Printing superimposed layers

This invention describes a method to create a multi-layered panel with precisely aligned images. It uses an assembly where a stencil layer with a release surface is sandwiched between a base material and a transparent top coating. After printing design and background layers onto the coating, a force removes the printed material and coating from the stencil areas, leaving the desired image adhered to the base material. The claims specify that the base material is transparent and the design is printed in reverse to be viewed correctly through it.

Why it matters: Digital printing precision and material science for coatings and release surfaces have advanced significantly since 2007. This simplifies achieving exact registration for superimposed layers.
