Saved JPG or PNG images become over-saturated

I just got a MacBook Pro and installed Photoshop CC 2017 on it. When I open my image files everything looks normal, but when I try and export them as JPGs or PNGs to post on the web they become waay over-saturated.

I haven't changed any colour setting in Photoshop except View - Proof Setup - Custom, but that shouldn't have any effect. I have sRGB as a working profile and I save the JPGs with Embed Colour Profile. Still no dice... When I open one of my saved JPG in Photoshop again and re-save it I get even more saturation.. so it's definitely Photoshop and not the browser. Help!

Hey! I see you going way to deep on this, just wanted to share my solution for anybody else wondering like me few minutes ago.
For me saved images became too saturated because of weird export color management. If the pdf is in CMYK color profile it will convert colors of exported picture wrong. So you should convert color profile to RGB in acrobat first.
That solved the issue for me

Thank you for replying to a post from five years ago and sharing your thoughts. The OP has not logged in to the forums for three years and may not see this. She was not working with PDF or CMYK. Her issue was not using proper color management as detailed by @D Fosse and @davescm .

Hi Susanne

I am puzzled about the part that saturation increases every time you save.

Can you post two jpegs to help us please.

1. Saved as jpeg (with embedded profile as you describe)

2. Reopened and resaved as jpeg with no further adjustments (again with embedded profile)

Okay, one should never post support questions too late in the evening.. When I open the saved JPG in Photoshop it looks the same as the original, and when I re-save it it does NOT become more saturated. (I mixed it up w the screenshots I took and re-saved.

It's when the JPG or PNG image is shown in either Preview or in Firefox that it looks too saturated. (It actually looks better in Safari, even though I've heard FF has the best colour handling.)

So this looks more like a Mac display/Firefox combo issue than a Photoshop one. Any tips on how to make images look the same in FF as in Photoshop? Or does FF on Mac fall under 'non-color managed applications' like Per mentioned above?

When I got the MacBook I lightly calibrated it with the few standard options Mac OS allows to non-expert users. Now, after reading your input, I did a proper calibration with the slightly more professional options Mac OS offers (but has hidden from immediate view). With the new profile it looks about the same in FF, but the psd in Photoshop sRGB doesn't look so good:

Assigning the newly created profile to the image made it a bit brighter, but the colours were still much too saturated. It's weird, everything else (desktop, browser,) looks a bit better with the new profile, but not PS?

Woah pull back a bit.

The only way to produce a monitor profile is with a hardware device that reads the values of colours from your screen and then uses its associated software to do the maths and creates the ICC profile (and usually installs it on the system). The monitor profile should only be used by the color management system and operating system and never assigned to an image. This monitor profile is what tells a color managed application like Photoshop what actual colours will be displayed when it sends certain color values. That way the color management system can translate the values between your image and your screen so your display shows them correctly.

If you are serious about matching color - then such a device (such as the i1 display ) is essential. You can tweak some screen controls by eye (e.g. to match the white of printed paper) but you cannot produce a monitor profile.

Is you display calabrated well. Many users use their displays to bright and when they print or displaty their image on other displays they see colors that are much darket than they expect.

Thank you for the input! Yes it's calibrated. It's not the brightness that is the issue, it's the saturation. Plus like I mentioned the image gets more and more saturated each time I open and re-save it in Photoshop.

I don't use a Mac, but it seems that that the MacBook Pro has a wide gamut display, and on these displays images will display over saturated in non-color managed applications.

So the question is, in what application are you viewing the exported images?

And are you viewing on your own computer, or a different one?

When I open one of my saved JPG in Photoshop again and re-save it I get even more saturation.. so it's definitely Photoshop and not the browser.

Does the jpg look normal when you open it in Photoshop?

Where exactly are you seeing even more saturation? In Photoshop? In a web browser?

I haven't changed any colour setting in Photoshop except View - Proof Setup - Custom

Are you by any chance working with Proof colors turned on?

If your work contains saturated colors, and you have a CMYK profile selected under Proof setup, saturation will be reduced, because of the smaller CMYK gamut. Exported images (jpg and png) will then of course be more saturated than the Proof preview in Photoshop.
