Hello Alexey, I´ve allready tried smoothing in PO (value = 10, max). My results basically stayed the same -aldough the dot gain curves looked quite nice & harmonic. The major problem was the separation. It was full of bumps, especially in the black channel. I´m quite aware that this problem can be partially solved using PrintOpen -but the profiles are IMHO far from being optimal. My idea behind this posting was something like "pushing the limits of argyll", since the print you evaluated ist almost a common condition in the packaging field. Thank´s for reply anyway.
