Thanks for your comments Tricia, always useful. The brown on the leaves is, of course red on green. My print run of 10 has widely varying greens and therefore 'browns' and also varying zingyness! I guess I could have mixed the red, green and a blue to make a black but it hadn't occurred to me. I masked the butterfly for the green print so the red would be bright. There's lots to think about isn't there?!!! Helen
