Record the world's smallest color photo

The new world record of the smallest printed color image is about the size of a human hair's cross-section.

According to Slashgear, the photo was taken from a record aquarium with an area of ​​only about 0.0092mm ² , which is equivalent to a cross section of a human hair.

Researchers from the Swiss Federal Institute of Technology have partnered with Scrone startup to set the world record.

The printed image is too small to be seen with the naked eye.

The image is equal to a single pixel from the retina screen, measured in size from 80 µm to 115 µm. Researchers used NanoDrip 3D printing technology , a Scrona- owned printing technology to print the image above. The photo has a 24-bit color depth, making the printed image almost color-true in color in aquariums.

However, because the printed image was too small to be seen with the naked eye, the evaluation team from the Guinness organization had to use special microscopes to observe and draw conclusions.

ETH explained that images created through the use of quantum dot technology or nanoparticles can emit light of specific colors. These particles are dense, making the image more vivid and clear.

The researchers printed quantum dots into red, green and blue with a resolution of 25,000 DPI and a distance of 500nm.

The Swiss Federal Institute of Technology hopes that the new record will be recognized by Guinness organizations to promote new technological advances in the field of optics and display technology. Currently, Scrona is launching a fundraising campaign on Kickstarter to print these small record photos for supporters. Even the project supporters will be given a micro microscope to observe this special print photo. The fundraising campaign will last from now until 9/1 next year.
