How do you ensure the stability of the template and that it doesn’t slip when it is only secured with tape?

Typically using the tape on the edges works fine. For additional stability, a double-sided adhesive is recommended, but as the mechanical forces tend to diffuse, not much strain is introduced on smaller pieces of tape.

When mounting the imprint template using tape on the edge, you have to place the tape under tension, so there is no movement of the imprint template itself. Placing the imprint template under tension will prevent slip.

The soft PVC is slightly adhesive by itself, so you can mount the imprinting template on it directly. However, the excessive resin can flow outside the imprinting template area. We, therefore, recommend using a protective/sacrificial foil on top.

Any resin waste tends to happen at the start of the imprint process. During the operation, the pressure will stabilize it during the imprint process itself.
