Abstract

PURPOSE:To obtain a beautiful transferred matter without a loss in a simple manner by enabling printing and transfer thermosensitively of a desired transfer image on a prearranged base sheet with the use of printing device such as a thermosensitive transfer printer, a typewriter and a word processor. CONSTITUTION:A base sheet 10 on which a transfer image such as freely desired character or figures is printed or transferred thermosensitively using a thermosensitive printer, is taken out of the printer and used for desired instant lettering. A dry transfer sheet thus obtained 20 has a mirror image or a real image of a transfer image 21 such as desired character or figure formed on the base sheet 10. The dry transfer sheet 20 is given pressure 31 from the black in such a manner that a transfer image 21 part is opposed to an intended region of a prearranged receptor 30, and this transfer image 21 is retransferred by a pressure-sensitive transfer method. Consequently a lettering image 41 of the transfer image retransferred is formed on a prearranged region of the receptor 30, and the desired lettering receptor 40 is completed.

Description

Detailed Description of the Invention (Technical Field) The present invention relates to a method for producing a dry transfer sheet for instant lettering, and in particular a method for easily producing a dry transfer sheet having a transferred image of desired characters, figures, etc. It is related to.

(Prior art and its problems) Conventionally, dry transfer materials or sheets used for lettering, etc., transfer images or indicia of characters, figures, etc. to be transferred onto a predetermined base material. It is produced by printing using printing ink by screen printing, etc., and is peeled and transferred to any receiving surface by the action of an adhesive that is printed, sprayed, coated with a wire bar, etc. Thus, the desired instant lettering is realized (Japanese Patent Application Laid-open Nos. 49-49714 and 49-133).
No. 111, No. 51-53916, Special Publication No. 57-543
13, British Patent No. 58-50200, and specifications such as British Patent No. 954459 and British Patent No. 959670).

However, in the manufacturing method of this type of transfer material,
The implementation of this method requires a large investment of money and expenditure of time, as it requires the use of printing machines and the production of suitable printing plates, screens, and the like. .

For this reason, for consumers who do not want to invest such funds and time, it is necessary to purchase products made separately by a manufacturer and sold commercially, and for this purpose, it is necessary to transfer the desired characters, figures, etc. You don't just get the statue, you also have to buy letters and figures that you don't need, so there's a lot of waste - the cost per letter is very high, and in some cases you have to buy the letters and figures that you don't need. There are even cases where it is impossible to purchase because there are no written words. Moreover, words, phrases, sentences, etc. need to be picked up letter by letter from commercially available lettering transfer sheets and transferred while aligning, which is extremely time-consuming and difficult to layout. It was extremely difficult to achieve a beautiful finish.

On the other hand, in recent years, another method for producing dry transfer materials has been to expose a photosensitive material to an image and then develop it, thereby separating a transfer image such as a desired figure or character onto a carrier or basic sheet. A photographic method has also been proposed that leaves images in
Publications such as -7959 and British Patent No. 1079661
No. 1291960, No. 1364627, No. 1441982, etc.).

However, even in the case of this photographic method, it is necessary to expose and develop, so an exposure device and a developing device are required. It has inherent problems that require investment and time consumption. In addition, even with this photographic method, consumers cannot create desired letters and figures on their own for lettering, so they must purchase ready-made lettering transfer sheets, and therefore, it is necessary to purchase a ready-made lettering transfer sheet. However, it is inevitable that the cost per character will be high, and it is difficult to lay out words, phrases, sentences, etc., and furthermore, there are problems such as it may not be possible to obtain the desired transfer image of figures, characters, etc. Similarly, it is inherent in it.

(Object of the Invention) The present invention has been made against this background, and its object is to provide a simple method for producing a dry transfer sheet for instant lettering. In particular, by making it possible for the user to arbitrarily form a transfer image of desired characters, figures, etc. on a base sheet and easily leave a transfer sheet behind, the waste of unnecessary characters, figures, etc. can be eliminated. -The cost per character can be reduced, and users can freely layout words, phrases, sentences, figures, etc., and can also create figures, etc. that have never existed before. It's about making it possible.

(Solution Means) That is, the feature of the present invention is to manufacture a dry transfer sheet for pressure-sensitively transferring a transfer image such as a desired character or figure to a target part of a predetermined receptor. At this time, an instant method including printing and thermally transferring the transfer image selected by the printing device from an ink ribbon onto a predetermined base sheet using a printing device such as a thermal transfer type printer, typewriter, word processor, etc. A method of manufacturing a dry transfer sheet for lettering.

(Specific Configuration/Example) As described above, the present invention utilizes printing devices such as thermal transfer printers, typewriters, word processors, etc., whose production volume has increased significantly in recent years, to print a predetermined base material sheet. A desired dry transfer sheet is prepared by printing and thermally transferring a desired transfer image onto the sheet, an example of which is schematically shown in FIG.

That is, in FIG. 1, lO is a base material sheet on which a transferred image of desired characters, figures, etc. is formed, and on it,
A desired transfer image is thermally transferred as a mirror image or a real image by a thermal transfer printing device operated by a user. More specifically, based on a selection command for a transfer image such as a desired character or figure from an input device constituting a printing device such as a thermal transfer printer, typewriter, word processor, etc., The heating element 14 is made to generate heat, and as is well known, printing and thermal transfer are performed from the ink ribbon 15 onto the base sheet 10 corresponding to the heat generating portion, thereby forming a target transferred image. is formed on the base sheet lO.

Note that in order to effectively thermally transfer a target transfer image onto the base sheet 10 using such a thermal transfer type printing device, the position and shape of the heating element 14 of the head 13 and the winding of the ink ribbon 15 must be adjusted. The taking torque, head pressing pressure, head mounting angle, head energy, printing speed, etc. are adjusted as appropriate. Further, here, a thermal transfer printing device of a thermal head type is shown, which is constituted by a thermal head having a heating element 14 made up of a plurality of resistors (heating elements) that generate heat by selective energization. In addition, there is an energization type in which a conductive layer is provided on the ink ribbon 15, and a needle electrode is applied to a necessary part of the conductive layer and a current is passed intensively to cause the conductive layer in that part to generate heat and transfer is performed. A thermal transfer printing device can also be used in the same way.

By the way, as mentioned above, the desired transfer image thermally transferred onto the base sheet 10 is retransferred (sensitized) to the intended receptor (transferred object) by applying a predetermined pressure from the back side of the sheet. (pressure transfer), the surface of the base sheet 10 to be subjected to thermal transfer is in a state of good releasability, in other words, a state of poor wettability. This is desirable. The base sheet 10 with good mold releasability may be paper, metal foil,
Alternatively, in addition to using a plastic film alone as appropriate, as shown in FIG. A mold release promoting layer 12 formed thereon is preferably used.

Examples of the plastic film used here include films made of polyethylene terephthalate, polyethylene, polypropylene, nylon, polyimide, fluorine resin, vinyl chloride resin, polysulfon, polycarbonate, ABS resin, and the like.

Further, in order to facilitate positioning during subsequent pressure-sensitive transfer, the base sheet 10 is preferably transparent or semi-transparent, and in particular, a semi-transparent sheet is used so that it is easy to check whether the transferred image has been transferred. It is most preferable that the sheet has the following properties, and furthermore, it is desirable that the sheet has appropriate flexibility so that pressure can be easily applied to the transferred image during pressure-sensitive transfer.

Among these, in the present invention, in order to improve the quality of the transferred image during thermal transfer, a base sheet with high surface smoothness and few unevenness is advantageously used, especially for thermal transfer through a platen. It is desirable to use as the base sheet 10 a sheet having a thickness of 50 to 200 μm, preferably 70 to 150 μm, which can advantageously ensure the required appropriate flexibility.

The ink ribbon 15 used for thermally transferring a desired transfer image onto the base sheet 10 may be coated with a commonly used wax-based ink; It is preferable to use an ink ribbon having a two-layer structure consisting of a transferability adjusting layer and an ink layer, which further improves transferability and pressure-sensitive transferability. This transferability adjustment layer is provided as a top coat layer on the ink layer, and has better heat-sensitive adhesiveness, hardness,
It is a layer with high viscosity and cohesive force, and as a result, heat-sensitive transferability to the 10 surfaces of the base sheet with poor wettability is significantly improved. The pressure-sensitive transferred image becomes strong, and by providing pressure-sensitive adhesive properties to the ink layer, the pressure-sensitive transfer of the transferred image formed by heat-sensitive transfer to the receptor is also good. You get it.

Then, the base sheet 10, on which transfer images such as desired characters and figures are printed and thermally transferred using a thermal transfer type printing device, is taken out from such a printing device. The dry transfer sheet 20 thus obtained is used for instant lettering, and as shown in FIG. The transferred image 21 is formed as a mirror image or a real image.

In addition, as shown in FIG. 3, the dry transfer sheet 20 is arranged on the back side of the sheet so that the transferred image 21 faces the target region of a predetermined receptor (transferred object) 30. By applying pressure 31 from above and retransferring the transferred image 21 using a pressure-sensitive transfer method, the transferred image 21 is retransferred to a predetermined portion of the receptor 30, as shown in FIG. A lettering image 41 is formed, and the desired lettering receptor 40 is completed. In addition, in the dry transfer sheet 20 after the transfer image 21 is pressure-sensitively transferred to the receptor 30 in this way,
In the area where the transferred image 21 used for the pressure-sensitive transfer is placed,
Naturally, no transferred image remains.

(Effects of the Invention) As is clear from the above description, according to the present invention, a user can easily create a transferred image of desired characters, figures, etc. using a thermal transfer printer, typewriter, word processor, etc. can be created on a predetermined base material sheet, unlike conventional ready-made lettering sheets, unnecessary characters and figures are not generated at all, and therefore waste can be eliminated. The cost of lighting can be advantageously reduced, and since the layout can be made freely, various shapes can be created, and therefore beautiful and waste-free transfer objects can be easily obtained. Various excellent effects such as being able to be achieved were achieved, and the great industrial significance of the present invention can be found therein.
