Description
The project aims to replace the manual application of protective coatings within the watch manufacturing cycle with a digital printing process. This will be realized by pursuing three main objectives that reflect industry needs:
(i) develop a printable resin to ensure the desired protective function
(ii) identify a digital printing technology with the requested spatial definition down to 10 µm
(iii) ensure traceless removal of the protection, either by dissolution or preferably by peeling off or delamination.
By developing a printable ink based on a reversible photo-polymer that can be cured (hardened) with light and removed later via irradiation with a second wavelength of light without leaving traces.
