ok, my hubby bought me an edible printer for Christmas and I was just looking at prices for ink refills. my question is can I just use regular food colors? like the airbrush food colors? Thanks!!

No No NO!!!! Do not use anything other then edible refill inks for edible printers.  The cartridges are specially formulated to work in the edible printers.  Food colorings and airbrush colors can ruin your printer.  Icing Images does sell quality edible inks

Air brush ink is different than edible ink cartridge and it will clogging your print  head.
