Suminagashi marbling is a Japanese paper marbling technique that involves floating sumi ink on water in concentric rings. While relatively easy, there are still a few things that can go wrong while you’re marbling, so here are some tips if you’re running into trouble on your marbled paper. This post was originally created to accompany my Suminagashi instructions found in the tutorials section of The Little Book of Book Making.
Here are the sources of the Suminagashi materials that I’m using in these photos:
Black Ink: Yasutomo Liquid Sumi Black Ink 2oz
Color Ink (above): Aitoh Marbling Kit
(note: Do NOT get the hanshi paper, it’s too thin)
Brush: Chinese Calligraphy Brush
(the quality of this brush isn’t crucial since you’re only using it to dip, not paint – just get any of the same type of “medium” size – one for each color)
I’m thinking of selling kits of black ink, dispersant, paper and brushes for $20, but I’d like to gauge interest before I buy stuff – leave a comment if you’re interested!
Problem: Ink isn’t Floating
Answer: add another drop of dispersant to your ink, squeeze any excess ink from your brush with your fingertips, or try skimming the water before adding ink to the surface.
Problem: Ink rings are blurring after you make a print
Answer: try holding your brush in the water for less time, so that less ink is deposited on the surface of the water, and/or after you make a print, submerse the entire sheet of paper under the water bath and gently shake back and forth to dislodge extra ink.
Problem: “whisker” marks on your marbled paper
Answer: lay the paper down more gently when you take a print – whisker marks are caused by tiny air gusts flowing under the paper as you lay it down on the water’s surface. (they can also be a neat effect to experiment with)
Problem: Ink rings aren’t expanding
Answer: Skim the surface of the water with newspaper strips thoroughly before you start adding ink to the water – dust trapped on the surface increases surface tension, and doesn’t allow rings to expand properly
Problem: Water is getting murky
Answer: squeeze excess ink from the brush with your fingertips, only dip the very tip of the brush on the surface of the water – no deeper than 1/8″ – imagine only dipping your fingernail into the water.
