Dichroic films appear in different colors depending on the viewing angle. So if you walk past a shop window covered with the iridescent adhesive film, for example, you will see the same surface in different colors. This is quite a spectacular effect and is therefore ideal for anything that needs to be an eye-catcher. For example, you can use a cutting plotter (with a tangential blade at 60°) to plot motifs or lettering from the film and apply them to the surface of your choice.
The important thing to remember with polyester film is that it should only be applied to smooth, firm and even surfaces and that it is better to apply it dry because the material is not particularly breathable. To put it more clearly: if you want to apply it wet, you should make sure that you carefully wipe out the water with a squeegee after positioning. This works particularly well on glass. However, any water remaining between the film and the glass hardly evaporates at all because it can hardly diffuse through the film. So you have to work really carefully. Water with a transfer liquid works better than pure water. Acrylic glass should only be covered if it is a tempered material. Untempered acrylic glass tends to outgas when the ambient temperature changes (when heated). As the film is not open to diffusion, gas bubbles will form under the film in this case.
The transparent film is ideal for transparent substrates. The transparency is well maintained and the film acts as a kind of color filter. Aslan calls the color variants "Nebula" and "Solar". This refers to the color changes from yellow to pink (Solar) and from pink to blue (Nebula). When sticking them on, make sure that you stick on adjacent foils in the same direction. Otherwise the color changes will not be homogeneous or parallel when viewed. The running directions should also not be applied at right angles to each other, as this would severely disrupt the beautiful visual effect of the film.
When plotting this film with a Cameo cutting plotter, we have had good experiences with the following settings:
- Vinyl glossy
- Knife: 2
- Pressure: 10
- Speed: 1
