Išve been having trouble getting a good even color in my latest woodblock
print and I have been trying to figure out why this is happening. As far as
I can tell these are the variables that can affect the evenness of the
color:
Baren - pressure, quality of baren
Pigment - some colors are naturally grainy (e.g. French Ultramarine Blue)
Nori/Water/Pigment - ratio
Wood - type, grain
Paper - differences in texture, sizing, and fiber content
Admittedly I am working with an inexpensive baren and will need to upgrade
there. A better quality baren is sure to improve the evenness in tone. As
for the pigment, I have used Holbein mineral violet water color in many
watercolor paintings and have not found it grainy. Yellow ochre pigment is a
bit grainy, but seems to be less noticeable (probably because is it a
lighter color). Likewise, I am using a similar nori/water/pigment ratio as I
did in another print which did not produce this blotchy effect. I have also
tried using more or less water/pigment/nori with little difference. As for
wood, I am using shina which, as far as I know, shouldn't be a problem. So
paper seems to be the one factor that could be causing the blotchiness.
The mineral violet seems to be a bit less blotchy on the nishinochi paper.
Gampi and Echizen Koso were quite blotchy. (see my blog at
http://serendipityartist.wordpress.com for images of the blotchiness on
these papers). Oh, and I didn't get any blotchiness in my test prints on
copy paper.
Does anyone have any advice on how I can get more even color? I am ordering
a better baren and hopefully that will help, but maybe there is something
else that I can try?
Thanks for your wisdom.
