Colour variation Indigo???

How is the density kept stable on these machines? Ours seems to move around a lot? I can always see a difference in the proofs from day to day.
Our old Indigo seemed to be way more stable.

Thanks

I know on the 5000 that you are supposed to check the oil/ink density in the ink tanks. It seemed like a lot of maintenance to have the press print correctly. But there are many variables that cause bad prints on the 5000. Correct me if I'm wrong, but I believe if your oil and ink mixture isn't correct then you will not achieve good prints. I remember there being a tall beaker that you use in the back to measure oil flow. That could be off. Blanket temperature could be a problem as well. If you are not measuring your substrates and putting in the correct settings in the software then that could be a problem as well.

Not sure if that's what you were meaning but thought I'd try to help.

first you have to performe a full calibration, and smal one every day.
clean your spectro first
good day
