problem printing on color brilliant carton

[carlopi]

hi all from Paris :-)
I'm a really beginner and I've made a simple logo. when I print it on white paper the colors are ok, if I try to print it on a red brilliant paper then I get only black
I try to attach the pics on white and on red paper.
I really thank you for your help, sorry for asking simple things but I am a real beginner :-)
merci !!

What would you expect as a result, carlopi?

Blue printer ink on red paper is near-black. This is called subtractive color, see https://en.wikipedia.org/wiki/Subtractive_color .

Or, in French: https://fr.wikipedia.org/wiki/Synth%C3%A8se_soustractive
