Description

  The present invention relates to a printed matter exhibiting a three-dimensional effect and a method for producing the printed matter.

  Conventionally, in the field of commercial printing, particularly in the packaging field, coating varnishing for applying a coating agent (also referred to as varnish in the industry) to a printed material, and mirror-finishing the varnished printed material for the purpose of cosmetic decoration and surface protection of the printed material Various surface treatments such as press processing for applying a specular gloss to a printed material by heating and pressing with a plate, and laminating processing for bonding a film such as OPP or PET to the printed material are performed.

  In recent years, more and more attempts have been made to differentiate from competitive products by imparting cosmetics that have never been seen before. This is because the package design and cosmetics greatly affect the sales of products.

  In particular, the application of visual effects to printed materials has a high effect of attracting consumers, so there are techniques that give glitter papers, unevenness (embossing), 3D (three-dimensional effect), etc. It is practically used.

  Among methods for imparting a visual effect, there are various methods exemplified below as means for three-dimensionally expressing characters and patterns of printed matter.

<Pseudo embossing>
Pseudo embossing uses a printing machine having an inline coater or the like to give a printed product a visual effect in which a three-dimensional effect can be easily felt.
A special underprinting UV (ultraviolet curable) primer varnish is printed on the embossing effect, and the UV clear varnish is applied over the entire surface. As the primer varnish, one having a property of repelling the clear varnish applied thereon is used.

The UV clear varnish overlapped with the UV primer varnish is repelled into droplets, forming fine irregularities and having a matte (matte) tone. The portion that does not overlap with the UV primer varnish is not repelled and becomes a uniform surface to form a glossy portion. The glossy part and the matte part thus formed give a visual effect as if a three-dimensional embossing process was applied to the printed matter.
Packaged products created with this method can feel a three-dimensional beauty when viewed nearby, but when viewed from a distance, or in a state where they are lined up on a display shelf with the same type of products. In, the embossing effect is difficult to recognize and can be said to be inferior in appeal.

<Rami coat processing>
This is a processing method that uses UV clear varnish to perform gloss processing, mat processing, hologram processing, etc. on the surface of printed matter. After the application of UV clear varnish, a film having a specific shape is superimposed on the surface, cured by UV irradiation over the film, and then the film surface is peeled off to transfer the shape of the film surface to the surface of the printed material.

  When a hologram film is used as a film to be used, a three-dimensional and glittering processed product can be obtained. In order to carry out these processes, special equipment such as a lami coat system and a casting system is required.

<Foil stamping>
This is one type of transfer printing, in which a foil for surface decoration or the like is formed on a transfer paper, and the foil is transferred by pressing against the object to be transferred from the back surface of the transfer paper. Common foil stamping includes hot stamping in which thermocompression bonding is performed with a mold and cold stamping in which foil is transferred using an adhesive. There are gold, silver, hologram, and the like as foil types used for foil stamping, and they are also used for bills, gift certificates, gift certificates, and the like in order to provide a forgery prevention function.
When this hologram film is used, a three-dimensional and glittering processed product can be obtained. In addition to the high cost of foil stamping, gold foil and silver foil are common in the market and their differentiation power is weak. Appealing hologram foils are expensive.

<3D (three-dimensional effect) processing using special fabric>
On the base material on which a special image for stereoscopic viewing is printed, an aggregate of kamaboko-shaped lenses called lenticular lenses and convex lenses called microarray lenses are formed to give the viewer a stereoscopic visual effect. The processing method that can be used is in practical use. Since this method uses a special lens assembly, material costs and processing costs are high.

Prior art documents related to the present invention will be described.
In Patent Document 1, a base material 1 having a smooth surface, a partial clear layer 2 provided to form characters and designs on the surface of the base material 1, and the base material 1 and the partial clear layer 2 are provided so as to be covered. The light reflective fine powder 4 having a particle size of 5 to 100 μm is composed of a transparent entire clear layer 6 mixed with 5 to 20% by weight, and the light reflectivity in a portion where the partial clear layer 2 is present and a portion where the partial clear layer 2 is not present. There is described a printed sheet having a three-dimensional effect, characterized in that the distribution density of the fine powder 4 is made different so that an uneven texture appears between the two parts.

When the light-reflecting fine powder having this particle size is added, there is a concern that problems such as plate residue and blank residue may occur in offset printing, and problems such as clogging may occur in silk screen printing.
Further, when the amount of powder added is increased in order to further enhance the effect, the printability is expected to deteriorate further, and there is a possibility that the plate or the blanket needs to be washed many times during printing.

  Patent Document 2 describes the principle of so-called Takumoto by placing a flexible printed sheet on the upper surface of a copper plate, an etching plate, a photosensitive resin plate, a wood plate, etc., with an uneven surface, and performing a silk screen from the upper surface. The pattern printing method used is described. In order to implement this, for example, it is necessary to engrave unevenness processing corresponding to characters and designs on the surface of a metal roll of a printing press, which may require considerable labor and cost.

  In Patent Document 3, a coating or printing ink containing light-reflective fine powder such as pearl mica or aluminum powder is applied to the entire surface of a printed material, and a conductive metal plate having a shape corresponding to a portion such as a character or a pattern. Is applied to the lower surface of the printed matter, and a high voltage is applied from the upper surface before the printing ink is dried, so that the distribution amount of the reflective pigment particles in the conductive metal plate portion and the other portions is reduced. Marks that are different and have a three-dimensional effect are described. To do this, a device for generating a high voltage is required.

Japanese Patent Application No. 5-264197 Japanese Patent Publication No. 1-19345 Japanese Patent Application No. 4-250763

  An object of the present invention is to provide a printed matter that can be produced at high speed, in large quantities, and at low cost, and that exhibits a three-dimensional effect, and a method for producing the printed matter.

  The inventor has a pattern B in which letters and pictures are formed with ink or varnish on the surface of the base material A having a smooth surface, and a pattern that is partially or entirely identical to the pattern B and formed with ink or varnish. A printed matter having a positional relationship in which part or all of the pattern C is deviated from the pattern B is that the observer can feel a three-dimensional effect, and a special material or The present invention was completed by finding that it can be produced at high speed, in large quantities and at low cost without using a production method.

  As one of the methods for producing the printed matter of the present invention, there is a method in which the pattern B is formed on the surface of the substrate A by offset printing, and further, the pattern C is formed by offset printing or a coater.

  The positional relationship in which the pattern B and the pattern C are shifted means that the pattern B and the pattern C are not completely overlapped.

  The shift amount of the pattern C with respect to the pattern B is preferably 2 to 95%, more preferably 5 to 70%, and still more preferably 15 to 50%.

  There is no particular limitation on the direction (degree) of displacement of pattern C with respect to pattern B. The effect of moving in other directions is more effective than moving to the top and bottom and moving left and right (in this case, the angle in the direction of deviation is 0, 90, 180, 270, or 360 degrees). There is a high tendency.

  As the pattern B and / or the pattern C, a transparent one having a difference in gloss, that is, a glossy varnish or a mat varnish can be used. The gloss difference between the pattern B and the pattern C is preferably 0.1 to 95, more preferably 3.00 or more.

  When the pattern B and the pattern C are to be differentiated by color shading (density), they can be adjusted by changing the amount of ink or the halftone dot% of printing. The density difference between the pattern B and the pattern C is preferably 0.10 to 2.00, more preferably 0.30 or more.

The printed matter of the present invention can be produced using a normal printing method and printing material without using embossing or a special composition varnish, and the printed matter gives a three-dimensional impression to the observer.
The printed matter has an effect of attracting what is visually seen, and can be suitably used for a product packaging material, a paper container package, a poster, and the like.

An example of the printed matter with a three-dimensional effect in the present invention is shown. Both pattern B and pattern C are simply shown as squares. The pattern B and the pattern C are the same picture, but in this figure, the pattern B is hatched for the sake of convenience for easy discrimination. In this example, the pattern C is shifted from the pattern B by about 25% in the direction of −45 degrees at the lower right. Another example of a three-dimensional printed material according to the present invention will be described. Pattern B and pattern C are both patterns based on the letter K. In order to make the distinction easier, the pattern B is hatched for convenience. In this example, the pattern C is shifted in the lower right direction with respect to the pattern B. The display of the shift amount of the pattern C with respect to the pattern B in this specification will be described. Pattern B and pattern C are the same pattern, and the overlapping state is 0%, the half-overlapping state is 50%, and the next one is 100%. The pattern B and the pattern C are the same picture, but in this figure, the pattern C is hatched for the sake of convenience for easy discrimination. (A) of the figure shows a state in which the pattern C is shifted by about 25% in the right direction (angle 0 degree). (B) of the figure shows a state where the pattern C is shifted by about 50% in the right direction (angle 0 degree). In this specification, the display of the direction of deviation of the pattern C with respect to the pattern B will be described. The deviation direction means a direction in which the pattern C is shifted with respect to the pattern B, and is represented by an angle. In FIG. 5A, the pattern C is shifted in the direction of about 45 degrees. In FIG. 5B, the pattern C is shifted in the direction of about −45 degrees (or about 315 degrees). The amount of deviation is about 50% in all cases. It is a figure which supplements about the display of the deviation | shift amount of the pattern C with respect to the pattern B in this specification. When the pattern B and the pattern C are a combination of a pattern and various characters, etc., the amount of deviation differs depending on the location as shown in FIG. In such a case, the position where the amount of deviation is the smallest (that is, the place where the pattern is the largest and the main part) is taken as the amount of deviation between Pattern B and Pattern C. In this figure, when only the part surrounded by the broken-line circle is viewed, it seems that it is shifted by 100% or more when considered based on the example of FIG. However, in the pattern of this figure, the square part is considered as the main part, and is assumed to be shifted to the lower right by about 25%.

  The printed matter of the present invention forms a pattern B composed of letters and pictures with ink or varnish on the surface of the substrate A having a smooth surface, and part or all of the pattern B is the same as the pattern B with the ink or varnish. C is formed so that part or all of the pattern C is relatively shifted from the pattern B.

  As described above, the pattern B and the pattern C are partially or entirely the same in characters and patterns, but the ink and varnish used for forming each pattern may not be the same. The embodiment of the present invention includes the case where all or a part of the ink and varnish used are the same or different.

For example, the pattern B may be formed as a red pattern using red ink, and the pattern C may be formed as a transparent pattern having a gloss or glossiness different from that of the substrate using a transparent varnish. Included in the embodiment.
As another example, the pattern B is a pattern made of black characters using black ink, the pattern C is a pattern made of light black characters partially the same as the characters of the pattern B, and the pattern C is Forming at a position shifted from the pattern B is also included in the embodiment of the present invention.

  Depending on the positional relationship between the pattern B and the pattern C, overlapping of patterns (patterns, characters, etc.) may occur, but these overlapping portions may form only one pattern or may overlap.

  Various printing methods such as offset printing (lithographic printing), intaglio printing, relief printing, stencil printing, and ink jet can be used as the printing method for pattern B and pattern C. When printing in large quantities, offset printing is preferably used.

  As the base material A, a substrate on which a pattern or a character has already been printed, a solid-printed one, a colored one, or the like can be used as necessary. The substrate A may not be printed.

When varnish is used to form the pattern B and the pattern C, a pattern that appears to float from an arbitrary base color can be produced due to a difference in gloss or the like. When using a varnish, the visual effect which can feel a three-dimensional effect is good if the gloss difference is in the range of 0.1-95. The gloss difference is more preferably in the range of 1.00 to 60.00.
In the present specification, the gloss value is a micro tri gloss gloss meter No. manufactured by Big Gardner. This is a value measured using the 4520 reflection setting at 60 degrees.

  The amount of deviation between the pattern B and the pattern C is preferably 2 to 95%, more preferably 5 to 70%. More preferably, it is 15 to 50%.

  In this specification, the amount of deviation is defined as 0% when the pattern B and the pattern C are the same pattern and overlapping, 50% when the pattern overlaps half, and 100% when adjacent to the pattern C.

The shift direction in this specification means a direction in which the pattern C is shifted with respect to the pattern B, and is represented by an angle.
The description about the amount of deviation and the direction of deviation (angle) is shown in FIGS.

  For the formation of the pattern B and / or pattern C, a soft touch varnish imparting a sensory effect can be used. In this case, in addition to the three-dimensional visual effect, a sensory effect on the tactile sensation can be imparted.

When using a color ink or varnish that is not colorless and transparent, the visual effect of feeling a three-dimensional effect is often excellent when the pattern B and the pattern C are formed of similar color materials. Further, by providing a density difference between the pattern B and the pattern C, the stereoscopic effect can be enhanced. The optimum density difference and density value vary depending on the color used.
Here, the density refers to the reflection density of the printed matter and is optically measured with a densitometer. The density value in this specification is measured using a spectroeye spectrocolorimeter manufactured by X-Rite.

When using a varnish, the visual effect is good if the pattern B and the pattern C are formed of the same system, that is, a combination of a mat-type varnish or a combination of a gloss-type varnish. However, the combination of mat and gloss can give a three-dimensional effect. Further, by adding a gloss difference between the pattern B and the pattern C, the stereoscopic effect can be enhanced.
Here, the mat type refers to a varnish that has a matt appearance, and the gloss type refers to a varnish having a glossy surface.

The present invention will be described in detail by examples.
In the following experiments, as described above, the gloss measurement was conducted by using a micro tri gloss gloss meter No. 4520 was used with a 60-degree reflection setting.
As described above, the concentration measurement was performed using a spectroeye spectrocolorimeter manufactured by X-Rite.

<Evaluation method of three-dimensional effect>
On the surface of the base material A having a smooth surface, there are a pattern B in which letters and pictures are formed by ink or varnish, and a pattern C that is partially or entirely identical to the pattern B and formed by ink or varnish. Then, the pattern C creates a printed material having a positional relationship in which part or all of the pattern C is shifted, and the printed material is attached to the wall surface. It observed visually from the place 1 m away, and evaluated the extent which feels a three-dimensional effect in the 100-point perfect score.
