467824 ----------V. Description of the invention (6) Samples are followed by the heating device 6 and a hot melt applicator 7 is set. When the device is operated in the following gravure printing mode, the heating device 6 Treatment ^ 'The heat-applicable applicator 7 is used to produce a thin film on the steel plate 16 and then stick it. A gravure printing apparatus 25 or a embossing printing apparatus 26 is provided on the downstream side of the dazzling applicator 7 on the steel plate moving line. These printing devices 25 and 26 can replace the entire roller head on the vertical side. This printing device 2 5 and 2 6 are provided with a lower roller 2 1 that is shared by a roller head for gravure printing and a roller head for letterpress printing. The plate cylinder 1 is located on a roller head for gravure printing through a steel plate 1 6 7 Lower side and lower side of the roller head for letterpress printing. The state shown in the figure shows the case of printing in & stencil printing mode. However, in the case of gravure printing, the roller 21 is left intact, and the entire line of the relief printing roller head is replaced by the gravure printing Wheel head. On the downstream side of the printing device is the final heating device 9 ^ Photogravure printing device 25 From the ink storage 18 via the pickup roller 19 to attach ink to the plate cylinder roller 17 'Press the plate cylinder roller 17 to pass through the plate The steel plate 16 between the cylindrical roller 17 and the lower roller 21 transfers the pattern on the surface of the plate cylindrical roller 17 to the steel plate 16. In this case, a thin film is produced and adhered on the steel plate 16 by the hot-melt applicator 7, and the pattern engraved on the plate cylinder roller 17 is transferred to the thin film surface of the steel plate 16. In addition, the engraved printing device 26 was transferred from the ink storage section 18 to the engraved pattern cylinder roller Π with the pick-up roller 19 attached to the ink for one time. It is crimped to the lower roller 21 via the steel plate 16, and the pattern of the convex printing roller 20 is transferred to the upper surface of the steel plate 16. In the case of the convex printing, the above-mentioned film sticking operation using the hot melt applicator 7 is stopped.

Page 10 467 824 V. Description of the invention (7) Here 'if comparing gravure printing and convex printing, printing on convex plate' is transferred from the plate cylinder roller to the roller for letterpress printing and pressed on the steel plate The 'print' lacks sharpness anyway. However, when the plate cylinder roller is directly crimped to the steel plate like gravure printing, the engraved expensive plate cylinder roller will be worn or the pattern will be locally deformed. However, in this embodiment, since a hot melt applicator 7 is used to generate a thin film on the steel plate 16 and photographic CJ printing is performed thereon, the plate cylinder roller 7 is prevented from abrasion or deformation. As a result, convex plate printing is used for steel plates and the like for building materials that require less sharpness on the printed surface, and gravure printing is used for steel plates that require creativity or sharpness for the printing surface such as installation. In the present invention, the gravure printing and the convex printing can be switched by the same coating equipment. Fig. 7 is a schematic diagram for explaining the switching operation of the rotogravure gravure and roller head units of the & plate printing apparatuses 25 and 26 of the plate coating equipment according to the embodiment of the present invention. The gravure printing apparatus 25 and the embossed printing apparatus 26 of this embodiment are structurally different from the roller head on the upper side of the steel plate 16. The plate cylinder roller 17, the ink storage 18, and the pickup roller 19 (in the gravure printing post And the plate cylinder roller 17, ink storage 18, pick-up roller, and convex printing roller 20 (in the case of a convex printing device) are unitized, and the lower roller 21 is on the same steel plate moving line. The two printing devices 2 5 and 2 6 are shared. The roller head unit 27 for gravure printing and the roller head unit 28 for letterpress printing can be exchanged with each other. When the printing state of the gravure printing type is switched to the convex printing mode, the lower roller 21 is left intact, and the upper gravure is concaved. After the roller head unit 27 for plate printing is removed, it is replaced with the roller head unit 28 for letterpress printing. When switching from convex printing mode to gravure printing IH1

467824 V. Description of the invention (8) Similarly, only two roller head units 27 and 28 are exchanged. In the present invention, in the case where a series of identical steel plates are switched from the gravure printing to the convex printing without changing the moving path of the steel plates on the steel plate moving line (and vice versa), the steel plates may not be cut at the change. To continue the printing operation, as long as it is cut in the winding stage after the processing is completed, the printable portion of the steel plate is reduced. ^ The steel plate with the desired pattern was printed in this way. 6 The final heating device 9 was used for final drying, and then the film laminator was used. 3 The other film was laminated and pasted on the printing surface of the steel plate 6 and passed through the exit louver. I It is wound on a winder 丨 2 and taken out as a product. In this final stage, the thin film lamination process using the thin film laminator 3 may be omitted depending on the product in order to improve water resistance and the like. The switch between gravure printing and convex printing is not limited to the opening / replacement of the roller head unit as in the above embodiment, taking into account space or equipment costs, and other arbitrary devices such as a roller head with a mobile structure. Rewinding machine 丨 and winder 丨 2 series of rollers can be rolled up, rolled up, or rolled down, rolled down (that is, rolled out, rolled in). The effect of the invention is as described above. According to the present invention, since the gravure printing is performed on the thin surface after the steel sheet is directly generated and pasted, it is possible to process any desired pattern on the surface of the steel sheet. By laminating and adhering other films in order to protect the printed thin surface, the water resistance and corrosion resistance are increased, and a laminated steel plate that is inexpensive, rich in surface patterns, and widely used can be obtained. Using photogravure

Page 12 467824 V. Description of the invention (9) 'Case of plate printing mode' In the present invention, because a hot melt applicator is used to produce a film on a steel plate, gravure printing is performed on it to prevent plate cylinder rollers from abrasion or damage. The carved part of the roller surface is deformed. Moreover, it is also possible to perform the convex printing on the coated steel sheet which has not been produced and pasted with the same equipment. In addition, according to the present invention, 'the gravure printing and the convex printing can be switched according to the use of the coated plate in one device, and the device can produce coated products printed by the gravure and the printing products printed by the convex plate. Painting products can save space and equipment costs. In particular, in the case of gravure printing, since a hard steel plate is also directly produced and adhered with a film on the steel plate, photogravure printing is performed on the film surface, which can be used on the surface of the steel plate without damaging the cylinder roller head. Printing any desired pattern, and laminating and pasting other films in order to protect the printed film surface, the water resistance and corrosion resistance are increased, and it is possible to obtain cheap laminated steel plates with rich surface patterns.
