For my Alcohol ink art, I use Copic and Ranger Alcohol Inks.
I find that copic inks in particular creates amazing textures when mixed with isopropyl alcohol. It is important that the isopropyl alcohol contains 95% alcohol or more in order to get the best result.
All paintings are on high quality yupo paper. Yupo is a 100% synthetic paper which is ideal for alcohol inks as it does not absorb the ink like normal paper but allows the ink to flow for longer. This allows the artist to create interesting textures.
I love working with Uni Posca Pens. The coverage of the pens are amazing. Posca pens are water-based pigment ink and works well on most surfaces. In fact, it is the only pen I have had success with on yupo paper.
