I'm looking for a supplier of plastic water bottles that can be printed in full colour....well, at least 4 anyway!

I've just spoken with a major supplier but they inform me they can only print 3 colours. I know we've touched on this before on the forum but thought I'd start a new thread so not to pull an old one back from the dead! :-)

Anyone have any experience of any suppliers? This is a good sized order that could well lead to a while lot more so rather than 'find' a supplier on Google I'd like to get a recommendation if possible.
