I started out my attempt to learn how to create a color gradation in moku hanga, by reading the method described in The Art and Craft of Woodblock Prinmaking.
I started the process by moistening the wood with a wide brush and letting it soak in.

I added drops of watercolor pigment (I used Winsor yellow and alizarin crimson) to the top and bottom of the block respectively.

Then I added the nori or rice paste between the drops of pigment.

Next I used the maru bake brush to blend the pigment and the nori. I swiped the brush in small circles at first and ended with a side to side motion, gradually moving toward the center of the block where there was no pigment and only nori and water.

It took a few prints before the block became “seasoned” enough to print well. I noticed that too much water caused spots in the print and too little water cause lines. I had to practice to get the right combination. Things got a bit messy as I swiped the brush from side to side, so I used masking tape to protect the edges. I still had to wipe the sides off, but the tape helped keep things under control.

Here is a print of the gradation. This will provide the background for the tree and clouds.

Nice demo. What does the nori do?

Hi Gregg,
Thanks for commenting on my blog. Nori rice paste is used in Japanese-style woodblock printing. Without it the water based ink doesn’t print smoothly and creates speckles. There is more thorough description on the McClain’s website at http://www.imcclains.com/catalog/ink/nori.html.
By the way your corn print is awesome. Also, congratulations on getting a gallery to represent your work. The Book Abbey looks like a cool place.

The subtle colors are very gentle and beautiful to see the steps that you took to make the gradated print.I am inspired to try this now.
Aloha,
