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

Abstract
To provide a manufacturing apparatus of a coated steel sheet using ink jet printing and a manufacturing method thereof. A manufacturing apparatus of a coated steel sheet includes: a tension controller which adjusts the tension of a steel sheet; a meander controller which adjusts the meanders of the steel sheet; speed controllers which adjust the speed of the steel sheet; and a printer which performs printing using ink jet printing on the steel sheet surface adjusted within a range where the tension is determined and a range where the degree of meanders is determined by the tension controller and the meander controller.
Description
technical field [0001] The present invention relates to a manufacturing device and a manufacturing method of a coated steel plate, and more specifically, to a manufacturing device and a manufacturing method 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 roll printer (Roll Printer) and printing steel plate using pattern transfer paper. For screen printing stencils, a batch type process utilizes printing on sheets rather than coils, and roll printing stencils utilizes ink or paint applied to rollers etched with printed patterns. The method of coating on the surface, the method of transferring the transfer paper with the printed pattern to the steel plate for printing on the steel plate with transfer paper. [0003] However, the above-mentioned prior art has the following disadvantages. [0004] Although the screen...
