Question

RGB Export of JPEGs changes color values

So, I have a strange problem and think I've tried anything possible but it still occurs:

I have a RGB document using only RGB colors. Everything is fine EXCEPT for when I try to export a RGB JPG. It completely changes they values of the color. It should be 130|40|130 and when I open an exported JPG in Photoshop and use the eyedropper tool it measures 146|67|146.

I've tried all three modes of exporting the image, with/without ICC profile. Color Management is turned off for this document (Edit > Assign Profile), and my color settings are attatched. Anyone have an idea what might be going on?

Thanks!

Can you share your problem document (or only the part that gives the problem)?

Otherwise we have to keep om guessing.

o m g guys, I've finally found the solution/the problem. 

 

In my document, the colored part was still an outline. So, I've expanded the appearance to make it a shape. Doing this messed with the colors (in the .ai file!). But after having it expanded and assigned the correct swatch to it, the colors match in the exported JPEG. 

 

No idea why Illustrator does this, but if you ever have this error - this might be the cause. 

 

Thanks for your help!!

Yes, that is a popular view, especially with those who are working that way still! However, RGB is increasingly taking over from CMYK in some markets and not others. Each has their strengths and weaknesses; the great strength of RGB is that the designer can work in accurate colour, leaving CMYK conversion to happen late, when the press is decided. It also allows output to entirely different models (like 6-ink output devices). One thing for sure: treating CMYK as generic is still very popular, rather than working to a press-specific profile. I believe this usage is slowly shrinking, and the people in this forum will generally call it out as wrong. This is region specific: RGB based fully colour managed workflows seem much more popular in Europe than the USA.

I think we need to look at exactly how you "turn it into a JPEG". Three ways at least. Please say what you do, and show a screenshot of your JPEG export settings.

Try using Bridge to synchronise your CC colour settings, then assign the sRGB profile to the AI file and export again.

I was going to suggest the same thing. It is important that all of your Adobe Applications have the same color profile settings so that they open apples to apples.

 

If you've never used the Bridge App, then open it, and do the following.

Quit all Adobe Apps, launch Bridge App.

-Go to the Edit menu and select "Color Settings".

-Select the color setting that you want to use across all Adobe Apps, then click "Apply".

 

This will synchronize all of your apps with the same color setting.

Is there no possibility to work outside of Bridge? Like, shouldn't sRGB be the standard for the Illustrator anyway?

Or is there a way to set it as the standard without using Bridge? I'm kinda hesitant to install it again, Bridge used to cause some problems in an earlier set-up.

Some colour change in JPEG is always going to happen, but not that much. So... Why would you want colour management "turned off" for the document? That would the idea of colour matching essentially beyond hope. However... I see no such option in Edit > Assign profile...

As far as I know 'Do not Color Match this Document' as selected is the preferred variable but I tried it with color matching as well and it didn't work either.
