Converting CMYK files to RGB in Indesign

Hi!

So I have two files and one of the files was originally set up as a print file (in CMYK) which I recently changed to an RGB file (changed in Document Settings and changed the Transparency Blend Space to RBG, re-imported all the vector graphics to RGB files) but when I export to PDF (Interactive) the colours still dull into CMYK colours. Exporting to JPEGs work though, it only happens when I export to PDF.

I have also tried to copy and paste the elements from the file into another file which was exporting my colours correctly but it still exports dull (so the other pages are okay but the page from the other file is still dull). I've checked and there's no transparency or drop shadows nor am I using PNGs in the page (it's only text and vector files which are exporting fine in my other files). I'm not sure what I'm doing wrong??

What export settings are you using in 'Export pdf > Output > Color conversion'? One of the files might have another color profile attached to it, which might result in different appearance

Keeping images in RGB is a best practice. Read more here:

Converting from cmyk to rgb does not bring back lost colors. Sorry about that.

Once they've ben converted to CMYK you've lost the range of colours, go back and use the original RGB images.

The image files haven’t been converted to RGB and I’ve gone and re-placed (cmd+d) all of the vector files and it’s still exporting dull (even as the same vectors are exporting fine on different pages in the same file)

Can you show us a screen capture of your PDF Export dialog? The 2nd PDF you linked to is all DeviceRGB.

AcrobatPro and Reader can simulate the expected CMYK output of RGB objects depending on your preferences. Under Prefs>Page Display>Page Content and Information there is Use Overprint Preview. If that is set to Always your page will display RGB color as a CMYK simulation.

Also, in AcrobatPro if you have the Output Preview panel open with a CMYK profile set in the Simulation drop down the preview will be a CMYK conversion.
