Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for making a print using a rubber plate, a wood block or the like.

[Conventional technology]

Conventionally, when creating this type of print, a colored ink that is liquid at room temperature is used, and the liquid ink is applied to the convex portion formed on the plate surface of the plate material, and the image material is brought into contact with the convex portion of the plate surface. In this state, an image is formed on the image material by applying pressure to absorb the liquid ink applied to the projections of the plate surface into the image material.

[Problems to be Solved by the Invention] Such a simple print making method has a variety of drawbacks because it is a method that has not changed since 1000 years since the printing technique was developed. Although partly solved by the creator's skill, it was difficult to form a clear image at a technically immature stage.

The disadvantages are that it is difficult to equalize the thickness of the liquid ink applied to the plate surface of the plate material, and the image formed on the image material is likely to be uneven, and that the ink material absorbs ink moderately Have to,
The transfer of the liquid ink causes unevenness or bleeding, and the painting material is limited to the ink-absorbing material, and an image is hardly formed on a resin film or the like.

In view of the above-described circumstances, the present invention can produce a good print without skill, and can also easily produce a print on non-ink-absorbing painting materials such as resin films. The purpose is to make

[Means for solving the problem]

The simple print making method according to the present invention is a method of melting & / O
R softened, an ink sheet in which a solid colored ink at room temperature and a fixed thickness is provided on one side of a sheet-shaped base material at a constant temperature, which causes an adhesive force on the plate surface of the image material and the plate material in this state,
The colored ink layer is adhered to the convex portion of the plate surface by heating while being in contact with the plate surface of the plate material.Next, after the colored ink layer is cooled and solidified, the ink sheet is removed from the plate surface, and the plate surface is removed. The colored ink layer is adhered to the convex portion of the substrate, and thereafter, an image material is brought into contact with the plate surface and heated, the colored ink layer of the convex portion is adhered to the image material, and the colored ink layer is cooled and solidified. By peeling the art material,
The color ink layer is transferred to an image material.

(Operation)

When preparing a plate surface, first, an ink sheet is superimposed on the plate surface of the plate material in a state where the colored ink layer thereof is in contact with the convex portion of the plate surface, and in this state, the ink sheet is heated by a heating means such as an iron. Of the colored ink layer melts and / or softens, and the colored ink layer adheres to the projections of the plate surface.

After the colored ink layer is cooled and solidified in this state, when the ink sheet is peeled off from the plate surface, the colored ink layer of the ink sheet is transferred to the convex portion in a layered state. The amount of the transferred colored ink is substantially the same as the amount of the colored ink at the contact portion of the ink sheet, and the thickness of the colored ink in the surface direction of the ink sheet is also substantially uniform.

Next, the image material is superimposed on the plate surface of the plate material to which the colored ink layer has been transferred in a contact state, and heated by a heating means such as an iron in this state, the colored ink layer transferred to the projections of the plate surface again. Melts & / OR softens and the colored ink layer adheres to the painting material.

In this state, after the colored ink is cooled and solidified again, the image material is peeled off from the plate surface of the plate material, and transferred to the image material in a state of the color ink layer of the convex portion when it adheres to the convex portion. Thus, an image corresponding to the shape of the projection is formed on the image material.

〔The invention's effect〕

Therefore, it is necessary to use an ink sheet in which a colored ink is provided in a layer with a certain thickness on one side of a sheet-like base material, and to use the melting & / OR softening phenomenon by heat and the solidification phenomenon by cooling as described above. By synergistic with, the amount of colored ink transferred from the ink sheet to the plate surface of the plate material, and the amount of colored ink transferred from the plate surface of the plate material to the painting material can be equalized over the entirety, Even if the force for pressing the image material against the plate surface of the plate material slightly changes, the ink transfer amount does not change.

Therefore, as compared with the conventional method using a colored ink that is liquid at normal temperature, a clear image can always be formed reliably and well on the image material without soiling the fingers of the operator.

In addition, since the melting and / or softening phenomenon by heat and the cooling and solidifying phenomenon are utilized as described above, a desired image can be easily formed even on an ink non-absorbable painting material such as a resin film. , The restrictions on art supplies are reduced by that much,
The use of prints can be expanded.
