Akua liquid ink

Bought some Akua liquid ink and had my first try using it yesterday. I'm probably not getting the retarder and ink ratio right on the first layer as it was a pain trying to get a completely opaque layer of black. You have to do lots of layers to get the opacity complete with their black ink. Other colours only need a few coats apparently. The ink didn't lift off my plates as much as I'd expected and has a very grainy appearance as a result.

Will try again with till I get it right or get to the end of the bottle at least! These first attempts are now going to be used as backgrounds for other bits of collage. I have a screen-printed astronaut that I did a few years ago and I wasn't sure what to do with it so cut it out to probably use with these and some other pieces.
