Colors brightness change from a page to another page

[GRusso_RVS]

Hello to everyone, I don't know if it's a bug or not but when i move a graphic from a page to another page, the colors become automatically dull, losing all their brightness.

I also noticed that if I delete the image on the left side, the graphic return at the original brightness.

Are the red and blue shapes filled with RGB colors? Is there any transparency involved on the left page image?

If yes, all is normal: InDesign displays the page as it will be printed, with CMYK conversion.

As you can see in the photo, same pages and same mastro, the image on the left doesn't have any kind of transparency...

actually the only way that i found it's: delete the immage and redesign the container for that immage.

So, maybe there was transparency on the frame itself. Transparency in InDesign means a lot of things: drop shadow, opacity less than 100%, blending mode, and so on…

But anyway, be aware that these red and blue shapes will not print as bright as they are displayed. To get an accurate display, turn on “overprint preview” in the View menu.

The Transparency Blend Space is used for a spread’s preview when there is any transparent object on the spread.

You can set Edit>Transparency Blend Space to Document RGB and turn off Overprint Preview to get an RGB preview.
