Gray Printing Green - Help?

[Houston Button Pusher]

Mods, please move to a more correct section if necessary. thanks

I understand this is a long time problem for some folks and I've read up on several solutions, however I cannot turn my image into a B/W or Grayscale file as just part of my print needs to be gray and other parts are color. Specifically this week, I have a gray gradient frame around a CMYK image and the gray is tinted quite green.

I don't have access to the source files as these are customer supplied images (and they want a quick turnaround so we don't have time to educate the customer on the black arts of product photo production).

Printing on a Mimaki CJV30-130 but from reading, this is a universal issue. I don't have color troubles otherwise. Any suggestions would be helpful.

the gray is tinted quite green.

Does the gray scale in your quality control image look good when using the same settings?

Is this pre or post lamination? Laminating with some products like 3M 8518 has a yellowing tint that will change the color. Also try turning on or off color correction in your rip.

Why haven't the printer/rip manufacturers figured this out yet? Give the CMYK people what they need!

The printer/rip manufacturers all offer training, some free, some not.

What do you suppose the RGB people need?

Linearise with your spectro.

Training works great if you want to make your own profiles, been there done that for several years with all the gadgets. Just strange that printer and material manufacturers offer profiles that can't hit grays on CMYK printers. Battled with it for a long time on Roland and Mimaki. Just feel that it should not be a struggle.
