The need for development
In recent years, with the continuous deepening of the concept of sustainable development and continuous improvement of end-user environmental awareness, the application of environmental protection ink in the field of screen printing has also made certain progress. With the advent of PVC-free thermosetting inks, water-based inks have once again become the focus of attention. Most ink manufacturers now offer this type of product to customers.
Water-based ink technology has made great progress in recent years. Due to the use of new wetting agents and emulsifiers, the drying of the ink on the screen is effectively mitigated. In addition, some new inks can even stay on the screen four to five times longer than before, and they will not block or dry. Even if the water-based ink loses its moisture under the action of a desiccator or extreme weather, it can be re-emulsified and utilized. At present, the shelf life of water-based inks has been significantly improved, and some products can even be stored for two years under the right circumstances.
Water-based inks have now extended their application to the market for thermosetting inks. The white inks that can be used to render dark clothing and the ability to print on high meshes make water-based inks infinite possibilities for users in an unprecedented way. For example, a halftone pattern is printed on a dark garment using the same mesh as the thermosetting ink.
In addition, printers can also use the latest development of modifiers and emulsifiers to adjust and manage the drying time of the water-based ink on the screen.
The last obstacle that water-based inks currently have to overcome is the use in special effects printing. As we all know, thermosetting inks are widely used in special effects printing. They can not only print high-density, gel-like, leather-like, metallic and thermosetting background colors, but also can be used to achieve various textures and glosses. Degree of text and effects.
Many curable and non-curable reducing agents can give thermoset inks softness comparable to water-based inks, but these types of reducing agents often contain PVC, phthalates, heavy metals and some It is a known hazardous substance and therefore has an adverse effect on the environment.
Many of the thermoset inks that are currently sold on the market that do not contain PVC and phthalates cannot be compared to thermosetting inks containing these materials in the printing of professional backgrounds. However, some of the latest water-based inks with higher solids content can expand their application range under the influence of a series of auxiliary additives.
Although we are not yet able to print transparent gels with water-based inks, you can create a variety of visual effects by adding metal powders, thickeners, and foaming agents.
The higher solids content of the water-based ink allows the printer to obtain a thicker ink film, which in turn gives the original texture effect. In addition, the user can also reduce the opacity of the water-based ink by adding water to print an ideal washing effect.
Remember that some additives contain neither PVC nor phthalates, nor do they contain heavy metals, pesticides, azo dyes, pentachlorophenol, or polychlorinated biphenyls, so from current standards, they are still very environmentally friendly. of.
Continue to focus on water-based inks
The extended shelf life will not only reduce the waste of water-based inks, but also increase their sustainability. All in all, the prospects of water-based inks are still very optimistic. The major trend of protecting the environment has now been verified in various fields of the global economy, and we also hope to see the large-scale application of environmentally friendly screen printing inks as soon as possible.
In essence, water-based inks play a very special role in the transformation of the screen printing industry. Although thermoset inks will not be eliminated in a short period of time, water-based environmentally friendly ink products will capture even greater market share - especially in the area of ​​specialty printing.
