"Inkers are not mind readers, we're not photo copy machines, and we are not robots."

-RICHARD FRIEND

I think the quote says it all.

Here's the rest of the quote:

"I've said this and dealt with that inking just about everyone.

Inkers are not mind readers, we're not photo copy machines, and we are not robots.

You are getting another human (although I guess a "trained" human) re-drawing your art....things are going to look different just based on the fact that the value a pencil puts down is totally different than the value you are going to get with jet black ink lines.

so you are screwed from the beginning basically."
