How do you check and fix color profiles in InDesign?

To check and fix color profiles in InDesign, go to Edit > Assign Profiles to see the current document's color settings. You can change the RGB or CMYK profiles as needed. Additionally, ensure linked images have the correct profiles by using the Links panel and selecting Embed Profile if necessary. For final output, use Edit > Convert to Profile to match the destination color space

Lo correcto es sincronizar la Suite de Adobe, para eso hay que configurar el color en Adobe Bridge y guardar la configuración, un perfil recomendado es el Iso Coated V2 ECI. Para imagenes RGB el perfil recomendado es Adobe RGB 1998

Heh, that's an important issue. Most of the designers are using US web Coated (SWOP) profile because it's a DEFAULT setting in Adobe Apps. If you are printing in the EU - this profile doesn't fit at all. You need to switch to ISO Coated (at least). Just you need to know the location of the printing. The US, Japan, and Europe — are using 3 completely different sets of profiles. If I'm not mistaken - Asia, Russia, and the mid-east are using European profiles.

Picking the incorrect color mode can have devastating results, and this error can occur for professionals under high work pressure, not just beginners.

The magic key is the Synchronization of your profiles through Adobe apps. Open the Color settings in PS or Ai and take a look - are they synchronized or not? If not - open the Bridge and make all of your apps work in a single profile - in this case, INDD, Ai, and PS (and all others) will show you the same color.

The key to consistent colors across your Adobe apps is syncing your profiles. Check the color settings in Photoshop or Illustrator—are they in sync? If not, open Adobe Bridge to align them. This way, InDesign, Illustrator, Photoshop, and other apps will display the same colors.

This part is critical before exporting to a Print Ready PDF. Having the tools in Acrobat to preview your separations and colour modes is one thing, having it in Indesign is fantastic as you have not created any output files yet and have the power to change. As mentioned in the above comments, ensure you have the colour settings set up BEFORE you begin desiging the page, this will then aid in maintaining the correct colour and Pre-flight will hopefully catch anything imported or placed if its not a match. When finished with the design, check your separations and turn off the black, does your text disappear? if not, check your profile because black text should not be 4 colours (Rich black) generally. Spotting this now saves time later.

Think about what stock the design is going to be printed on. Is it a Coated stock? great, preview with ISO Coated_v2 all the way - should represent on screen pretty well, you wont be disappointed. Is it on Uncoated stock? ooh, dodge ball! change your preview to the Fogra47 or 52 or PSOuncoated. You will notice a huge shift in your colours, they look flatter, less punchy and bright. So many designers still do not realise the 'Uncoated effect' as I call it. Sometimes it can make a cool design look drab and life less, "but it looks fine on screen", most likely viewing it and designed on the ISO Coated profile so yeah will look great. Output a proof on an Uncoated Epson stock, and boom, cool factor gone. Better to proof and be sure.

I suggest investing time in researching this area as it offers a vast scope for creativity. Setting limitations can actually spur creativity.
