Do we have color separation feature available in sdk java?

We have requirement to spot the color and separate color channels from pdf in CMYK colorspace followed by combining the particular color channel. For Ex. combining just the CYAN and MAGENTA separations (or any combination of colors) to make a PDF file and the output PDF from the combo is in color and not greyscale.

Can we achive this by using java SDK programmatically?

If we can, then please kindly let us know the way to achieve the same.
