Thank you, Martin I'll have to figure that out. The last thing - for the moment - what I'm confused about is, that the shape of the Y curve is different between using the qm and the qh option. With the qh option Y is at an L-level 7 = 100 and K = 97. Also the total ink is higher than with qm. Maybe I should only use qm, this seemed to work more understandingly: L-level 7: Y = 97 K = 100.
