Pantone colour confusion

[junglist]

This is not specifically an illustrator question, but I'm hoping someone can answer this question.

I'm currently working on a monotone project, using a pantone (4625) on an uncoated stock.

Here's my problem: when I select this pantone colour in I'llustrator it is listed as 4625 CVU, in Photoshop it is 4625 CV and on my uncoated swatch book it is 4625 U.

I don't want three plates separating when I send this to film, so can someone please put my mind to rest as to why this is so.

(I've got a suspiscion it is to do with the different vintage of each of the products ie. Illustrator 9 vs. Photoshop 4 vs. brand new swatch book)

change the names of the swatches so they are the same. This will make them print on the same plate
