show an out of register 4/c print

Hi all

I need to show show what happens when  4 color process art goes out of register. The purpose is to mirror what  could happen when a job is printed

.Is there some way to shift the indiviual process colors while in separation mode? Ideally I would like to move the some of the colors a few thousands of an inch

Is there another way to achieve this

Thanks much for you help!
