Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer film, and more specifically, when endless transfer is applied to the outer circumferential surface of a product having a cylindrical outer circumferential surface, the pattern or color joints caused by this transfer are The purpose is to prevent it from appearing on the outside.

Conventionally, when applying an endless pattern to the outer circumferential surface of a product with a cylindrical outer circumferential surface by transfer, the transfer foil itself is not endless but a strip, so it is inevitable that the connection position between the starting end of the pattern and the ending device cannot be properly aligned. Unfortunately, the joint between the female end and the terminal end of the pattern appears in the transferred pattern of the transferred product, which is a major cause of deterioration in the appearance of the product.

In particular, in the case of color changes, color density changes, and running patterns, the joint between the starting and ending ends of the transfer foil becomes clearly visible in a straight line, which has a very serious negative effect on the entire transferred pattern. .

The present invention was devised to solve the above-mentioned drawbacks of the transfer film, and it makes the density at the starting and ending ends of the transfer foil less than half the density of the main transfer area, and also covers the entire outer peripheral surface of the product as the main transfer area. The main transfer portion is covered so that the starting end and the ending end thereof overlap with each other. Embodiments of the present invention will be described below with reference to the drawings.

The present invention is a transfer film T for transferring onto the outer circumferential surface of a product S having a cylindrical outer circumferential surface, and the product S to be transfer printed by the transfer film T according to the present invention includes:
There are various products such as synthetic resin products and aluminum products.

As shown in FIG. 1, this product has a straight cylindrical shape or a straight cylindrical shape, and its outer peripheral surface is smooth over the entire area.

The transfer film T is placed on a strip-shaped base film T having a width sufficiently larger than the height of the product S, with a release layer interposed therebetween. Transfer foil T with a length that is an integral multiple of the outer circumference of product S
2 is attached.

This transfer foil L has a main transfer portion T2-1 in the central portion in the longitudinal direction of the transfer film T with a length and width that is an integral multiple of the outer circumferential length of the product S, and excluding this main transfer portion T2-1. The auxiliary transfer capital T2-2, which is the both ends of the auxiliary transfer portion T2-2,
The total length width of 2-2 is an integral multiple of the outer circumferential length of the product S, and the density thereof is less than half that of the main transfer portion L-1. In the illustrated embodiment shown in FIG. 2, the width of the transfer foil T2 is slightly larger than the height of the product S.
The length and width A of the main transfer section T2-1 are set equal to the length of the outer circumference of the product S, and the auxiliary transfer section T2-2
Each of these has a length and width that is half the outer circumferential length of the product S. Since the transfer film T according to the present invention has the above-mentioned structure, when the transfer foil T2 is transferred to the outer peripheral surface of the product S, the transfer foil T2 is wrapped around the product S in the form shown in FIG. It is transcribed by .

As is clear from FIG. 3, the entire area of the outer circumferential surface of the product S is covered by the main transfer portion L-1, and the outer circumferential surface of the product S is covered by the auxiliary transfer portions T2-1 and L-2. It covers the whole area.

In addition, the area where the ends of the transfer foil T2 are located in both the auxiliary transfer parts T2-1 and T2-2 is the main transfer part L-1.
is located.

On the contrary, the main transfer portion T2 of both auxiliary transfer portions T2-1 and T2-2 is located at the location where both ends of the main transfer portion T2-1 are joined.
The supporting parts of 1 and 1 will be located overlapping each other.

Further, on the outer circumferential surface of the product S, the main transfer portion L-1 and the auxiliary transfer portion T2-2 are always located overlapping each other. By the way, both auxiliary transfer parts T2-2 have a color density that is less than half of that of the main transfer part T2-1, but this auxiliary transfer part T2-2
Due to the difference in color density between the auxiliary transfer section T2-2 and the main transfer section L-1, the edge of the auxiliary transfer section T2-2 will not be clearly identified from the outside.

That is, in the parts M and N where the ends of both auxiliary transfer parts T2-2 are located, the ends of both auxiliary transfer parts T2-2 are always in a state where they overlap with the main transfer part T2-1,
Since this main transfer portion T2-1 has a color density more than twice that of the auxiliary transfer portion T2-2, the auxiliary transfer portion T2-1
The change in color shading that appears on the surface due to the loss of color becomes almost indistinguishable.

Furthermore, since the other auxiliary transfer section L-2 is always located in a portion where one auxiliary transfer section T2-2 is not located, there is no possibility that the above-mentioned color shade change will occur.

In this way, the transfer film T according to the present invention has the transfer foil L
consists of a main transfer section L-1 located in the center and auxiliary transfer sections L-2 and T2-2 located before and after this main transfer section 2--, and the color density of the auxiliary transfer section L-2 is Main transfer part T2
Since it is less than half of -1, there is no possibility that the transfer print edge of the transfer book T2 can be identified by the change in color shading.
It is possible to obtain a transferred pattern with completely continuous changes in color shading.

By the way, when trying to print not only color shading but also an appropriate pattern on the product S using the transfer foil T2, the transfer foil L is wrapped and transferred onto the product S using the outer circumference of the product S as a unit. When the pattern is transferred, the positional relationship is set accurately so that the pattern overlaps in a completely matched state without deviation, and the position is set so that it overlaps the main transfer section L-1 and the auxiliary transfer section T2-2. As with the ground color portion, the density of the portion located in the auxiliary transfer portion L-2 is set to be less than half the density of the portion located in the main transfer portion T2-1.

In this way, the color density of the pattern can also be made clear by providing a predetermined difference between the portion in the main transfer section L-1 and the portion in the auxiliary transfer section T2-2. Even the pattern located at the end of T2 can be made into a pattern with even color shading.

In addition, if the upper end surface of the product S is also to be transferred, this will be done in a different process from the above-mentioned transfer to the outer peripheral surface of the product S. The transfer foil must have a color density equivalent to that of the main transfer portion L-1 and the auxiliary transfer portion T2-2 of the transfer foil L, and the pattern must straddle the outer peripheral surface and the upper end surface of the product S. It goes without saying that the pattern located on the upper end surface of the product S needs to be accurately aligned with the pattern formed on the outer peripheral surface of the product S. It is necessary to have the color density when the pattern in - and the pattern in the auxiliary transfer portion T2-2 overlap.

In addition, in the above explanation, the length and width of the main transfer portion T2-1 is the product S.
The value is equal to the outer circumferential length of both auxiliary transfer parts T2-2,
This was carried out regarding the case where the total length and width in T2-2 is equal to the outer circumferential length of the product S, but the length and width A of the main transfer portion 2-1 and the length and width of the auxiliary transfer portion L-2 are The values of the total length and width of sections B and B are not limited to the above-mentioned embodiments, and each value may be an integral multiple of the outer circumferential length of the product S.

However, wrapping the transfer foil L around the outer circumferential surface of the product S and performing the transfer requires not only the transfer operation but also the transfer operation.
Complicated problems arise due to accurate positioning of the pattern and changes in the outer diameter due to winding, etc., which may cause surprises in performing a good transfer operation. The length and width A of the main transfer portion L-1 are set to be equal to the outer circumference length of the product S, and the auxiliary transfer portions T2-2, T2
It is preferable that the total value of the length and width B of -2, B2 be equal to the outer circumference of the product S.

In addition, in the above description of the present invention, the auxiliary transfer portion L
Although it has been mentioned that the color density of -2 is less than half of that of the main transfer portion T2-1, this means that the color density of the entire auxiliary transfer portion L-2 is uniformly less than half of that of the main transfer portion L-1. not,
This is an average situation.

Of course, the entire auxiliary transfer section L-2 is uniformly transferred to the main transfer section T.
It may be less than half of the color density of 2-1, but
Actually, it is preferable to apply a color density change that decreases the color density as it goes from the connection end of the auxiliary transfer portion T2-2 to the main transfer portion T2-- to the end of the transfer foil T2.

In this case, the density of the other parts is higher than that of the part M where both ends of the transfer foil T2 are located, but in many cases, this color density change is not discernible from the outside, and even if it is However, since the change is continuous, this change itself forms a pattern due to a change in color shading, and a clear change that distinguishes the start and end of the transfer foil stamping 2 never appears.

As is clear from the above description, the transfer film T according to the present invention forms an endless pattern by connecting the starting and ending ends of the transfer foil T2 transferred to the outer peripheral surface of the product S in such a way that they cannot be identified from the outside. As a result, the continuity of the endless pattern created by transfer can be dramatically increased, and changes in color shading can also be made continuous. Furthermore, it is possible to obtain a good transfer pattern, such as a good color shade change pattern without requiring strict alignment between the female end and the terminal end of the transfer foil T2. At the same time, it has excellent effects and can be easily performed using ordinary transfer techniques.
