it's possible to read only one color chanel from tiff(CMYK) let say cyan and save it as greyscale?

Yes of course. Read the image in one buffer and write each 4th sample to a second buffer, After saving the second buffer to whatever format (tiff?) you are done.

If you ask for a ready made function in libtiff: there is none as far as I can tell. You must customise some code yourself.
