Question about Pantone Colors

[jclements]

The thread, "Which color mode?" reminded me of an issue I have long wondered about. I rarely am required to use Pantones colors and if so it would be for simple, "pure" colored logos; most of the time I use the Pantone swatches solely to identify a set of colors I want to use in a graphic so this is probably a stupid question for the experieced graphics designer so excuse my ignorance.

If I do a blend between two objects which have Pantone Fills OR have an object with a gradient fill of a Pantone color to white, won't the resulting intermediate blended objects or intermediate colors of the gradient screw up things up for print shop?
