Finally done with PMK. What next?

You can't print carbon without using a staining developer?

That's not what he said.

Normally silver and alt processes do best with negatives developed to different maximum densities. A negative optimized for silver or for alt processes will typically be difficult or impossible to print the other way. The advantage of a pyro developer is that it produces a negative that appears to have a higher density to UV than it does to visible light. The consequence is that when you get your process dialed in you can make negatives that print well both in silver and in alt processes that rely on UV exposure.
