I work on paper and I use Copic and Shinhan alcohol based makers. I have an issue with white on top of such markers. It always yellows. I've tried Ironlak spray paint, Molotow, Unibal, Pentel and other white pens, Molotow One4All markers, Winsor & Newton white ink. Nothing has worked so far, it all comes out in a yellow hue to it. Is there something that looks white or is it just a problem of white reacting with the alcohol based markers? Any solutions?
I have only used about 2 prismas that I bought and are the most expensive markers I have. I used a deco color paint marker and it worked great. I then tried it again with a white sharpie and the white just went on the paper and disappeared.
