Description

Description: TECHNICAL FIELD The present invention relates to a register mark seal attached to a master paper or the like in order to accurately perform multicolor printing in the case of multicolor printing.

[Conventional technology]

Conventionally, register marks are often attached to predetermined places such as master paper by black-printing, and the accuracy is strictly required for the black-printing. Therefore, especially when the number of the master-paper is large. It took a lot of time and effort.

On the other hand, instead of the above direct ink-jetting, a method is known in which a required unit portion is cut out from an adhesive transparent tape on which a register mark is continuously printed in advance and the portion is attached to a predetermined portion such as a master paper. However, it is difficult to finely adjust the sticking position before sticking, and there is a problem in sticking workability.

In addition, Japanese Patent Publications No. 52-16404, No. 52-10401 and No. 53-6482 are provided with a cut line for extraction on the mount and the display piece is placed outside the cut line. Disclosed is a sticking means for sticking at least a part of the sticking piece on the sticking piece, which makes it possible to easily align the sticking piece by sliding the mount onto the sticking object. However, in this method, the display piece is pressed onto the adherend through the see-through window created by the removal of the section of the cut-out section line, while the entire mount is peeled from the periphery of the display piece and pulled up upward. Was required, and this left a problem in workability for attachment.

[Problems to be Solved by the Invention]

An object of the present invention is to provide a register mark seal which can be accurately and efficiently attached with a register mark at a predetermined position on a master copy sheet or the like.

[Technical means for solving problems]

The register mark seal according to the present invention comprises one adhesive transparent sheet having a register mark and one release sheet coated on the adhesive surface of the adhesive transparent sheet, wherein the release sheet has a loop shape. Alternatively, a substantially U-shaped dividing line separates the island-shaped or peninsular inner release sheet corresponding to at least the core portion of the register mark and the outer release sheet surrounding the inner release sheet so as to be individually peelable, and the outer release sheet. Is characterized in that it is further divided into individual strips.

In the above, the shape of the register mark seal itself, the kind of the register mark, etc. are not limited. The outer release sheet is divided into individual peelable sheets for improving the peeling workability, but the inner release sheet may be divided as necessary. The register mark may be drawn on the adhesive transparent sheet by printing, photoengraving or other method, and it does not matter whether the adhesive surface is on the register mark drawing surface or on the opposite surface, but the former In the case of (1), the interval between the register mark and the adherend such as the master paper is shortened, so that more accurate fine adjustment of the sticking position is possible. Further, in the above description, the core portion of the register mark means a portion of the register mark which can be centered by superimposing it on the sticking position mark which is previously attached to a predetermined portion such as the master paper. The pressure-sensitive adhesive transparent sheet or release sheet in the present invention broadly includes sheets and films, and there is no particular limitation on the thickness, form, material, or the like.

Next, the present invention will be described based on the drawings. 1 and 2 are plan views of an embodiment of the present invention, which are mainly register mark seals having register marks indicating the center line, which are arranged at the top and bottom of the stencil sheet and at the center portions on the left and right.
Further, FIG. 3 is an enlarged sectional view of an embodiment of the present invention.

In the above drawings, the adhesive surface 3 of the adhesive transparent sheet 2 provided with the register mark 1 has an inner release sheet 5 corresponding to at least the core 4 of the register mark 1 and an outer release sheet around the inner release sheet 5. 6 and 6 are separated and separated by a loop-shaped or substantially U-shaped dividing line 7 and are attached.

In the case shown in FIG. 1, the loop-shaped dividing line 7
The island-shaped inner release sheet 5 and the hollow outer release sheet 6 around the inner release sheet 5 are separated from each other, and the hollow outer release sheet 6 is ring-opened and bisected at two locations. Thus, the subdivision line 8 is engraved.

Further, in the structure shown in FIG. 2, the penetrating inner release sheet 5 and the substantially concave outer release sheet 6 around the inner release sheet 5 are separated from each other by a substantially U-shaped dividing line 7. Further, a small dividing line 8 is engraved on the substantially concave outer release sheet 6 so as to divide it into two.

In the above-mentioned examples, regarding the mode of division by the division line 7 and the small division line 8 or the shape of the island-shaped or peninsular-shaped inner release sheet 5 formed by division,
It may be replaced with another division mode or other shape within the range in which the object of the present invention can be achieved.

[Work]

A method of using the register mark seal according to the present invention will be described with reference to the drawings.

4 (A) and (B) to (D) are a plan view and a magnified sectional view illustrating the use of the embodiment of the present invention, respectively. First, from the adhesive surface of the adhesive transparent sheet 2 to the inner release sheet (FIG. After peeling only (not shown), the same figure (A) and (B)
As shown in FIG. 5, the outer release sheet 6 is laminated on the master paper 9 which is an adherend so that only the outer release sheet 6 is in contact with the master paper 9. Then, the sticky transparent sheet 2 is transparently seen from above the sticky transparent sheet 2 so that the core portion 4 of the register mark 1 exactly overlaps the sticking position mark 10 previously put on the master paper 9. Is slid along the upper surface of the block paper 9. At this time, the inner pressure-sensitive adhesive surface 3a exposed by peeling the inner release sheet is not attached to the master paper 9 as it is because of the thickness of the outer release sheet 6 around the inner release surface. The fine adjustment work of the sticking device by the above-mentioned sliding can be performed very easily.

When the adjustment by sliding is completed, the same figure (C)
As shown in (3), the inner adhesive surface 3a is pressed and adhered onto the master paper 9. By this work, the inner adhesive surface 3a is stuck on the master paper 9 in a state where the core portion 4 of the register mark 1 is accurately overlapped on the sticking position mark 10, so that the positional deviation thereafter can be prevented. You can

Then, in the state where the inner adhesive surface 3a is adhered to the master paper 9 as described above, the outer release sheet 6 is pressed against the inner adhesive surface 3a so that they are not peeled off, and the outer release sheet 6 is divided into the small dividing lines 8.
By stepwise peeling, the exposed outer adhesive surface 3b is pressed onto the master paper 9 to be adhered, and as shown in FIG. At this time, since the outer release sheet 6 is divided into three parts by the small dividing line 8, it is not necessary to forcibly pull out the whole, and the peeling can be carried out smoothly in steps, and the inner adhesive surface 3a is pressed. However, peeling and sticking work of the outer release sheet 6 can be facilitated.

(Effect of the invention) As described above, in the register mark seal according to the present invention, the release sheet is divided into the island-shaped inner release sheet and the outer release sheet that surrounds the inner release sheet and the individual release sections,
Moreover, since the outer release sheet is further divided so that it can be peeled off individually, it can be peeled off stepwise with good workability, and the register mark can be attached accurately and with good workability at a predetermined position on the master paper.
