Attached is a jpg. The original file was created in Illustrator.

The top rectangle in Pantone 1405 M.

The bottom rectangle is it's CMYK conversion. C: 0, M: 36, Y: 100, K: 63.

If I litho printed these, would they come out differently?

What is the advantage of using the Pantone color? From what I understand, Pantone is made up of CMYK inks.
