[Object of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of printing on a curved surface such as a fishing rod, and more particularly to a method of making a print defect visually inconspicuous.

[0002]

BACKGROUND OF THE INVENTION One of the methods for printing on a curved surface is so-called hydraulic transfer printing. In this printing method, an activator is applied to the water-soluble thin film on which the pattern is printed to activate the pattern ink, and while this is floated on the water surface, the transfer target is pressed against the water-soluble thin film and The pattern is transferred to the transfer target by means of, for example, the color difference between the part where the pattern is transferred and the part where the background color of the transfer target is not transferred, or ink of two or more colors. When applying the pattern printed in, due to the difference between the colors created by the overlap with the background color of the transferred material,
It is possible to draw various patterns.

However, in this hydraulic transfer printing method, fine air bubbles sometimes enter between the water-soluble thin film F ₀ 'and the transferred material B', and the printing pattern is not transferred at that portion, which causes a defect. Part K '. In this case, when either the hue or the lightness of the color of the transferred material B ′ and the color of the print pattern are not similar, the transferred pattern becomes clear due to the contrast with the background color as shown in FIG. On the contrary, the defective portion K'is also conspicuous, and the commercial value of the transferred material B'is significantly reduced. However, if the hue and lightness of the color of the transferred material B ′ and the color of the print pattern are approximated as shown in FIG. 6, the defective portion is visually inconspicuous, but the transferred pattern is inconspicuous. It is easy to become sober.

[0004]

[Technical Items Attempted to Develop] The present invention has been made in view of such a background, and the defective portion is not conspicuous,
This is an attempt to develop a method for blurring a defective portion in hydraulic transfer printing that makes the transferred pattern clear.

[0005]

[Constitution of the invention]

[Means for Achieving the Object] That is, the first invention of the present application is a method for blurring a defective portion in hydraulic transfer printing, in which a water-soluble thin film in which an ink of a print pattern floats in an active state on a water surface, The transfer target made of a dark color is pressed to immerse part or all of the transfer target below the water surface, and the pattern is transferred to the transfer target by water pressure, and the water-soluble thin film is removed with water. In the printing method described above, the pattern is composed of a dark color having the same color or hue and lightness as that of the transferred material, and the activator is colored in a light color. It is a thing.

In addition to the above requirements, the transfer object is dark brown in color, the pattern is black brown in color, and the second aspect of the present invention is a method for removing defects in hydraulic transfer printing. The activator is characterized in that it is white brown.

[0007]

According to the present invention, the printing pattern is composed of the same color as that of the transferred material or a dark color having a similar hue and lightness, and the activator is colored in a light color. The defect portion, which is a dark-colored color of the transfer target, is assimilated to the color of the pattern having similar hue and lightness to that of the defect portion and is not conspicuous. Also, the transferred pattern part is a dark color, and the other transferred part is a bright color because it is covered with an activator, so the pattern clearly appears due to the contrast between the two. ..

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on the illustrated embodiments. As shown in FIG. 1, the hydraulic transfer line 1 includes a hydraulic transfer device 2, a supply conveyor 3, a connection conveyor 4, a discharge conveyor 5, and a connection conveyor 4, which are continuously arranged on the side thereof. It is provided with an automatic supply device 6 and an automatic discharge device 7 which are provided on the side of the hydraulic transfer device 2.

The hydraulic transfer device 2 includes a transfer tank 10 for containing water W, a transfer conveyer 11 above which a transfer target holding device 14 is provided at regular intervals, and a print film supply device 12. It consists of. Printing film supply device 1
Reference numeral 2 comprises an original roll 15 in which the pattern printing film F is wound in a roll shape, and a solvent tank 16 which stores an activator S for activating the ink printed on the pattern printing film F. A feed roller 17 is appropriately provided so that the pattern printing film F fed from the original roll 15 is activated by the activator S in the solvent tank 16 and then continuously supplied into the transfer tank 10. Further, the automatic supply device 6 has a plurality of gripping devices 18, and the gripping device 18 chucks the transfer target B to supply the transfer target B into the transfer tank 10 from above, and after the transfer is completed, it can be discharged. There is.

The present invention will be described below while explaining the flow of performing hydraulic transfer printing using such a hydraulic transfer line 1. The target printed by the present invention is a dark color such as black or dark brown. In the present embodiment, as an example, a dark brown fiberglass fishing rod A is transferred. The body.

First, the pattern print film F is supplied from the print film supply device 12 onto the water surface in the transfer tank 10. Here, as shown in FIG. 4, the pattern-printed film F is a water-soluble film F ₀ made of gelatin, sodium alginate, polyvinyl alcohol or the like, on which the transfer pattern P is printed. The transfer pattern P is composed of the same color as that of the fishing rod A, which is the transfer target, or a dark color whose hue and lightness are similar to each other. In this embodiment, the transfer pattern P is black brown. Black brown has a darker degree of darkness than dark brown.

Since the pattern printing film F is stored as an original roll, the coating film needs to be in a dry state. Therefore, when the pattern printing film F is used, before being supplied into the transfer tank 10, a solvent tank is used. It is necessary to make the activator S in 16 act to give tackiness. Incidentally, the activator may be applied to the pattern printing film F after the pattern printing film F is supplied onto the water surface.

In the hydraulic transfer printing, the pattern of the pattern printing film is transferred onto the transferred material so that a pattern is drawn on the surface of the transferred material by the overlapping of the color of the transferred material and the color of the pattern. Therefore, as the activator, a colorless and transparent activator has been conventionally used in order to make the best use of the background color of the transferred material, which has become common technical knowledge. On the other hand, in the present invention, the activator S is composed of a light-colored color which is a color contrasting with the transfer pattern P, and this is a characteristic structure of the present invention. Specifically, in this embodiment, the white-brown activator S is applied. The white-brown color is a color that can sufficiently conceal the dark brown color of the transferred material, and by selecting such a color with a strong concealing power as the color of the activator S, the color of the transferred material appears outside. Is prevented and the pattern becomes clear.

The pattern printing film F coated with the white-brown activator S in this way absorbs water, softens and swells, and spreads in all directions. When the tackiness of the ink and the spreadability of the water-soluble film become appropriate, the fishing rod A is attached to the gripping device 18 from above the water surface and approaches the water surface, and then the pattern printing film F is submerged so as to be pushed down.

As a result, the pattern printing film F adheres to the fishing rod A along the irregularities of the fishing rod A by water pressure and covers it in a film form.
The transfer pattern P is transferred to the fishing rod A. At this time, the water-soluble film F ₀ is partially dissolved in the water W, but in order to completely remove the water-soluble film F ₀ , a shower ring and water washing are separately performed after the fishing rod A has risen from the water. In addition, when the fishing rod A pushes down the pattern printing film F, air bubbles may enter between the fishing rod A and the pattern printing film F, but the transfer pattern P is not transferred to the fishing rod A at this portion. Without the activator S attached, the surface of the fishing rod A appears as it is and becomes the defective portion K.

The transfer state at this time will be described with reference to FIG. 3. The entire surface of the fishing rod A is covered with the activator S, and the ink of the transfer pattern P is covered with the activator S. As a result, the black-brown transfer pattern P clearly stands out due to the contrast with the white-brown activator S. On the other hand, the portion where the air bubbles enter and the dark brown that is the background color of the fishing rod A appears as it is because it is the transfer pattern P of the black brown that is the similar color around it, so it is not visually noticeable.

After the transfer is performed in this manner, the transferred material B reaches the ascending portion 13 of the transfer conveyor 11 and is discharged. After that, a product is passed through a drying process, a finish coating process such as a top coat, and a drying process. Become. In the present invention, the transferred material B needs to be a dark color, but this does not mean that the material of the transferred material B itself is a dark color. What is obtained as a result of coating or printing a dark color on the transferred material is also included in the "transferred material composed of the dark color" defined in the present invention.

[0018]

According to the present invention, a transfer target composed of a dark color is pressed against a water-soluble thin film in which the ink of a print pattern floats in an active state on the water surface, and a part or all of the transfer target is pressed. In the printing method in which the pattern is immersed under the water surface and the water-soluble thin film is removed with water while the pattern is transferred to the transfer target by water pressure, the pattern has the same color or hue and lightness as the transfer target. Since the activator is colored in a light-colored color, the transferred dark-colored pattern P becomes clear due to the contrast with the light-colored activator S, and also has a defect. The portion K is visually inconspicuous because the transfer pattern P and the fishing rod A have similar colors.
