Invisible optical edge marking: Saint GobainRecent Research Landscape

Manual tracking of glass sheets during high-speed processing leads to identification errors and surface damage. This technology utilizes invisible matrix codes aligned to reference edges to automate traceability without compromising optical clarity.

What technical problems is Saint Gobain addressing in Invisible optical edge marking?

Unobtrusive glass identification failure

(5)evidences

Transparent or ceramic materials lack visible features for spatial orientation during processing. Precise identification and positioning prevent manufacturing alignment errors.

Product traceability aesthetic degradation

(3)evidences

Standard marking techniques compromise aesthetic integrity or reveal security features to unauthorized parties. Eliminating visual detection while maintaining traceability prevents counterfeiting and preserves material transparency.
