How is ink made?

Sennelier Dry fluorescent Pigments made ink how ?

• Sennelier Dry fluorescent Pigments , Alcohol / pigment ink

• Answer:

  I am not sure I understand the question. The inks are made by dissolving or suspending colored pigments in some liquid. Most pigments are colored because they have a large number of conjugated double bonds. Those bonds create what is called a resonance energy because they can alternate. That energy corresponds to frequencies of light they can absorb. That gives them color. Some metal complexes or compounds are also used.
