Gray is Green

[Ghost Prophet]

Nozzle check looks fine. Dampers look fine, can't see any signs of color contamination...

I thought it might be a Flexi problem so I tried printing gray on the other computer with Flexi and looks exactly the same.

Why is my gray green? -_-

Do a search on this site and you will find this explained 1,000 times. common problem.

Short Answer: C+Y=Green.

Longer Ansewer: The RIP is laying down too much of the Cyan and Yellow, and not enough Magenta to create a balanced, neutral gray. It is a color management issue, and not a printer problem. As Mosh said, do a search on this, and you will see a lot of discussion on this.

Thank you.

and Mosh should be specific about what to search for if he/she knows what the problem is. Not helpful at all.

CMY were all about 75% density, I set them to about 35% for a light grey to show up nicely.

i have the same problem - grey/green. i also have issues hitting a particular color i want sometimes. i do a small scale test print or panel a section and test print when it's critical, and then go back and make adjustments to the color in the design. I just accept this procedure as par for the course.(flexi/photoshop/outdoor jr., BTW)
Your solution will affect ALL the colors in your print though, wont it? You might want to sift through some more of those threads that come up on the "grey is green search".

Yep it will affect all the colors, making them a lighter shade. I'm okay with that and I think if you want everything to be perfect you have to make a custom ICC profile.

Is it possible to switch to grayscale?

This is the best way to go, create custom profiles for your media.

Even if you make our own profiles and everything is perfect, you still have to deal with inconsistency in the process.

Grays are tough to do well and really separate those that can from those that struggle. Be ready to make you own profiles as well as relinearizing and reprofiling if it has to be tight.

For those that make their own profiles, if you want stable greyscale output (without color anywhere), read your icc patches normally then generate the icc with VERY high K generation, a zero start for K, and very low total ink. Something like K start=0, Max K=100, total ink=200, max GCR. Then the only trick is to send only grey files. Don't expect this ICC to convert any color, just handle greyscales.
