Bonjour,

Je travail sur un fichier indesign (CMJN) qui doit être imprimé. Lorsque que je met un contours progressif sur mon image toute mes couleurs deviennent plus ternes. Savez-vous pourquoi ? Merci 🙂

Hi @caroline32204900iadi ,

because you are using an effect on your image you introduced transparency to this particular spread in your document.

If that happens InDesign is forced to simulate CMYK for screen preview. Only the screen preview changed. Not the RGB values of the image itself.

Merci pour votre réponse! Et à l'impression les couleurs seront ternes ou comme à l'origine?

Hi @caroline32204900iadi ,

one thing is clear, you'll see differences in the color appearance, because if your pages are printed in CMYK a color conversion must happen between RGB and CMYK. Read about color management on the web. The differences of the different color spaces. And the necessity to convert colors. How "dull" it will be printed depends on a lot of factors. One is the color management set in your document and of course the ability of your monitor to simulate the "right" color.

The best overview I found quickly about why and how do we need color conversions and color management is in the first 30 minutes with this video on YouTube. It's in German, but maybe you can follow along:
