3M understands visual communication. We made the first thermo-fax machine for transmitting images. We redefined advertising with the first digitally printed, wall-sized graphics. We invented multilayer optical films that create crisp, vibrant images for electronic displays and counterfeit-resistant security marks. We’ve refined our inks and pigments to ensure true, bright colors that last, even under the harshest conditions. Building on decades of experience in print and digital technologies, 3M continues to introduce sophisticated films, inks, and software for print, electronic displays, and signage.
