Typical applications for conventional graphic screen printing are the printing of posters, displays, posters, and shopping guide signs.

Application field of UV pad printing ink

1. Graphic screen printing

Typical applications for conventional graphic screen printing are the printing of posters, displays, posters, and shopping guide signs.

Advertising materials, box printing, finishing and glazing are also included in this colourful field of application. Therefore, UV inks are widely used in the field of graphics.

This new ink technology is characterised by stencil stability and color accuracy, which ensures accurate color reproduction of repetitive jobs.

Applications in the graphics field may have a range of auxiliary processes for UV glazing, the ability to finish selectively or entire areas, or as a protective glossy surface to improve the durability of outdoor products.

2. Industrial screen printing

There are many kinds of applications, which are currently manufactured "in-house" by large manufacturers or through suppliers to industrial-related applications, such as printing contractors.

Due to the constant demand for new technological solutions for special tasks, industrial screen printing will continue to be used in the future, and screen printing often offers the best solution. Here, there will be many applications of UV inks, and new solutions with new technologies are decisive factors for future development and success.

In industrial applications, there is also a growing demand for productivity, environmental protection and application safety.

3. CD-ROMs

This is an extremely important field of application that has developed rapidly in a very short period of time. Compact discs include music and digital storage media such as CD, CD-ROM, CD-R and DVD. Screen printing is ideal for this complex, multi-application area.

For example, for long-run printing, the best print quality of four-color screened inks is the small dot enlargement, or the high edge definition of the yin text, which has become a key feature because of the increased quality awareness of the end user.

Currently, optical discs are printed exclusively using UV-curable ink systems. They meet the requirements of mechanical technology and guarantee the necessary operational reliability. UV inks can operate at a speed of at least 100 discs per minute and guarantee the lowest possible interaction between the ink and the information layer of the disc.

4. Packaging

"On the outside indicates what is on the inside". In order to ensure that product information, company logos, etc. are printed directly onto bottles, tubes, and containers of various materials, this is a multi-tasking task of UV screen printing.

This application requires a high degree of opacity, especially on colored substrates, with an attractive surface gloss and a very good anti-wear property. Of course, when applied to a variety of different substrates, such as plexiglass, PE, PP and PVC, or polyester, it is important that the ink layer has good flexibility. Previously, solvent-based inks were mainly used in this field, but now, eco-friendliness and faster UV technology prevail.

This part of the application also requires highly reactive inks, which can be used on machines with speeds of up to 100 rpm.

5. Labels

Label printing is closely linked to packaging because labels provide unique, individual, and informative communications, explanations, and explanations of contents, applications, and origins.

In addition, a well-designed label can further provide an attractive visual appearance, which in turn increases the value of the product.

Generally speaking, labels are usually produced with high-speed combination rotary presses, and in addition to letterpress and flexographic presses, there are one or more screen printing stations with a speed of 100 m/min. In this combination, UV technology offers real advantages, as highly reactive and fast-curing ink systems are the basis for this innovative production process.

Good opacity on dark substrates, high gloss or matte inks, soft ink films, and mechanical resistance make UV screen printing indispensable for label printing. Other strengths are special effects, such as fluorescent, bronze, pearlescent, and secure coding.

6. Certificates

Cheques, credit and phone cards, as well as club or delicate cards, are produced not only using a variety of synthetic materials, but also using different printing methods. Therefore, screen printing inks must be compatible with inks for other printing methods such as offset printing. They are matched with UV-curable glossy, matte or structurally glossy flourishing inks for screen printing. By mixing a variety of UV bright oils, the produced surface can be given a special effect.

However, the widespread use of UV inks in this area is limited to surface printing due to improper lamination, which means that it is not possible to produce sufficient adhesive properties between the ink film and the surface layer
