Question

Color profiles in Acrobat for iOS not working?

  • May 12, 2020

I am working on a project in InDesign, and I am pulling in images that are saved with ProPhoto color profile. I am then outputting the file as a pdf with the InDesign setting "Color Conversion: No Color Conversion." When I open the document in Acrobat for iOS, the colors are completely wrong (undersaturated).

The pdfs look fine everywhere else (in other apps on my Mac and iPad) for Acrobat for iOS. I am trying to figure out if this is a limitation of Acrobat, which I can perhaps ignore, or if it is an indication that I should change the color profile of all the images before bringing them into InDesign.

I can post images if desired.

Hi Ayush


As I said, this is a problem for Acrobat for iOS (specifically, on iPad).


I just created a test case. I took a public domain large-gamut image and I used Photoshop to save it in four profiles (color spaces): ProPhoto RGB, Adobe RGB, sRGB, and U.S. Web Coated (SWOP). The first three of course are in RGB space, the last is in CMYK. And these color spaces are in order from wider to narrower gamuts. This means that the same numbers (in RGB) specify less saturated colors in ProPhoto RGB than they do in sRGB.

 

It appears that Adobe Acrobat for iOS is ignoring the embedded profiles, and therefore is rendering the colors incorrectly.

 

First the screen shots.

1) Adobe Acrobat on iPad (v. 20.05.00 (20200512.193622))

 

 

2) PDF Expert on iPad (probably uses Apple code to render pdfs)

 3) Adobe Acrobat Reader for MacOS (no apparent problem)

 

4) Skim for MacOS (uses Apple code to render pdfs)

 

I can give you the pdf that I used to obtain these results, and, in fact, the entire InDesign project so you can follow through how this was created, but I can't seem to do it directly into this discussion group. Let me know how you want me to proceed.
