Posca Paint Markers

Hi, everyone.

I know this isn't a color theory question, but this seems to be the most technical part of the forum.

I've tried a few different paint markers, and by far, the Posca paint marker has the best tip and is the most convenient and economical.

However, I assume they are not lightfast, as they are designed for posters. There's nothing clearly stated on their web site about lightfastness, either. (or pigments, etc.)

If I wanted to use them on top of acrylics on paper, is there a way that I could prevent them from fading? I'm assuming just isolation coat and varnish?

High flow acrylic paint is great. . .except, there is no good marker for them, and they take a long time to dry. (hours vs. minutes)

Thank you!

Re: Posca Paint Markers

This is the information provided by Amazon.com

Posca Paint Markers:

These opaque felt tip markers can write on a variety of surfaces including plastic, metal, wood, glass, plaster, canvas and more. Paint can be scraped off from nonporous surfaces like glass, etc. but will adhere permanently to porous surfaces such as wood, paper, etc. Water-based pigment ink is non-toxic, lightfast and waterproof. The ink won't bleed through paper (unlike alcohol-based markers) and is excellent for vibrant signs and craft work.

If they are pigment (rather than dye based) then they might work well. I'd imagine the yellow would be most likely to fade if they used something like PY3

I found this picture recently of lightfastness tests someone carried out with Posca pens. It looks as though most of them held up pretty well, with just a few fading.
