What factors affect the gloss of paste inks?
In paste inks, gloss depends on the quality of the dispersion and the particle size of the carbon black aggregate. The smaller the aggregate, the better the dispersibility and the higher the gloss.

Which characteristics affect the fade of the ink carbon black?
The particle size and dispersibility of the primary aggregates affect the hue. The smaller the primary aggregates, the lower the fade.

How to make carbon black?
95% of carbon black is made by the furnace method. Raw materials (petroleum) are injected into a high-temperature reactor, in which hydrocarbons are cracked and dehydrogenated to form carbon and graphite-like microstructures. Carbon black consists of tiny primary particles that fuse to form branched aggregates. Post-reactor operations include granulating "fluffy" low-density carbon black to improve storage and handling. Special manufacturing techniques suitable for improved dispersibility, cleanliness, and other key properties of the target are used to optimize plastic grades to improve the performance of specific applications.
