Rosin modified phenolic resin web transfer offset ink has many excellent properties, mainly as follows.
1. High viscosity
The rosin-modified phenolic resin has a large molecular weight and a high viscosity, so the rosin-modified phenolic resin web transfer offset ink has a high viscosity that cannot be achieved by other web transfer offset inks. High-viscosity ink has strong cohesive force. During the printing process, the performance is basically maintained through changes such as transfer, stretching and splitting, which meets the needs of today's high-speed printing.
In addition, because the phenolic resin has a large molecular weight, a high softening point and a high viscosity, the rosin-modified phenolic resin web transfer offset ink has good water resistance and gloss, and has strong adhesion, good abrasion resistance, and fast drying speed.
2. Low viscosity
The viscosity of the ink is not as high as possible. Only the ink with "high viscosity and low viscosity" is the ideal ink. Rosin modified phenolic resin is not only high viscosity. Moreover, it has good oil solubility and meets the low viscosity requirements of web offset printing inks. "High-viscosity, low-viscosity" ink has a good transfer, S raw and printability, printing dot complete, full, reproducible, graphic and clear.
3. Good liquidity
Rosin modified phenolic resin webs have high viscosity but good fluidity. In high-speed printing, ink with good fluidity can successfully complete the transfer, transfer, printing and other processes.
4. Good stability and strong adaptability
Because the rosin-modified phenolic resin web transfer offset printing ink has three characteristics: high viscosity, low viscosity, and excellent flowability, it ensures the ink has good stability and strong adaptability, and can not only meet the needs of high-speed printing, but also not easily affected by printing. The impact of the environment.
