ARMOR Industrial Inks receives food contact certification from ISEGA

THREE years ago, ARMOR began formulating and producing industrial inks through its ARMOR Industrial Inks division (A2i).

“The guiding development principle of ARMOR Industrial Inks is inextricably linked to the fundamentals of the group: namely formulation expertise, innovation and respect for the environment,” said Hubert de Boisredon, CEO of ARMOR. All the inks are water based, providing them with excellent durability. Digital printing is ideal for small runs (customization, on-demand) at competitive rates, which the classical “analog” technologies are unable to achieve.

The A2i business is breaking new ground as its inks have received food contact certification from ISEGA. The purpose of this certification is to confirm the conformity of a component or finished product for use in food contact situations. It covers all the A2i inks developed for printing on porous surfaces for a limited duration of four hours.

“This food contact certification is fully in keeping with ARMOR's desire to offer products that comply with demands relating to the safety of goods, people and food,” said Miro Vanek, GM of A2i.

It's no accident. Hydrochromic ink color changes when wet

Most parents have done it but probably don't want to talk about it – that quick finger swoop inside a baby's diaper to see if it's wet and needs changing.

Let's be honest …

It's a little gross – and inconvenient – if you don't have a bottle of hand sanitizer around.

The innovators at CTI have introduced another “solutions powered by chemistry” breakthrough to address this problem and improve on present diaper market technology.

The company introduced Hydrochromic Wetness Indicator Ink and has been working with pioneer customers to commercialize the technology.

It's brilliant but straightforward: When dry, the ink appears yellow. When wet, the ink turns blue.

This unique chemistry detects moisture and changes color for substrates that need to be monitored for wetness, such as baby and adult diapers. It's highly sensitive to ambient humidity, so during the printing and converting production process; the Hydrochromic prints must be protected from water, liquid or vapor.

That sound daunting, but in the case of diaper manufacturing, it's not. First, the thin air permeable and semi-transparent plastic layer with the Hydrochromic ink can be reversed printed so that when it's combined with the other diaper layers, it's physically against the moisture absorbent material. This way, it truly takes a lot of wetness to change the color.

Commercially, there's no need for a separate offline process like the application of a wax stripe. CTI's Hydrochromic solvent ink prints like any other ink, so the design possibilities are endless. For instance, a diaper brand could print flowers that change from yellow to blue or a sun that change color so that it's obvious that the diaper needs a change.

CTI is the world's largest producer of thermochromic ink and manufactures other environmentally reactive technology, such as photochromic, pressure activated, fluorescing and glow-in-the-dark. CTI is an innovation company that supports the world's biggest brands and packaging printers.

Heat sensitive ink -- security and marketing sizzle

NEARLY everyone knows about cold-activated thermochromic ink. Chromatic Technologies Inc. (CTI) has been helping Coors Light turn the mountains blue at 46°F – the ideal consumption temperature – for years.

But did you know that heat-activated inks exist, too?

With these, the color turns to clear at the target temperature, whether it's from the heat of your fingers touching a print, or breathing on the print, or a microwaving a syrup bottle or other food package.

Common applications for heat sensitive or activated inks include

  • Document Security -- Touch or rub the printed ink text or design to show that a document is authentic. Great for checks and other official secure documents.
  • Safety Feature – Ensure that consumers know when microwaved or beverages are too hot to handle or taste, or when they're just the right temperature.
  • Hidden Messages or Images – Use a heavy coating of heat-sensitive thermochromic ink to cover up a yearbook cover photo, and watch amazed teens touch or rub to reveal the image again and again.

CTI is the world's largest producer of thermochromic ink and manufactures other environmentally reactive technology, such as photochromic, pressure activated, fluorescing and glow-in-the dark.
