Hi! I have the sakura pigma micron and since I started to draw I have the same problems. I make the sketch in pencil, then I trace the definitive lines of the drawing with the pigma and then erase the pencil. The problem is that the line of the pigma also becomes smears and erased. I always wait a while for the line of the pigma to dry to paint the drawing with my markers based on alcohol (not copics) but the colors become stained and the lines end up blurred -again-. The drawing is very dirty as a final result. What do you recommend to address these two problems?
