Description

[Detailed description of the invention] The present invention relates to a method for producing a long printed matter.

Traditionally, printed materials such as woodgrain patterns have been printed using plate cylinders with a circumference of 1890 mm or less, but printed materials formed in this way have the disadvantage that the pattern repeats at a short pitch, making them difficult to change. .

Therefore, in recent years, there has been an increasing demand in the market for the supply of long printed matter with a long pattern repeat pitch, for example, one repeat of 2700 mm or 3900 mm.

However, depending on those demands, 2700mm or
In order to supply long printed matter of 3900 mm, it is necessary to install a new printing machine that can handle printing plates with a large circumference, and considering the current situation where the demand for the long printed matter is limited, the printing machine is It is thought that amortizing equipment costs is extremely difficult.

As a result of research to develop a method for obtaining long printed matter using existing equipment, the inventor of the present invention discovered a method in which a long picture is printed diagonally on a web of paper, and then the web is cut diagonally. For example, they discovered that it is possible to obtain long printed matter that is longer than the circumference of an existing printing press, and based on this knowledge, they completed the present invention.

That is, the gist of the present invention is to provide a long area within a large rectangular area defined by sides in the vertical direction that are multiple times the circumferential length of the plate cylinder and sides in the left and right directions that are equivalent to the length in the left and right direction of the printing plate. A strip-shaped basic pattern is arranged with its longitudinal direction diagonal to the vertical side of the large area, and the basic pattern is parallel to the left and right sides of the large area at intervals of the vertical length of the printing plate. A plurality of divided patterns are divided by dividing lines to form positives, and the positives are pasted onto a mount so that they are positioned at horizontal positions corresponding to the horizontal positions occupied by each divided pattern within the large area. a process of producing a pasted positive for 10 minutes, a process of making an endless printing plate by making a plate using the pasted positive, and a process of printing using the printing plate so that the basic pattern is aligned in the longitudinal direction of the web. A step of producing a rolled printed matter in which a large number of prints are printed diagonally relative to the rolled paper, and a process of cutting the rolled printed matter in a diagonal direction with respect to the longitudinal direction of the rolled paper through the margin between the basic pattern printing areas. This method of producing a long printed matter is characterized by the step of obtaining a large number of long printed matter that are longer than the circumference of the printing cylinder on which the basic picture is printed.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

As shown in the first figure, a large rectangular area (the first
In the illustrated example, a long strip-shaped basic pattern 6 is arranged in an area (3 times the area of the printing plate) 1 with its longitudinal direction oriented diagonally to the vertical side 2 of the large area 1. is divided by dividing lines 4 and 5 parallel to the left and right sides of the large area 1 at intervals of the length in the vertical direction of the printing plate to form positives of a plurality of divided patterns 6a, 6b, and 6c, as shown in the second figure. , divided pattern 6a, 6
The positives 7, 8, and 9 of b and 6c are pasted on the mount 10 so as to be located in the horizontal position corresponding to the horizontal position occupied by each divided pattern 6a, 6b, and 6c in the large area 1, and one plate is made. A pasting positive 11 is prepared.

Next, plate making is performed using the produced pasting positive 11 to produce an endless printing plate (not shown). Then, by printing using the printing plate, a rolled printed matter 12 in which a large number of basic patterns 6 are printed diagonally with respect to the longitudinal direction of the rolled paper is obtained.

Next, as shown in the fourth diagram, the paper is cut diagonally to the longitudinal direction of the web through the margin between the basic pattern printing areas to obtain a large number of long strips longer than the circumference of the plate cylinder, on which the basic pattern is printed. A printed matter 13 is obtained.

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

Next, in the manufacturing method of the present invention, the rolled printed matter is cut by (i) placing a knife diagonally with respect to the rolled printed matter, and intermittently feeding the rolled printed matter toward the knife to cut it; (ii) die roll; (iii) Cutting by hand along the cut line.

Next, the present invention will be specifically explained with reference to Examples.

Example: Using a linear plate with a circumference of 1240 mm and a handle width of 1350 mm, a wood grain pattern with an angle of 60° was created with a thickness of
Printing was carried out using a gravure method on a 1400 mm wide vinyl chloride clear film containing 20 parts of 0.2 mm plasticizer.

Further, the above printing film was heat-pressed with a 1400mm wide colored vinyl chloride film with a thickness of 0.23mm and 28 parts of plasticizer so that the printing ink was between the film layers, and then a predetermined position of this two-layer vinyl chloride film was held at an angle of 60°. It was cut at 110 mm in width and 4000 mm in length.

A two-layer vinyl chloride film with a width of 320 mm and a length of 4000 mm was cut into pieces with a thickness of 15 mm, a width of 320 mm, and a length of 4000 mm.
A long edge deck was manufactured by hand gluing it onto mm plywood using EVA adhesive.

This edge deck does not have the same pattern repeated in the length direction, and the finished flooring material has a design similar to that of the edge deck made of natural wood in terms of pattern composition.

As detailed above, according to the method of the present invention,
By using existing equipment as is, it is possible to obtain long printed matter that is longer than the circumference of the existing printing press.
Furthermore, according to the method of the present invention, it is possible to create abstract patterns with a wide variety of patterns without repeating patterns, which was previously impossible.

The method 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.
