Description

  The present invention relates to a method and apparatus for producing a printed matter having a changed gloss, a method for processing the surface of a pressure roll used for producing such a printed matter, and a printed matter produced by the production method.

Traditionally, technology has been developed to change the gloss, brightness, and hue (hue) of printed matter. Generally, special processing is required, so the effect of preventing counterfeiting and imitation can be obtained. The effect which improves the commercial property of printed matter by the point which gives is obtained.
For example, in Patent Document 1, a light interference fringe recorded on a photosensitive material is formed as an uneven interference fringe on a mold, and a light interference fringe uneven pattern is formed on the heat-resistant film surface from the mold. A metal such as aluminum is vapor-deposited on a film having an uneven pattern of light interference fringes to form a reflective rainbow hologram, and a thermoplastic resin is applied to a part or the entire surface of the printed material in the form of a film. Heat the metal vapor deposition surface, press the metal vapor deposition surface to the thermoplastic resin film on the surface of the printed material, peel off the rainbow hologram after cooling, and transfer the rainbow hologram to the thermoplastic resin film on the surface of the printed material The technology is described.

  Further, Patent Document 2 discloses that a base layer is formed by printing arbitrary characters, designs, and the like on a base material with colored ink, and the uneven pattern is printed on the base layer with a transparent ink. A technique is described in which a transparent layer having uneven lines that are fine parallel line patterns is formed on the surface of the pattern so that the glossiness of the transparent layer slightly changes depending on the observation angle. In this technique, a glossy feeling adds a sense of luxury and interest, and the presence of the transparent layer protects the surface of the underlayer. In addition, since the transparent layer is made of transparent ink, characters and designs printed on the underlying layer can be surely seen, and the transparent layer cannot be reproduced even if copied, so it has an anti-counterfeit effect. is there.

In Patent Document 2, as a technique for forming a transparent layer, it is described that the transparent layer is formed by printing a transparent ink on the surface of the underlayer so as to have a predetermined thickness. It is described that flexographic printing, silk screen printing, and the like that can be printed so as to deposit ink are suitable.

According to the apparatus for producing a printed matter of the present invention (Claim 22), the uneven pattern is reliably formed on the surface of the printed matter while performing printing and applying the transparent resin easily by using offset printing. The gloss, brightness, and hue of the printed material change, and the product quality of the printed material can be improved.

Yes. In addition, although the uneven | corrugated line is normally formed by the smooth uneven | corrugated curved surface, it does not necessarily need to be a smooth curved surface.

  The uneven lines 2 are ridges (convex portions) or grooves (concave portions) having a width equal to or less than a visible light wavelength (780 nm) to be a diffraction grating and periodically present. The depth is also set to a visible light wavelength (780 nm) or less. The concavo-convex pattern 3 is a ridge (projection) or a groove (concave) that has a width of 1 to 10 μm and periodically exists, and the height of the ridge or the depth of the groove is also the width (1 to 10 μm). It is set as follows.

In addition, although the uneven | corrugated line 2 and the uneven | corrugated pattern 3 can express that it is formed with a protruding item | line or a concave groove, it demonstrates below as what is formed with a protruding item | line.

Is set to On the other hand, as for the uneven | corrugated line 2, the direction of each protrusion is set to the fixed direction over the whole surface.

However, the area division of the concavo-convex pattern 3 is not limited to the polygonal shape as described above, and a circle, an ellipse, or the like may be combined. Also, for the uneven line 2, the direction of each ridge is not made constant over the entire surface, but according to the area division of the uneven pattern 3 or in units of areas unrelated to the area division of the uneven pattern 3, The direction of each ridge may be set separately.
Further, here, each ridge constituting the concavo-convex pattern 3 and each ridge constituting the concavo-convex line 2 are also formed in a straight line in front view, but either or both of these are also formed in front view. It may be formed in a curved shape (for example, a wavy line), or each ridge may be configured by combining a straight line and a curved line in both the uneven pattern 3 and the uneven line 2. .

  Moreover, about the uneven | corrugated pattern 3, it is also preferable not only to give a change to the direction of a protruding line in a different area | region but to give a height change in each area | region, or to change the period and amplitude of a protruding line. .

The sheet is guided so as to move in a state where the surface thereof is directed to the blanket cylinders 21b, 22b, 23b, 24b, and 32 (upward).
The first drying unit 40 includes a UV drying device 41 for drying the transparent resin in a non-contact manner by irradiating the surface of the printing paper coated with the transparent resin with ultraviolet rays. However, the drying of the transparent resin in the first drying unit 40 is performed in a semi-dried state so that the pressing process of the uneven pattern having uneven lines in the uneven process part 50 in the next process can be performed satisfactorily. stop. The semi-dry state means a dry state where the transparent resin is dried to such an extent that the transparent resin does not adhere and is slightly cured to a deformable flexible state.

  In the first drying unit 40, instead of the UV drying device 41, hot air (or hot air) drying is performed to dry the transparent resin in a non-contact manner by spraying hot air or hot air onto the transparent resin on the surface of the printing paper. For example, an apparatus may be used, for example, a heating and drying apparatus that heats and drys the transparent resin by supplying heat to the peripheral surface of the impression cylinder 33 of the transparent resin coating unit 30 and heating the back surface of the printing paper may be used. Alternatively, any or all of these may be used in combination.

  The concavo-convex portion 50 includes a pressure roll 51 and a counter roll 52. As shown in FIG. 3, the pressure roll 51 has an outer peripheral surface 51 a with a concavo-convex shape, and presses the concavo-convex outer peripheral surface 51 a against the surface of the semi-dried transparent resin so that the surface of the transparent resin has an uneven surface. An uneven pattern having lines is formed. In FIG. 3, for the sake of convenience, the uneven shape of the outer peripheral surface 51 a with the uneven shape is greatly enlarged and exaggerated than the actual one. As shown in FIG. 2, the opposing roll 52 is sandwiched between the pressure roll 51 and the printing paper, and supports the printing paper from the back side when the pressure roll 51 is pressed against the transparent resin surface. A transfer drum 25f is also interposed between the pressure drum 33 and the counter roll 52 so that the printing paper moves through the transfer drum 25f with the surface facing the pressure roll (upward).

Is dried by irradiating the transparent resin on which the uneven pattern on the surface of the printing paper is formed.

  In the second drying unit 60, instead of the UV drying device 61, hot air (or hot air) drying is performed in which the transparent resin is dried in a non-contact manner by spraying hot air or hot air onto the transparent resin on the surface of the printing paper. An apparatus may be used, for example, a heating and drying apparatus that heats and dries the transparent resin by supplying heat to the peripheral surface of the drying roll 62 and heating the back surface of the printing paper, or any of these may be used. Or they may be used in combination.

Although not shown in the drawings, the paper discharge unit 70 includes a paper discharge cylinder, a conveyance chain, and a pile lifting device from the upstream, and prints a printed sheet in which a concavo-convex pattern is processed on a transparent resin that has been printed and applied to the surface. It is transported while being locked by a gripping claw (not shown) mounted on the pile and sequentially stacked on a pile lifting device.
For example, when the printing press is operated at high speed, if the drying process in the second drying unit 60 does not sufficiently dry the transparent resin, the printing sheet is transported along the transport chain downstream of the discharge cylinder. In addition, a drying device such as a UV lamp (ultraviolet lamp) may be provided as a drying device for drying the printing surface of the printing sheet, and the mirror surface printing ink may be quickly dried even at high speed operation.

  Further, as a heating means for heating the transparent resin by supplying heat to the peripheral surfaces of the pressure drum 33 and the drying roll 62 described above, for example, a heating wire is incorporated inside the pressure drum 33 and the drying roll 62. The structure which dries transparent resin to a required dry state by adjustment of the electric power supplied to a heating wire can be considered.

<Processing of pressure roll surface>
By the way, as shown in FIG. 3, the pressing roll 51 provided in the concavo-convex portion 50 is provided with a concavo-convex shape to form a concavo-convex pattern 3 having fine concavo-convex lines 2 on the surface 1 a of the printed material 1. The outer peripheral surface 51a has an outer peripheral surface 51a. The outer peripheral surface 51a with the concave and convex shapes is first struck with a mold corresponding to the concave / convex pattern 3 without the concave / convex lines 2, and then according to the concave / convex pattern 3. It is formed by carving slits corresponding to the concave and convex lines 2 by plastic deformation on the processed cylinder surface by a ruling engine.

  In order to process the uneven shape on the surface of the pressure roll 51, that is, the unevenness corresponding to the uneven pattern 3 and the uneven line 2, in addition to this, direct processing by laser, photoresist, exposure, development, and etching are performed. The method of performing in order can be applied. Also in the case of applying these processing methods, a method can be used in which a concavo-convex shape corresponding to the concavo-convex pattern 3 without the concavo-convex line 2 is first processed and then slits corresponding to the concavo-convex line 2 are engraved. For example, when a laser is used, it is also possible to directly process the uneven pattern 3 with the uneven lines 2 (in one step).

Moreover, in the processing method of the pressure roll surface of this embodiment, after processing the uneven | corrugated shape concerning the surface of the pressure roll 51, the surface treatment process which processes this surface is performed. This surface treatment includes a cured film forming process for forming a cured film and a release film forming process for forming a release film for improving the release property of the transparent resin. In this embodiment, both processes are performed. .
As the curing process in this case, for example, a surface nitriding process or a chrome plating process can be applied. Moreover, as a release film formation process, the thin film coating by a silicone resin and the thin film coating by a fluororesin can be applied, for example (in this case, it can call a mold release agent application | coating process).

  In addition, ballistic plating is applied to aluminum or iron cylinder equipment, then copper plating is performed, and the surface is finely processed to form an uneven shape (uneven pattern 3 with uneven lines 2). In this case, since the copper plating surface can be easily peeled off, an aluminum or iron cylinder can be reused.

<Manufacturing method of printed matter with changing gloss>
Since the printed matter manufacturing apparatus according to the first embodiment of the present invention is configured as described above, the gloss changes by the following technique (the method for manufacturing a printed matter with a changed gloss according to the present embodiment). Printed materials can be manufactured.
That is, as shown in FIG. 1, four colors c, m, y, and k are applied to the printing paper transferred from the paper feeding unit 10 to the printing unit 20 by the printing units 21, 22, 23, and 24 of the printing unit 20. Ordinary color printing is performed using the process ink (step S10, printing process).
Next, the printed printing paper is transferred to the transparent resin application unit 30, and the transparent resin is applied to the surface by offset printing (step S20, transparent resin application process). That is, a transparent resin (UV varnish) that is cured by ultraviolet rays is applied to the surface of the printing paper immediately after color printing by the transparent resin application unit 30 using an offset printing method.

  Further, the printing paper coated with the transparent resin is transferred to the first drying unit 40, and the coated transparent resin is semi-dried (step S30, semi-drying step). That is, the first drying unit 40 uses the UV drying device 41 to irradiate the surface of the printing paper coated with the transparent resin with ultraviolet rays, thereby drying the transparent resin in a non-contact manner. However, the drying of the transparent resin in the first drying unit 40 is kept in a semi-dry state, that is, a dry state in which the transparent resin is dried to such an extent that the transparent resin does not adhere and is slightly hardened to a deformable flexible state.

  Next, the printing paper semi-dried with the transparent resin on the surface is transferred to the concavo-convex processing section 50, and the concavo-convex pattern is pressed on the surface of the semi-dried transparent resin (step S40, concavo-convex processing step). That is, the printing paper is passed between the pressure roll 51 and the counter roll 52 of the concave and convex portion 50, and the outer peripheral surface 51a with the concave and convex shape of the pressure roll 51 is pressed against the surface of the semi-dried transparent resin. Then, an uneven pattern 3 having uneven lines 2 is formed on the surface of the transparent resin.

In addition, at the time of this uneven processing, in the semi-drying process in the immediately preceding first drying unit 40, since the transparent resin is dried to such an extent that the transparent resin does not stick and is in a dry state that is hardened to a deformable flexible state. In addition, the concave / convex pattern 3 having the concave / convex lines 2 is formed with high accuracy according to the shape of the outer peripheral surface 51 a with the concave / convex shape of the pressure roll 51 without the resin adhering to the pressure roll 51.
Next, the printing paper in which the concavo-convex pattern 3 having the concavo-convex lines 2 is pressed on the surface of the transparent resin is transferred to the second drying unit 60 and is run along the outer periphery of the drying roll 62, while UV. The transparent resin on which the uneven pattern 3 on the surface of the printing paper is irradiated with ultraviolet rays from the drying device 61 is dried (step S50, drying process).
Thereafter, the printing paper dried with the transparent resin is transferred to the paper discharge unit 70 and sequentially stacked on the pile lifting device.

Thus, according to the printed material manufacturing apparatus and manufacturing method according to the present embodiment, the transparent resin coating unit (transparent resin coating device) 30 and the first drying unit (on the downstream side of the printing unit of a normal offset printing machine) Only by adding a first drying device) 40, a concavo-convex processing section (concave processing apparatus) 50, and a second drying section (second drying apparatus) 60, or a transparent resin coating process, a semi-drying process, By simply adding the irregularity processing step and the drying step, it is possible to easily produce a printed matter whose gloss changes.

Moreover, in the transparent resin application process by the transparent resin application part 30, since the transparent resin is applied by offset printing, printing and application of the transparent resin can be easily performed using an offset printer.
Moreover, since the irregularities are pressed on the surface of the transparent resin in a semi-dried state of the transparent resin, it is possible to reliably form an irregular pattern having irregular lines that are fine parallel line patterns on the surface of the printed matter. The gloss, brightness, and hue of the printed material change, and the merchantability of the printed material can be improved.

In the case of the present embodiment, by pressing the concavo-convex pattern 3 having the concavo-convex lines 2 using the pressure roll 51 having the concavo-convex outer peripheral surface 51a, it is quick and simple in a single process. In addition, it is possible to easily produce a printed matter having a changed gloss.
In the case of this embodiment, in the semi-drying process and the subsequent drying process, the transparent resin is semi-dried or fully dried by irradiation with ultraviolet rays. Therefore, the transparent resin can be dried in a short time, which is suitable for high-speed printing. .

The change can be further promoted, and the merchantability of the printed matter can be further enhanced (claim 6).
In the above embodiment, each ridge constituting the concavo-convex pattern 3 and each ridge constituting the concavo-convex line 2 are also formed in a straight line in front view. It may be formed in a curved line shape (for example, wavy line), or, for both the uneven pattern 3 and the uneven line 2, each protrusion is formed by combining a straight line and a curved line. However, it is possible to make the change in gloss, shine and color of the printed material unique and enhance the merchantability of the printed material.

In addition, for the uneven pattern 3, not only changes in the direction of the ridges in different regions, but also changes the height in each region, or changes the period and amplitude of the ridges, Productivity of printed matter can be improved.
