Can I tape the interlaced image to the back of the lenticular lens sheet?
Prints must be face mounted directly behind the lens material with 100% face contact. The material has a focal point directly behind the lens and any separation between the lens and the print will cause the image to be out of focus. You can use a spray mount adhesive for temporary mounting but an optically clear adhesive with a clear release liner is recommended for permanent results. One of the biggest learning curves will be in mounting the print to the back of the lens. This will take a little practice but you will get it soon thereafter.
