When exporting web intent Indesign file some pages are defaulting to CMYK in acrobat

[amandac55703260]

Hope someone can suggest an easy out. I'm exporting a web intent document with an RGB colour palette to an INTERACTIVE PDF. When opening in Acrobat some pages are in RGB and some are CMYK - I'm using the same colour from the palette throughout. It seems to be a page problem rather than an element problem - I'm placing text which appears as RGB on one page and pasting to a page which displays CMYK - and it changes to CMYK on the page I'm having issues with - I'm guessing there's a page transparency setting somewhere I haven't found/used - (It's not the one in the pages panel - attributes - I've tried that too)

thanks!

Maybe a file issue. The little I know the intent should be a document level property. Try IDML export and then resaving back to INDD

Thank you 🙂 Sadly it hasn't made a difference...it's very frustarting...I've attached a couple of screenshots to help - same document, same colour, different pages

I should add, that it looks fine in the file preview - just not when opened in Acrobat

Hi @amandac55703260 , With Interactive PDFs, all color is converted to sRGB on export—doesn’t matter what the document Intent is. Acrobat Reader and AcrobatPro have a Page Display Preference that can affect the preview of RGB color. Try setting Use Overprint Preview to Never and the default blending space to RGB.

Marvellous Rob, thank you. 🙂 That's the ticket. After making sure each and every element wasn't set to overprint I didn't think to check if it was Acrobat. 

Very grateful !

In this case the term Overprint Preview is a bit misleading—it really means CMYK Preview. You can set the Overprint Attribute for an RGB color, but it doesn’t do anything—RGB colors can’t overprint. Here 100% Cyan overprints 100% Yellow, but the RGB equivalent of the colors do not:
