jpeg save with a reddish tone

[roger_ele]

I had problems similar to this also - mine were fixed when I changed the settings in 'save for web' to 'use document color profile'

This would confirm the idea that the image is using a large color space, and the conversion is rendering certain colors to a reddish tint.

The problem with changing the profile in the "save for web" image is that while it may look good on your computer within PS, it will look bad on the web within a browser (or at least in non-MAC browsers). All Windows based browsers are non-color managed, and essentially view images under the sRGB color space. Newer MAC browsers are color managed.

The ideal fix would be to convert the image within PS. You can actually work on the image and see the actual final rendering in the proper color space by turning on "proof colors" (Ctrl-Y). No need to go through save for web to see what it may look like. Use the "View>Proof Setup" to set the color space you want to proof the image in. You can quickly toggle back and forth using Ctrl-Y.

As far as I know the only Browser that is color managed properly is the Mac Safari Browser. Just my 2 cents worth.

Gunner, Firefox 3 is also colour-managed (although not by default), and is in fact better than Safari.

[gholmes1936]

How does one color manage it then. In the prefs I suppose, but wherein is it please?

It was my understanding that at the time I originally read it that Safari was the only one that was color managed, but I have to admit that was some months back.

thanks for the tip.

No, not as easy as prefs - you have to manipulate about:config. But it's pretty easy.

Hi;
Just to keep it simple, something had changed on that computer at a fixed point in time. That's when things went goofy. Everything was OK until then. Now you got red and it prints that way. Some preference got changed or altered. I tried to duplicate that effect and didn't. Try the Adobe presets. What you got there is odd. Try making a grayscale with 20 steps and see if that effect is even or at a particular part of the scale. Could be some dopey thing in the color settings or a preset got changed in the custom set-up. It wouldn't be the first time. Does anyone else use your computer? Look for something dopey. The other guys covered all the other ground.

Thank you everyone for your replies and sorry I wasn't able to get back sooner to reply. I've been away. I am going get my monitor replaced as it looks like it could be the monitor. I will let you guys know if that's the fix. Thank you everyone for all the suggestions!

Doesn't sound like the monitor to me, but more like a profiles/color management issue... but how about you upload the file that turns red when you save for web? (both the original and the red version)
Then we can try to replicate it (it's SO much easier when we can see what's going on).

Also:
- What is your color settings? Try setting your working RGB to sRGB (and otherwise keep your settings like TommyO - but feel free to choose your usual CMYK/gray profiles)
- If you now create a new document and fill it with a gradient and something, will it still show red in the save-for-web?

If your image already has a set profile, changing the color options in photoshop will not affect it. Try going to edit->convert to profile and choose sRGB. Does this produce a red result? If not, try save for web and see if it still happens there.

Well, that was easy thank you.

The screen shot will show how I have my Photoshop CS4 set, as defined in a URL that I cannot remember.

Then I go to the menu bar in Photoshop and go to the VIEW menu and pull down to "Proof Set-up", which I have on the same setting, Adobe RGB 1998.
Now when I go to print, I set things up this way, see screen shot for my epson 2200 printer.

I sometimes have a similar problem but it's not always to do with save as etc it also happens when i make a duplicate of the image (Image>Duplicate) - the duplicate has completely different tones to that of the original as soon as it is created even though the color spaces etc are the same. If I restart PS the problem goes away. I guess it's just some type of glitch??

gholmes1936:
Your settings look fine, but i would turn on dithering and black point compensation. Or do you have a reason why that's turned off?
Also, your printing setup looks good, but I see you have set AdobeRGB as your printer profile - you don't have any specific for your printer?

Anyway, here's screenshots of my color setup (color management turned off in printer). I usually stick to sRGB as my working space at home (usually screen stuff) and AdobeRGB at work (usually print stuff).

I used the settings that the article said were the correct ones to use. Then tried it out on an image that I couldn't get to print anywhere near what my color corrected monitor was showing me. The screen shot was the one for the printing type of work space. When I do something for the web I use the sRGB IEC61966-2.1 space. I convert the image before going to the for the web compression app.

If one has both Photoshop or whatever application doing color correction and then g=has the printer set to do color correction one would probably be fighting themselves, so to speak.

Now please explain to me why have dithering and black point compensation turned on for printing something out? I'd be very interested to know that, for self education. I always learn something here, now if I can somehow manage to remember any of it, it'll be a red letter day.

[Chain]

Dithering is to reduce banding when converting between bitdepths, and black point compensation is to keep black black when converting between color spaces. I always keep them on (default) so I haven't really experimented with them.

You printing setup looked perfect, except that you just used Adobe RGB as your printer profile and not a profile for the actual printer (Adobe RGB as your document profile is good as it encompasses some printable colors that sRGB do not, but you will still have to choose the right profile for your printer when printing).
Personally I haven't calibrated my printer myself, so I use the printing profiles that Canon shipped with the drivers. I use "Canon MP610 series GL2" - that's for my printer, when printing on Canon Glossy Photo Paper with quality setting "2".
