Information

Adding titanium dioxide to the ink will strengthen the coverage of the ink. And the produced ink is not easy to be eroded by sunlight. Therefore, it will be not easy for the ink to penetrate color and fade, so that the service life of the ink is longer.

 

 

What is the application of titanium dioxide in different inks?

 

 

- Offset printing ink

 

In the printing process of offset printing ink, the principle of "oil and water repel each other" is usually used to complete the printing process. Therefore, titanium dioxide used in offset printing ink needs to have good demulsibility and water increasing property. If the printed matter of the ink needs to be placed outdoors for a long time, titanium dioxide should also have good light resistance and weather resistance. Otherwise, the white ink produced will turn yellow and powdered.

 

 

 

 

- Gravure composite film ink

 

In the printing process of gravure composite film ink, in order to make the color of the printed matter more colorful and beautiful, white ink must be used as the base before color printing. In this way, titanium dioxide added in the process of making white ink must have very good coloring power and hiding power.

 

 

 

- Baking iron printing white ink

 

For baking titanium iron white ink printing, the baking temperature is as high as 180 ° C, and the baking needs to be repeated for about 2 hours. Therefore, the titanium dioxide in the white ink needs to have excellent heat resistance, otherwise, the white ink will turn yellow and lose luster during the high-temperature baking process. Serious cases may even cause the printed matter to be directly discarded.

 

 

 

Therefore, the ink has very high requirements for titanium dioxide, which is specifically reflected in the need for titanium dioxide to have

 

  1. High weatherability and heat resistance
  2. Strong coloring and covering power
  3. The particle size distribution is uniform and narrow
  4. Good dispersion
  5. Stable chemical properties
