Researchers Redevelop Micro-Scale ‘Great Wave’ Painting Using Inkless Technology

Katsushika Hokusai is the titan of Japanese art, as revered in his homeland as are Da Vinci, Van Gogh and Rembrandt Van Rijn within the West. Of all his famed masterpieces, the “Great Wave” stands out as the ultimate testimony to his creative genius.

Now, a staff of researchers at Kyoto University has created the smallest “Great Wave” ever played, just one millimeter in width. What’s more, they made it without using pigments. Not only is the “Great Wave” copy the world’s smallest, but it’s also the first ever printed without using a dye.

Professor Easan Sivaniah of iCeMS, Kyoto University, where the research was conducted, says, “Polymers, when uncovered to emphasize—particularly, a kind of ‘stretching out’ on the molecular degree—bear a procedure called ‘crazing’ wherein they form tiny, slender fibers often known as fibrils. These fibrils trigger a visible sound effect. Crazing is what the bored school student sees when he repeatedly bends a clear ruler until the extended plastic begins to cloud into a type of opaque white.”

Considerably, the iCeMS analysts realized that by controlling a course of known as organized microfibrillation (OM), which describes the way the microscopic fibrils develop and arrange in a periodic sample, they could additionally manage the scattering of sunshine to create colors throughout the whole visible spectra from blue to crimson. Thus, it includes a method for printing that does not rely upon pigment.

The OM technology permits an inkless, large-scale color printing course that produces photographs at resolutions of as much as 14,000 dpi on numerous flexible and transparent formats. This has many functions, for instance, in anti-forgery know-how for banknotes; however, as Sivaniah emphasizes that its features go way past typical printing ideas.
