For the HOW design conference, International Paper (IP) wanted to do something with invisible inks. They had about 4 weeks before the conference and came to OTTO for ideas. OTTO analyzed the situation and identified a few significant barriers to printing with invisible inks for the conference. The first was cost. The invisible inks were made by a single Japanese company. To test them, the minimum order was for 5lb bags of ink, which cost about $20,000 each. That’s a significant barrier to entry for a test project. The second was the nature of IP’s Accent™ paper. The whitening agents in the paper that help give it the brightness for which it is known include phosphorus and other chemicals. These chemicals interact poorly with invisible ink, causing less-than-ideal performance. And third, there was the element of time… specifically, not enough of it.
OTTO looked at the situation and came up with some creative ideas that played off this idea of invisible printing without needing to use invisible inks. But the HOW conference is an important one for designers. The solution needed to be about more than just printing technique. It needed to showcase the exceptional quality of Accent Opaque paper while also touching on a subject familiar and important to the designer audience.
