I did these with another vinyl block, and discovered a couple of interesting things. The first is that – since the vinyl blocks are only 3.2mm deep, it’s almost impossible to avoid getting ink on the higher ridges outside the “official” design – it gives me interestingly unpredictable bits outside the edges. And if I try to eliminate them all, I end up going right through the block.
The second is the response of this particular paper – Atlantis heritage woodfree paper, 315 gsm, quite smooth and hard-surfaced – to soaking. The first image was done with dry paper, the second moderately-soaked – what I did was stack half a dozen pieces of paper up on a waterproof surface, giving each a thorough squirting with the plant mister before dropping the next on, and wiping off the surface water before dropping each one on the plate.
