Metallic Inks: More Control on Press

[para. 1]: "In the past, the color control of metallic inks on press was not an exact science. Most of the time when metallic inks were on press, a visual acceptance by the client was used to control the color. Metallic inks cannot be measured with a densitometer or spectrophotometer that uses a 0/45- or 45/0-degree configuration because the gloss from the metallic ink gives false readings. Previously, the only option to measure metallic inks was to use a spectrophotometer with diffuse lighting or d/8-degree measurement geometry. However, this type of spectrophotometer is usually not found in a pressroom."
