Color matching inks were intended for blending with other colors in the color matching system. Because of this, they tend to be more transparent in color. A color matching series usually contains 12 colors. When ink manufacturers use this series of colors, they’ve essentially made purchasing and mixing ink easier for their customers, as it means they have formulas for all Pantone® color charts readily available. If a customer needed to have color matched ink made every time they ran out, they would typically incur an additional color matching fee, in addition to receiving far more ink than they need–1 liter of ink can be expensive, especially when most jobs only require 100 grams. When only 12 colors are available to customers in inventory, the proper amount of ink can then be mixed for jobs on an as needed basis.
