In the last article, we learned about the development of substrate in the development of dead materials. In this article, we will discuss in detail how the development of ink technology has profoundly affected the development of screen printing.

The development of ink and screen printing substrate development is complementary to each other, the rapid development of substrate rapidly promoted inks

The improvement of technology, the progress of ink and led to the further improvement of the substrate.

In recent years, screen printing ink from the traditional solvent – based oil developed to the present solvent – based, UV, water – based ink and other dry forms of the coexistence of the situation.

From the production efficiency, the use of UV di ink printing efficiency is higher than the use of solvent inks and water-based inks.Solvent – based ink and water – based ink drying generally requires drying rack or oven, time-consuming and energy consumption, drying process of waiting time is long.Seriously restricted the improvement of printing.Use UV curing.Ink through UV irradiation, instant drying and can be put into stock.It saves time and reduces energy loss:

In the face of the different needs of different customers different products, and a variety of silk screen printing ink and increasingly improved technology, provides the customer demand customization options, such as weather resistance demands, water resistance, solvent resistance, corrosive demands, friction resistance, high tensile performance requirements, ink specular/inferior smooth performance requirements, etc.In general, as long as customers put forward product requirements, there will be the corresponding ink to meet the corresponding.

It is also the focus of ink development and research and development to solve the increasingly strict environmental requirements faced by printing companies and break through the increasingly strict “green barrier” in the world.Even relatively contaminated solvent inks, are currently contained in a relatively mild, less harmful solvents to ensure that the ink in line with many mandatory regulations in the industry, such as ester, ether and other solvents.In terms of environmental protection, UV ink and water – based ink has inherent advantages, 100% of the UV system of ink, rarely volatile harmful solvents and other substances.With the gradual increase in the UV ink market, ink manufacturers also increased the investment in technology research and development, development to meet the needs of a variety of printing materials inks, now can be used to print UV ink substrate species has been more than before, such as polyester ink, hardened PMMA ink and glass printing ink.

Screen printing offers the possibility of using larger particles of pigment and having a thicker ink layer than the other three printing methods.With this kind of special screen printing inks, you can print a lot of special effects, such as imitation metal oil plastic, pearl-light ink, fluorescent ink and magnetic ink, at the same time, you can also use different effects, different particle size of particles to produce more special effects.Screen printing can also be used to reproduce the thick ink layer, can print braille, achieve light guide plate dot printing, 3D effect reproduction in the home appliance industry.

The development of ink has greatly expanded the printing method, improved the printing efficiency and reduced the printing pollution.
