Question

Which of these is not an example of a possible additive used in ink?

Answer 1

Answer:

greases

Explanation:

Ink is manufactured in two stages: first varnish (a mixture of solvent, resins and additives) is made and then pigments are mixed into it. Varnish is a clear liquid that solidifies as a thin film. It binds the pigment to the printed surface, provides the printability of the ink and wets the pigment particles. Ink made with color usually includes the following ingredients: petroleum distillate solvent, linseed oil, some form of organic pigments, and soybean oil. Inorganic pigments are not commonly used.

Additives play a critical role in the formulation and production of inks, helping to impart the necessary characteristics the ink needs, whether it is to run more smoothly on press or to protect the finished product.

However, grease is not one of the likely additives to ink hence it is not essentially used in ink production.
