Description of the Related Art Conventionally, sticker printing has been performed in a roll-to-roll system, that is, paper distribution, printing, drying, and winding are performed in an endless sheet state due to the characteristics of a material wound in a roll shape. The printing method is applied to offset printing, gravure printing, flexographic printing, pad printing, screen printing, and the like, but pad printing and screen printing are predominant because of the variety of small-lot production and sharpness of printing. Of the various printing methods, pad printing and screen printing using UV ink can differentiate products with a high printed film thickness, excellent appearance, and high productivity that cannot be obtained by other printing methods. However, in pad printing or screen printing, the conveyance of the sheet must be stopped during printing by the tact printing method. On the other hand, in order to cure the ultraviolet curing ink, high-pressure ultraviolet irradiation is performed, so that the conveyance of the sheet in the curing zone cannot be stopped. This is because the surface temperature of the high-pressure ultraviolet lamp, in which 60% of the input is converted to heat, is as high as 800 to 900 ° C., and the material is ignited by stopping the conveyance. Usually, the solution is as follows. (B) A shutter and a reversing device are attached to the housing of the high-pressure ultraviolet irradiation lamp in synchronization with printing to avoid the influence of the heat of the lamp. (B) The transport system is provided with a hang-down zone between the printing zone and the curing zone, which hangs more than the sheet moving during the time required for printing. Are known as typical methods.

下させる。The method (a) requires a special device, a sensor, and the like, which not only increases the cost but also causes a risk of ignition due to malfunction of the device, which is problematic. The method of (b) is a simple mechanism and does not have the problem as in (a), but the UV curable ink does not dry out during the setting time of the hang-down zone because of its characteristics. Defects such as the adhesion of particles are likely to occur. Further, in the case of emboss printing, dripping of the ultraviolet curable ink tends to occur under the influence of gravity. The resulting repelling, dripping, and attachment of dust significantly reduces the commercial value of the seal. (B)
If the viscosity of the UV curable ink is abnormally increased or the viscosity is made thixotropic in order to solve the problems of the above method, repelling and sagging tend to be improved, but the print appearance is skipped, cross-cut, jagged, etc. Is caused, and the commercial value is also significantly reduced.

As a result of intensive studies, the inventor thought that the cause of the defect was that the ink did not dry unless irradiated with ultraviolet light, which is a characteristic of ultraviolet-curable ink. Therefore, an attempt was made to solve the problem by installing a low-pressure ultraviolet irradiation device between the printing zone and the hang-down zone or in the hang-down zone and performing preliminary drying.

計と言う観点からも採用はできないと考える。Experiments have shown that low-pressure mercury lamps used for disinfection and surface modification use a lamp having a peak at a wavelength of 254 nm to predry only the surface layer of the ultraviolet curable ink. A wrinkling phenomenon occurred between the hang-down zones with some inks, but it was found that improvement could be achieved by increasing the irradiation amount, such as by increasing the number of lamps. Experiments have shown that predrying of only the surface layer can also resolve printing defects in the hang-down zone. In particular, it was extremely effective in preventing dust adhesion. Experiments have shown that during printing, the sheet feed stops and the amount of irradiation partially increases, but because of the low-energy light beam, there is no change in appearance, performance degradation, or thermal problems. However, the lamp made of synthetic quartz glass emits 185 nm deep ultraviolet rays, so this wavelength with a large amount of energy selectively cures the surface layer and can only pre-dry the very thin film, resulting in printing defects in the hang-down zone. It turned out that it could not be solved. Further, it is considered that ultraviolet rays having a wavelength of 220 nm or less cannot be adopted from the viewpoint of increasing cost by providing a dedicated exhaust device for generating ozone harmful to the body and from the viewpoint of safe design.

ことがわかった。Low pressure mercury lamps used for medical and photochemical processes are lamps having a peak at a wavelength of 350 nm, and low pressure mercury lamps used for sunburn are irradiated with a UV curable ink at a peak having a wavelength of 370 nm. The experiment showed that the lower layer and the middle layer were pre-dried. Experiments have shown that defects in printing in the hang-down zone have a remarkable effect on cissing of UV curable ink and sagging in the case of raised printing. There is no effect on adhesion of dust because the surface layer does not dry. Furthermore, by selectively performing the preliminary drying of the lower layer and the middle layer of the ultraviolet curable ink, it was confirmed that the adhesion and the curing distortion were small and the physical properties were improved. It was also found that there was no problem in stopping the sheet feeding during printing, as in the low-pressure mercury lamp used for sterilization and surface modification.

せのみを限定するものではない。The inventor has confirmed through experiments that the characteristics of various low-pressure mercury lamps are examined and combined to solve all printing defects in the hang-down zone. That is, a low-pressure mercury lamp having a peak on a long wavelength side such as a wavelength of 350 nm or 370 nm and a wavelength of 254 n
It has been found that placing the low-pressure mercury lamp having a peak at m in front and back solves all the printing defects in the hang-down zone. However, the problem of dust adhesion is a physical phenomenon and is selected according to the specification, and is not particularly limited only to the combination.

ましい。By installing the low-pressure ultraviolet irradiation device between the printing zone and the hang-down zone, or at the entrance of the hang-down zone, defects occurring between the hang-down zone can be prevented. There is no particular difference in effect due to the positional difference between the two. It is preferable to install at the entrance of the hang-down zone because the whole apparatus becomes more compact.

Usually, a high-pressure mercury lamp or metal having an output of 80 to 120 W / cm can use a ride lamp. Metal halide lamps have high luminous efficiency and are suitable for curing colored inks. A reflector using a vapor-deposited glass, a heat ray cut filter, or the like can be used as a material that is weak to heat.

にも安全で低コストの設計が可能となった。The seal printed matter obtained by the present invention has no print defects such as repelling, leveling defect and sagging, and a high quality appearance can be obtained. In particular, emboss printing is several hundred microns
In addition to no dripping even with a printed film thickness of m, the edges were smooth and lacked sharpness in the setting of the hang-down zone. This gives the product an appearance that has a high commercial value that could not be obtained in the past. In the past, the convection phenomenon during setting sometimes caused a partial variation in the gloss, but preliminary drying immediately after printing enabled uniform and reproducible printing. The present invention, which solves the defect in the hang-down zone by mounting only a low-cost and low-pressure ultraviolet irradiation device which is safe and inexpensive, enables a safe and low-cost design for the device.
