I will explain the way I work. But also provide links to sites and people working in a different or a more similar way.
I've not invented anything, I just put together a way of working and testing from all the information that is out there. Having a background in photography, etching, screen printing and a bit of copper photogravure helped a lot.

The polymer plate

As mentioned, you can only use certain polymer plates.

If you want to use the Dan Welden solar plates, there is only one type of plate. You can order five different sizes; 4x5, 6x8, 8x10, 12x16 and 16x20 inches.

Toyobo Makes all kinds of polymer plates, called Printight. This is what's on offer:


The one I use is the KM95R plate, in the yellow section. Steel based. Also the one most intaglio printing shops sell. Comes in standard international paper sizes up, to A1.

Your polymer plates will arrive in a black light-blocking bag. Store your plates in constant humidity, avoid heat and keep them away from light. Exposed, store them in an air-tide plastic ziplock bag. Before storing, clean well. Keep exposed plates away from heat and UV light, the surface might crack.

Polymer plates will not keep forever. Some say one year if well stored, some say less. So it is a good idea to keep your images (film) for future use.

It should be easy enough to find a local supplier or order from the internet.
I mentioned Dan Welden solar plates before, you can buy toyobo and den Welden plates from Polymetaal if you live in Belgium or the Netherlands.
