Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a cut foil material, a kind of material for obtaining cut foil by slitting it into narrow widths, particularly a roll or rotary screen on the front and back sides of the cut foil material. This invention relates to a method for manufacturing cut foil original fabric that exhibits a plane-symmetrical pattern by printing or stamping.

When applying a plane-symmetrical pattern to the front and back sides of the cut foil material using such printing or stamping methods, the front and back sides of the cut foil material are pasted together to create a pattern on the front and back sides of the cut foil material. Compared to the case with
Not only is productivity excellent, but alignment of front and back patterns is also easy.

For paper cut foil sheets with patterns on both the front and back sides, it is important that not only the designs on the front and back sides match, but also the colors and textures on the front and back sides match.

Generally, the reason why a cut foil material is made to have a two-sided pattern that is plane symmetrical on the front and back is that when the cut foil obtained by slitting it is woven into the fabric during weaving, the pattern element (the pattern element This is because even if the part (in which the pattern was initially subdivided) is turned over, the pattern element on the back side occupies the front side, making it a kind of reversible by cutting foil in the ability to express the pattern.
The patterns that appear on textiles are an accumulation of woven cut foil and adjacent pattern elements of cut foil. The greatest characteristic of the technique of creating patterns on textiles by weaving patterned cut foil is that the pattern originally appearing on the original cut foil is reproduced on the fabric without much distortion; in other words, the pattern is hardly distorted. It is particularly suitable for finely textured and/or elegant patterns, which can appear on textiles as something close to the image. Therefore, it is important that the reversibility of the pattern appearance of cut foil is such that the texture of the pattern is consistent on the front and back sides.

Conventional technology and its problems However, until now, no method has been developed to industrially ensure that the patterns on the front and back sides of paper cut foils not only match the design, but also match the color texture on both sides. However, there is a problem in that it is not possible to fully utilize the usefulness of this type of cut foil material due to the aforementioned properties.

Therefore, the inventors of the present invention aimed to create a symmetrical pattern on the front and back sides of the cut foil material using the above-described printing or stamping method, and in addition to matching the pattern on the front and back sides, the inventors also sought to improve the texture of the color. We conducted various studies to make the two sides consistent, but in the process we encountered the following problem.

Theoretically, a roll or rotary screen for printing or imprinting a pattern can be created, one for the front side and the other for the back side of the drawing lines that have a mutually symmetrical pattern, and these can be used to print or imprint the cut foil material. If a pattern is applied to the front and back sides of a paper, the color and texture of the front and back patterns should be the same, but when we actually tried this, we were able to make the density and ink density of the printing ink the same on two rolls or rotary screens. However, it was inevitable that the textures of the colors of the front and back patterns would be inconsistent.

As a result of investigating the cause of this, the inventors of the present invention found that the photoengraving method, which is one of the best plate-making methods in terms of faithfulness in copying the drawing line pattern to the original, was used to achieve the highest precision possible industrially. Even if two rolls or rotary screens are made underneath, the halftone dots or holes in the line pattern between the two rolls or rotary screens may differ slightly in one or more of size, density, and depth. It was discovered that this was the cause of the inconsistency in the texture of the hues of the front and back patterns.

The present invention was completed based on such knowledge and through repeated research and experiments.The purpose of the present invention is to match not only the patterns on the front and back sides, but also the texture of the colors on the front and back sides. The method described above is particularly suitable when the pattern is an abstract painting and has a blurred pattern, and can easily match the texture of the hues of the front and back patterns. The purpose of the present invention is to provide a method for manufacturing cut foil material by printing or stamping.

Means for Solving the Problems The above-mentioned object of the present invention is to create a monochromatic, plane-symmetrical pattern on the front and back sides of a cut foil material by a printing or stamping method using a printing or stamping roll or a stamping rotary screen. A method for manufacturing cut foil original fabric, in which a roll or rotary screen having a front-back symmetrical pattern with the circumferential direction of the roll or rotary screen as the front-back direction is applied, and the roll or rotary screen is A pattern is applied to the surface of the cut foil raw material using a screen, and then the left and right orientation of the roll or rotary screen with respect to the cut foil raw material with the pattern on the surface is the same as in the surface pattern application, and the material is Or a cut foil characterized in that a roll or rotary screen is placed in a state where the roll or rotary screen is substantially on the back side of the material, and a pattern is applied to the back surface of the cut foil raw material by the roll or rotary screen. This is achieved by the manufacturing method of the original fabric.

In the present invention, when applying a pattern to the back side of a cut foil original material, setting the deployment state of the material, roll, or rotary screen on a predetermined side under a predetermined orientation of the roll or rotary screen with respect to the material is generally performed. To do this, the direction of the roll or rotary screen is reversed left and right from when the surface pattern was applied, and the cut foil material is reversed from front to back with the same front and back relationship as when the surface pattern was applied, and the back side is the side of the roll or rotary screen. Alternatively, the left and right orientations of the roll or rotary screen and cut foil raw material can be left as they were when the surface pattern was applied, and the cut foil raw material can be arranged so that its back side faces the roll or rotary screen side. This can be done by

In the present invention, the alignment of the back surface pattern with respect to the surface pattern of the cut foil original material may be performed by any suitable method known per se.

Effects According to the present invention, a roll or rotary screen that applies a pattern to a paper-cut foil material by printing or imprinting is applied to a roll or rotary screen that has lines with a pattern that is symmetrical in the circumferential direction of the roll or rotary screen. , apply a pattern to the surface of the cut foil raw material using the roll or rotary screen, then set the left and right direction of the roll or rotary screen relative to the cut foil raw material in a predetermined direction, and set the material (or roll or rotary screen) By applying a pattern to the back side of the paper-cut foil material using the roll or rotary screen in a manner that matches the surface pattern under the predetermined deployment condition, the front and back sides of the paper-cut foil stock material are printed using the same roll or rotary screen. A pattern is applied to the paper, and the resulting paper cut foil is reversible, with a symmetrical design on both sides.

That is, according to the present invention, it is possible to reversibly apply a predetermined pattern to the front and back sides of the paper-cut foil material using the same roll or rotary screen, so that the pattern can be reversibly applied to the front and back sides of the paper-cut foil material. Unless the density and degree of ink coverage of the printing ink (or printing paste) are changed in printing or printing on the front and back sides, the pattern will appear as having the same hue and texture on the front and back sides. Furthermore, this desirable result can be easily achieved by using the same roll or rotary screen for forming the pattern on the front and back sides.

Effects of the Invention As described above, according to the present invention, it is actually guaranteed industrially that the patterns on the front and back sides not only match the design, but also the texture of the colors on the front and back. It is possible to provide a method for producing a cut foil material using the printing or stamping method described above, which is particularly suitable for a pattern with shading and shading, and which can easily match the texture of the hues of the front and back patterns.

Furthermore, according to the present invention, if the predetermined orientation of the roll or rotary screen with respect to the cut foil original fabric material and the predetermined arrangement of the material, roll, or rotary screen are followed during back pattern construction, the right side of the roll or rotary screen (or The left) side will be printing or stamping on both the front and back of the paper cut foil material on the right (or left) side.
The front and back patterns are applied symmetrically in the axial direction of the roll or rotary screen, that is, on the same side. Therefore, even if the pattern to be applied to the cut foil material has different gradations in the axial direction of the roll or rotary screen, the pattern can be applied to the roll or rotary screen with a line pattern of the corresponding gradation, and the color tone can be adjusted. The texture of the fabric can be expressed as one that matches the front and back patterns.
