Raw Materials (Resin) for SB Gravure Inks from Sunman
Apr 25 , 2021
What is Gravure Ink? Gravure (Rotogravure) inks are solvent-based ink with low viscosity, which can be quickly dried by vaporization. The advantages of gravure printing lie in the high, consistent, and continuously reproducible print result. Further, the benefit of fast-drying ink contributes to an immediate post-finishing of the printed goods. The ink is usually used in commercial printing of fle...

What is polyamide resin?
Jun 02 , 2021
Polyamide resin is reacted from dimer acid and diamine. This product is mainly used in gravure plastic printing inks and paper printing inks. It has very good adhesion on polyethylene material, especially be fit for printing on polyethylene film, plastic film such as tinsel composite laminated film. The printing ink which is made from this polyamide resin has good adhesion, high gloss, low freezin...

Difference between solvent based ink and water based ink
Jun 22 , 2021
Solvent based ink and water based ink is a different specification for each one of them. We would like to explain the differenct between solvent-based ink and water-based ink as follows: 1. After checked with this figure, It is easy to know that we can get Water-based ink by replacing most of the organic solvent with water 2. Water based ink on average dry at 1/5 of the organic solvent drying rate...

How to solve ink residual odor problem?
Jul 12 , 2021
We all know that surface printing ink must emphasize their luster as the film can not be supplemented by light. However, polyamide resin has a problem with residual solvent. Because the plastic gravure printing process is mainly by hot air to dry, hot air to dry the ink surface, the drying mechanism is from the outside dry, from the outside in, gradually dry out. But since the outside dries first,...

The Role of Wax Powder in UV Ink
Aug 05 , 2021
Wax powders can be used in UV inks, mainly for matting, non-absorbing, and non-foaming effects. In the UV ink industry, matting powder is generally used to achieve the matting effect. The disadvantage is that the matting powder has a great influence on the viscosity of the UV ink. The small holes in the surface absorb the solvent in the UV ink. When the solvent is absorbed into the matting powder,...

The Role of Wax Powder in UV Ink
Mar 01 , 2023
Wax powder can be used for UV ink, mainly for matting, non-absorption and non-foaming effects. In the UV ink industry, matting powder is usually used to achieve matting effect. The disadvantage is that matting powder has a great impact on the viscosity of UV ink. Small holes on the surface absorb solvent in UV ink. When the solvent is absorbed into the matting powder, the UV ink itself will become...
