Lasercutting - RGB colours from Illustrator appear in grey/blackwhite after export to Rayjet Manager

[Patricia35124944sa29]

Hey there 🙂
I'm using Illustrator quite a while already to create the files for Lasercutting with Rayjet Manager (Lasercutter from Trotec) for my job. In my latest file I'm facing a problem which I never had before and couldn't find any solution yet. I hope to find some help here because this is my last chance. I'll be very thankful for any suggestions in short time.

A colleague of mine drew a design in ArchiCAD and sent it to me as a DXF file, which I opened in Illustrator and edited there. As I'm used to Illustrator, the settings like RGB colours, line thickness of 0.01mm & co are familiar to me and all set correctly. But nevertheless, when I 'print' the file to Rayjet Manager, there the red/black/green lines suddenly will appear in grey. I attached some partly screenshots to make clear what is my problem.
I already called Trotec/Rayjet Manager Support and they are sure, the problem is not there and I can also say that, because when I open a whole new document and quickly draw three circles - one in red, one in green, one in black - and then export that to Rayjet Manager, it is displayed correctly. When i copy part of the problematic design to that new document with the circles and export that again, it will appear in all grey again. So I'm pretty sure, the problem is with the imported data from my colleague. All lines are paths and after editing the design, I saved it as an .ai file.

Does anybody have any idea what could be the problem? Is there any setting in the background which is important? We already spent so much time in creating that design and finding a solution and want to produce as soon as possible.
Thank you sooooo much!

What about the color definitions or names?

And the color profile?

[Patricia35124944sa29]

Hello Monika 🙂 Thanks for trying to help.
The colour profile is set to RGB and the colour definitons are:
red / R255 G0 B0 / #ff0000
blue / R0 G0 B255 / #0000ff
green / R0 G255 B0 / #00ff00
black /R0 G0 B0 / #000000
as I always set them.

If that is what you were asking for 🙂

And you print directly from Illustrator?

If not, you might want to consider asking in a specialized forum where there are people who also use that printer.

In Illustrator I click 'Print' and then as the printer I select the 'Rayjet Manager Engraver'. But the problem isn't in the printer, because I already  installed it new yesterday and other designs are working well with that printer now - and the same printing settings. So I came to the conclusion that there has to be a bug/mistake in the design document itself but I have no more ideas where to search or what to try.

I SOLVED IT
If anyone is facing the same struggle, I quickly want to let you know what was the reason in my case:
I added our logo as a png to the design and after I removed that, it worked. So the png-file with transparent background was the problem. Now I included it as jpg with white background and everything is fine.
