Characteristics decide the UV screen printing ink application

Characteristics determine UV screen printing ink application

some people say that the UV printing ink used in screen printing is inevitable, its reason mainly depends on the characteristics of UV ink itself, so just what are the characteristics of screen printing UV ink?

　　（ 1) Fast curing, UV equipment is small in size, high production efficiency.

UV ink is perfect for multicolor, automatic assembly line, whereas the solvent ink dry need to configure the long dry line, even some dry monochrome print should around 10 m drying device. And after screen printing using UV ink, only need a UV light source can solve the problem, save the cost of equipment purchase, also save space, greatly improve production efficiency.

　　（ 2) Ink not blocking network edition, concentration is stable and suitable for high quality printing.

some people say that 90% of the problems in the process of silk screen printing is associated with solvent, solvent is an important part of the silk screen printing ink, but due to different regions, different temperature, humidity, ink of performance is also very different. So do not contain volatile substances, ink viscosity change is very small, easy to operate the UV printing ink, can well solve these problems, make the printing quality greatly improved. In addition, because of printing ink curing speed, shorten the printed residence time in the drying process, and reduce the dust pollution.

　　（ 3) Do not contain volatile solvent, no negative impact on the human body and environment.

at present, the commonly used silk screen printing ink, from yield and variety, volatile drying solvent ink accounted for the mainstream. Because of its slow drying time, 60% of the solvent will evaporate in the drying process, so the pollution to the environment. Seek pollution is small, quick drying, low energy-consuming UV ink, has became a common goal of the printing circles.

　　（ 4) Ink layer thick, substrates is widespread, operation simple and flexible.

general solvent ink, ink, solid content is about 40%, and the UV curing ink after the solid content of close to 100%, is generally 2 ~ 5 times of ink. If use thick film screen printing UV ink is better, so more suitable for screen printing.

　　（ 5) Wear resistance, solvent resistance, weatherability, etc.

UV ink through crosslinking reaction of chemicals in a stereoscopic polymer network polymer ink surface has a strong chemical resistance and friction resistance, and can reduce the print in the process of transportation due to the damage caused by bad environment, extend the period of some prints in the outdoor show.
