THAT crisp apple colour and that crisp apple smell could one day come out of the same ink-jet printer, if an idea hatched in a Japanese lab takes off. Using technology from existing ink-jet printers, the idea is to generate evocative aromas to complement images on your computer or TV, from the scent of a mown lawn in a family photo to truffles in a cookery show.
