Ink Opacity involves the amount of light that can pass through the ink coating.   ALG uses a transmission densitometer to measure the opacity of label materials and ink coatings.


      Many label applications require a specific level of opacity.  These applications include:

  • Printing on clear materials that are applied to color surfaces that only want the surface color to be visible in the unprinted portions of the label.
  • Printing on metallic label materials where the customer desires the ink colors to not be influenced by the metallic surfaces underneath.  Conversely, in some applications, the customer wants a less opaque ink so that printed

      color is influenced by the bright metallic material, resulting in a metallic-looking ink color.

  • Two way door/window decals with messages on both sides cannot have message bleed through
  • Barcodes with white ink backgrounds on clear materials require an opaque white to allow for reliable scanning of these barcodes.


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 meet the required opacity levels in order to meet the performance requirements.

Our product managers work with our customers to determine these requirements, recommending the best label material and ink system to meet your opacity requirements.
