Hi
I've only had (or noticed, anyway) this problem when the balloon deflates, as the ink is then concentrated as the latex contracts and it becomes much 'thicker'. I've not checked their details, but perhaps they are only truly permanent on paper or card...?
It's an ongoing point of discussion as to which markers are best - to be honest, I don't really like black sharpies nor the maxiflo white board markers (although at least these should wash out of clothes) so I'm really stuck!! :?
Not much help really, sorry - just a comment!
