For transparent materials you can choose the "mirrored printing" option: we'll print your contents on the reverse side (on the back of the panel) and the graphic will still be visibile from the front.
Please note that:
There's no need to mirror your file, the mirror printing will be applied automatically
Clear plexiglass is printed on the back by default
Transparent adhesive materials are not printed on the glue side. In this way, the printed graphic can be seen correctly even when applied to the inside of glass surfaces
The glue of the adhesive material is opaque, the mirror printed graphic will therefore not be 100% transparent
If you need information also about the white printing on non-white material, you will find self-help with this article.
