I think what you are talking about is to "print per Shirley".

There is a standard target called Shirley. This is a standardized image/negative that includes all colors and brightness range. Supposedly, lab technician will calibrate his machines so that Shirley will print correctly - correct color and correct density and all that. You *could* ask to have your neg be printed per Shirley with no corrections.

I wouldn't be surprised though, unless you ask this at a pro lab, you get blank stares....
