Ink Opacity (or density) is the measurement of the amount of light a coating of ink allows to pass through it. Depending on the function of the label, this is measured using either a reflective or transmission densitometer.
Many label applications require a specific level of opacity. These applications include:
color is influenced by the bright metallic material, resulting in a metallic-looking ink color.
These are just a few of the applications where the opacity of an ink is critical. ALG has worked on many applications where ink or the label material MUST have the required opacity levels in order to meet the product performance requirements.
Our product managers work with our customers to determine these requirements, recommending the best label material and ink combinations to meet your opacity requirements.
In this video, you can listen in as one of our Product Mangers walks through the steps in using a Transmission Densitometer to read - and test - ink opacity.
This calibrated unit, provides a numeric value based upon the density or opaqueness of the ink that has been applied to the material.
In this example, the material itself is clear. A white layer of ink is then printed, and this ink layer must meet a numeric opacity value, confirming the product will perform as required.
