Been trying to find the perfect paper for my monoprints. Spent hours searching the net, but I think I've found some from GF Smith in Hull. They sent me two pieces of cartridge paper (and a sample book for free) to try, and I printed today. The paper is 135gsm which is a bit thin for the amount of ink I used as the oil in the ink seeped right through to the back. I think 175gsm will be better, but it will be more expensive. White 250gsm cartridge is perfect, but I'm looking for a colour to match the somerset newsprint I love so much. GF Smith have a cartridge called MIST which matches the colour very closely, watch this space for more details... BTW, the prints were fabulous! Will photograph them and post soon.
