The process of manufacturing paper or fabric based wall coverings typically involves coating, printing, and pre-pasting steps. A backing material, often paper, fabric, or nonwoven, is first coated with a ground color using colored vinyl (PVC) or a similar substance. After this, patterns are applied through surface, gravure, silk screen, or rotary printing. The process usually concludes with a wet coating step. Once dried, the finished product is ready for final inspection and quality control.
Our M-Ray technology uses safe millimeter-wave signals to measure material properties without contact or ionizing radiation. It is especially suited for structured or multi-layer wall coverings, including those with foamed, embossed, or printed finishes.
Visual appearance is just as critical as material performance in wall coverings. The Edge-Vision-4.0-CURTAIN system delivers inline optical inspection, detecting surface flaws that might go unnoticed by weight or thickness measurements alone.
Installed after printing or final coating, it checks for pattern alignment, print defects, color inconsistencies, or surface contamination. A second unit can be positioned at the final inspection stage to ensure that edge defects and aesthetic issues are identified before winding or packaging.
