Introduction Sometimes it is difficult to read a seal or signature on a shin hanga print. Unlike many older ukiyo-e prints, the seal could be faded, rubbed, very small or printed in a color that blends into the background color of the print. Crepe prints can be especially difficult due to the process and the resulting smaller size of the seal. In this article I will illustrate one process for clarifying a seal. The following crepe print has a seal in the bottom right hand corner that is almost impossible to see with the naked eye. ![]() Unidentified print
1. Capture Image With Photoshop I truncated
the image to include the seal and its immediate surroundings. This greatly
reduced the image size, allowing the computer to process the image more
quickly. However, as the image to the left shows, the result is still not
very legible.
2. Lighten and Sharpen
Then I went to the filter menu and chose one of the 'sharpen' filters to make the image less fuzzy. This image shown to the right is greatly improved over the first step image. In many
instances we might stop right here and declare victory. But in this case
the seal is still difficult to read. Continuing the process, I was faced
with a number of choices. The path I chose seems reasonable but others are
possible.
3. Reconnect Image
4. Filter Background My approach is to apply the filter and then fade the filter (under the edit menu) and use the blending mode 'luminescence'. In the example to the right I used conte crayon. The seal is faint but the background is less distracting. The rationale for the previous step should now begin to be apparent. Note: in experimenting with the overall process, I found that this step added only marginal benefit, and thus could be considered optional. The 'optional' examples below depict the results without this Step 4.
5. Adjust Color The specific process was this: (a) I took the black out of the image's neutral tones, (b) I took much of the black out of the image's black tones, thus fading the background, then (c) I boosted the black in the reds (the seal). Finally there was some optional tweaking to take any red out the background, making the red seal more obvious.
6. Increase Contrast
The image to
the far right was achieved by a similar six-step process, only
substituting the 'solarize' filter for the 'conte crayon' filter in Step 4. Despite the difference in background color, the resulting clarification
of the seal is quite similar to that achieved with the conte crayon
filter.
Optional Results
The left image shows the characters before I filled in the crepe/wrinkle gaps, and the right image is after the gaps are filled in with a closely matching red color. I recommend clicking on each image here, to see a detailed pop-up view. They can both be opened and compared side by side.
Conclusion The above process is one way to clarify a 'difficult' shin hanga seal or signature. There may be other, more efficient approaches. And this process is only the beginning -- now I can start researching the artist's identity!!
