On large printed areas, I find it hard to get consistent ink coverage on cotton paper. Sometimes if the image is really large, I break up the plate into 2 pieces which works, but man, what a pain! Recently I started to wet my paper and it makes a world of difference. I take a cloth or sponge and wet it and wring out most of the water so your cloth is slightly damp. Depending on where the image is I will just moisten that portion of the paper. Make sure to just moisten the paper not drench it. I read somewhere that someone puts the paper in front of a humidifier to moisten their sheets. I think that’s genuis and I think I will give it a try.
