Just found this list, have a question

My shop prints vehicle wraps for military vehicles, which means we print a LOT of brown. We print on Mutoh Toucan LT 54" inkjet printers, and we have two. (We need a third one and have cash; anyone who knows the whereabouts of a new-in-box one should e-mail me off-list.) Our RIP is Onyx ProductionHouse 7.1. We print on MACtac 5529 gloss and 5828 matte vinyls, MACtac window perf, and LG Chem banner stock.

This week I printed four vehicles. Three of them are covered in my shop's "photo stealth" camo, which is pieced together from scanned photographs. They printed really close to what we expected, and the unit that owns them is happy.

The fourth one is the problem, and this happens basically all the time. The fourth vehicle is printed in "digital camouflage," which is just rectangles created in Illustrator. We create a camo made up of four shades of dirt brown and send it to Onyx. The color values say brown. The picture on the monitor of the machine that made the camo is brown, and so is the picture in Onyx. So...obviously you'd expect SOME shade of brown, but we get your choice of the following:

four shades of yellow-green
four shades of magenta
four shades of blue
two shades of magenta, two of blue
four shades of really shocking orange--as in the shade of orange Circus Peanuts come in.

If you rasterize it in Photoshop you get the same revolting colors.

Our profile settings:
Input: "SWOP 2.0"
Rendering intent: Saturation (I've tried Perceptual, Relative Colorimetric and Onyx Graphics' Poster Color intents; the color changes a little but it's still not brown)
Output: "Default Printer" as set by Onyx for this machine.

A few weeks ago we changed from Wincom Digital's third-party ink to Mutoh's OEM ink. All the profiles we have were built with Wincom's ink. Obviously there's going to be a color difference...but green? We don't have our own spectrophotometer. I borrowed an Xrite 508 from a friend and built a new input profile, which is prettier than

Any help would be appreciated. I'm pulling out hair over this one and I don't have all that much of it.

Thanks in advance.
