CP2000 Characteristic Curves

[Bobby D]

Is there a press form that can be printed in order to assist in setting up characteristic curves on a CD-74? We have Printready, Signa, Meta, prepress interface and the CP2000 console on our CD74.

The guy who set up the original curves is no longer with us and the new guys don't quite understand it. I don't quite understand it either. We find ourselves just changing the curve "just to see what happens". I am looking for a more scientific way of handling this.

I handle all of the prepress proofing color management and process calibration of the plates using Color Toolbox 3.5. Everything is good till they start the job. They always make manual adjustments because "it always starts up (whatever color) heavy". There must be a way to assist in setting this up?

I'm just a prepress guy, not a pressman, but what is up with the Zx, Z1 and Z2?
Thanks,
Bob

yes there is a press form. yes they can come out and do it for you.

if everything starts up heavy just turn down the main percentage on the transfer. not sure how thats done on the cp2000 but on the classic console it looks sort of like a data drive/computer icon.

sorry not a pressman either.

There are several kind of characteristic curve in color management,I`m not quite catch what kind of characteristic curve you mean?The ICC curve,or the Compensation curve, or the CIP3 curve,or the ink-water balance curve?

i believe the easiest to get them back on track without messing with the color management that was previously set up is to change the compensation on the press. otherwise your into color management in prepress and thats workflow dependant and is going to be a longer answer.
