Description

A device for manufacturing a pattern layer having a gradient effect and a method for manufacturing a pattern layer having a gradient effect{PATTERN LAYER MANUFACTURING DEVICE WITH GRADAITION EFFECT AND PATTERN LAYER MANUFACTURING METHOD WITH GRADAITION EFFECT}

The present invention relates to an apparatus for manufacturing a pattern layer having a gradation effect and a method for manufacturing a pattern layer having a gradation effect, and more specifically, by printing ink having different densities directly on a pattern portion, the color layer and the pattern layer are one without distinction. It relates to an apparatus and method for providing a pattern layer that has a gradient effect in the process and can suppress the formation of halftone dots.

The substrate having the conventional gradation effect and pattern is formed in various patterns such as circular, radial, and diagonal lines, and can be formed to have a gradient color at the same time, thereby giving the user a mysterious and luxurious aesthetic. Substrates having such a gradient effect and pattern are widely used from interiors such as desks, chairs, and walls to accessories such as cell phone cases.

The substrate having the conventional gradation effect and pattern has a problem of process hassle because the pattern layer formed with a pattern such as a gradient ink printing layer and an emboss is separately formed, as in Korean Patent Registration No. 10-0821995. There was a problem.

In addition, in the process of printing to have a gradation effect through the DDP (DOT TO DOT PRINT) technique, there is a problem in that dots are formed by empty spaces between dots and dots in a portion where the density of dots (DOT) is low.

In addition, an imprinting method is mainly used to manufacture a pattern layer. According to a conventional imprinting process, a resin is applied on a substrate and a mold having a pattern is pressed onto the applied resin. The resin is cured while the soft mold is pressed, and when the curing of the resin is completed, the soft mold is removed to form a pattern on the resin. Such conventional prior arts include Korean Patent Registration No. 10-1847100 and Korean Patent Registration No. 10-1219040.

However, according to the conventional imprinting process, after applying the resin on the upper surface of the substrate, there is a problem in that bubbles are generated in the resin in the process of imprinting on the resin to form a pattern. When a pattern is formed in a state in which bubbles are generated in the resin, the degree of pattern breakage increases or the pattern is not formed in a desired shape, and various problems in which the bubbles are visible are generated.

Therefore, in order to solve the above problems, in the present invention, a resin is supplied to a surface of a soft mold on which a pattern is formed through a dot (DOT) printer so that the density is different, and the soft mold supplied with the resin is pressed against a substrate to harden it. I would like to suggest.

Hereinafter, with reference to FIGS. 10 to 13 will be described in detail with respect to the process and method of removing the dot 122, one of the features of the present invention.

The ink 120 initially printed on the pattern part 111 has a predetermined reference height or diameter intended in advance by an operator, thereby forming an empty space M between the inks or when light ink is used. It is possible to remove or reduce the half-dots 122 caused by the thin thickness of. However, the ink 120 is printed by the dot printer 300. At this time, there is a problem in that the ink 120 does not have a predetermined reference height or a predetermined reference diameter, and thus a dot 122 is generated. In order to solve this, the present invention is characterized in that, by pressing the ink 120 applied by the dot printer 300, the height or diameter of the ink is deformed to remove or reduce the dot 122. In detail, the ink 120 applied by the dot printer 300 has an initial first height H1 and a first diameter D1. Here, by pressing the ink 120 through the pressing roller 230 or the substrate S, etc., the height is lowered, and the diameter is largely deformed to remove or reduce the dot 122.

On the other hand, when the ink 120 is pressed to remove or reduce the half-dots 122, when the ink 120 sequentially changes the print density in accordance with the progress direction to give a gradient effect, the density of the ink 120 It becomes different. That is, the overlapping thicknesses between the inks 120 are different in thickness in one direction and the other. In this case, the pressing roller 230 and the substrate S or other pressing configurations may be configured such that the ink 120 is superimposed to press different thicknesses at each location corresponding to different thicknesses. 13 is a view showing that the ink 120 is pressurized to show a gradation effect so that the dot 122 is removed or reduced.

This is a process of applying ink to the soft mold 110 through the dot printer 300, but printing to give a gradation effect by varying the application density of the applied ink.

The step of pressing the soft mold 110 so that the printed ink 120 contacts the upper surface of the substrate S is printed on the soft mold 110 by pressing the soft mold 110 to contact the upper surface of the substrate S This is a process of pressing and fixing the ink 120.

Further, the printed ink 120 is applied to have a first height H1 and a first diameter D1.
