Anyone use Colorflow?How does its device link work?

[Bloodsaler]

Our Kodak prinergy system newly upgrade to vesion 5.0.And we buy the colorflow plug-in for this system.
The use of colorflow is simple.But i`m interested in the device link way.There are 7 devicelink choices in this software.The engineer says,when you set up 2 different output device,the software will automatically choose the best device link way for the customer.But i wonder the difference of each way.And this kind of device link way actually affect?

the 7 ways are(only the meaning,maybe not the correct name,because our system not English one):
1.no
2.use the import device link
3.chorm and black purity-keep solid
4.chorm and black purity
5.only black purity
6.keep the cmyk intergrality
7.totally seperation again.

when u make the devicelink profile and the purpose is color tone-scale matching then the best way is No.7 way.
