Shape-shifting trim panels
Proell KG - Booth A4275

Every year, companies like Pröll discover ways to do more with screen printing; lifting interior ambiance without lifting the cost. This year, the company is introducing its dual designs for film insert moulding, which allows trim panels to change from a realistic wood-effect finish to an aluminium finish at the touch of a button.

Thanks to the advances in chemical- and abrasion-resistant dual-cure screen printing lacquers, films can be decorated from both sides to create matt, gloss or 3D effects, or dual designs. For the latter, a transparent polycarbonate film is first surface decorated, then coated with a semi-transparent silver layer and finally overprinted with a thick line structure using the resistant Norilux DC dual-cure lacquer.

The second surface of the film can be decorated with a different pattern, realised by 4-colour screen printing with the new NoriCure IMS UV-curing inks. The first ink layer on the second surface is a semi-transparent black, to prevent a shine through of the image. The second image is then back-printed with a white-tinted adhesion promoter from the NoriPhan IMD/FIM ink range. Finally, the decorated film is 3D formed and back-moulded with a transparent polycarbonate. The result is that by backlighting the panel, the second surface becomes visible.
