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. Multicolor printing or printing of two or more colors, that is, multicolor overprinting or printing (hereinafter abbreviated as multicolor overprinting except as described in "Means for solving problems"). Concerning the manufacturing method of paper cut foil that exhibits symmetrical patterns.

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.

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 sides is that when the cut foil obtained by slitting it is woven during weaving of textiles, the pattern element (the above slit is (The pattern is subdivided)
Even if the part is turned over, the pattern element on the back side occupies the front side.
This is to make it a kind of reversible. 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 delicate and/or graceful patterns that can be expressed on textiles as similar to the original 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, no method has yet been developed to industrially guarantee that the patterns on the front and back sides of multi-color overprinting will match not only the design but also the texture of the hues on both sides of paper cut foil sheets. Therefore, there is a problem in that the usefulness of this type of cut foil material due to the aforementioned characteristics cannot be fully utilized.

Therefore, the inventors of the present invention have created a planar symmetrical pattern of multicolor overprinting on the front and back sides of the paper-cut foil material by using the above-described printing or stamping method. We have conducted various researches to make the texture of the color match both front and back, but
In the process, I encountered the following problem.

Theoretically, it can be used as a color-coded roll or rotary screen for printing or imprinting patterns.
If you create a pattern for the front side and a pattern for the back side of the drawing lines that are symmetrical to each other, and use these to create a multicolor overprint pattern on the front and back sides of the cut foil material, the colors and textures of the front and back patterns will be the same. However, when we actually tried this, we found that even if the printing ink density and ink coverage were the same on the front and back rolls or rotary screens for each color, the texture of the hue of the front and back patterns was inconsistent. forced into alignment.
In particular, in the case of multi-color overprinting of three or more colors, the texture mismatch between the front and back patterns is significant.

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 multicolor overprinting of the front and back patterns.

The present invention was completed based on these findings through further research and experimentation.The purpose of the present invention is to improve not only the matching of the designs but also the hue of the multicolor overprinted patterns on the front and back sides. It actually ensures industrially that the texture is consistent between the front and back sides, and is therefore particularly suitable when the pattern is an abstract painting and a pattern with shading, and it is also possible to easily match the texture of the hues of the front and back patterns. It is an object of the present invention to provide a method for producing a cut foil material using the printing or stamping method described above.

Means for Solving the Problems The above-mentioned object of the present invention is to print plane-symmetrically on the front and back sides of the cut foil material by printing in different colors, overprinting in multiple colors using a printing roll or printing rotary screen, or by printing. A method for manufacturing a cut foil original fabric exhibiting a pattern, wherein the roll or rotary screen has a pattern line that is symmetrical in the front and back, with the circumferential direction of the roll or rotary screen being the front and back direction. , applying a pattern to the surface of the cut foil raw material using the roll or rotary screen,
After that, the left and right orientation of the roll or rotary screen with respect to the cut foil raw material with a pattern on its surface is the same as in the surface pattern construction, and the material, roll, or rotary screen is placed against the material with the roll or rotary screen. Under the specifications that the rotary screen is placed on the back side and the pattern is applied to the back side of the cut foil material using the roll or rotary screen, the above-mentioned information for each color is applied for multicolor overprinting or printing. This is achieved by a method for producing cut foil material, which is characterized by applying the pattern using a roll or rotary screen.

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) Under the specifications that a pattern is applied to the back side of the cut foil raw material using the roll or rotary screen in a manner that matches the surface pattern in a predetermined deployment state,
For multi-color overprinting, by applying patterns using separate rolls or rotary screens for each color, patterns can be created on the front and back sides of the cut foil material using the same roll or rotary screen for the same color, and the resulting cut foil material The fabric is reversible, with a symmetrical design on both sides.

That is, according to the present invention, a predetermined pattern of the same color can be reversibly applied to the front and back sides of the cut foil raw material using the same roll or rotary screen, so that it is possible to reversibly apply a predetermined pattern to the front and back sides of the cut foil raw material. The pattern on the front and back sides will appear consistent on the front and back sides unless the density and ink density of the printing ink (or printing paste) are changed in the printing or printing on the front and back sides. That will happen. 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 not only the patterns on the front and back sides match, but also the texture of the hue of multicolor overprinting matches on the front and back sides. To provide a method for producing a cut foil original fabric by the above-described printing or stamping method, which is particularly suitable when the pattern is abstract and has a blurred pattern, and which can easily match the texture of the hues of the front and back patterns. This is possible.

Furthermore, according to the present invention, according to the predetermined orientation of the roll or rotary screen with respect to the cut foil raw material element and the predetermined arrangement of the material, roll, or rotary screen at the time of backside pattern construction, the right side of the roll or rotary screen (or The front and back sides are symmetrical in the axial direction of the roll or rotary screen, so that both the front and back sides of the cut foil material are printed or stamped on the right (or left) side. done 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
By using a roll or rotary screen with a line pattern of corresponding gradation, the texture of the hue can be expressed as matching the front and back patterns.
