Abstract

PURPOSE:To obtain the register mark seal which uses no released paper, and also, is convenient for carrying by constituting if of a first transparent film layer whose one face is an adhesive face, and a second transparent film layer of narrow width laminated to the same adhesive face side, and also, putting a register mark onto one of the surface and the reverse side of a first and a second film layers. CONSTITUTION:This register mark seal consists of a first transparent film layer 2 whose one face is an adhesive face 3, and a second transparent film layer 4 of narrow width laminated on the same adhesive face side, and also, a register mark 1 is put onto one face of the surface and the reverse side of a first and a second film layers 2, 4. The adhesive face 3 of a first film 2 floats from the paper face 5 for a block copy by a thickness portion (d) of a second film layer 4, therefore, at the time of executing an aim alignment, a fine adjustment can be executed, while sliding to the paper face 5 for a block copy. When the aim alignment is completed, the adhesive face 3 of a first film layer 2 protruded from both edge sides of a second film layer 4 is pressed against the paper face 5 for a block copy and can be stuck. In such a way, the register mark seal which uses no released paper, and can be rolled up, and is convenient for carrying is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a register mark sticker used for alignment of printing plates or original drawings, etc., in order to ensure accurate alignment of each color in multicolor printing.

(Conventional technology) Conventionally, register marks have been placed on predetermined areas of printing paper, etc. by inking, but inking is technically difficult and
It takes quite a while to become proficient.

In addition, there was a drawback that each task took time. Therefore, various methods were considered as a solution to this problem. The most sensitive method is to print register marks continuously on adhesive tape.

At the stage of use, each mark is cut out and affixed to a predetermined location on a piece of printing paper or the like while being registered.

Although this method eliminates the inconvenience of inking, it is almost impossible to finely adjust the registration before pasting.

In order to improve this point, the present inventor published Utility Model Application No. 59-4854.
f5 (Utility Application No. 57-145436) was devised. In this prior invention, the register mark is a sticker. In other words, register marks are printed continuously on an adhesive transparent sheet, the adhesive side is covered with release paper, and then each register mark is cut into a single unit of sticker. The difference is that a separation line is provided on the release paper to separate the release paper part (A) corresponding to the center part of the register mark and the surrounding part (B).

To explain this in detail with reference to Fig. 5 (1) to (3), (
As shown in 1), on the adhesive surface 23 of the adhesive transparent sheet 22 with the register mark 21 attached, there is a division cut-off line that divides it into a peeling part (A) corresponding to the center part 24 of the register mark and a peripheral part CB). There are 25. To register using this register mark sticker, do the same 1! I
As shown in (2), first, only the peeling portion (A) is peeled off, and then the peripheral portion (B) is applied to the base paper 29. There is already no release paper in the peeling area (A), so the adhesive surface 23 is exposed, but the adhesive surface is lifted from the base paper surface 29 by the thickness of the surrounding area (B), so the plate can be removed immediately. The first peripheral portion CB) can be slid on the surface of the base paper 29 without being attached to the bottom paper 29.

While sliding, look through the transparent seal to see the mark made in advance with a pencil or the like on the bottom surface of the plate, and when the mark matches the position of the register mark, press your finger from above the transparent seal in the direction of the arrow in the figure (3). When pressed, the center portion 24 of the register mark is pressed against the draft paper 29 and a register mark is attached. In this state, the release paper on the first peripheral portion (B) is peeled off and the entire seal is pasted on the printing paper surface 29. Since the seal is transparent, only the register mark 21 remains clearly on the draft paper 29. Accurate registration is possible through fine adjustment by sliding.

(Problems to be Solved by the Invention) The register mark seal according to this prior invention has a seal for each mark, so work efficiency is high, and fine adjustment by sliding is possible, so accurate registration is possible. On the other hand, it requires the effort of storing the separate stickers in a box, etc., and the effort of peeling off the release paper from the stickers.Furthermore, there is the inconvenience that the release paper sometimes remains as a huge shoulder after being peeled off. Ta.

This invention has been made in order to eliminate the above-mentioned disadvantages while taking advantage of the advantages of this prior invention.

That is, firstly, no release paper is used, which not only saves the trouble of peeling off the release paper, but also eliminates the need to use expensive release paper, which helps reduce costs.Secondly, This prevents the harmful effects of releasing small pieces of release paper as waste. Thirdly, it can be rolled up and stored like adhesive tape (eg, product name "Cellotape"), making it convenient for maintenance and portability.

(Means for Solving the Problems) In order to achieve the above object, the register mark sticker of the present invention has a first transparent film layer with an adhesive surface on one side, both extending in the same direction, and a layer laminated on the same adhesive side. a second transparent film layer having a width narrower than that of the first film layer, and a register mark is attached to one of the four surfaces of the first and second film layers in total. It is said that

In order to achieve the above object, the register mark sticker of the present invention further includes a tape-shaped first transparent film layer with one adhesive surface, and a discontinuous second film layer laminated at a predetermined interval on the adhesive surface side. two transparent film layers, and
It is characterized in that a register mark is attached to one of the four sides of the overlapping portion of the first and second film layers.

(Function) The adhesive surface of the first film layer is raised from the paper surface under the thickness separation of the second film layer, so it does not stick to the same paper immediately, and the second film layer does not touch the same paper. Therefore, when performing registration, it is possible to make fine adjustments while sliding the second film surface onto the printing paper surface. Once the registration is completed, the adhesive surface of the first film layer protruding from the edge of the second film layer can be pressed against the surface of the printing paper to adhere it.

(Example) Example (1) Continuous relatively narrow transparent synthetic resin film 2 (e.g.
One side of the polyethylene film) is used as the adhesive side 3. The adhesive surface 3, hereinafter referred to as the first film, is formed by applying an adhesive using a known method. Adhesive w3
A second transparent film 4 having a narrower width than the first film 2 is laminated on the side in the length direction. Since the second film 4 has a narrower width than the first film 2, the adhesive surface 3 protrudes toward the top of the width of the second film 4. If the amount of protrusion is too large, there is a risk that the protruding edge will sag, so it should be set so that it does not sag. If it hangs down, there is a risk that the adhesive surface will stick to the draft paper 5 as shown in FIG. 2 (2). If the thickness of the film is increased to prevent sagging, cutting will be hindered. Reference numeral 6 serves as a guideline for cutting the - register mark as one unit, and is shown as a dotted line in one drawing for convenience of explanation, but normally (including perforations to be drawn) is not performed.

Example (2) In FIG. 3 and 4W1, code 2 indicates Example (1)
In this embodiment, it is a similar continuous transparent synthetic resin film with a relatively narrow width and has an adhesive surface 3.

The shape of the second film 4 is different from that in Example (1).

Here, the second film is in a discontinuous form with regular intervals. Although the cutting line 6 is assumed between the adjacent second film layers, this is for the sake of convenience for simple explanation of the drawings, similar to Example (1). As shown in FIG. 4, the cross section cut along the cutting line 6 shows that the adhesive surface 3 of the first film layer protrudes as a protruding edge from the image side of the second film layer, as in Example (1). There is. A register mark 1 is attached to the overlapping portion where the first and second film layers overlap.

In the illustrated embodiments (1) and (2), the register mark 1 is attached to the surface of the first film 2, but the position of the register mark 1 can be determined by appropriately selecting at least four positions. That is, you only need to select one of the front and back sides of the first film 2, the front and back sides of the second film 4, and the planning surface.Since both films 2 and 4 are transparent, the register mark can be placed anywhere in the above list. The same is true even if there is.

Another way to add register marks is by printing.

Known methods such as development and printing can be used. In the case of development and baking, it is decided whether to apply a diazo photosensitive resin to the film layer or to use a diazo photosensitive resin film as the film itself, taking into consideration cost, workability, etc.

To use this register mark sticker for registration, the sticker is cut into register marks along the cutting line 6 to form a seal.Then, the 4 sides of the second film are applied to the draft paper 5 for each sticker. Since the W films 2 and 4 are transparent, the markings on the draft paper side can be clearly seen. Also,
Since there is a gap (d) equal to the thickness of the second film 4 between the adhesive surface 8 and the paper surface 5, the two do not stick together immediately. Paper 5
The entire seal can be slid by contact with the surface.

While sliding, finely adjust the register marks and the markings on the surface of the printing paper. Once the registration is achieved, press the protruding edge of the adhesive surface 3 onto the printing paper 5 to adhere it and place the first and second films on the printing plate. Fix it to the lower paper 5. FIG. 2 (2) shows the process in which the protruding edge is pressed against the draft paper 5. This situation also occurs when the first film 2 is thin and hangs down on the draft paper 5. Become.

Cutting is done by register mark unit in the width direction of the strawberry film using a knife, scissors, or other commonly used means.If the register mark is used as a roll in the form of adhesive tape,
It is convenient if the roll holds a special disposable blade like the one attached to adhesive tape.

(Effect of the invention) Since no release paper is used, there is no need to remove the release paper.
In addition, the shoulder of the release paper does not come out and expensive release paper is not used, which helps reduce costs.

Fine adjustment of registration can be performed while sliding the second film surface on the surface of the printing paper, so that more accurate registration can be achieved. Since there is no release paper, the total thickness of the first film and the second film combined can be thin, and it can be used by winding it up on a core like an adhesive tape, making it convenient to carry.
