Question

ePUB export image color change

The ePUB export process changes colors in JPEGs placed in my InDesign document. Any idea why and if there's a way to avoid this? 

 

InDesign v15.1.2

MacOS 10.14.6

 

Happens regardless of what seetings I select in the ePUB export dialog (except of course "Use existing image for graphic objects," which makes no changes to the graphics at all).

 

I do want to use InDesign for cropping and scaling the images. But I don't want InDesign to change the color values of the image.s

If you direct select the image, is sRGB listed as its profile in the Links Info panel? Also is your document’s assigned RGB profile also sRGB (Edit>Assign Profiles..., not the Color Settings RGB Working Space). And is the document’s Transparency Blend Space set to RGB.

    I have the same issue. The color profile of the linked illustration is sRGB, and the assigned profile in InDesign is also sRGB. Once I do the export, the colors are paler and I lose a lot from the original RGB color values. It looks more like what would be a CMYK output. Transparency Blend Space is set to RGB

    Do you have any idea why this is happening?

    Have you tried opening those images on photoshop and re-exporting for web use to make sure you color profiles are correct for web?

    The source image was generated using Photoshop's Save for Web tool. It uses the RGB color space and has an embedded profile: sRGB IEC61966-2.1. The image's background color is r197 g44 b47.

     

    After ePUB export, the image has no embedded profile, and its background color is CHANGED to r167 g75 b72.

     

    The actual color values are changed. Opening the image in Photoshop and re-exporting for web use after the fact makes no difference.
