Description

TECHNICAL FIELD The present invention relates to a printed matter, a decorative sheet, a method for producing a printed matter, and a method for producing a decorative sheet, which have a high degree of designability by matching a clear ink pattern with a colored ink pattern. .

Conventionally, mainly in gravure printing, in addition to pattern printing with colored ink that forms the pattern, design and performance are added by forming a transparent ink with high or low gloss on the surface layer, middle layer, or lower layer over the entire surface. was being done. In recent years, due to demands from the market for further improvements in design and performance, there has been an increase in the number of products in which clear ink is not applied entirely, but only partially in accordance with the pattern of colored ink. In such products, it is important for improving the design and performance that there is little misalignment of the overlapping position (hereinafter also referred to as registration) between the colored ink pattern and the transparent ink pattern. However, since the transparent ink is almost transparent to visible light, it is difficult to see the clear ink in registration by an automatic registration control device or by visual observation, and it is difficult to register with a pattern of colored ink.

The printed matter and decorative sheet according to the present invention are generally multicolor printed by gravure printing, and the position (register) of each ink color of the pattern is generally performed by an automatic register control device. The automatic registration control device optically reads registration marks (hereinafter also referred to as registration marks) printed at different positions in the printing direction for each ink color, and the intervals between the registration marks are adjusted to a predetermined distance. The printing positions of the register marks are designed so that they are in register when adjusted in the printing press so that they are in register. The optical reading of the register mark is performed by irradiating the register mark with visible light and reading the intensity of the reflected light with a light receiving sensor (for example, Patent Document 1).

The registration method described above in the automatic registration control apparatus is the same for registration of transparent ink with respect to colored ink. However, as described above, since transparent ink is difficult to see in visible light, in a general automatic registration control device having a light source in the visible light range, the reflected light intensity hardly changes depending on the presence or absence of a register mark made of transparent ink. That is, since it is difficult for the mark reading means to read the registration mark formed by the transparent ink, there is a problem that the registration of the transparent ink is difficult.

To solve the above problem, for example, a method has been proposed in which an additive that emits light from a light source other than the visible light region is added to the transparent ink (Patent Document 2).

As another method, a transparent ink (second transparent ink) used for the pattern and another transparent ink (first transparent ink) different in glossiness from the second transparent ink (first transparent ink), that is, two kinds of transparent inks are used. Then, a register mark (positioning mark) layer of the second transparent ink is formed on the layer of the first transparent ink as a base, and the difference in glossiness between the two transparent inks is used to read the marks by the mark reading means. A method for reading register marks (alignment marks) with a second transparent ink has been proposed (Patent Document 3).

However, in Patent Document 2, for example, if an additive made of a fluorescent brightening agent that emits light by ultraviolet light is used, for example, when it emits light by black light, or when irradiated with visible light containing a large amount of ultraviolet light However, there is a problem that the product specifications are restricted because the appearance is different from the intended color appearance and the appearance is not intended according to the product specifications. Furthermore, in the automatic registration control device, it is necessary to change the light source and the light receiving sensor, which poses a problem that the load of the preparatory work is high.

Further, in Patent Document 3, it is necessary to add ink (first transparent ink) that is not necessary for the pattern in order to read the register marks made by the transparent ink (second transparent ink) used for the pattern. Since it is necessary to add one unit, there is a problem that the process load increases significantly.

From the above, it is an object of the present invention to reduce restrictions on product specifications and an increase in workload when registering a picture pattern formed by colored ink and a picture pattern formed by transparent ink in a printed matter containing transparent ink. Another object of the present invention is to provide a printed matter, a decorative sheet, a method for producing the printed matter, and a method for producing the decorative sheet, which have high designability.

Including the outside of the pattern, the pattern portion is printed with a pattern using all two or more different inks, and the outside of the pattern is printed with two or more register marks and a register mark base layer. and the two or more register marks are printed at two or more different positions for each of the two or more different inks, and the register mark base layer is printed in an ink different from the transparent ink among the two or more different inks. is printed so as to overlap at least a part of the register mark printed with transparent ink.

In the printed matter, the amount of ink deposited on the register mark underlayer may be smaller than the amount of ink deposited on the register mark printed with the ink used to print the register mark underlayer.

In the printed matter, the register mark base layer may be printed so as to overlap at least a part of each of the two or more register marks.

In the above printed matter, the amount of ink applied to the base layer of the register mark increases stepwise in the direction in which the two or more register marks are arranged, reaches a predetermined amount, and then decreases stepwise from the predetermined amount. good too.

(First embodiment)
A first embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. Each figure shown below is a schematic illustration, and the size, shape, decoration, etc. of each part are appropriately exaggerated or simplified for easy understanding. Configurations that are not directly related to the description are omitted as appropriate. In addition, in each figure below, the same reference numerals are assigned to the same parts, and some detailed explanations may be omitted.

FIG. 1(a) shows a printed matter 1 according to a first embodiment of the present invention.
The printed material 1 is a part (usually most) of the original fabric 10 on which the pattern 2 is printed. FIG. 1(a) is a partial conceptual diagram when the conveying direction of the printed matter 1 in the printing machine is from the bottom to the top in the vertical direction in the drawing, and the width direction of the printed matter 1 is the horizontal direction. In the printed matter 1 in FIG. 1(a), a pattern 2 is printed in most of the width direction except near both ends as an example. A portion printed with the pattern 2 in the width direction is called a pattern portion 2 . FIG. 1(a) shows the printing range of the pattern 2, that is, the pattern portion 2. As shown in FIG. In FIG. 1(a), in the width direction of the printed matter 1, the portion where the pattern 2 is not printed (not the pattern portion 2) is called the pattern outside 3, and in FIG. It is near both ends. A register mark group 29 is printed on a part of the pattern outside 3, and FIG. 1(a) is an example in which the register mark group 29 is printed near the left end. In the following description, as described above, the conveying direction is from the bottom to the top in the vertical direction in the drawing, but there is no problem even if the conveying direction is reversed. As will be described later, the unit (order) in which the transparent ink is printed does not have to be the last unit (last), and may be any unit (order).

The pattern and the register mark group 29 are printed in the same printing process. Here, the pattern 2 printed in the pattern portion 2 is a printed pattern that makes the design of the printed matter 1 recognized as a product. Examples include wood grain patterns, stone grain patterns, cloth patterns, leather patterns, geometric patterns, letters, symbols, line drawings, various abstract patterns, packaging patterns for food packaging, and other packaging patterns. On the other hand, as what is printed on the outside of the pattern 3 (those not corresponding to the pattern 2), in addition to the register mark group 29, a chart showing the plate density of each ink (the amount of ink applied), a so-called dragonfly (mark) , characters, symbols, etc. for distinguishing products, and are mainly used for managing the printing process and for managing products after printing.

In the above example, the portion where the pattern 2 is not printed (that is, the pattern exterior 3) is only near both ends in the width direction, but is not limited to this. There may be an unprinted portion (pattern exterior 3). In such a case, after the printing process, it is conceivable to divide the same product into a plurality of products or into a plurality of different products by slitting or punching the part where the pattern 2 is not printed. Even in such a case, it is included in the printed matter 1 of the present invention regardless of whether it is before or after slitting or punching.

Below, the description of the present invention describes an example where four different inks are used, one of which is a clear ink. In other words, it is four-color printing, one of which is an example of transparent ink.

FIG. 1(b) is a partially enlarged plan view of the register mark group 29 after printing the final unit (fourth unit). As shown in FIG. 1B, the register mark group 29 includes the register mark base layer 20, the first unit register mark 21, the second unit register mark 22, the third unit register mark 23, and the fourth unit register mark 24. contains. Since the present invention relates to registering clear ink, at least one of the first unit register mark 21, second unit register mark 22, third unit register mark 23, and fourth unit register mark 24 is printed with clear ink. printed. That is, at least one of the four units related to printing is a unit that prints transparent ink. FIG. 1B shows an example in which transparent ink is used as the ink for the fourth unit.

The printed matter 1 is a printed matter 1 using two or more different inks including at least one or more transparent inks, and the printed matter 1 has a pattern portion 2 on which a pattern is printed and a pattern portion 2 on which a pattern is printed in the width direction. In the pattern part 2, a pattern using all inks of two or more different inks is printed, and in the pattern outside 3, two or more register marks and a register mark bottom and a base layer 20, wherein the two or more register marks are printed in two or more different locations for inks of two or more different inks, and the register mark base layer 20 is printed with two or more different inks. It is printed with an ink different from the transparent ink so as to overlap at least a part of the register mark printed with the transparent ink.

Description will be made in accordance with FIG. 1(b). The printed matter 1 is printed matter 1 using four types (two or more) of different inks (first unit ink 11 to fourth unit ink 14) including one type (at least one or more) of transparent ink 14. The printed matter 1 includes, in the width direction, a pattern portion 2 on which a pattern is printed and a pattern outside 3 on which no pattern is printed. The pattern portion 2 is printed with the pattern 2 using all four different inks (11 to 14). Four types (two or more) of register marks (first unit register mark 21 to fourth unit register mark 24) and a register mark base layer 20 are printed on the pattern exterior 3. Four types of register marks ( 21-24) are printed at four (2 or more) different positions for each of the four different inks (11-14). The register mark base layer 20 is a fourth unit register printed with the transparent ink 14, which is different from the transparent ink 14 (the third unit ink 13, details will be described later) among the four different inks (11 to 14). Printed so as to overlap at least part of the mark 24 (clear ink registration mark 24)

FIG. 2(a) is a partially enlarged plan view of the register mark group 29, like FIG. 1(b). In FIG. 2A, for convenience of explanation, the register mark group 29 in FIG. Therefore, the conveying direction of the printing press in FIG. 2 is from right to left in the drawing as shown. Also, the register marks (first unit register mark 21 to fourth unit register mark 24) are usually in a flat rectangular shape whose long sides are in the width direction of the printed matter 1 (vertical direction in FIG. 2(a)). However, the register mark according to the present invention is not limited to a rectangular shape, and may have a triangular shape or other shapes as another example.

FIG. 2(b) is a cross-sectional view of a portion where the register mark underlayer 20 is not included in FIG. 2(a), ie, the AA line shown in FIG. 2(a). FIG. 2(c) is a cross-sectional view of a portion including the register mark underlayer 20 in FIG. 2(a), ie, a cross-sectional view taken along line BB shown in FIG. 2(a).

FIG. 4 is a conceptual diagram showing an upper threshold SU and a lower threshold SL in processing;

FIG. 2(a) shows a register mark group 29 according to the present invention as a whole. Although the details will be described later, in FIG. 2, the AA line portion in FIG. 2(a), and FIG. 2(a), FIG. 2(c), and FIG. 2(e), which show the technique and show the portion in which the register mark underlayer 20 is included, will show the present invention.

Next, taking a gravure printing machine as an example, the printing machine and the automatic register device will be described.
First, the gravure printing machine and the printed matter 1 printed by the gravure printing machine will be described. FIG. 3 is a schematic diagram for explaining an outline of a gravure printing machine 40 (a so-called four-color machine) having four printing units as an example. Here, a four-color press will be described as an example, but if the printing press has two or more printing units (two-color press or more), registration between colors is required. The present invention can be applied regardless of the number of printing units (number of colors). Further, the number of units of the printing machine 40 does not need to match the number of printing colors, and the printing machine 40 may have the number of units equal to or greater than the number of printing colors. Also, FIG. 3 is only a schematic diagram and omits many mechanisms, many rollers, etc., which are not necessary for explanation.

In the printing machine 40 shown in FIG. 3 , the roll-shaped original fabric 10 attached to the unwinding section 41 is unwound from the unwinding section 41 to become the continuous sheet-like original fabric 10 . This continuous sheet-like material 10 is also called a web in the printing machine 40 . First, in the first unit 1U for printing the first color, the web-shaped material 10 is transferred with the first unit ink 11 from the plate cylinder 431 of the first unit, passes through the drying unit 45, and passes between the first and second units. After passing through the path length adjusting means 461, it reaches the second unit 2U for printing the second color. Similarly, in the second unit 2U, the second unit ink 12 is transferred from the plate cylinder 432 of the second unit, passes through the drying unit 45, passes through the second-to-third unit path length adjusting means 462, and passes through the third color ink. to the third unit 3U for printing.

Similarly, in the third unit 3U, the third unit ink 13 is transferred from the plate cylinder 433 of the third unit, passes through the drying unit 45, passes through the third-fourth unit path length adjusting means 463, and passes through the fourth color ink. to the fourth unit 4U for printing. In the fourth unit 4U, the fourth unit ink 14 is transferred from the printing cylinder 434 of the fourth unit, and the steps up to passing through the drying unit 45 are the same as those of the first to third units. is wound into a roll.

In the first unit 1U to the fourth unit 4U, the first unit ink 11 to the fourth unit ink 14 are transferred (that is, printed), respectively. A register mark group 29 including a first unit register mark 21 to a fourth unit register mark 24 and a register mark base layer 20 is printed on the outside 3 .

How the first to fourth unit registration marks 21 to 24 and the registration mark base layer 20 are printed and the registration mark group 29 is printed will be described with reference to FIG. FIG. 4(a) shows the appearance of a portion where the register mark group 29 is formed immediately after printing of the first unit 1U. In FIG. 4A, only the first unit registration marks 21 are printed. FIG. 4B shows the appearance of the portion where the register mark group 29 is formed immediately after printing of the second unit 2U (for example, the position where the automatic register control device second unit sensor section 512 is installed). In FIG. 4B, in addition to the first unit registration mark 21, the second unit registration mark 22 is also printed.

FIG. 4(c) shows the appearance of the portion where the register mark group 29 is formed immediately after printing of the third unit 3U (for example, the position where the automatic register control device third unit sensor section 513 is installed). In FIG. 4C, in addition to the first unit registration mark 21 and the second unit registration mark 22, the third unit registration mark 23 is also printed. Further, the register mark base layer 20 is also printed so as to overlap with about half of each of the first unit register mark 21 to the third unit register mark 23 in the long side direction. That is, in the description example according to the first embodiment of the present invention, the register mark base layer 20 is printed with the third unit ink 13 in the third unit 3U.

FIG. 4D shows the appearance of the portion where the register mark group 29 is formed immediately after printing of the fourth unit 4U (for example, the position where the automatic register control device fourth unit sensor section 514 is installed). In FIG. 4D, in addition to the first unit register mark 21, second unit register mark 22, third unit register mark 23, and register mark base layer 20, the fourth unit register mark 24 is also printed.

Regarding the registration mark group 29 in the state shown in FIG. Also in this description, an example in which the transparent ink is printed in the final unit is shown, but the printing order of each ink such as the transparent ink is arbitrary. The conveying direction may be opposite to the illustrated explanation. FIG. 2(a) is a plan view showing the register mark group 29 in the same state as in FIG. 4(d). As described above, FIG. 2(b) is a cross-sectional view of the portion of FIG. 2(a) that does not include the register mark underlayer 20, ie, the AA line shown in FIG. 2(a). FIG. 2(c) is a cross-sectional view of a portion including the register mark underlayer 20 in FIG. 2(a), ie, a cross-sectional view taken along line BB shown in FIG. 2(a).

As described above, FIG. 2(b), which is a cross-sectional view taken along the line AA in FIG. 2(a), corresponds to the prior art. In the prior art shown in FIG. 2(b), each ink (first unit ink 11 to fourth unit ink 14) forming each register mark (first unit register mark 21 to fourth unit register mark 24) is Both inks are directly formed (printed) on the surface (upper side in FIG. 2(b)) of the original fabric 10. FIG.

On the other hand, as described above, FIG. 2(c), which is a sectional view taken along line BB in FIG. 2(a), shows the present invention. In the present invention, the register mark base layer 20 is printed with an ink (one of the first unit ink 11 to the third unit ink 13) different from the fourth unit ink (transparent ink) 14. In this description of the first embodiment, the register mark base layer 20 is printed with the third unit ink 13 .

In FIG. 2(c), the first unit ink 11 and the second unit ink 12, which respectively constitute the first unit registration mark 21 and the second unit registration mark 22, are applied to the surface of the original roll 10 (see FIG. 2 ( It is printed directly on the upper side) in c).

The third unit register marks 23 and the register mark base layer 20 are printed with the third unit ink 13 in the third unit 3U. The third unit ink 13 as the register mark base layer 20 is applied not only to the front and back of the already printed first unit register mark 21 and the second unit register mark 22 (horizontal direction in FIG. 2C), but also , the first unit registration mark 21 and the second unit registration mark 22 are also printed. That is, as shown in FIG. 2(c), the third unit ink 13 is applied directly to the surface of the web 10 before and after the first unit registration mark 21 and the second unit registration mark 22. In 21, it is printed over the first unit ink 11, and in the second unit register mark 22, it is overlaid on the second unit ink 12, respectively.

Focusing on the third unit register mark 23 and its surroundings, both the third unit register mark 23 and the register mark base layer 20 printed before and after it are printed with the third unit ink 13 . Therefore, normally, there is no optical difference between the register mark base layer 20 and the third unit register marks 23, and it is difficult to optically read the third unit register marks 23. FIG.

However, in the present invention, the amount of the third unit ink 13 applied to the register mark base layer 20 and the third unit register mark 23 are made different. The difference in the build-up amount of the third unit ink 13 generally appears as a difference in the layer thickness of the third unit ink 13, and optically Appears as a difference in quantity. Specifically, the amount of ink deposited on the register mark base layer 20 is less than the amount of ink deposited on the third unit register mark 23 printed with the third unit ink 13 that printed the register mark base layer 20 . ing.

As described above, the difference in the amount of ink applied generally appears as a difference in the thickness of the ink layer. In FIG. 2C, the layer thickness of the third unit ink 13 is thick in the third unit register mark 23 and thin in the register mark base layer 20 . In gravure printing, the amount of ink applied can be changed by either or both of the engraving density (cell density) and engraving depth (cell depth) of the plate cylinder. That is, in areas where a large amount of ink is desired, the engraving depth of the plate cylinder should be deepened or the engraving density should be increased. By lowering , it is possible to change the heaping amount of the same ink, that is, the layer thickness in general.

Further, as described above, the difference in the amount of ink applied also appears in the difference in the amount of light received by the automatic register control device sensor section 51 . The third unit ink 13 is colored ink, and colored ink generally absorbs (a part of) visible light. Lowered by colored ink. The greater the amount of colored ink applied, the more visible light is absorbed, so the amount of light received by the sensor section 51 of the automatic register control device is further reduced.

The portion of the third unit register mark 23 where the amount of the third unit ink 13 applied is larger than that of the register mark base layer 20 (thick layer thickness) is darker than the portion of the register mark base layer 20 in FIG. 2(a). Observed. Further, in FIG. 2(e), which conceptually shows the amount of light received by the sensor section 51 of the automatic register control device, as indicated by the amount of light received signal 523 in the third unit register mark, the third The received light amount signal 52 is significantly reduced at the unit registration mark 23 portion. For this significant decrease in the amount of received light, the third unit register marks 23 printed with the same ink (third unit ink 13) as the register mark base layer 20 should be detected by the automatic register control device sensor section 51. is possible.

As described above, the register mark base layer 20 for improving the detectability of the transparent ink 14 is printed with the third unit ink 13, which is one of the inks (11 to 13) for printing the pattern. There is no need to add a separate ink and unit for printing it to improve the detectability of the clear ink 14 . Therefore, the process load hardly increases.

A fourth unit registration mark (transparent ink registration mark) 24 is printed with the fourth unit ink (transparent ink) 14 in the fourth unit 4U. In the portion where the fourth unit register marks 24 are printed, the register mark base layer 20 has already been printed with the third unit ink 13. Therefore, as shown in FIG. 2(c), the fourth unit register marks 24 are It is printed so as to overlap the register mark base layer 20 .

In FIG. 2(e), which conceptually shows the amount of light received by the sensor section 51 of the automatic register control device, the fourth unit register mark 24 portion receives light as indicated by the light receiving amount signal 524 at the fourth unit register mark. The quantity signal 52 has increased significantly. As described above, with normal colored ink, the amount of received light decreases due to the registration marks (21 to 23), whereas the amount of received light increases at the portion of the fourth unit register mark 24 printed with the transparent ink 14. ing. Since it is "transparent", it seems that the amount of received light hardly changes. It is considered that the amount of received light increases significantly at the unit registration mark 24 portion.

In view of the above, even if the fourth unit register marks 24 are directly printed on the surface of the original fabric 10 without the register mark base layer 20, the amount of light received increases due to the luster of the fourth unit register marks 24. seems likely to be detected. However, when the register mark underlayer 20 does not exist, as indicated by 524 in FIG. This is less than the 524 copies of the .

In the conventional example, that is, when the register mark base layer 20 does not exist, the surface of the original fabric 10 is usually bright (for example, white), so it reflects visible light well, so the received light amount (Fig. 2 (d ), the flat portion of the received light amount signal 52 in ) is originally large. Even if the amount of received light increases due to the luster of the fourth unit register marks 24, the effect of the increased amount of received light is small. Therefore, as indicated by 524 in FIG. 2D, the upper threshold value SU is not reached, ie, it is difficult to detect the fourth unit register mark 24 .

On the other hand, when the register mark base layer 20 is present as in the present invention, the register mark base layer 20 is printed with colored ink as described above, so that there is not much reflection of visible light. The base layer 20 portion has a small amount of received light (a flat portion of the received light amount signal 52 in FIG. 2(e)). On the other hand, the fourth unit registration mark 24 is glossy and reflects visible light well. While the fourth unit register marks 24 printed on the register mark underlayer 20 reflect visible light well, the register mark underlayer 20 before and after the fourth unit register mark underlayer 20 reflects less light. A large difference occurs in the amount of reflected light (that is, the amount of received light) between the fourth unit registration mark 24 and the fourth unit register mark 24 . Due to this large difference (524 portion in FIG. 2(e)), the upper threshold value SU is exceeded, that is, the fourth unit register mark 24 can be detected.

In the description of the first embodiment, the first to third unit inks 11 to 13 are colored inks different from each other, and the fourth unit ink 14 is an example of transparent ink. When the printed material uses transparent ink and is used for decorative sheets, etc., after printing a colored pattern with colored ink, it is possible to print a transparent ink on top of the colored pattern in order to further enhance the design. many. That is, the transparent ink is often printed in the final unit among the units used.

However, the invention is not limited to cases where clear ink is printed in the final unit. The gist of the present invention is that when a register mark is printed directly on a raw material with transparent ink, even if the automatic register control device cannot detect the register mark with transparent ink, it is possible to print the register mark with transparent ink so that it overlaps with the register mark with transparent ink. By printing the register mark base layer 20, the register mark with transparent ink can be detected by an automatic register control device, and the register mark base layer 20 is printed with colored ink used for printing the pattern. is. From this point of view, the received light amount signal 52 of the automatic register control device is different between the place where only the register mark base layer 20 is printed and the place where the register mark with transparent ink and the register mark base layer 20 are printed in an overlapping manner. As long as the register marks made of transparent ink can be detected by a significant change, even if the registration marks made of transparent ink are printed first and then the registration mark base layer 20 is printed on top of it. I do not care. That is, the unit (order) in which the transparent ink is printed does not have to be the final unit (last), and may be any unit (order).

In view of the above, the unit that prints the transparent ink is not limited to the final unit and may be any unit. But it will be good. However, in either case, the amount of light received by the automatic register control device varies depending on the location where only the registration mark base layer 20 is printed and the location where the registration mark with transparent ink and the registration mark base layer 20 are superimposed and printed. A significant change in the signal 52 should allow the detection of clear ink register marks. This is because otherwise the effect of the present application cannot be obtained.

Next, the outline of the automatic registration control device 50 will be described with reference to FIGS. 2 and 3. FIG. The present invention relates to color registration in the conveying direction of the printed material 1 (raw sheet 10), and the automatic registration control device 50 described here also automatically controls color registration in the conveying direction.

The automatic register control device 50 detects the conveying amount detection means (not shown) for detecting the conveying amount of the printed material 1 (original sheet 10) and each register mark (first unit register mark 21 to fourth unit register mark 24). Based on signals from the automatic register control device sensor section 51, the conveying amount detection means, and the automatic register control device sensor section 51, the misregister amount in the conveying direction is calculated, and the movement amount of the path length adjusting means 46 is calculated from the misregister amount. It has a controller (not shown) that calculates and outputs a corresponding signal to the path length adjusting means 46, and a path length adjusting means 46 that changes the length of the transport path between units.

A rotary encoder is often used as the conveying amount detection means, and although the length of the conveying path corresponding to one pulse varies depending on the circumferential length of the plate cylinder, it can be accurately obtained from the circumferential length of the plate cylinder. For example, it is approximately 0.01 mm. If each register mark (first unit register mark 21 to fourth unit register mark 24) is accurately registered in the transport direction, the interval between adjacent register marks is a predetermined length (for example, 20.00 mm). It is designed and arranged to

The automatic register control device sensor section 51 is installed immediately after printing of each unit, and the automatic register control device second unit sensor section 512 to the automatic register control device fourth unit sensor section are installed in the second unit 2U to the fourth unit 4U. 514 are installed respectively. In the unit that prints the first color, there is no object to be registered and there is no need to read the registration marks. Therefore, in FIG. However, it does not matter if it is installed. Each automatic register control device sensor section 51 has a light projecting section and a light receiving section. The light-projecting part is arranged in the width direction so as to irradiate visible light onto the position where the register mark group 29 of the printed material 1 (original fabric 10) is printed, and the light-receiving part emits light emitted from the light-emitting part It is arranged at a position where it can receive the light reflected (or transmitted) at the position where the register mark group 29 of the printed matter 1 (original 10) is formed.

The light receiving portion of each automatic register control device sensor portion 51 monitors the amount of light received, for example, for each pulse of the conveying amount detecting means (preferably a rotary encoder). Then, when the first unit register mark 21 to fourth unit register mark 24 pass through the automatic register control device sensor section 51, the amount of received light is determined for each register mark (first unit register mark 21 to fourth unit register mark 24). changes. The position of each register mark can be known from the change in the amount of received light. Specifically, for example, 0.01 mm/pulse, if the predetermined design spacing of the register marks is 20 mm, adjacent register marks should be detected every 2000 pulses (=20/0.01). However, if there were actually 2016 pulses, then the following unit is out of register with respect to the preceding unit by 16 pulses, that is, by 0.16 mm. In other words, the transport distance between units is longer by 0.16 mm I understand.

The path length adjusting means 46 changes the length of the transport path between adjacent units, and is usually a roller whose shaft is movable as indicated by 461 to 463 in FIG. According to the above specific example, in order to shorten the length of the conveying path between the units by 0.16 mm, if the first-second unit path length adjusting means 461 moves downward by 0.08 mm in FIG. good. In the above example, based on the schematic diagram of FIG. 3, the length of the transport path is changed by 2.0 times the moving distance of the 1-2 unit path length adjusting means 461, but the 1-2 unit path length The relationship between the movement distance of the adjustment means 461 and the amount of change in the length of the conveying path is grasped and set in advance.

A method for detecting the position of each register mark from a change in the amount of light received in the sensor section 51 of the automatic register control device will be described with reference to FIG. As described above, FIG. 2(d) shows the amount of light received by the automatic register control device fourth unit sensor section 514 in the portion where the register mark base layer 20 is not included in FIG. 2(a), that is, the line AA. FIG. 5 is a conceptual diagram showing a signal 52, an upper threshold SU in thresholding, and a lower threshold SL; In the received light amount signal 52 in FIG. 2(d), the upward direction in FIG. 2(d) is the direction in which the received light amount increases, and the distance in the horizontal axis direction is the same between FIG. 2(a) and FIG. 2(d). I am letting

Registration of the second unit ink 12 with respect to the first unit ink 11 is performed by reading information of the first unit registration mark 21 and the second unit registration mark 22 by the second unit sensor section 512 of the automatic registration control device in the second unit 2U. based on Immediately after the printing of the second unit 2U, the register mark base layer 20 printed by the third unit 3U, the third unit register mark 23, and the fourth unit register mark 24 printed by the fourth unit 4U are still printed. It has not been. Therefore, since the register mark base layer 20 to be printed by the third unit 3U has not yet been printed, the received light amount signal in the second unit sensor section 512 of the automatic register control device is the received light amount signal shown in FIG. 2(d). In 52, the received light amount signal 523 portion at the third unit register mark and the received light amount signal 524 portion at the fourth unit register mark correspond to the signals flattened by eliminating the detection signals.

2(d), the received light amount signal 52 before the arrival of the first unit registration mark 21 is the amount of reflected light from the surface of the original web 10 and is constant (see FIG. 2(d) 521 part to the left). Then, when the first unit registration mark 21 passes through, the light reception amount signal 52 decreases due to the first unit registration mark 21 printed on the web 10 (the light reception amount signal 521 at the first unit registration mark in FIG. 2(d) part), and when it passes by, the amount of received light returns to a steady state (the part between 521 and 522 in FIG. 2(d)). Similarly, when the second unit registration mark 22 passes by, the received light amount signal 52 decreases due to the second unit register mark 22 printed on the web 10 (the received light amount signal at the second unit register mark in FIG. 2(d) 522), and when it passes by, the amount of received light returns to a steady state (the portion between 522 and 523 in FIG. 2(d)).

In FIG. 2D, the received light amount signal 521 portion at the first unit register mark and the received light amount signal 522 portion at the second unit register mark both fall below the lower threshold value SL. The unit registration marks 22 can be detected together, and the second unit ink 12 can be registered with the first unit ink 11 based on that information.

Next, registration of the third unit ink 13 with respect to the second unit ink 12 is performed by the second unit registration mark 22 and the third unit registration mark 23 by the automatic registration control device third unit sensor section 513 in the third unit 3U. based on the read information. In this description of the first embodiment, the register mark base layer 20 is printed with the third unit ink 13 in the third unit 3U. In order to explain the difference between the present invention and the prior art, both the prior art in which the register mark underlayer 20 does not exist and the present invention in which the register mark underlayer 20 exists will be described below.

First, a conventional technique in which the register mark base layer 20 does not exist will be described. Since the amount of light received signal from the third unit sensor section 513 of the automatic register control device does not print the register mark base layer 20, the amount of light received at the fourth unit register mark is For the signal 524 portion, it corresponds to a flattened signal that eliminates the detected signal.

In FIG. 2(d), both the received light amount signal 522 portion of the second unit register mark 22 and the received light amount signal 523 portion of the third unit register mark 23 are below the lower threshold value SL. The third unit register marks 23 can be detected together, and the third unit ink 13 can be registered with the second unit ink 12 based on that information. That is, it is possible to register the third unit ink 13 with respect to the second unit ink 12 even in the conventional technique in which the register mark base layer 20 does not exist.

Next, the present invention in which the register mark underlayer 20 is present will be described. Since the received light amount signal in the automatic register control device third unit sensor section 513 is for printing the register mark base layer 20, the received light amount signal 52 shown in FIG. For the signal 524 portion, it corresponds to a flattened signal that eliminates the detected signal.

In FIG. 2(e), both the received light amount signal 522 portion of the second unit register mark and the received light amount signal 523 portion of the third unit register mark are below the lower threshold value SL. The unit register marks 23 can be detected together, and the third unit ink 13 can be registered with the second unit ink 12 based on that information. That is, even in the present invention in which the register mark base layer 20 exists, it is possible to register the third unit ink 13 with respect to the second unit ink 12 .

Next, registration of the fourth unit ink 14 with respect to the third unit ink 13 is performed by the third unit registration mark 23 and the fourth unit registration mark 24 by the automatic registration control device fourth unit sensor section 514 in the fourth unit 4U. based on the read information. Here, the fourth unit ink 14 is transparent ink 14 .

First, a conventional technique in which the register mark base layer 20 does not exist will be described. Since the register mark base layer 20 is not printed, the received light amount signal in the fourth unit sensor section 514 of the automatic register control device is the received light amount signal 52 shown in FIG. 2(d).

In FIG. 2(d), the received light amount signal 524 portion of the fourth unit registration mark only slightly protrudes from the signals before and after it, and does not exceed the upper threshold value SU. Therefore, the fourth unit register mark cannot be detected, and the fourth unit ink 14 cannot be registered with the third unit ink 13 . That is, the clear ink 14 cannot be registered in the prior art in which the register mark underlayer 20 is not present.

Next, the present invention in which the register mark underlayer 20 is present will be described. Since the register mark base layer 20 is printed, the received light amount signal in the fourth unit sensor section 514 of the automatic register control device is the received light amount signal 52 shown in FIG. 2(e).

In FIG. 2(e), the received light amount signal 524 portion of the fourth unit register mark 24 exceeds the upper threshold value SU because the register mark base layer 20 is also printed thereon, and the fourth unit register mark 24 can be detected. The reason why the fourth unit register mark 24 is easier to detect when the register mark base layer 20 is printed on the fourth unit register mark 24 portion and before and after the fourth unit register mark 24 is as described above. As described in registration of the third unit ink 13 with respect to the second unit ink 12, the third unit register mark 23 can be detected even in the mode in which the register mark base layer 20 is printed.

In the present invention, both the third unit register mark 23 and the fourth unit register mark 24 can be detected, and based on this information, the register of the fourth unit ink 14 can be adjusted to the third unit ink 13. can. In other words, with respect to the registration of the transparent ink 14, the conventional technique in which the register mark underlayer 20 is not printed cannot achieve register, whereas the present invention in which the register mark underlayer 20 is printed cannot be registered. can.

In FIGS. 2(d) and 2(e), the received light amount signal 52 is simplified and expressed using a straight line. , the ideal signals as shown in FIGS. 2(d) and 2(e) cannot be obtained. Therefore, the received light amount signal 52 is normally smoothed to reduce noise. Further, regarding the detection of each of the registration marks 21 to 24, there is no simple upper and lower threshold processing for the received light amount signal 52 as shown in FIGS. 2(d) and 2(e). From the viewpoint of detecting a rapid and significant change in the quantity signal 52, threshold processing may be performed on the waveform (signal) by primary differentiation or secondary differentiation. Further, the registration marks 21 to 24 may be detected by other signal processing methods other than the above, as long as they are processed to detect a rapid and significant change in the amount of received light signal 52 .

As described above, according to the present invention, even when printing includes clear ink, the automatic register control device 50 can be used to match the register of the clear ink with the register of the colored ink. Therefore, the work load can be significantly reduced compared to the case of performing registration visually.

Further, in the present invention, since it is possible to detect the registration mark 24 of the transparent ink 14 with visible light, when using the automatic registration control device 50, for example, visible light is switched to light containing ultraviolet light. It is not necessary to switch the light source. Also from this point, the work load can be reduced. In addition, when the automatic register control device 50 is equipped with an automatic gain control function, the sensitivity setting of the sensor is not necessary, so it can be used almost fully automatically. can be significantly reduced.

Further, in the present invention, when the automatic register control device 50 detects the transparent ink 14, it is not necessary to add an additive to the transparent ink so that the sensor can easily read the ink. Therefore, for example, if an additive that emits light by ultraviolet light is used, for example, if it emits light by black light, or if it is irradiated with visible light that contains a lot of ultraviolet light, the appearance of the intended color may differ. , there is no problem that the product specification is restricted due to unintended appearance from the product specification. Therefore, it is possible to deal with a wide range of designs including transparent ink without restricting product specifications.

Furthermore, in the present invention, the register mark base layer 20 is printed with ink necessary for printing the pattern 2 . Therefore, there is no need to add a new ink to facilitate the detection of the transparent ink 14, that is, there is no need to add a printing unit, and detection of the transparent ink becomes possible without increasing the process load. It has the effect of Also, the register mark (third unit register mark 23) printed with the ink (the third unit ink 13 in the above description) for printing the register mark base layer 20 can be read without any problem. Therefore, registration control by the automatic registration control device 50 is possible for all inks including the transparent ink 14 .

In view of the problems and effects of the present invention, if the registration mark base layer 20 is printed so as to overlap at least a part of the registration mark 24 with the transparent ink 14, other registration marks (other than the transparent ink registration mark 24) ( 21 to 23). In this case, it is necessary to be able to read the register marks that are not printed so that the register mark base layer 20 partially overlaps them without the register mark base layer 20 being present. For example, it is a mode as shown in FIG. 6(a) or FIG. 7(c), which will be described later.

In the register mark group 29 according to the first embodiment, the register mark base layer 20 is printed so as to overlap at least a part of each of the register marks (21 to 24). Specifically, in FIG. 2(a) or FIG. 4(d) showing the register mark group 29, the register mark base layer 20 is printed only in the lower half of each figure, and is printed in the upper half. not The register mark base layer 20 printed on the lower half is printed for all the register marks (21 to 24) so as to overlap the lower half (part of) of each register mark (21 to 24). ing.

In the case of such a register mark group 29, the reading target position of the register mark group 29 in the automatic register control device sensor section 51 of the automatic register control device 50 is set to the portion where the register mark base layer 20 is printed (each of the above At the printing site, it is possible to select whether the registration mark base layer 20 is not printed (lower half in the figure) or the part where the register mark base layer 20 is not printed (upper half in each figure). Therefore, while confirming the detection state of the automatic register control device 50, the part where the register mark base layer 20 is not printed can be easily changed to the part where the register mark base layer 20 is printed (or vice versa). Regarding the readability of the transparent ink 14, whether or not it is better to apply the register mark base layer 20 depends on the type of the substrate 10, the type and properties of the transparent ink 14, or the printing of the register mark base layer 20. Since it depends on the color of the ink to be selected and the amount of ink applied, it is safer to be able to handle either of them.

In addition, if the registration mark underlayer 20 is printed only on a part of each of the register marks (21 to 24) in this way, the register mark underlayer 20 is not printed on each of the register marks (21 to 24). In the portion (the upper half in each figure above), a single solid color of each ink (11 to 14) is printed. Therefore, the solid printing color of each ink can be confirmed even in the register mark group 29 portion.

However, without being limited to the above, for example, when it is clear that the present invention should be applied, in the register mark group 29 of the present invention, as shown in FIG. It may be printed so as to overlap all portions of all register marks (21-24). In this case, the setting position accuracy in the width direction of the reading position in the automatic register control device sensor section 51 of the automatic register control device 50 is relaxed, that is, the position of the automatic register control device sensor section 51 in the width direction can be easily set. can do.

Examples of paper substrates for the raw material 10 related to the printed matter 1 of the present invention include kraft paper, titanium paper, linter paper, resin-impregnated paper, thin paper, Japanese paper, and the like. The fiber base material is composed of fiber base material composed of inorganic fibers such as glass fiber, alumina fiber, silica fiber, carbon fiber, etc., and organic fiber of various synthetic resins such as polyester resin, acrylic resin, polyethylene resin, polypropylene resin. fiber substrates, and substrates such as composites thereof. Moreover, the fiber base material may be a nonwoven fabric or a woven fabric.

In addition, when the material of the base material is a resin, it may be colored with a known coloring agent.
Also, the thickness of the original fabric 10 depends on the type of the original fabric 10, but is generally 10 μm or more and 200 μm or less. When the thickness is less than 10 μm and when it exceeds 200 μm, it is not preferable because it becomes difficult to perform good printing, such as difficulty in accurate conveyance in a printing machine. Titanium paper having a thickness of 80 μm can be given as an example of the original fabric 10 .

The colored inks (first unit ink 11 to third unit ink 13) for the printed matter 1 of the present invention are obtained by dissolving (or dispersing) a known coloring agent (dye or pigment) together with a resin in a solvent (or dispersion medium). can be obtained. Examples of colorants include inorganic pigments, organic pigments, metal powder pigments, pearl luster pigments, fluorescent pigments, and luminous pigments. For example, inorganic pigments include carbon black, titanium white, zinc oxide, red iron oxide, Prussian blue, cadmium red, etc. Organic pigments include azo pigments, lake pigments, anthraquinone pigments, quinacridone pigments, phthalocyanine pigments, and isoindolinone pigments. , dioxazine pigments and the like, metal powder pigments such as aluminum powder and bronze powder, and pearl luster pigments such as titanium oxide-coated mica and bismuth oxide chloride. These colorants may be used alone or in combination of two or more, or may be used together with fillers such as silica, extender pigments such as organic beads, neutralizers, surfactants, and the like.

Resins used for colored inks (first unit ink 11 to third unit ink 13) include hydrophilic treated polyester-based urethane resins, as well as polyester, polyacrylate, polyvinyl acetate, polybutadiene, polyvinyl chloride, and chlorinated resins. Polypropylene, polyethylene, polystyrene, polystyrene-acrylate copolymers, rosin derivatives, alcohol adducts of styrene-maleic anhydride copolymers, and cellulose resins can also be used in combination. Specifically, for example, as water-soluble synthetic resins, polyacrylamide-based resins, poly(meth)acrylic acid-based resins, polyethylene oxide-based resins, poly N-vinylpyrrolidone-based resins, water-soluble polyester-based resins, water-soluble polyamide-based resins, Resins, water-soluble amino resins, water-soluble phenolic resins, etc., and water-soluble natural polymers such as polynucleotides, polypeptides, polysaccharides, etc. can be used. In addition, for example, natural rubber, synthetic rubber, polyvinyl acetate resin, (meth)acrylic resin, polyvinyl chloride resin, polyurethane-polyacrylic resin, etc. modified or mixtures of the above natural rubbers, etc. Resin can also be used. The above resins may be used alone or in combination of two or more. It is preferable to add a cross-linking agent, a polymerization initiator, or a polymerization accelerator to the above resins to improve coating film strength and durability. Among the above resins, acrylic resins are preferred.

Further, the thickness of the colored inks (first unit ink 11 to third unit ink 13) is usually 0.1 μm or more and 50 μm or less. be. If the thickness exceeds 30 μm, it takes a long time to dry, resulting in poor productivity, and the poor shape stability of the ink after printing raises concerns about blocking. On the other hand, when the thickness is less than 0.1 μm, stable printing becomes difficult, and fading, ink dropout, poor transfer, and the like become a concern.

As the transparent ink 14 related to the printed matter 1 of the present invention, one having a form in which a coloring agent is not added to the material of the colored ink can be mentioned. That is, as the transparent ink 14, in addition to hydrophilic polyester-based urethane resin, polyester, polyacrylate, polyvinyl acetate, polybutadiene, polyvinyl chloride, chlorinated polypropylene, polyethylene, polystyrene, polystyrene-acrylate copolymer, rosin derivative , alcohol adducts of styrene-maleic anhydride copolymers, cellulose resins, and the like can also be used in combination. Specifically, for example, as water-soluble synthetic resins, polyacrylamide-based resins, poly(meth)acrylic acid-based resins, polyethylene oxide-based resins, poly N-vinylpyrrolidone-based resins, water-soluble polyester-based resins, water-soluble polyamide-based resins, Resins, water-soluble amino resins, water-soluble phenolic resins, etc., and water-soluble natural polymers such as polynucleotides, polypeptides, polysaccharides, etc. can be used. In addition, for example, natural rubber, synthetic rubber, polyvinyl acetate resin, (meth)acrylic resin, polyvinyl chloride resin, polyurethane-polyacrylic resin, etc. modified or mixtures of the above natural rubbers, etc. Resin can also be used. The above resins may be used alone or in combination of two or more. It is preferable to add a cross-linking agent, a polymerization initiator, or a polymerization accelerator to the above resins to improve coating film strength and durability. Among the above resins, acrylic resins are preferred.

Alternatively, a thermosetting resin, which is a polymer polymerized by heating, may be used. Preferred thermosetting resins include melamine resins, urea resins, melamine-urea resins, guanamine resins, diallyl phthalate resins, polyester resins, phenol resins, epoxy resins, aminoalkyd resins, silicone resins and polysiloxane resins.
Alternatively, an energy-curable resin that is cured by ultraviolet rays or electron beams may be used.

Among them, dipentaerythritol such as dipentaerythritol tetra (meth) acrylate, dipentaerythritol penta (meth) acrylate, dipentaerythritol hexa (meth) acrylate, etc. from the viewpoint of obtaining a higher texture design and better surface properties A system polymerizable monomer is preferable, dipentaerythritol penta(meth)acrylate and dipentaerythritol hexa(meth)acrylate are more preferable, and dipentaerythritol penta(meth)acrylate and dipentaerythritol hexa(meth)acrylate are still more preferable. Polymerizable oligomers include urethane (meth)acrylate oligomers, epoxy (meth)acrylate oligomers, polyester (meth)acrylate oligomers, polyether (meth)acrylate oligomers, polycarbonate (meth)acrylate oligomers, acrylic (meth)acrylate oligomers, poly caprolactone urethane (meth)acrylate oligomer, polycaprolactone diol urethane (meth)acrylate, and the like.

The thickness of the transparent ink 14 depends on the type of the transparent ink 14, but is approximately 0.1 μm or more and 50 μm or less. If the thickness is less than 0.1 μm, stable printing becomes difficult, and fading, ink dropout, transfer failure, and the like become a concern. In addition, it becomes difficult to obtain a tactile unevenness effect. On the other hand, if it exceeds 50 μm, it takes time to dry, the productivity deteriorates, and the shape stability of the ink after printing is deteriorated, and blocking becomes a concern.

As an example of the transparent ink 14, 60 parts by mass of an ionizing radiation-curable monomer, 0.6 parts by mass of reactive silicone, and 40 parts by mass of methyl ethyl ketone are stirred with a stirrer at 2000 rpm for 1 hour. An example of printing at 10 μm can be given.

(Second embodiment)
A second embodiment of the present invention will be described below with reference to FIG. The second embodiment differs from the first embodiment in the position where the register mark base layer 20 is printed and the distribution of the amount of ink applied. That is, in the first embodiment, in the register mark group 29, the register mark base layer 20 is printed so as to overlap at least a part of each of all the register marks (21 to 24). On the other hand, in the second embodiment, in the register mark group 29, the amount of ink applied to the register mark base layer 20 is increased stepwise in the direction (printing direction) in which the register marks (21 to 24) are arranged. A predetermined amount of filling is reached, and the amount of filling is gradually decreased from the predetermined amount of filling. Here, the predetermined heaping amount is the heaping amount that maximizes the ink heaping amount of the register mark base layer 20 in the direction in which the register marks (21 to 24) are arranged. In the example of FIG. 6(a), the density of the register mark base layer 20 increases stepwise so as to partially overlap only the transparent ink register mark 24 by the transparent ink 14, and then decreases step by step. is printed as

FIG. 6(c) is a cross-sectional view of a portion including the register mark underlayer 20 in FIG. 6(a), that is, taken along line DD shown in FIG. 6(a). FIG. 2(e) shows the received light amount signal 52, the upper threshold value SU in the threshold processing, and the lower threshold value SL by the automatic register control device fourth unit sensor section 514 in the DD line portion in FIG. 2(a). It is a conceptual diagram showing. Also, for comparison, FIG. FIG. 6D shows the received light amount signal 52 and the like from the fourth unit sensor section 514 of the automatic register control device.

As shown in FIG. 6C, the amount of ink applied to the register mark base layer 20 is increased stepwise in the direction (printing direction) in which the register marks (21 to 24) are arranged before and after the transparent ink register mark 24. It increases to a predetermined amount of filling, and then decreases stepwise from the predetermined amount of filling. With respect to the direction (printing direction) in which the register marks (21 to 24) are arranged, the transparent ink register mark 24 is arranged near the predetermined amount of ink buildup (maximum buildup amount). That is, the transparent ink register mark 24 is superimposed and printed in the vicinity of the register mark base layer 20 where the amount of ink applied is the maximum.

Regarding FIG. 6E showing the amount of light received by the mark reading means (automatic register control device sensor section 51) in the second embodiment, FIG. ) will be explained. Since the register mark base layer 20 is printed in the third unit 3U, registration up to the second unit 2U is the same as in the first embodiment. The presence or absence of the register mark base layer 20 before and after the third unit register mark 23 in the third unit 3U differs between the first embodiment and the second embodiment.

That is, before and after the third unit register mark 23, the register mark base layer 20 is printed in the first embodiment, but the register mark base layer 20 is not printed in the second embodiment. there is Regarding the detection of the third unit register mark 23 , the register mark base layer 20 printed with the third unit ink 13 which is the same ink as the third unit register mark 23 is not printed before and after the third unit register mark 23 . The second embodiment is considered easier to detect and requires no further explanation.

Next, detection of the fourth unit registration mark 24 will be described. As shown in FIG. 6C, as the third unit register mark 23 approaches the fourth unit register mark 24, the amount of ink applied to the register mark base layer 20 increases, and after the fourth unit register mark 24, the fourth unit register mark 24 is reached. As the distance from the unit register mark 24 increases, the amount of ink buildup decreases. Since the amount of ink applied is considered to be approximately proportional to the amount of light absorption as described above, the received light amount signal 52 gradually increases from the third unit registration mark 23 to the fourth unit registration mark 24 as shown in FIG. 6(e). to At the fourth unit registration mark 24, the amount of light received significantly increases due to the luster of the transparent ink 14, as indicated by the 524 portion. After the fourth unit registration mark 24, the received light amount signal 52 gradually increases as the distance from the fourth unit registration mark 24 increases.

The amount of ink applied to the register mark base layer 20 changes stepwise. As a result, since the change in the amount of received light signal 52 is gradual in the portion where the amount of received light signal 52 gradually decreases or increases linearly, the stepwise change in the amount of ink buildup is erroneously detected as a register mark. never Conceptually, as shown on the left and right of the portion of the amount of received light signal 524 in the fourth unit registration mark in FIG. , the upper threshold SU, and the lower threshold SL also gradually decrease and increase. Although the above explanation may not be accurate from the point of view of the actual arithmetic processing of the automatic register control device 50, only the rapid change is detected without detecting the gradual change of the received light amount signal 52, in other words, the plane view This is an explanation of the fact that processing is performed to detect only clear contours at the above densities.

In the second embodiment, it is possible to avoid erroneous detection of the outline of the start or end of the register mark underlayer 20 as a register mark. In the first embodiment, in order to avoid the above-described erroneous detection, the start and end portions of the register mark underlayer 20 are arranged at positions sufficiently distant from the register marks (21 to 24), and the start portion and It is preferable to set the register mark base layer 20 sufficiently long in the printing direction so that the end portion is out of the detection range of the automatic register control device sensor section 51 . Alternatively, it is preferred that the register mark underlayer 20 is printed all around the plate cylinder so that the beginning and ending portions of the register mark underlayer 20 are not present. On the other hand, in the second embodiment, it is not necessary to set the register mark base layer 20 sufficiently long in the printing direction. At the same time, the clear ink registration mark 24 can be stably detected.

In the above example, with respect to the direction (printing direction) in which the register marks (21 to 24) are arranged, the transparent ink register mark 24 is arranged in the vicinity where the amount of ink applied reaches a predetermined amount (maximum amount). was However, the present invention is not limited to this, and instead of the vicinity where the ink fill amount reaches a predetermined fill amount (maximum fill amount), for example, an area near the middle where the ink fill amount increases or decreases in stages (predetermined fill amount) The transparent ink registration mark 24 may be arranged near the half fill amount. If the light receiving amount signal 52 in the automatic registration control device fourth unit sensor section 514 significantly increases in the transparent ink registration mark 24 portion due to the action of the registration mark base layer 20, it is consistent with the gist of the present invention and can be detected. is possible.

(Modification 1)
A modification of the second embodiment will be described below. In Modification 1, as shown in FIG. 7A and FIG. The amount of ink applied to the register mark base layer 20 increases stepwise in the direction (printing direction) in which the register marks (21 to 24) are arranged to reach a predetermined amount, and from the first unit register mark 21 portion to the second unit. Up to the 4-unit register mark 24 portion, a predetermined fill amount is maintained, and the ink fill amount from the 4th unit register mark 24 portion to its downstream portion is in the direction (printing direction) in which the register marks (21 to 24) are arranged. gradually decreased to

In the first modification, in the first embodiment, the amount of ink buildup at the start portion of the register mark base layer 20 is increased stepwise to bring it closer to the first unit register mark 21, and at the end portion of the register mark base layer 20, It can also be considered that the amount of ink applied is gradually reduced to bring the fourth unit registration mark 24 closer. Further, in Modification 1, in the upstream portion of the first unit register mark 21 and the downstream portion of the fourth unit register mark 24, the amount of ink buildup increases stepwise near both the register marks (21, 24). The declining part is arranged. However, the present invention is not limited to this, and a portion where the amount of ink build-up increases or decreases stepwise may be arranged at a position distant from both register marks (21, 24) to some extent.

Also in Modification 1, it is possible to avoid erroneous detection of the outline of the start or end of the register mark underlayer 20 as a register mark. Therefore, the length of the register mark base layer 20 in the printing direction can be shortened as compared with the first embodiment, so that the printing cylinder production load and ink consumption can be reduced.

In the first embodiment, as described above, the start and end portions of the register mark base layer 20 are set sufficiently away from the register marks (21 to 24) in the printing direction so as not to be erroneously detected as register marks. It is

(Modification 2)
Next, modification 2 will be described. In Modification 2, as shown in FIG. 7(c) and FIG. 7(d) which is a sectional view taken along line FF, has no register mark underlayer 20 . Then, from the second unit register mark 22 portion to the third unit register mark 23 portion, the amount of ink applied to the register mark base layer 20 increases stepwise in the direction (printing direction) in which the register marks (21 to 24) are arranged. From the third unit register mark 23 portion to the fourth unit register mark 24 portion, the predetermined fill amount is maintained, and the ink fill amount is maintained from the fourth unit register mark 24 portion to the downstream portion thereof. It decreases stepwise in the direction (printing direction) in which the register marks (21 to 24) are arranged.

Also in Modification 2, it is possible to avoid erroneous detection of the contours of the start and end portions of the register mark underlayer 20 as register marks. Since the length of the register mark base layer 20 in the printing direction can be further shortened compared to Modification 1, it is possible to reduce the printing cylinder production load and ink consumption. However, compared with the second embodiment, the length of the register mark base layer 20 in the printing direction is longer. What should be exemplified throughout the first embodiment, second embodiment, modified example 1, and modified example 2 is that the register mark base layer 20 is printed so as to overlap at least a part of the transparent ink register mark 24, and the register mark underlayer 20 is printed so as to avoid misdetection of its start and end portions as register marks.

As described in each of the above examples, the printed matter according to the present invention is preferably printed by gravure printing. In the case of gravure printing, it is possible to directly print a special color ink by adjusting the thickness instead of combining halftone dots of the basic colors in the pattern. This is because gradation expression is possible, that is, it is possible to print a pattern having a high degree of designability. Further, the present invention assumes the use of transparent ink, and this is because a pattern using transparent ink is usually printed by gravure printing.

That is, the decorative sheet according to the present invention is a decorative sheet including the printed matter 1 according to the present invention. For example, in order to improve durability and workability, the printed matter 1 according to the present invention is laminated with another base material to form a decorative sheet. Alternatively, the printed matter 1 according to the present invention may be used as a decorative sheet by removing the pattern outside 3 where no pattern is printed by slitting, etc., leaving only the pattern portion 2 where the pattern is printed. Of course, the lamination and the slits may be combined to form a decorative sheet.

Since the decorative sheet uses the printed matter according to the present invention, there is no need to add an additive or the like to the transparent ink to improve the detectability of the register mark. Therefore, the product specifications of the decorative sheet are not restricted. In addition, there is no need to change the light source and the light receiving sensor in the automatic register control device in order to cope with additives, etc., and the workload does not increase. Further, since the register mark base layer 20 for improving the detectability of the transparent ink 14 is printed with the inks (11 to 13) for printing the pattern, another ink is used to improve the detectability of the transparent ink 14. , and no need to add a unit to print it. Therefore, the process load hardly increases.

That is, although there is almost no increase in the above-mentioned product specification restrictions and the above-mentioned work load and process load, it is possible to match the register of the transparent ink and the register of the pattern printed with the colored ink, resulting in a misalignment of the two. It is possible to provide a decorative sheet having high designability without any defects.

A pattern using ink is printed, and two or more register marks (21 to 24) and a register mark base layer 20 are printed on the outside of the pattern 3, and two or more register marks (21 to 24) are printed. 24) is printed at two or more different positions for each of two or more different inks (11 to 14), and the register mark base layer 20 is printed with clear ink among the two or more different inks (11 to 14). Inks (11 to 13) different from 14 are printed so as to overlap at least a portion of the register marks 24 printed with clear ink 14 .

In the printing machine 40 that prints the printed matter 1, the mutual registration of two or more different inks (11 to 14) in the conveying direction is controlled by an automatic registration control device 50. FIG. The automatic register control device 50 includes transport distance detection means for detecting the transport distance of the printed matter 1 in the printing machine 40, and mark reading means (automatic register control device sensor section 51) for optically reading the register marks (21 to 24). , control means and path length adjustment means 46 . The control means calculates the amount of misregistration in the conveying direction from the signals from the conveying distance detecting means and the mark reading means (automatic register control device sensor section 51), and moves the path length adjusting means 46 based on the misregistration amount. and outputs a signal corresponding to the amount of movement to the path length adjusting means 46. Based on the signal, the path length adjusting means 46 adjusts the intervals between the registration marks (21 to 24) to a predetermined interval. The register in the conveying direction is controlled by changing the length of the conveying path so that .
The details of the operation of the automatic registration control device 50 have been described in the description of the printed matter 1 above, and are omitted here.

In the method for producing the printed matter 1, since it is not necessary to add an additive or the like to the transparent ink to improve the detectability of the register mark, the additive or the like limits the product specifications. There is no In addition, there is no need to change the light source and the light receiving sensor in the automatic register control device in order to cope with additives, etc., and the workload does not increase. Further, since the register mark base layer 20 for improving the detectability of the transparent ink 14 is printed with the inks (11 to 13) for printing the pattern, another ink is used to improve the detectability of the transparent ink 14. , and no need to add a unit to print it. Therefore, the process load hardly increases.

That is, although there is almost no increase in the above-mentioned product specification restrictions and the above-mentioned work load and process load, it is possible to match the register of the transparent ink and the register of the pattern printed with the colored ink, resulting in a misalignment of the two. It is possible to provide a method for manufacturing a printed matter 1 having high designability without any defects.

[Method for manufacturing decorative sheet]
Next, a method for manufacturing the decorative sheet according to the present invention will be described. A method for manufacturing a decorative sheet according to the present invention is a method for manufacturing a decorative sheet including the above method for manufacturing a printed matter. As an example, a case where the decorative sheet according to the present invention is a laminate of the printed matter 1 of the present invention and a vinyl chloride film as a substrate will be described. By thermally laminating a vinyl chloride film via an adhesive to the surface opposite to the surface on which the pattern is printed of the printed matter 1 produced by the method for producing printed matter (raw side surface), A decorative sheet according to the present invention can be produced.

The printed matter 1 and the decorative sheet according to the present invention use transparent ink, and the picture pattern formed by the colored ink and the picture pattern formed by the transparent ink are in register. The tactile ruggedness of the transparent ink, the visual ruggedness due to the matching of the pattern of the colored ink and the ruggedness of the transparent ink, or the difference in gloss, etc., express high designability.

Therefore, since the effect of the transparent ink is more likely to be obtained when the transparent ink 14 is present on the outermost surface, it is conceivable to thermally laminate a vinyl chloride film via an adhesive on the side of the printed matter 1 on which the pattern is printed. Hateful. However, if the printed matter 1 is produced by the production method according to the present invention, a decorative sheet produced by thermally laminating a vinyl chloride film via an adhesive to the side of the printed matter 1 on which the pattern is printed. is also included in the present invention.

The slitting of the printed material 1 is as described above, and even if the decorative sheet is obtained by laminating the printed material 1 after slitting, even if the laminated decorative sheet is slit. , are included in the manufacturing method of the decorative sheet of the present invention. Further, in the method for manufacturing the decorative sheet described above, the same effect as in the method for manufacturing the printed matter 1 can be obtained.

(Examples and Comparative Examples)
EXAMPLES Examples and comparative examples according to the present invention will be described below. Using 3 different colored inks (1st unit ink to 3rd unit ink) and 1 type of transparent ink for 8 different raw fabrics (raw fabric A to raw fabric H), the same as the present invention made a print. When creating a printed matter, regarding the printing of the register mark base layer, three types of ink (1st unit ink to 3rd unit ink) and the amount of ink fill when printing the register mark with the ink In the case of 100%, the fill amount was changed to 20%, 40%, and 60%, and seven types of register mark base layers with different combinations of ink types and fill amounts were printed. In addition, as a conventional example, a printed material was also prepared without printing the register mark base layer.

Raw fabric A to raw fabric H are 80 μm thick titanium paper (manufactured by KJ Specialty Paper Co., Ltd., product numbers (A to H in order), KSH-801P, PM-62P, PM-67P, PM-28P, PM- 42P, PM-52P, KW-801P, PM-77P) were used.
For the first to third unit inks, Ode PF manufactured by DIC Graphics Corporation was used.
The transparent ink is composed of 60 parts by mass of an ionizing radiation-curable monomer (Aronix M400, manufactured by Toa Kasei Kogyo Co., Ltd.), 0.6 parts by mass of reactive silicone (X-22-164B, manufactured by Shin-Etsu Chemical Co., Ltd.), and methyl ethyl ketone. (Maruzen Petrochemical Co., Ltd.) 40 parts by mass were stirred at 2000 rpm for 1 hour with a stirrer (process homogenizer PH91, manufactured by SMT Co., Ltd.).

For each of the above 64 types, which is a combination of 8 types of original fabric and 8 types of registration mark base layer (7 types + none), the portion where only the registration mark base layer is printed, the registration mark base layer and the transparent ink registration mark The difference (V) in the output voltage (V) of the automatic register control device sensor unit was calculated for the portion where the was printed. That is, it is the amount of signal variation (V) due to the transparent ink registration mark. MR5500 manufactured by Nireco Corporation was used as an automatic register control device. Table 1 shows the results.

In Table 1, when the difference in output voltage is 1.7 V or more, it can be determined that noise can be separated as a significant signal in the clear ink registration mark portion, that is, the clear ink registration mark can be detected. As a conceptual explanation, in the conceptual diagram of the change in the amount of light received by the sensor unit of the automatic register control device in FIG. is a received light amount signal of -1.7V.

Referring to Table 1, even if the printing conditions for the registration mark base layer are the same, the amount of signal fluctuation (V) due to the transparent ink registration mark varies considerably depending on the type of substrate, that is, the color and surface condition of the surface of the substrate. , that is, there is a large change in numerical values in the vertical direction of Table 1. From this, it can be seen that even the portion where the register mark base layer is printed is greatly affected by the original fabric. Also, even with the same raw material, there is a difference in the signal fluctuation amount (V) due to the transparent ink register mark depending on the printing conditions of the register mark base layer, that is, there is a difference in the numerical value in the horizontal direction in Table 1 I understand.

In the conventional example in which the register mark base layer is not printed, among the 8 types of raw materials, 4 types exceed 1.7V and 4 types fall below 1.7V. In other words, half of the types of original fabrics according to Examples and Comparative Examples had voltages below 1.7 V, suggesting that some kind of contrivance is necessary for reading register marks of transparent ink. On the other hand, among the seven types of register mark underlayers according to the present invention, in the printing with the first unit ink with a fill amount of 40% and the third unit ink with a fill amount of 20%, all eight types of original fabrics It exceeds 1.7V. From this, it can be understood that the present invention is useful for reading transparent ink registration marks, and furthermore, it suggests that the registration mark underlayer can be printed under the same conditions on a wide variety of substrates. It was confirmed that the invention has high versatility.

The printed matter, the decorative sheet, the method for producing the printed matter, and the method for producing the decorative sheet according to the present invention have been described above with reference to the embodiments. However, the invention is not limited to the above embodiments. The above embodiment is an example, and the technical idea described in the claims of the present invention, which has substantially the same configuration and has the same effect, is the present invention in any case. It is included in the technical scope of the invention.

The printed matter and the decorative sheet according to the present invention have high designability and performance because the picture pattern of the transparent ink and the picture pattern of the colored ink are in register. Such printed materials and decorative sheets can be suitably used as interior materials such as wallpaper for interiors of houses and buildings, and interiors of transportation equipment such as automobiles and railway vehicles.
