I doubt I'll be buying this anytime soon since I'm broke, but if I happen to find $30 on the street then I'm definitely getting it. I was just wondering - does this stuff have a "speed" like photographic paper does? I was just thinking, if I'd be printing on wood or glass or metal, it would be kind of wasteful and costly to be doing "test strips" on the material I'd be printing on. Would this be the only way to get a good exposure though?

It varies. http://www.rockaloid.com/faq.html#27 Something like ISO 1/2 - 2

as it ages it gets contrast and speed.
you don't need to do test strips with the same material
you will be printing on,
just coat the same amount of coats of emulsion
on a piece of scrap paper.
the emulsion is the same whether it is on canvas
or paper or glass or ceramics or ...

good to see others using this stuff!

Thanks for the reply. Can't wait to get my creative printing on. Now just to decide what I want to print on!

What Mr Jnanian says...make your own test strips at the same time you coat your paper/materials.
