Last week I spent some time experimenting with a NuArc exposure unit in our printmaking lab and was able to make a couple of decent Van Dyke Brown prints.
I discovered that the shadow density on my negatives was a little high. I think the film I was using, being expired, had a bit more base fog than anticipated. That's okay as I was able to push through it for the most part. I also intensified the prints with some potassium dichromate.
Here are some digital images of the prints:
