In. my company we can print the color White as a spot color. Our printer reacts on the name of the color "White".

Until a while ago it was no problem to add a White color swatch to Illustrator.
Now I get an error (see image).

I don't know why it worked before and doesn't anymore.
May be it's possible to make Illustrator work like Indesign and change the name of the original white-swatch to Paper?
My problem would be solved :)
