Colour Channel DTF Printing

[ECLMB]

Hello all,

I am somewhat new here and recently purchased a DTF printer that requires me to use spot or colour channels. I have found some great videos on how to do it but the are for single images. We use what is called a gang sheet that is 15" X 60" that our clients that we print for, can add as many logos or prints they can fit on it for a per sqft price. Is there any way they we can spot channel the entire 15"x60" Gang Sheet? 

If there is anyone who knows or is familiar and can help, it would be greatly appreciated!

I have provided a video of what I need to achieve with channels below for refrence as well as an example of a file that we would need to perform the spot channel on.

If there is more information needed, let me know.

Thanks in advance.
