JPS6034847A - Printing stamp by thermocompression transfer using foaming ink - Google Patents

Abstract

PURPOSE:To improve the operability as a printing stamp by a method wherein a sheet of transfer paper formed with foaming ink is placed on a printing block and heated under pressure to be thermally compressed, and with the foaming ink made to foam and protrude, a character, a figure or the like is transferred in a protuberant state onto a transfer object. CONSTITUTION:When transfer is cnducted, transfer paper 4 is peeled off released paper 5 and placed, with a thermally-compressed film 1 down, on a transfer object 6. This transfer object 6 may be formed of an iron plate, an Al plate, a synthetic resin plate or any other material, although a material which is not denatured or deteriorated at the foaming temperature of the foaming ink 2 is preferable therefor. When the transfer paper 4 is heated, with a prescribed pressurizing action, from above by a desired heating and pressurizing means, such as an iron 7, for instance, the thermally-compressed film 1 is bonded by heat on the transfer object 6 and put in the fixed state 1', while the foaming ink 2 on the film 1 foams to be protuberant, and thus a character 3 is transferred as a character 3 being protuberant three-dimentionally. Consequently, a character 3' is formed on the surface of the transfer object 6 as if a character printed on said surface foams to be protuberant. The character 3' thus formed is employed as a stamping member for printing.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stamp made by thermocompression transfer using foamable ink.

In conventional rubber stamps, the impression part was formed of natural rubber, etc., and the flat stamp main body was processed by engraving or the like.

However, conventional rubber stamps are time-consuming and expensive to process.

This invention was made in view of these problems, and uses foaming ink to draw characters, figures, etc. to form a transfer paper, and then places the transfer paper on an object to be transferred, that is, a stamp stand. The stamp is then placed under pressure and heated to be thermocompression-bonded, and foamed ink is applied to form a raised shape, thereby providing a stamp in which the characters, figures, etc. are transferred onto the object in a raised state.

Next, one embodiment of the present invention will be described based on the drawings.

Reference numeral 1 denotes a thermocompression bondable film, which is molded into a film shape from thermoplastic synthetic resin such as polyethylene, etc., and can be thermocompression bonded to another object at a predetermined temperature and pressure.

2 is a foaming ink that foams and rises at a predetermined heating temperature. Using this foaming ink 2, characters 3 are drawn on the thermocompression adhesive film 1 by a desired printing means (not shown), and then the transfer paper is printed. Get 4. Further, a release paper 5 is attached to the transfer paper 4 to facilitate handling of the transfer paper 4.

During the transfer, the transfer paper 4 is peeled off from the release paper 5 and placed on the transfer target 6 with the thermocompression adhesive film 1 facing downward. The material to be transferred 6 may be made of any material such as an iron plate, an aluminum plate, a synthetic resin plate, a wooden board, or paper, cloth, or synthetic paper, but any material that does not denature or deteriorate at the foaming temperature of the foaming ink 2 may be used. shall be.

Next, by heating the transfer paper 4 with a predetermined pressing force using a desired heating and pressing means such as an iron 7, the thermocompression bonding film 1 is thermocompression bonded to the transfer target 6 and fixed to the state 1'. As a result, the foamable ink 2 on the thermocompression bonding film 1 is foamed and raised, and the characters 3 are transferred as three-dimensional raised characters 3'. Therefore, characters 3' are formed on the surface of the transfer object 6 as if the characters printed on the surface were foamed and raised. This is used as a seal impression member for stamps. Incidentally, during thermocompression bonding with the iron 7, an intervening plate 8 made of paper or other material may be interposed between the iron 7 and the transfer paper 4 to avoid sudden heating or to perform uniform heating.

As detailed above, according to the present invention, characters, figures, etc. drawn on a thermocompression adhesive film using foamable ink are transferred by pressing and heating onto a transfer target, so that It is possible to transfer and draw raised characters, figures, etc. on the surface, and the transfer operation is easy and simple, and it has the practicality of being able to be used as a stamp with good workability.
