The films 3 may be formed of paper. The films 3 printed with the section rule equal measures 4 on the rear surface of the film 1 are peeled and removed after sticking the films atop the film 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film used for printing plate making work and plate making work.

[0002]

2. Description of the Related Art In printing work such as plate making and plate making, when a plurality of different layout materials (photograph, manuscript with mark or logo, etc.) different from each other such as photographs and characters, ruled lines and characters are pasted and pasted, A film is hung on a basic base such as a lower mount, and photographic manuscripts and typesetting letters that overlap each other are pasted on different surfaces. At that time, on the film,
Since the work is done while measuring the sticking position and horizontal, vertical, parallel, etc. of the photographic manuscript and typesetting characters, the time and labor required for the work increase as the number of sticking points increases. In addition, since it is difficult for a pencil or ink to get on the film, a guideline is marked by lightly scratching the film with a cutter knife or the like.

[0003]

DISCLOSURE OF THE INVENTION The present invention, when the layout material is pasted on a film hung on a basic base such as a block mount on which a layout material is pasted,
It is an object of the present invention to provide a film that saves time and labor for measuring dimensions such as horizontal, vertical, and parallel, enables quick, easy, and accurate work and does not hinder the subsequent plate making work.

[0004]

According to the present invention, when the layout material is pasted on the film hung on the basic base such as the underprint mount, it is possible to save the trouble of adjusting the horizontal and vertical directions twice, so that the film 1 On the lower surface, an adhesive layer 2 and a film 3 on which a guide 4 such as a grid ruled are marked are sequentially laminated. A peeling treatment layer 5 made of silicon or the like may be provided between the film 1 and the adhesive layer 2. Furthermore, the film 1 and the film 3 on which the guide lines 4 such as grid lines are marked are thermocompression bonded, vacuum adhered,
They may be integrated by a temporary adhesion state such as electrostatic adhesion, or the film 3 may be formed of paper.

After the sticking to the upper surface of the film 1 is completed as shown in FIG. 1, the film 3 on the lower surface of the film 1 marked with a guide 4 such as a grid rule is peeled and removed. Therefore, finally, only the layout material stuck to the film 1 remains on the basic base such as the underprint mount, and there is no problem in the later plate making work.

As shown in FIG. 2, the pressure-sensitive adhesive layer 2 plays a role of temporary adhesion between the film 1 and the film 3 on which the guide lines 4 such as grid lines are marked. Since the film 3 is finally peeled off and removed, a weak adhesive is preferable so that it can be easily peeled off. However, depending on the combination of the materials of the film 1 and the film 3, the film 1
The peeling force can be adjusted by subjecting the lower surface of the above to a peeling treatment with silicon or the like.

Means for adhering the film 1 and the film 3 to each other is not limited to the adhesive. For example, as shown in FIG. 3, the film 1 and the film 3 are made of thermoplastic resins having different melting points such as polyester and polyethylene, respectively. If both are heat-pressed, they will be in a temporarily bonded state. There is no risk of spontaneous peeling or misalignment due to this adhesion, and it can be peeled off smoothly with a finger. Similarly, vacuum,
Temporary adhesion by electrostatic contact is also possible.

The films 1 and 3 may be transparent or semi-transparent as long as they do not hinder the plate making work, and may be paper or synthetic resin. The guide line 4 such as a grid ruled on the film 3 may be printed or printed by a developing process, and the surface to be marked may be either the upper or lower surface of the film 3, but may be marked on both surfaces. . Film 3
Is peeled off and finally removed, so a standard color such as grid lines,
There is no limitation on density, ink composition, etc., and it can be freely selected.

The grid ruled in this specification is just one of the standard patterns. The pattern can be considered and used in addition to the grid ruled line. For example, only parallel lines can be sufficiently used as a standard for horizontal or vertical. Further, it may be an oblique ruled line used for a perspective view or the like, or an outline pattern such as a map of Japan. Further, the pattern need not occupy the entire surface of the film, but may be marked only in the central portion and other data may be marked in the peripheral margin. INDUSTRIAL APPLICABILITY The present invention can be used not only in printing block making and plate making operations, but also in various fields by changing a pattern according to the purpose of use.

[0010]

[Operation] Pasting onto a film hung on a basic base such as a block mount can be easily completed by using a guideline such as grid lines. After that, the guide lines such as grid lines are peeled off and removed, so that it is possible to move to the next plate making work without any trouble.

[0011]

[Example] FIG. 1 (a) is a copyboard on which a photographic original is pasted, and (b) is a film laid on the copyboard on which a typesetting letter is pasted using a rule such as a grid rule. State,
(C) shows a finished master after peeling and removing a guide such as a grid rule. 2A shows a plan view of an embodiment of the cover film of the present invention, and FIG. 2B shows a sectional view taken along line XX of the same embodiment. Figure 3
Shows a sectional view of another embodiment.

In FIG. 1A, the palm tree photo original 10 is a square plate and occupies approximately two-thirds of the space below the plate surface of the plate mount S. And the typesetting letter 11 of "Eternal Summer Island"
Although it is desired to paste so that the lower half of the character hangs on the photo original 10, if it is pasted as it is, the ruled line 12 for specifying the position of the photo original 10 is hidden. Since it is not possible to proceed with the subsequent plate making work, the guide lines 4 such as grid lines of the cover film 6 are applied in parallel with the plate surface of the underprint mount S. This work can be easily done by using the corners or center marks that are marked on the printing plate as a guide. Next, the upper portion of the cover film 6 on the inner side of the master block mount is fixed with the tape 13. In this way, the typesetting characters 11 can be pasted without erasing the ruled lines 12 for specifying the position of the photo original 10, and the work can be performed quickly and accurately by using the guide lines 4 such as grid rules. Thereafter, as shown in (c), the film 3 on which the guide lines 4 such as grid lines are marked is peeled off and removed, and the plate making operation is started.

In FIG. 2, the cover film 6 was constructed as follows. 75 μ polyester was used for the film 1, a normal weak pressure sensitive adhesive was used for the pressure-sensitive adhesive layer 2, and 50 μ polyester was used for the film 3. On the lower surface of the 50 μ polyester, a guide 4 such as a grid ruled in 1 mm increments is printed with blue ink by screen printing. To make it easier to see, it is easier to work if you add strength to the thickness of the line, such as medium weight every 5 mm and thick line every 1 cm. The typesetting letter 11 of "Tsunatsu no Shima" (simplified in the drawing) was cut on the edges of the letter in parallel and vertically with a ruler and a cutter, and it was pasted on the film 1 using a guideline 4 such as a grid rule [ FIG. 1B]. After that, the film 3 was gently peeled and removed from the film 1 with a finger [Fig. 1 (c)]. During the work, troubles such as the positional deviation between the film 1 and the film 3 of the cover film 6 and the generation of wrinkles did not occur.

FIG. 3 shows a mode in which the film 1 and the film 3 are adhered without using an adhesive, and the film 1 is made of 50 μ polyester and the film 3 is made of 50 μ polyethylene, and they are temporarily bonded by thermocompression bonding. . In this case as well, the work was completed in the same manner as in the above-mentioned embodiment.

[0015]

The attachment of the layout material on the film hung on the surface of the master block mount can be easily completed by the rule such as the grid ruled on the film. In addition, since the guide lines such as grid lines are peeled and removed, they have no influence on the subsequent plate making work. Therefore, a standard pattern such as a grid rule,
It is possible to freely select and utilize the color and ink components without restriction.
