Abstract

PURPOSE:To obtain an elongated printed matter by using an existing printing plate cylinder without using any printing plate cylinder that has a large circumference, by a method wherein a plurality of kinds of pattern components are combined to form a composite pattern while setting repeating periods of the pattern components to be shorter than that of the composite pattern. CONSTITUTION:Patterns (a), (b) are printed on a rolled paper 10 by the first printing plate cylinder 8 comprising a printing plate surface 6 in which an effective printing plate surface region 1 is sectioned alternately into non-printing regions 2, 4 and printing regions 3, 5 along the circumferential surface of a form cylinder 7 at regular pitch in the circumferential direction and in which the first group of patterns (a), (b) are provided sequentially in the printing regions 3, 5. Then, other patterns are printed on blank parts of the thus printed paper by using the second printing plate 18 comprising a printing plate surface 16 in which an effective printing plate surface region is sectioned into non-printing regions 11, 13, 15 and printing regions 10, 12, 14 along the circumferential surface of a form cylinder 17 having a circumference different from that of the form cylinder 7 for the first printing plate cylinder 8 at regular pitch in the circumferential direction and in which the second group of patterns A, B, C are provided sequentially in the printing regions. Accordingly, printing is conducted with a long period of repetition of patterns.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a long printed matter having a pattern with a long repeating period, in which pattern components with a short repeating period are combined.

(Prior art) Decorative paper with a wood grain pattern has conventionally been printed using a printing cylinder with a circumference of tg'tomw or less, but printed matter formed in this way has a short repetition pitch of the pattern. It had the disadvantage of being slow to change.

Therefore, in recent years, the repeating pitch of the patterns is long, for example! There is an increasing trend in the market for the supply of long printed matter such as repeat 2700wg or Jqoo.

However, depending on the demand, 270014N or 3
In order to supply 900 m long printed matter, it is necessary to newly install a large printing machine with a large circumference printing plate, and considering the current situation where the demand for the long printed matter is limited, the above printing machine It is extremely difficult to amortize equipment costs.

Also, the circumference of the printing plate in the existing plate making method for printing decorative paper is /
Many of them are around 100 m x 6 shaku) (and from the perspective of using these printing plates, it is not a good idea to use the above-mentioned large printing presses.

The present invention has been made for the purpose of solving the above-mentioned drawbacks of the prior art, and the long printed matter of the present invention has a composite pattern formed by combining two or more types of pattern components on the surface of the paper,
Moreover, the repetition period of any of the pattern components is shorter than the repetition period of the composite pattern.

(Structure) FIG. 1 is a plan view showing an embodiment of the long printed matter of the present invention, in which A, a, and B are printed on the surface of the paper.

Each pattern is arranged and printed in the order of b, C, a, A, b, B, a, C, b, and as shown in Figure 1, from A at the left end to b near the right end is l. It is a repeat, that is, a repeating period.

FIG. 2 is a plan view showing a state in which only the first pattern component, that is, the patterns AIB and C indicated by uppercase English letters, are printed on paper from among the patterns shown in FIG. , as shown in FIG. 2, the repetition period is from A at the left end to C near the center.

Similarly to Figure 2, Figure 3 shows the pattern components of the elements shown in Figure 1, i.e., a and b shown in lowercase English letters.
FIG. 3 is a plan view showing a state in which only the patterns , , and , are printed, and as shown in FIG. 3, the portion consisting of one each of a and b has a repeating period.

In the examples shown in Figures 1 to 3 above, the pitch of each pattern, that is, the dimension in the length direction of the repetition period, are all equal for simplicity, so the repetition period in Figure 1 is the same for each pattern. It is 12 times the pitch, 6 times the pitch in FIG. 2, and 9 times the pitch in FIG. Therefore, compared to the repetition period of the composite pattern shown in FIG. 1 in which the pattern components shown in FIGS. 2 and 3 are combined.

The repetition period of the pattern component shown in FIG. 2 is 2, and the repetition period of the pattern component shown in FIG. It's also short.

(Manufacturing method) A method for producing a long printed matter of the present invention will be explained next using the long printed matter of the above embodiment as an example.

and a plurality of second group patterns (A) in the printing area.
(Second printing plate unit subjected to endless plate making, in which a plate surface (16) is formed in which Bl (C) is sequentially allocated)
Using this method, printing is performed on the margins of the printed paper roll as shown in the first diagram to perform long printing with a long pattern repetition period.

If the printed material to be obtained now is a monochromatic printed material, a long printed material can be obtained by the above-described printing process.

If the next print you want to obtain is a multicolor print,
By sequentially printing each color plate according to the above-described method, a multicolor long printed matter can be obtained.

In the method of the present invention, a gravure printing method, a silk screen printing method, etc. can be applied as a printing method.

Next, the present invention will be described in detail with reference to Examples.

The effective printing surface area was applied to the foamed wallpaper winding base paper prepared by coating and gelling the colored vinyl chloride paste containing a foaming agent on the backing paper of Example ioo~. A small-diameter printing plate that is alternately divided into non-printing areas and printing areas at every lθ% in the direction, and has a plate surface in which a first group of multicolor abstract pattern plates are sequentially allocated to the printing area. The effective plate surface area is divided into a non-printing area and a printing area alternately at 10% intervals in the circumferential direction, and three second groups of multicolors are provided in the printing area. Using a large-diameter printing plate on which a printing plate with an abstract pattern is sequentially arranged, printing with the small-diameter printing plate and busy printing with the large-diameter printing plate are sequentially performed to print a long plate. Then, along the circumferential surface of the plate cylinder with a circumference tIIo'x*, the effective plate surface area is divided into a non-printing area and a printing area alternately at every 10x in the circumferential direction, and the printing area is divided into two areas. A small-diameter printing plate is formed with a printing plate in which red rice with a multicolored abstract pattern of the first group is sequentially laid out, and the effective printing plate area is 1260% along the circumference of the plate cylinder. The small-diameter printing plate is produced by using a large-diameter printing plate that is alternately divided into areas and printing areas, and has a plate surface in which three second groups of multicolored abstract pattern red rice are sequentially allocated to the printing area. Printing with the large-diameter printing plate and printing with the large-diameter printing plate are performed sequentially to print a long strip of sekihan, and then the effective plate surface area is set every 1/0% in the circumferential direction along the circumferential surface of the plate cylinder with a circumference of gqθ. A small-diameter printing plate with a plate surface that is alternately divided into a non-printing area and a printing area, and in which the first group of multicolor abstract pattern printing plates are sequentially allocated to the printing area.
The effective plate surface area is 210% in the circumferential direction along the circumferential surface of the plate cylinder.
Printing using a small-diameter printing plate using a large-diameter printing plate that is alternately divided into non-printing areas and printing areas at intervals, and in which three second groups of multicolored abstract pattern printing plates are sequentially allocated to the printing area. Then, printing was carried out sequentially using a large-diameter printing plate, and long-length printing was carried out using a matching plate, thereby printing the pattern and the pattern of the suppressed portion after foaming in multiple colors.

Furthermore, the printed surface was overcoated.

The above printing paper was foamed in an IgO-:110″C foaming furnace, and the ink pattern mixed with the inhibitor was concave!r:l
A textured foam wallpaper with a repetition period of 0% was produced.

(Effects) Since the long printed matter of the present invention has the above configuration, it is suitable for obtaining printed matter with a repetition period longer than the circumference of the plate cylinder using a printing plate with a relatively small diameter or an existing printing plate. Therefore, the long printed matter of the present invention can be effectively applied to the production of long wall materials, long ceiling materials, and long floor materials with patterns such as wood grain patterns and abstract patterns.
