What is the best way to keep promarkers vibrant on paper?

Unfortunately, our Promarkers are not lightfast and the only way of preventing fading is to keep them out of light, so work in a book or kept in a folder that can be closed off to light would prevent fading. Any form of display in the light will cause them to fade over time.

Are Promarkers lighfast/fade free if displayed? 

Promarkers, except for the Promarker Watercolours, are not lightfast. They are made using a dye-based ink, and anything dye based will be prone to fading.
