Print Hi-Tech: April
Printing, digital, and marketing convergence
Today: the first character-named Pantone color in the company’s history; an ultra-thin film that changes its color like a chameleon; liquid-metal alloys for inkjet printing on flexibles; the fifth International Arsenal Book Festival in Kyiv.
Minion Yellow: an official new Pantone color
Pantone announced its first-ever character-branded colour inspired by Minions. Pantone Color Institute describes it as an ‘illuminating, energetic, friendly and fun-loving yellow shade that immediately calls out to you’.
While the Pantone Color Institute noted that consumers were eager to add energizing colors into their lives, Pharrell Williams, who took part in creating the music for the Despicable Me, came up with an unusual idea. Together with Illumination Entertainment, Pantone team reviewed the existing colors to find the closest representation of the iconic yellow shade.
The result was the Pantone Minion Yellow, the custom warm and playful extroverted hue, meant to be associated with intellectual curiosity and enlightenment. It will be added to the PANTONE Fashion, Home + Interiors color palette with the next color addition.
Chameleon-like material changes color on demand
UC Berkeley engineers created an ultra-thin film that can shift colors when flexed or bent. With most natural and artificial materials, color depends on chemical composition. Changing color, therefore, requires changing the material chemistry. The new silicon ‘skin,’ on the other hand, leverages ‘structural coloration’.
In their research, engineers cut rows of ridges on a layer of semiconductor silicon a thousand times thinner than a single strand of hair. Each of those ridges reflects a specific wavelength of light. As the silicon is bent or flexed, the structure of the material changes, becoming green, yellow, orange and red.
Because the material is lighter and more flexible than previous variants, the color-shifting effect could have a wide range of applications. The material would work well with outdoor entertainment displays. It would be useful for military applications, including camouflage. Its creators believe the material also has potential in building safety. The silicon could be used in sensors for bridges, airplanes and buildings, changing color in case of damage or structural stress.
Inkjet can become compatible with liquid-metal alloys
Inkjet-printing technology may soon find its way into mass production of flexible electronic circuits based on liquid-metal alloys. Elastic technologies might bring a new class of pliable robots and stretchable clothing created for therapeutic purposes or for interaction with computers.
The new printable ink is made by dispersing the liquid gallium-indium in a non-metallic solvent using ultrasound, which breaks up the bulk liquid metal into nanoparticles. This nanoparticle-filled ink is compatible with inkjet printing systems.
The liquid-metal nanoparticles are initially coated with a protective layer of oxidised gallium. So after printing, the nanoparticles must be rejoined by applying light pressure, which makes the material conductive. You can activate only some sectors across the surface, suggesting that a standard film might be manufactured for many potential tailored applications.
Bonus: Made in Ukraine
On April 22, on the eve of the World Book and Copyright Day, the V International Arsenal Book Festival opened at Mystetskyi Arsenal in Kyiv. The biggest book event in Ukraine combines art and literature.
The program of the Arsenal Book Festival traditionally includes presentations of new editions, discussions, lectures, public interviews, readings and performances, open-air poetry and music programs. Cafe Europa, the central international stage, hosted 40 writers, speakers and artists from 12 countries. The first experimental art stage featured contemporary Ukrainian typography, calligraphy, printing samples.
More than 150 leading publishing houses and international partners took part in Arsenal Book Festival representing fiction, children, non-fiction, and art literature. The first translation of Quran was among the most significant announcements: it took translator Mykhailo Yakubovych five years to translate Quran into Ukrainian.
