Not that great, as far as I was concerned. as the lines around the 'head' area were a bit of a mess.
So I added some carborundum to make the area darker and make the 'head area' more prominent. I actually can not remember how I did this or what I used but it still did not look satisfactory - either on the proof on white paper or on the inkjet itself.
The original was made using PVA and plaster powder I seem to remember and the plate became ever so thick and clumpy. I certainly wouldn't make it that way now but I think it was an early plate.
So that was that.
