We describe a novel coating process for preserving and enhancing color images from ink jet prints. It involves stabilizing the printed image, followed by selective chemical interaction with the inks. The coating provides liquid, gas and UV light protection. It also changes the way light interacts with the original colorants. Untrained viewers (e.g. ordinary consumers) report the coated images a...

Printing silver nanoparticle inks to generate conductive structures for electronics on polymer substrates has gained increasing relevance in recent years. In this context, the Aerosol-Jet Technology is well suited to print silver ink on 3D-Molded Interconnect Devices (MID). The deposited ink requires thermal post-treatment to obtain sufficient electrical conductivity and adhesion. However, comm...
