    Default KM C6000 (with RU): How often do you calibrate the Fiery?

    Hi!

    I'm a little bit curious about calobration frequency of a KM C6000 which is equipped with an RU509 (decurler and inline densitometer).

    KM's sales guys of course tell me that I almost never need to do the Fiery based calibration after the initial setup and some technicians even told me that it might be a bad idea to do so because I could loose the "link" between the machine's linearization target values and the corrections, the Fiery does on its own target values.

    But there are other opinions as well...

    So the question is, should I just lower the frequency of Fiery based calibration, compared to other printers without inline density measurements or should I really avoid calibration?

    I just heard a story about a service tech telling his customer that it is impossible, on his Fiery based system, to have a color click on one side of a sheet and a black click on the other side of the same sheet.

    Over the years I've heard lots of service techs spout blatantly wrong things. So, consider your source.

    Calibrate as usual, have the tech set up CDC, and turn it on for your blank white stocks. Every 1000 or so sheets. It's no big deal.

    And keep calibrating on the same schedule. Often.

    Well said ;-) nothing more to add but one thing:

    By "CDC" you're talking about the interval, the internal instrument will re-linearize the engine, aren't you?

    CDC = Color Density Control. It's the functionality enabled by the RU densitometer. Yes, it's feeding back to the engine to keep the engine more consistent.
