Researchers of ETH Zurich and ETH start-up company Scrona achieve a new world record! They have printed a color picture depicting clown fishes around their sea anemone home. This picture is as tiny as the cross-sectional area of a human hair.

As of today Scrona Ltd. and the ETH Zurich have been announced official World Record Holders for the smallest inkjet-printed colour image. The Guinness World Recors Limited achievement involved the use of the groundbreaking 3D NanoDrip printing technology, invented at ETH Zurich and now commercialized by the ETH spin-off company Scrona.
The printed image measures a minuscule 0.0092 mm2 in area, or 80 µm x 115 µm. That’s about the cross-sectional area of a human hair or the area covered by a single pixel of a retina display. Being so small, the image is totally invisible to the naked eye. To see it, the official witnesses had to use a special microscope.
