I ended up printing the labels with my old inkjet and it actually worked fine. Condensation hasn't been a problem at all - I think the key is to have a design with not much ink. Semi skimmed milk for the glue was also a winner.
I printed off my labels with my normal printer they look great when dry but the ink runs as soon as there is any condensation. i.e. when I put them in the fridge. any solutions out there?
