IrC2880 - color problem

[kuby]

Customer says the copies come out too blue. How do you adjust so the Test chart blue does not come out Purple?

Thanks

Drums are less than a month old, rollers and belts are clean. Gradation done. No change. Optics clean.

I assume that you have done the full adjustment from the user menu. I usually do it second time if image still seems bad after the first one.
So the print jobs are OK?
But for me the attached copy seems quite good. You can't get miracles when you do color copying.

What have you done sofar to the printer?....How old are the drums,transfer belt/ 2nd rollers?

if u have a Fiery connected, it is easy to change the profile

see attachment
efi Fiery Color Server Ref GU.pdf



Just remember> if u have a Fiery attached> u must calibrate the Printer first and do a color calibration for the Fiery

for the Fiery> I would remove all stored calibrations/ then re-calibrate with the Kodak Gray Scale
Best calibration is with a Densitometer

with a Fiery u can set up a Presentation or Photographic Profile,
use same profile on all iR's connected

Fiery RGB Rendering Styles:
• Photographic — Designed for images, retains the relative values between colors to maintain the overall appearance of the image. (resembling ICC Perceptual Intent)
• Presentation — Designed for bright colors, this allows saturated prints suitable to most business presentation needs. The Presentation CRD also does an excellent job of rendering photographic images. (resembling ICC Saturation Intent)
• Absolute Colorimetric — Maintains the absolute values of all in gamut colors to preserve the fidelity of single colors while rendering the paper color of the selected profile. (resembling ICC Absolute Colorimetric Intent)
• Relative Colorimetric — Maintains the relative values of all in gamut colors to preserve the fidelity of single colors while ignoring the paper color of the selected profile. (resembling ICC Relative Colorimetric Intent)

Fiery CMYK Simulation Methods:
• Full-Output GCR offers accurate proofing by performing a colorimetric conversion of all 4 plates from source to output color space. In this simulation method, the black plate is mixed into the CMY plates, then re-separated based on the Output profile.

• Paper Simulation automatically renders the paper white of the simulation profile as printable CMYK values in the output color space. This option is only available to those servers that have the Fiery Graphic Arts Package enabled. It is selectable when Full (Output GCR) is selected. Paper Simulation is only available in Job Properties and Print Driver. Paper Simulation is NOT available in ColorWise Pro Tools because setting it as a default can have undesirable effects.

• Full–Source GCR offers expanded full simulation capability by performing a colorimetric conversion from source to output color space, and maintains the distinction between Black and CMY in the original separation (usually performed in Photoshop or other separation software).

• Quick simulation is meant for documents which contain CMYK data separated for printing on a press, but which are being printed to the Fiery for short run production (“Output”), rather than as an actual press proof. Quick Simulation uses 1 Dimensional Transfer Curves to adjust output density only.
