Hi can anybody help me with a pointer as to where I can buy edible inks for an inkjet printer?

You could contact these guys

From that page:

The examples are such as the development and marketing the high grade sublimation ink (Using in heat-transfer
process), UV Active Ink (invisible ink that visible only under UV light), Edible Ink ( Ink for printing on cake, and cookie, FDA approved)
