    I am having trouble with color and tried to recalibrate in Onyx 10 for my HP L25500. In the linerization table, it shows the yellow does not follow the other colors in a curve. It shows a message " There are places where the output curve is horizontal. One or more curves posterizes in the high end." I am not tech savvy at all, but I have tried to find information on how to fix this but cannot find the info in Onyx or HP. I have all new printheads installed, cleaned and realigned. I have run the recalibration a few times and viewed the Desired Targets graph and Swatch Measurements and Linerization Table, but it doesn't tell me how to correct the issues with the yellow. Colors are printing really bad.

    Can anyone point me in the right direction to learn how to do the corrections? Thank you

    What spectro are you using? It could be a problem with the measuring instrument.

    I've had that issue on a couple of my 25500s linearisations.
    It's not a deal breaker.
    If you're sure you're using the correct profiles etc I'd start again and make a new profile.
