I've been in web for a few years now so my print knowledge has gone a little rusty so I was wondering if someone might be able to clear something up for me.

I am designing a box which has a photo of the product on, this photo fades into black around the edges/in the photo background around the product. The client wants the background of the box to also be black.

Now a lot of you will already know where I'm going with this...

From the few prints I've done a while back, for printing black I used 100% K. However, the photo is RGB in photoshop. Obviously, the blacks don't match up.

Can/should I print using a rich black background for the rest of the box using % blend of CMYK that blends into the photo from Photoshop or should I convert the photoshop file RGB black into 100% K black? If I were to use the CMYK rich black, I'd convert the photo before print for press but would I lose the quality of the black (and photo) if I converted the photo to 100% K and went that route.

The route I am looking into is to CMYK rich black the box background and insert and convert the RGB photo. Would this be okay at print with plates and alignments?

To overview, excluding images, the rest of the box has some red and white text.

Any 'yes it's acceptable to rich black background print' or 'what in the name of all that is Holy do you think you're doing?! You need to do it this way...' comments would be much appreciated.

Apologies if someone has already asked this and many thanks in advance.
