Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen printing method used as a method for printing on a sheet-like material made of various materials such as paper, plastic, metal, ceramics and wood.

[0002]

2. Description of the Related Art When performing screen printing,
Printing is performed by using a so-called screen printing machine and ink for screen printing. In this case, after the transfer of ink, the ink is dried for solidification and fixing. In the drying step, heating is generally performed, but it is usual that air is or is not sent together with heating, and the necessary time is given to the transfer material. Sometimes
In some cases, the heating is not performed, but only time is given. Since the dried products can be stacked, they are generally stacked and taken out from the apparatus.

As a recent tendency, various factors such as the development of various measurement and control systems as a trigger, the necessity of labor saving and the increase in the necessity of obtaining a large amount of printed matter in a short time,
The speed of operation is being increased. For this reason, the speeding up of the screen printing machine itself has progressed, and in response to the speeding up of the printing machine, the ink used has been devised so as to withstand the speeding up of the printing machine. For example, by using UV curable ink as the ink and using an irradiation machine equipped with a UV lamp to shorten the processing time after transfer, the speed of the printing machine itself can be increased. It is being used for.

However, the speeding up of the printing machine itself has progressed rapidly, and the use of UV-curable ink is still extremely insufficient. In other words, one of the features of screen printing is that the printed film is thick, but when using UV curable ink, there is also a relationship that the ink is placed on the surface of the object to be printed and then cured. , The adhesion to the surface is weak and therefore easy to peel off. This tends to avoid thickening the printing film, and tends to make it difficult to exhibit the characteristics of screen printing. Furthermore, even if you use UV curable ink and an irradiation machine equipped with an UV lamp for this, the curing process by irradiation and the required time thereafter are transferred using the conventional solvent evaporation type ink. Although the time is shortened compared to the case of drying, it is about one-third at most, and conventionally, about 600 sheets per hour is the speed of a printing machine that has speeded up to about 3000 or 4000 sheets. We cannot keep up with the progress. This means that in order to utilize a printing machine that has a high speed, it is necessary to make the drying processing device after transfer large, and it is necessary to increase the floor area for installing the device.
The actual effect of speeding up has been reduced, and in some cases it has become impossible.

[0005]

SUMMARY OF THE INVENTION In response to such a situation, the present invention fixes the transferred ink in an extremely short time without impairing the high speed of the screen printing machine which has been speeded up, and installs the equipment after the transfer. It is intended to provide a screen printing method that enables the printing of small items. Furthermore, the present invention provides a screen printing method using a conventionally used solvent-containing type screen printing ink, using an ultraviolet irradiation device, which makes it possible to make the processing time after transfer extremely short. It is provided.

[0006]

The present invention includes: A screen printing method comprising using a solvent-containing ink as the ink, printing with a screen printing machine, and then irradiating with ultraviolet rays. 2. The screen printing method according to the above 1, wherein the solvent-containing ink is used as the ink, the printing is performed using a screen printing machine, and then the ink is irradiated with ultraviolet rays and blown. 3. 3. The screen printing method according to 1 or 2 above, wherein a solvent evaporation type ink is used as the solvent-containing ink. 4. 3. The screen printing method according to 1 or 2 above, wherein a solvent-containing ink is used as the ink, printing is performed using a screen printing machine, and then irradiation with ultraviolet rays is performed, followed by irradiation with infrared rays. 5. As the solvent-containing ink, a two-component reaction type or thermosetting type ink is used, and the above-mentioned 4
Screen printing method described. By doing so, the purpose is achieved.

The details will be described below. First, in the screen printing method of the present invention, solvent-containing printing inks are used among solvent-containing screen printing inks, water-based screen printing inks, and UV curable screen printing inks, which are classified as screen printing inks. In the present invention, the solvent-containing screen printing ink is used for screen printing, and includes a solvent curing type, a thermosetting type, a two-component reaction type, an oxidative drying type and the like.
Of these, the solvent evaporation type is the most widely used, and includes vinyl resins, acrylic resins, polyester resins, polyolefin resins, ketone resins, chlorinated rubber resins, and cellulose resins. Acrylic, epoxy, polyester, etc. are used as the thermosetting type, and acrylic, polyester, epoxy, etc. are used as the two-component reaction type, and oxidative drying type as Alkyd type and modified alkyd type are used.

The ink is classified into a sticker, a poster, and an overcoat.
The solvent evaporation type is mainly used for stickers and posters, and the two-liquid reaction type is mainly used for overcoats. The application and the type of ink do not necessarily match, and an oxidation drying type is used for a poster or a solvent evaporation type is used for an overcoat. In the present invention, the use of ink is not particularly limited.

[0009] These inks have preferable characteristics for screen printing and have a characteristic that a thick film can be easily formed, but on the other hand, there is a problem that the working environment is contaminated by odor because of evaporation of the solvent. And sometimes the product has an unpleasant odor, which is not desirable. In either type, conventionally, after the transfer, a treatment for evaporating the solvent, that is, a post-treatment is required. For this reason,
A dryer is used to heat and accelerate evaporation, or the required evaporation time is secured on the conveyor. A predetermined long time was required both when the evaporation was promoted and when the evaporation was not particularly promoted.

The predetermined long time is not constant depending on the quality and surface condition of the material to be printed, printing conditions, ink, external atmosphere, etc., but in general, the shortest time is about several minutes.
On average about 30 minutes, in the case of special things more than 1 hour,
It took a few hours, sometimes a day or night. In the case of the solvent evaporation type, it is mainly used for paper, plastic film, etc. from the viewpoint of compatibility with the printed matter, and the time required for post-treatment is set to about 20 to 30 minutes. In the case of plastic sheets and metals, two-component reaction type and thermosetting type are mainly used. In the case of these ink types, 30 to 60 minutes are required for post-treatment, curing and drying. In the present invention, the time required for the processing after transfer is extremely short, and in the case of the solvent evaporation type ink, the time directly required for the processing is several seconds to several tens of seconds. Even when treating with a two-component reaction type or thermosetting type ink, the time directly required for the treatment is about 3 to 5 minutes.

In the present invention, the apparatus required for post-transfer processing requires an ultraviolet irradiation apparatus when printing with solvent evaporation type ink. When printing with a two-component reaction type ink and a thermosetting type ink, it is preferable to use an infrared irradiation device in addition to the ultraviolet irradiation device. The ultraviolet irradiation device used for the post-treatment needs to have a ventilation zone outside the ultraviolet irradiation lamp in order to further shorten the processing time. The blower zone needs to be blown with sufficient strength to prevent the printed sheet from floating. The applied air is vaporized or accelerated by ultraviolet irradiation,
Alternatively, the ink solvent excited to vaporize inside the ink layer is evaporated in a moment. Therefore, the wind does not need to be hot air or cold air.

Thus, the printed matter using the solvent-evaporated type ink after the treatment is subjected to the whole process at least 60 ° C.
Since it can be processed by the following, and because it is in a completely dry state, it does not deform due to heat of the printing material, it improves the accuracy when printing in multiple colors and there is no concern of blocking, and immediately after the drying process Piling integration is possible.

As described above, the ink used in the present invention may be any solvent-containing ink. Among them, those of solvent evaporation type, two-liquid reaction type, and thermosetting type are particularly preferable. Are particularly preferred. As the solvent evaporation type ink, screen printing ink using a vinyl chloride-based, acrylic-based, polyester-based, ketone-based, chlorinated rubber-based, or polyolefin-based thermoplastic resin as a vehicle can be considered. As the two-component reaction type and the thermosetting type, a screen printing ink using a reaction type resin such as epoxy, acrylic, polyester or a thermosetting resin as a vehicle can be considered.

The term "solvent separation" is used as an expression that means the degree of difficulty of the solvent used to dissolve the resin being separated from the resin in the drying process and being vaporized. Among the thermoplastic resins used as the vehicle, one having a good solvent separation is selected, and an ink suitable for drying by ultraviolet irradiation, which is most suitable for use in the present invention, appears. That is, the drying process can be completed in a limited space without any odor problem with the interlocking property that easily satisfies the capacity of the high-speed automatic screen printing machine of 2000 to 3500 sheets / hour.

In the case of the two-component reaction type ink and the thermosetting type ink as well, it is possible to shorten the total post-treatment time by using one having a good solvent separation from the thermosetting resins used as the vehicle. You can In this case, the printed ink vaporizes most of the solvent when passing through the ultraviolet irradiation device, and then enters the infrared irradiation device to complete the curing reaction. In the conventional method, only an infrared irradiation device or a processing device using hot air is used, but it is possible to reach predetermined ink characteristics in a significantly shorter time compared to these cases. Therefore, the present invention can be applied not only to paper and plastic sheets and films, but also to other materials such as plastic molded products, metals, name plates, glass, and wooden products.

The drawings schematically show the implementation of the printing method according to the invention. In FIG. 1, reference numeral 1 is an original fabric supply device. 2 is a screen printer, 3 is a conveyor belt, 4 is an ultraviolet irradiation device, 5 is a blowing zone, 6 is an infrared irradiation device, and 7 is a loader. The drawing shows the case where two irradiation lamps are used in the ultraviolet irradiation device. In this case, it is desirable to provide the irradiation zone for each irradiation lamp.
In any case, the air volume used in the air blowing zone is 9 to 30.
It is about m ³ / min. The infrared irradiation device is required only when the ink used for the treatment is a two-component reaction type or a thermosetting type, and is not required when the ink is a solvent evaporation type. The UV irradiation lamp used is generally used with an intensity of about 200 watts / inch. When using two stages of UV irradiation lamps, the conveyor belt is 18 to 35 m / when solvent evaporation type ink is used.
You can drive in minutes. When a two-liquid reaction type or thermosetting type is used, it can be operated at a speed of 0.5 to 1.5 m / min. The air-blowing zone needs only to be large enough to be incorporated in the ultraviolet irradiation device or the infrared irradiation device. There is no problem even if air is blown while irradiating ultraviolet rays or infrared rays. Therefore, it is not necessary to provide a special tunnel, and even if an air-blowing zone is provided, a length of at most 1 m is sufficient. Therefore, the entire device is very compact.

In carrying out the present invention, an ink selected from solvent-containing inks is used in the screen printing machine 2. If the printed material is paper, for example,
The sheets are fed to the screen printing machine 2 one by one from the state where they are stacked on the original fabric feeding device 1 and printed using the selected solvent-containing ink. The printed matter is then placed on the conveyor belt 3. The print on the conveyor belt is exposed to UV radiation and then blown with wind. Immediately thereafter, they are accumulated in the loader 7. When the ink is of a two-liquid reaction type or a thermosetting type, the ink is exposed to infrared rays after being blown with air, and then accumulated in the pick-up machine. The specific implementation status is shown in the examples.

Used the same. Printing was performed using the above equipment and conditions, and the obtained tin plate was irradiated with ultraviolet rays having an intensity of 120 W / cm. At this time, the integrated amount of ultraviolet light is
It was 2500 mJ / cm ² . Further, the material had a temperature of 155 ° C. under an ultraviolet irradiation lamp, and then returned to room temperature after about 1 minute.

Then, it was heated for 3 minutes with an infrared irradiator adjusted to an ambient temperature of 120 ° C. The material reached 150 ° C. when about 2 minutes had passed, and then reached room temperature after about 4 minutes.
After completion of printing, all the processing was completed in about 7 minutes and the collection was completed. The product obtained after all the treatments were almost completely dried. The methanol rubbing test is a simple method for evaluating the physical properties of this kind of ink film. In this test, a load of 1 kg is placed on a waste cloth impregnated with methanol or ethanol, the cloth is reciprocated on the ink film, and the number of times of reciprocation until the film is changed is expressed. The larger the size, the better. The number of evaluations of the product obtained by using this method was 19 times. On the other hand, in Example 3, the number obtained by using only the infrared irradiation portion without using the ultraviolet irradiation portion was 6 times. The two properties showed a clear difference.

[0024]

Example 4 Ink used: # 1400-120 White (heat curing type) manufactured by Seiko Advance Co., Ltd. Infrared irradiation machine: FC-3460 manufactured by Fuji Kagaku Kikai Co., Ltd. Conveyor speed: 0.5 m / min The conditions were the same as those used in Example 3 for processing. Perform printing with the above equipment and conditions, and print on the printed tin plate on the moving conveyor belt.
Ultraviolet irradiation was performed at an intensity of 0 W / cm. At this time, the integrated light amount of ultraviolet rays was 4000 mJ / cm ² . The material shows a surface temperature of 200 ° C to 230 ° C immediately below the ultraviolet irradiation lamp about 1 minute 50 seconds after the start of ultraviolet irradiation.
Two and a half minutes later, the temperature returned to room temperature. Subsequently, irradiation was carried out for 2 minutes with an infrared irradiation machine adjusted to an ambient temperature of 120 ° C.
The material reached 100 ° C. 30 seconds after the start of irradiation, subsequently heated up, reached about 150 ° C. 1 minute 30 seconds, and returned to room temperature about 1 minute after leaving the irradiation machine. After printing was completed, the processing was completed in about 8 minutes and the collection was completed.

The obtained material is used in the same manner as in the case of the third embodiment.
When the degree of curing of the ink was measured by the methanol rubbing test, it was 100 times. Also. The material was almost completely dry. This state is 15 when hot air drying is performed.
This is equivalent to the one obtained by heating and drying at 0 ° C. for 30 minutes, and the physical properties of the ink used, # 1400, have been perfectly exhibited. On the other hand, among the conditions in Example 4, the sample dried by infrared irradiation only, excluding ultraviolet irradiation, had a result of a methanol rubbing test of 5 times, showing that there is a problem in actual use.

As described above, according to the method of the present invention, when printing is performed using a solvent evaporation type ink, which has conventionally required at least 30 minutes, the post-printing treatment is only about 30 seconds when viewed by processing alone. All processes can be completed in 1 minute even including the collection. In addition, when printing is performed using a two-component reaction type or thermosetting type ink, the post-treatment time, which conventionally required several hours, and sometimes required one day and night, can be reduced to 10 minutes or less including the collection. It is a thing. Moreover, since the equipment required to obtain such results is compact, it does not require a large space, and there is no concern that the work atmosphere or printed matter will smell. Therefore, 3000 sheets / minute or 4000
Fully utilize the capabilities of an automatic screen high speed printing machine that exhibits a capacity of sheets / minute.

[0027]

According to the present invention, it takes a long time to perform the processing after the transfer, so that the performance of the high-speed printing machine with a good performance cannot be sufficiently exhibited, or a large-scale apparatus and a place for realizing the performance are required. It was possible to shorten the post-treatment time to an extremely short time by using a solvent-containing ink that is a preferable ink for screen printing, irradiating it with ultraviolet rays, or simply blowing air on it. It is a thing. Therefore, the performance of the high-speed printing machine can be fully exerted without the need for a specially large space or a large-sized device, and the adverse effects of environmental pollution that have occurred when the conventional solvent-containing ink is used. It is possible to prevent the above, and to bring about an extremely excellent industrial effect.
