I have always had difficulty using Spotone to conceal dust spots on my prints. After reading this post, I bought a stick of Sumi ink, roughed up a sheet of glass using sandpaper, and tried it. I really like spotting this way!Originally Posted by Flotsam
The chief advantage for me was the ability to make a thicker ink which gave me more control over the brush tip.
Thanks Flotsam for the recommendation.
