この発明は、パッド印刷の方法に関する改良に係り、紫

ド印刷が行えるようにしようとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement regarding a pad printing method, and is intended to enable clear band printing to be performed repeatedly even when using ultraviolet curable ink.
ところで通常のパッド印刷は、第１図に例示す（１）

う工程順に従って実行される。By the way, normal pad printing, as shown in FIG. 1 (1), consists of a highly elastic pad 1 attached to a pad support 2, and a printing plate 3, which is an intaglio plate, and is equipped with an ink pocket 4. First, the required amount of ink 5 is supplied to the ink pocket 4 of the printing plate 3 as shown in Figure (1), and then the pad 1 is pressed against the printing plate 3 as shown in Figure (2), and the band The ink 5 in the pocket 4 is received on the surface of the rose 1' as shown in Figure (3), and then this pad 1 is pressed onto the printing surface of the target article 6 as shown in Figure (4) to remove the ink on the surface of the rose 1'. 5 is transferred onto the printing surface as shown in Figure (5).

刷を可能ならしめ得る。Solvent-based ink is usually used for such band printing. This type of ink has the property of increasing its viscosity as the solvent evaporates, increasing its adhesion to other objects, and eventually solidifying. Therefore, when such an ink is used for the above-mentioned band printing, even during the short time that the ink is attached to the pad surface until it is transferred from the printing plate 3 to the target article 6, the viscosity of the ink is reduced by the evaporation of the solvent. The ink is easily transferred from the pad surface to the printing surface (2) and does not remain on the surface of the band, so that the ink remains clear next time. Printing can be made possible.
一方、紫外線硬化型のインクは、硬くて耐紫外線性の良
好な印刷被膜を形成することができるため、例えば耐擦

月されている。On the other hand, since UV-curable inks can form a printed film that is hard and has good UV resistance, they are prized for applications where, for example, scratch resistance or fading due to UV rays is a problem.

クは、印刷後に上記のラン（３）
プで紫外線を照射して展色剤を重合させ、言わば強制的
に固まらせる必要がある。However, unlike the above-mentioned solvent-based inks, this type of ink is a solvent-free type that does not contain any solvent, so it cannot be expected to produce any effects due to evaporation of the solvent, and therefore cannot be handled in the same way as solvent-based inks. . In other words, this UV-curable ink uses a synthetic resin that polymerizes when exposed to ultraviolet light as a color vehicle, and is made to harden through the reaction, and the color vehicle is not included in indoor lighting. It is adjusted so that it does not start polymerization under weak ultraviolet rays, but starts polymerization only when it is exposed to strong ultraviolet rays from an ultraviolet lamp, so its viscosity does not change even if it is left in the air. Therefore, it has the property of not hardening naturally. Therefore, after printing, this ink must be irradiated with ultraviolet rays using the lamp (3) mentioned above to polymerize the color vehicle and forcefully harden it, so to speak.
そこで、このような紫りＦ線硬化型のインクを前記した
パッド印刷に使用せんとするときは、次のような問題が
生じる。Therefore, when trying to use such a purple F-ray curing type ink for the above-mentioned pad printing, the following problem occurs.

転着され得ない。First, in the pad printing process shown in FIG.
This ink is transferred from the ink pocket 4 to the surface of the pad 1 without scattering at the stage shown in FIG. Although it is pressed against the surface, no increase in viscosity due to LJ is observed during that time, so it cannot be transferred to the printing surface as shown in Figure (5).

印刷を不鮮明にすることが多い。That is, as shown in FIG. 2 (1), which corresponds to the stage of FIG. Even if the pad 1 is pushed onto the printing surface of the article 6, the entire amount is not transferred to the core part, and when the pad 1 is pulled from the article 6, it is roughly bisected from the vicinity of the line 8-A in the figure ( 2) code 51
, 52, only about half of it is transferred to the printing surface (4), and the rest remains attached to the band surface. Therefore, on the printing surface, there are fewer votes of transferred ink 51 than expected.
The thickness of the printing film is thin, which tends to result in blurred printing with poor ink adhesion, and the ink 52 left on the pad surface may be slightly misaligned with new ink that the surface subsequently receives from the printing plate. However, the new ink often destroys the outline of the printed pattern and makes subsequent printing unclear.
よって紫外線硬化型インクは、上記したような実情のた

耐紫外線性の良好な印刷被膜をパッド印刷によって得る
ことが不可能視されていた。Therefore, due to the above-mentioned circumstances, UV-curable inks are currently considered unsuitable for band printing, and it has been considered impossible to obtain a hard, UV-resistant printed film by pad printing.
本発明は、かかる従来の実情に対処して、紫外線硬化型

第３図に示した実施例に基づいて説明する。The present invention deals with the conventional situation and makes it possible to repeatedly and easily perform clear pad printing using ultraviolet curable ink. At this step, polymerization of the color vehicle is partially initiated to slightly increase the viscosity of the ink, which is then transferred to the printing surface (5). The details will be explained below based on the embodiment shown in FIG.

Items marked with are the same, and 7 and 8 are ultraviolet lamps.
まず第３図（１）に示す如く、印版３のインクポケット

らない。First, as shown in FIG. 3 (1), a required amount of ultraviolet curable ink 50 is supplied to the ink pocket 4 of the printing plate 3 by a known means, and then the pad 1 is pressed onto the printing plate surface as shown in FIG. The ink 50 in the ink blur throat 4 is received on the surface of the pad. The process up to this point is the same as before.
このようにしてパッド表面へ移されたインク５０には、

Next, as shown in FIG. 1(3), ultraviolet light is irradiated using an ultraviolet lamp 7. Then, the ink 50 starts to polymerize the synthetic resin used as a color vehicle.
Viscosity increases. However, this ultraviolet irradiation is performed for the purpose of increasing the viscosity of the ink 50, and is not for the purpose of completely solidifying the ink.
従ってこの段階で使用される紫外線ランプ７は、出力の
小なるものでよく、またその照射量は、次（６）

粘性を高め（ｑる範囲で設定される。Therefore, the ultraviolet lamp 7 used in this step may have a small output, and its irradiation amount is determined by increasing the viscosity of the ink (q It is set within the range.

パッドの表面に残存することがない。Thereafter, as shown in FIG. 3(4), the batho F1 having the ink 50' which has been irradiated with ultraviolet rays is pressed onto the printing surface of the article 6. Since this ink 50' has increased viscosity as described above, it is easily transferred from the band surface to the printing surface and remains on the surface of the pad, as shown in (5) in the same figure. There is no.

に輪郭部れのない鮮明な印刷が可能となる。That is, the ink 50' that has been irradiated with ultraviolet rays can be handled in the same way as solvent-based ink when the solvent has partially evaporated, and the entire amount can be transferred onto the surface to be printed. This enables pad printing with a thicker printing film and better ink coverage.Also, since there is no ink left on the pad surface, it is possible to print clearly and without outlines in the printed pattern from next time onwards. becomes.

At 0', the viscosity is only increased compared to the initial level, and it has not yet solidified. Therefore, after the transfer, it is necessary to irradiate ultraviolet rays again with an ultraviolet lamp 8 (7) as shown in FIG. 3 (6) to completely cure the color vehicle and solidify it.

ができる。As described above, in pad printing using ultraviolet curable ink, the ink transferred from the printing plate to the pad surface is irradiated with ultraviolet rays to increase the viscosity of the ink, and then the ink is The printing method of the present invention allows band printing using ultraviolet curable ink, which was considered impossible in the past, to be relatively simple. This makes it possible to easily and repeatedly form a thick printed film on a printed surface with no outline blurring in the printed pattern.
