Abstract

PURPOSE:To obtain a raw sheet printed with patterns on the top and reverse faces in such a manner as to agree the shape and color of the patterns with each other by applying a pattern on the top face of a raw sheet of a slit foil with a roll engraved with a pattern having symmetricity with respect to the circumferential direction of a printing roll and applying the same pattern on the reverse face while keeping the direction of the roll relative to said raw sheet and placing the roll to the reverse side of the raw sheet. CONSTITUTION:Patterns a, a', b, b' are applied to a surface of a raw sheet 4 of a slit foil using a roll engraved with patterns a, a', b, b' having a line symmetricity with respect to the circumferential direction (transfer direction) of a printing roll or a printing rotary screen 1. The right and left of the roll 1 are inverted relative to the state of the application of the obverse and reverse patterns and the obverse and reverse faces of the sheet 4 are inverted to position the roll 1 on the reverse side. As an alternative method, the lateral directions of the roll and the sheet are maintained in the state of the application of pattern to the obverse and reverse faces and the roll is placed to the reverse side of the raw sheet 4 while keeping the direction of the roll in the state of the application of the surface pattern. A pattern is applied to the reverse face to obtain the objective raw sheet of a slit foil having patterns a, a' at the obverse left side of the raw material 4 and patterns b, b' on the right side of the material. The patterns b, b' applied to the reverse right face are matched with the patterns a, a' applied to the left side of the material. The color tones are also matched between the obverse and reverse faces.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a cut foil material, that is, a kind of material for obtaining cut foil by slitting it into narrow widths, in particular, 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 H using such printing or stamping methods, the cut foil material H can be made with patterns on the front and back sides by pasting together materials that have previously shown the pattern. In addition to being superior in productivity, it is easier to align the front and back crosspieces.

It is important that the patterns on the front and back sides of cut foil originals with patterns on both sides match not only the designs but also the textures of the colors on both sides.

Generally, the reason why a cut foil material is made into a double-sided pattern that is plane symmetrical on the front and back is that when the cut foil obtained by slitting it is woven into it during textile weaving, the pattern element (the pattern element (the slit) 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. 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 delicate and/or elegant patterns that can appear on textiles as similar to images. Therefore, it is important that the pattern appearance of cut foil is reversible, so that the texture of the pattern is consistent between the front and back.

Conventional technology and its problems However, no method has yet been developed to industrially guarantee that not only the design but also the texture of the hues on the front and back sides of paper cut foil sheets will match. 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 its front claw characteristics.

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. Even though
This resulted in an inconsistency in the texture of the colors of the front and back patterns.

As a result of investigating the cause of this, the inventors of the present invention discovered that the method of photoengraving, which is one of the best plate-making methods in terms of faithfulness in copying the drawing line pattern to the original, has been made with the highest precision possible industrially. Even if two rolls or rotary screens are made, there will be halftone dots or holes in the line pattern between the two rolls or rotary screens.
Subtle differences in one or more of size, density, and depth,
It was determined 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 this knowledge through further 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 front claw printing method is particularly suitable when the pattern is an abstract painting and has a blurred pattern, and it is possible to easily match the texture of the hues of the front and back patterns. Another object of the present invention is to provide a method for producing a cut foil material using a stamping method.

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 paper-cut foil material by a printing or stamping method using a printing or stamping roll or a stamping rotary screen. A method for producing a 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 raw material, the setting of 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 as follows: For fishing,
The direction of the roll or rotary screen is reversed from side to side when the surface pattern is applied, and the cut foil material is reversed from front to back in the same front-to-back relationship as when the surface pattern is applied, so that the back side is on the side of the roll or rotary screen. Or, by keeping the left and right orientations of the roll or rotary screen and cut foil raw material as they were at the time of surface pattern construction, and placing the cut foil raw material so that its back side faces the roll or rotary screen. good.

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.

Function According to the present invention, as a roll or rotary screen that applies a pattern to a cut foil raw material by printing or stamping,
In order to apply a pattern that has symmetrical patterns on the front and back in the circumferential direction, a pattern is applied to the surface of the cut foil raw material using the roll or rotary screen, and then the roll or With the rotary screen facing left and right in a predetermined direction and the material (or roll or rotary screen) being arranged in a predetermined manner, a pattern is created on the back side of the cut foil raw material using the roll or rotary screen. By matching the positions with the paper cut foil material, the same roll or rotary screen can be used to create a pattern on both sides of the cut foil material, and the obtained cut foil material is reversible with a symmetrical pattern on the front and back sides. It is something.

That is, according to the present invention, a predetermined pattern can be reversibly applied to the front and back sides of the cut foil material using the same roll or roller screen, so that the front and back sides printed or stamped on the cut foil material can be reversibly applied. 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 pattern on the front and back sides not only matches the design (but also the texture of the color and texture), and therefore the pattern becomes abstract and artistic. 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 front and back patterns are printed or stamped on the right (or left) side on both the front and back sides of the cut foil material, so that the front and back patterns are symmetrical in the axial direction of the roll or rotary screen. done on the same side. Therefore, even if the pattern to be applied to the paper cut foil material has different gradations in the axial direction of the roll or rotary screen, the pattern can be applied to a roll or rotary screen with a line pattern of the corresponding gradation, and the tone will be different. The texture can be expressed as matching the front and back patterns.
