the steel plate for printing on the steel plate by transfer paper. [0003] However, the above-mentioned prior art has the following disadvantages. [0004] Although the screen printing method has a relatively simple production process, ...

Problems solved by technology

[0004] Although the screen printing method has a relatively simple production process, it is necessary to separately make a screen as a printing plate according to the pattern to be printed or the type of product, and the number of screens increases depending on the number or type of colors, resulting in a labor-intensive process. slow and unproductive

[0005] The roll printing method is different from the screen printing method. It is a continuous roll coating method, so it is highly productive. However, the printing pattern is simple and it is difficult to express various patterns, so it is difficult to achieve a variety of product designs.

Also, like the screen printing method, the number of printing cylinders increases depending on the number of colors, and the production process is complicated, resulting in a decrease in production efficiency
