每个图像都有一个或多个颜色通道,它们存储了图像中有关颜色的信息。图像中缺省颜色通道数依赖于其颜色模式。大多数情况下,图像的每个颜色通道包含8位数据,它们将转换为24位Lab位深度(8位×3通道)、24位RGB位深度(8位×3通道)、8位灰度位深度(8位×1通道)和32位CMYK位深度(8位×4通道)。
位深又称像素深度或颜色深度,它用来度量在图像中有多少颜色信息用来显示或打印像素。较大的位深(每像素信息的位数更多)意味着数字图像具有更多的可用颜色和更精确的颜色表示。例如,位深为1的像素有两个可能的值:黑色和白色,而位深为8的像素有256(2的8次方)个可能的值。

# means the image is untagged, i.e., Photoshop doesn't know what profile to use because the image was saved without profile information, and you have told Photoshop to not color-manage these images.
* means that the document colorspace is different from your working colorspace. This means the image had an embedded profile tag BUT that you have Photoshop set not to convert images to the working profile upon opening them (this is usually good). The * is just a reminder, the image should look "right" as long as you have your proofing set up properly.
/CMYK or whatever at the end means that the indicated proofing mode is being used (i.e. Logo, RGB/8/CMYK is using your preferred CMYK profile for proofing, so you can see how the image might look if, in this case, printed).
I think some of the problems you're having come from having Photoshop open an image with no profile info and either letting it convert the image to a different profile, or letting it assign a profile and tagging the image when it's re-saved.

以下是google翻译:
#指图像标记,即软件不知道使用什么设定档,因为图像保存的个人资料信息,你必须告诉软件不颜色管理这些图像。
*指的是,该文件colorspace不同于您工作colorspace 。 这意味着图像了一个嵌入式的个人资料标记,但你的Photoshop设置不转换图像工作概况后开放(这通常是良好的) 。 在*仅仅是一个提醒,图像看起来应该“正确” ,只要你有校对设立适当。
/ CMYK或结束时,无论是指表明校对模式正在使用(即商标, RGB/8/CMYK使用您的首选CMYK配置文件校对,这样你就可以看到图像看起来如果在这种情况下,印刷) 。
我想一些问题您遇到来自具有的Photoshop打开图像,没有个人资料信息,要么让它的形象转换到不同的个人资料,或让它指定形象和标记的形象时,再保存。
RGB/8#:表示当前图像没有嵌入色彩配置文件
RGB/8:表示当前图像嵌入了色彩配置文件而且与PS中RGB工作空间相匹配
