Laser Watermarking

Watermark images have low visibility under normal conditions and are highly visible when illuminated with a backlight. 


Unique watermarking applications

Microtrace Laser Watermarking for security and other official documents is done on synthetic papers, like PPG TESLIN®. No other laser-marking company has this capability.

If you do or can use a synthetic paper such as PPG TESLIN for your application, Laser Watermarking is a security feature that is customized, challenging to forge and can be verified simply. Laser Watermarking imaging can be customized with:

  • Barcodes
  • Microscopic alphanumeric serial numbers
  • Logos
  • Photographs
  • Custom security designs

Watermarking on synthetic paper made possible

Typical watermarking is not possible on synthetic papers (hydrophilic, polymeric and micro-porous structures like polyesters, polyvinyl halides, polyolefins and acrylics with micro-voiced structure) commonly used for security documents, because it is durable and difficult to tear.

With Microtrace’s unparalleled laser technology, synthetic paper is “watermarked” by deforming select portions of the micro-porous structure in a pattern, changing its light-transmission characteristics. With careful selection of laser parameters—wavelength, frequency, pulse duration and power level—selective distortion on synthetic papers can mostly be done sub-surface, without significant change to the paper’s visual appearance.
