Separate and Colour Management
I have separate + but I don't have any instructions where to put it.

If I manually change color profile of gimp through preferences, will color data be expanded (Photoshop has higher color data than gimp).

I have many color profiles, attached. If not, what they do?

Is there anyway to work with same quality of graphics as with photoshop?

Same place as you put your other plug-ins.

However, separate plus is an old plug-in. Originally meant for an earlier Gimp.
With Gimp 2.8.x that set of files you have, gives an error message. This can be fixed with the addition of another dll.
This works with my Win 8 virtual machine, who knows if it works for you, try and see.

No, 2 different things. a color profile and a color depth. Gimp uses 24 bit color depth (3 channels x 8 bit), PS uses 3 x 16 bit. They can both use the same RGB color profile if you set it. The default Gimp is sRGB which is more than adequate for most use.

lots of reading here, please read it. http://www.cambridgeincolour.com/color-m...inting.htm

Some profiles, .icc especially CMYK are used by the commercial printer because inks and papers vary. The icc ensures everyone is working to the same pattern. Then there are profiles for monitors '.icm' which change the way the monitor displays colours, to get a better match with what you print.

It depends what you mean by quality. Color depth - No. CMYK - No Quality graphics - YES, depends on the effort you put into it.

A couple of notes. I do not think this applies to you but...
CMYK comes in for printing posters, leaflets, that sort of thing, using a commercial printer. If you are going for lots of this, Gimp is not the correct tool, Gimp is RGB, the separate+ plugin is a work-around at the best. Use something else (PS or Krita) and save yourself much grief.

Printing photographs, at home or at a printer, the default sRGB is fine. More important is getting your monitor set up to match output. Go back and read cambridgeincolour again.

You seem to have problems installing plugins. Do yourself a favour and install the Partha version of Gimp which comes with many of these popular additions. http://www.partha.com/

http://www.partha.com/ have mostly Linux versions. Any way to do so for my windows 8 32 bit?

Thanks I was looking for color depth, since I saw limited variety in colors.

Will there be any change in color depth like about 24 bit? In future plans?

For most things 24 bit is adequate, jpgs from your point-and-shoot camera, for example, will be 24 bit truecolour.

If you intend to do several intensive colour operations which might degrade the image, go for some pre-processing using something like photivo.
http://photivo.org/ Or you could always stop using Gimp and use PS.

Will Gimp get 48 bit colour in the future? Probably, but do not hold your breath. Remember that there are a tiny number of developers, who contribute their efforts for free and these things take time.
