Highest jetness

Recommended grades：

WP906P、WP811P、WP305P-L

Carbon black is the most widely used pigment in black ink industry. carbon black could provide higher efficiency in 
combination with excellent fastness against light and temperature. Depending on the dosage and the resins, we recommend:
1. small primary particle and high DBP oil absorption enjoys a good jetness, easier disperse, and higher viscosity
2. the lower DBP oil absorption, the lower viscosity and the higher gloss
