Apparatus and method of marking polymer-based laminates |
摘要 |
A method of marking a polymer-based laminate (10) including a core layer (12), a cover layer (14) on at least one side of said core layer and an adhesive layer (16) acting between the core layer and the cover layer is provided. The core, adhesive and cover layers have different radiation transmission coefficients. The method comprises the step of selectively irradiating the laminate with laser radiation (12) having a fluence sufficient to mark the adhesive layer at selected locations while maintaining the cover layer intact. <IMAGE> |
