Preview CMYK auto save, save, export
Help.... I have a jpeg picture that's going to a cd package. The picture is cmyk. Final package needs to be in CMYK.
When I put picture into Preview I can make all sorts of color changes just fine. But shortly after loading picture I get message: "The document could not be autosaved. Your changes will not be saved until the problem is resolved."
Then when I try to either save, after making duplicate, changing name, etc... or also try to export.... It gives error message; "Could not be exported, saved, as "picture name.
Why would autosave not save it...? I'm 10.7.5 OS I don't really understand autosave or seem to find access to control of it...
Why will it not save or export? This appears to be true of every cmyk picture I put in?
Why would Apple not allow saving, of cmyk....even when it can work on the file fine? Is it true that you can't save or export cmyk files at all?
What options do I have? Hard to believe "save as" isn't there. But I don't think it would work either.
Do I have to change jpegs over to RGB? work on them... and then change them back? How do I go both ways....? (easy there....)
Is there some other easy software I should use to change cmyk pictures?

I never use Preview for anything but previewing, not to say that it can't do wonders, but I wouldn't use it for conversions. First thing is if this jpg is being printed you need to make sure its at least 150 dpi (300 dpi is standard for printing usually). You also don't want to send a jpg to a printer, usually a PDF is what printers ask for. I am not sure if this is a professional job, as in using a print company, or if it is just for home printers that may have 4-6 colors in them.
You can download free trials of Adobe software on their site. After you download PS go to Image>Mode>CMYK and then save it as whatever you want.
If this going to a print company, you really need to talk to your print company and find out what they want, cuz you are in for a world of hurt sending jpgs to them.

Photo Shop is beyond my skills and not user friendly from what I can tell. I am using iStudio and think it is good for what I need. But its not a photo editor.
I do plan on sending pdf to the duplicator/printer. Which is what they say they prefer. However, they say that all pictures need to be cmyk. I assumed that means even when you send pdf, everything needs to be in cmyk. Not sure why in PDF that would be matter, but I'll take their word.
But my question still does apply to Preview. Why won't it save or export jpeg cmyk? How do I get it to? If it won't, do I have to change to RGB and then change back?

I don't know exactly what iStudio is but I'd think that any sort of image editor/paint package would have the ability to go from RGB to CMYK.
As mentioned, Preview isn't an editor and the RGB->CMYK is probably more something it happens to do rather than a primary function of the software. I'd do it in something else.

If you're dealing with CMYK files for print, then Preview isn't the right tool.
Photoshop has millions of options and features, but there's still a core group of functions that are essential for this kind of work. You'll find everything under the Image menu for colour correction and for setting the mode to CMYK.
There may be other (cheaper) software that can do the same thing.
If the JPEG is going to be part of a larger piece of artwork in Illustrator, InDesign, or some other DTP package, then the CMYK translation can be done when the press-ready PDF is made, if at all.
