Yes, but since almost all of the ortho films available today are lithographic films, the terms are often used interchangeably. The only non-lith ortho film I am aware of is Ilford Ortho+. I've used it for 4x5, and 4x5 pinhole work. The best description I've heard of is that is similar to FP4+ without the red sensitization. I'd agree with that.
