Safe Technology

A Tektronix color printer uses unique solid ink technology to print in relief.

An infra-red technique (patented by SAFE), located at the end of the printer heats the parts of the document which needs to be made secure (for example, a check attached to a letter).

Under the heating effect, the melted ink penetrates the totality of the paper by capillarity. The document has then been printed recto/verso.

The Safe Answer to Forgery

In case of data attempted falsification (figures, date, recipient) :

• By mechanical erasure : since the ink impregnates the paper throughout its thickness, it can neither be erased, nor scraped without causing a hole in the paper
  
• By thermal shock : ink cannot be removed since it has penetrated the fibers of the paper
  
• By chemical erasure : according to cases, the inscriptions fade but do not disappear; the reactive paper does change color revealing the attempted fraud
