Why is there # after 16 bit sometimes?

[bunhong]

As you see, sometimes there is # after 'CMYK/16', and sometimes there is not.

What's the difference between them?

Hi

It means there is no colour profile associated with the file

Thanks a lot! This helped me a lot 🙂

The # means the image does not have a colour profile. So that image is in 16 bits/channel with a channel for each of CMYK, but no profile to tell Photoshop exactly what colour each pixel number in a channel represents. A recipe for incorrect colour.

A * in the same place means there is a colour profile but it is different to your default in colour settings (that should not be an issue)

A * at the end means the document has been modified and not yet saved

Hello, as the other have said, no color profile. you can get more tidbits of information at: http://morris-photographics.com/photoshop/tips/tips-interface.html

and of course at the user guide https://helpx.adobe.com/photoshop/using/workspace-basics.html

Thanks for the links!

In other words, that # means you're in trouble. It means you don't know what the colors are supposed to be.

But here's a much better way to keep tabs on profiles:

Thanks a lot! I will beware of it from now on...
