    I keep getting this problem with our Sakurai. See image attached. When we increase the water it goes away but the water levels are very high and doesnt feel correct.

    Anybody know what it could be?

    Trying to keep posts on the forum in one common language, English.
    Could you possibly post in English?
    Many thanks - it is appreciated.

    We want to keep posts on the forum in one common language because it would be very confusing if everyone replied in a different language. Sometimes an auto translation may miss nuances or technical terms. Could you possibly translate before posting and post in English?

    Dear Adil,

    You had not given any solution for the "problem" from beginning. From beginning, you started your semaphoring in French, about your "solution" sent by a private message in his private inbox. And only after my comments on this spam, you started to share your comments here.

    Regards,
    Oleg T.

    it is also possible that the printing plate is faulty (oxidised). Insufficient preservation at the time of preparation or IPA % to low.

    Looks to me like your magenta ink density might be too high.

    Either plate problem, excess ink problem, dampening adjustment problem, temperature problem in the high printing unit which causes emulsion, or value problem.
