Question 1

What applications is Pigment Orange 13 best suited for?

Accepted Answer

PO 13 is widely used in offset lithographic inks, publication gravure, and general industrial coatings where cost-efficiency and bright orange hue are priorities. Its moderate lightfastness (5–6) limits use to interior applications or short outdoor exposure. For packaging inks not requiring extended UV stability, PO 13 delivers strong tinting power at a competitive cost.

Question 2

How should PO 13 be dispersed for offset inks?

Accepted Answer

PO 13 is conventionally dispersed in linseed oil or alkyd varnish using a three-roll mill or bead mill. A typical pigment loading is 12–18% in paste form. Wetting and dispersing additives are recommended to achieve full color development and prevent flocculation. Fineness of grind should reach ≤10 µm (Hegman 6+) for quality offset work.
