Top performance with polarization filter

Dan Reid is a color communication expert and president of RPImaging. His main area of expertise is teaching printing companies about color and associated technologies. 

The challenge to obtain outstanding color results may differ from material to material, and some material, like reflective or shiny, might need a different approach when measuring.

Dan Reid:

Today, I’m going to talk to you about a little secret method I’ve been using for my clients to achieve better visual color matches and improve spot color measurement conditions.

I’m speaking about M3 measurement conditions or known as polarization measurements.

Simply, it’s just sunglasses for your color measurement device.

I have clients that typically print and use laminates or have extremely glossy materials like vinyl or metal.

And almost all of them suffer from having shadows that have no definition.


And this is because light is reflecting around bouncing off those extremely shiny surfaces. So when we measure with just a typical M0 and M1, normal measurement we find that the shadows look very murky.

Adding the M3 polarization filter cuts that reflectance significantly and results in having

  • a more shadow definition,
  • cleaner colors that appear to be
  • more vibrant

because we’ve removed that that veil of glare from a bouncing off the surface.

For some applications adding a polarization filter to the measurement process can help to achieve better color results.


Thank you for sharing your knowledge, Joe.
